Terms of Service

1.1 Parties. These Terms of Service ("Terms") constitute a legally binding agreement between Vosnor, a PCB assembly manufacturer headquartered in Humen, Dongguan, Guangdong, China ("Vosnor," "we," "us," or "our"), and the business entity or individual ("Customer," "you," or "your") that accesses our website, submits an enquiry, or enters into a commercial agreement with us.

1.2 Scope. These Terms apply to all services offered by Vosnor, including but not limited to customer-specific PCBA engineering and development, SMT assembly, DIP/THT assembly, turnkey PCBA manufacturing, prototype-to-volume production, BOM and component sourcing, testing, and quality documentation services.

1.3 B2B Relationship. Vosnor provides services exclusively to business customers. By engaging with Vosnor, you represent and warrant that you are acting in a professional or commercial capacity and not as a consumer.

1.4 Acceptance. By submitting an enquiry, signing a purchase order, or otherwise engaging Vosnor's services, you confirm that you have read, understood, and agree to be bound by these Terms. If you do not agree, you must not use our services.

2.1 Service Description. Vosnor is a factory-direct PCBA engineering and manufacturing partner. Our core services include:

• Customer-Specific PCBA Engineering & Development -- translating customer requirements, BOM, board outlines, samples, and specifications into production-ready PCB assembly designs.
• SMT PCBA Assembly -- surface-mount technology assembly with precise component placement for high-density boards.
• DIP/THT Assembly -- through-hole assembly for mechanically robust connections, including mixed-technology boards.
• Turnkey PCBA Manufacturing -- BOM sourcing, assembly, programming, testing, and documentation under one contract.
• Prototype-to-Volume Production -- support from prototype and NPI stages through pilot runs to volume manufacturing.

2.2 Scope Limitations. Vosnor does not manufacture complete finished end-user electronic products as a standalone offering, does not trade standalone electronic components as a primary business line, and does not own bare PCB board fabrication capability. Services are limited to those expressly agreed in writing for each project.

2.3 Service Modifications. Vosnor reserves the right to modify, update, or discontinue any service offering at any time. Changes will not affect orders already confirmed in writing prior to the modification.

3.1 Enquiry Process. To receive a quotation, the Customer must provide accurate and complete technical information, which may include but is not limited to: BOM (Bill of Materials), PCB Gerber files or board outlines, component specifications, samples or reference assemblies, target quantities, quality requirements, and applicable regulatory or compliance standards.

3.2 Quotation Basis. All quotations are prepared by Vosnor following a review of the Customer's submitted requirements. Vosnor will not provide pricing, production, or delivery estimates prior to completing a review of the Customer's BOM, drawings, samples, and specifications. Quotations are indicative only until confirmed in a written purchase order accepted by Vosnor.

3.3 Quotation Validity. Unless otherwise stated in writing, quotations are valid for thirty (30) calendar days from the date of issue. Vosnor reserves the right to revise or withdraw a quotation at any time before the Customer's written acceptance, particularly in the event of material cost changes, component availability changes, or exchange rate fluctuations.

3.4 No Commitment. Submission of an enquiry or receipt of a quotation does not create any binding obligation on either party. A binding agreement is only formed upon Vosnor's written acceptance of a formal purchase order.

4.1 Order Placement. Orders must be placed by submitting a written purchase order referencing the applicable Vosnor quotation number, agreed specifications, quantity, pricing, and delivery terms. Verbal orders are not binding.

4.2 Order Acceptance. An order is only accepted when Vosnor issues a written order confirmation. Vosnor reserves the right to decline any order at its discretion without liability to the Customer.

4.3 Order Changes. Any changes to a confirmed order -- including quantity, specifications, components, or delivery schedule -- must be submitted in writing. Vosnor will assess the impact of changes on pricing, lead time, and feasibility. Changes are not binding until confirmed by Vosnor in writing. The Customer acknowledges that changes may result in additional costs and extended lead times.

4.4 Order Cancellation. Orders may not be cancelled after Vosnor has commenced procurement or production without Vosnor's written consent. In the event of an approved cancellation, the Customer shall reimburse Vosnor for all reasonable costs incurred up to the point of cancellation, including materials procured, work in progress, and any non-cancellable component orders.

5.1 Accuracy of Information. The Customer is solely responsible for the accuracy, completeness, and suitability of all technical information, designs, specifications, BOM data, and materials provided to Vosnor. Vosnor will manufacture to the specifications provided and is not responsible for defects or failures arising from errors in Customer-supplied data.

5.2 Design for Manufacturability. While Vosnor may offer DFM (Design for Manufacturability) feedback as part of the NPI process, the Customer retains full responsibility for the final design. DFM feedback from Vosnor is advisory only and does not constitute a warranty that the design is fit for purpose.

5.3 Regulatory Compliance. The Customer is responsible for ensuring that the products and assemblies ordered comply with all applicable laws, regulations, and standards in the target markets, including import/export controls, product safety regulations, and any required certifications. Vosnor may provide CE and FCC compliance support where expressly agreed and where a valid test report exists for the specific product; however, the Customer remains the responsible party for regulatory compliance.

5.4 Intellectual Property Ownership. The Customer warrants that it has full rights to use, disclose, and have manufactured all designs, schematics, firmware, and specifications provided to Vosnor, and that doing so does not infringe the intellectual property rights of any third party.

5.5 Timely Approvals. The Customer shall provide timely approvals, feedback, and responses to Vosnor's requests. Delays in Customer approvals may result in corresponding delays to production schedules, for which Vosnor shall not be liable.

6.1 Pricing. All prices are as stated in the applicable Vosnor quotation and confirmed purchase order. Prices are exclusive of taxes, duties, freight, insurance, and any other charges unless expressly stated otherwise in the quotation.

6.2 Currency. Unless otherwise agreed in writing, all prices are quoted and invoiced in United States Dollars (USD). Vosnor reserves the right to adjust pricing if significant exchange rate movements occur between quotation and order confirmation.

6.3 Payment Terms. Payment terms will be specified in the quotation and confirmed order. Unless otherwise agreed in writing, standard payment terms require a deposit prior to production commencement, with the balance due prior to or upon shipment. Specific payment schedules will be agreed on a per-order basis.

6.4 Late Payment. Invoices not paid by the due date may incur interest at a rate of 1.5% per month (or the maximum rate permitted by applicable law, if lower) on the outstanding balance. Vosnor reserves the right to suspend production or withhold shipment of goods in the event of overdue payments.

6.5 Taxes & Duties. The Customer is responsible for all applicable taxes, customs duties, import fees, and similar charges imposed by any governmental authority in connection with the purchase, import, or use of goods manufactured by Vosnor.

6.6 Price Adjustments. Vosnor reserves the right to adjust pricing for confirmed orders where there are significant and unforeseen increases in raw material costs, component prices, or logistics costs. Any such adjustment will be communicated to the Customer in writing prior to implementation, and the Customer may cancel the affected order within five (5) business days of notification without penalty, subject to reimbursement of costs already incurred.

7.1 Delivery Estimates. Any production or delivery timelines communicated by Vosnor are estimates only and are subject to the timely receipt of all required Customer materials, approvals, and payments. Vosnor will not provide binding delivery commitments prior to reviewing the Customer's complete BOM, drawings, samples, and specifications.

7.2 Shipping Terms. Unless otherwise agreed in writing, goods are shipped Ex Works (EXW) Vosnor's facility in Dongguan, Guangdong, China, in accordance with the latest edition of Incoterms. Risk of loss and title transfer to the Customer upon handover to the carrier at Vosnor's facility.

7.3 Freight & Insurance. Unless otherwise agreed, the Customer is responsible for arranging and paying for freight, insurance, and all associated logistics costs. Vosnor may arrange shipping on the Customer's behalf as a convenience service; in such cases, actual freight costs will be passed through to the Customer.

7.4 Partial Shipments. Vosnor reserves the right to make partial shipments where agreed with the Customer, or where circumstances reasonably require. Each partial shipment may be invoiced separately.

7.5 Delivery Delays. Vosnor shall not be liable for delays in delivery caused by circumstances beyond its reasonable control, including but not limited to component shortages, logistics disruptions, force majeure events, or delays attributable to the Customer. In such circumstances, Vosnor will notify the Customer as soon as reasonably practicable and will use reasonable efforts to minimise the impact of the delay.

8.1 Quality Standards. Vosnor operates under an ISO 9001 certified quality management system and manufactures assemblies using RoHS-compliant materials. Quality standards applicable to a specific order will be as agreed in the relevant purchase order and associated specifications.

8.2 Inspection & Testing. Vosnor performs quality inspection and testing as part of its standard manufacturing process, which may include automated optical inspection (AOI), in-circuit testing (ICT), and functional testing as applicable and agreed for each order. Test coverage and acceptance criteria will be defined in the order specifications.

8.3 Documentation. Vosnor provides quality documentation and traceability records for each order. The specific documentation package will be agreed upon at the time of order placement.

8.4 Customer Inspection. The Customer is responsible for inspecting goods upon receipt. Any claims for visible defects, shortages, or incorrect goods must be submitted to Vosnor in writing within fourteen (14) calendar days of receipt of the goods. Claims submitted after this period may not be accepted.

8.5 Defect Claims. For defects not discoverable upon reasonable inspection at the time of receipt, claims must be submitted in writing within thirty (30) calendar days of the date on which the Customer first discovered or reasonably should have discovered the defect. Vosnor's liability for accepted defect claims is limited to, at Vosnor's election, repair, replacement, or a credit note for the affected units, subject to the limitations set out in Section 12.

8.6 Exclusions. Warranty and defect claims do not apply to defects arising from: Customer-supplied designs, specifications, or components; misuse, mishandling, or improper storage by the Customer or end-user; modifications made by parties other than Vosnor; or normal wear and tear.

9.1 Customer IP. All intellectual property rights in designs, schematics, firmware, specifications, and other materials provided by the Customer to Vosnor remain the exclusive property of the Customer. Vosnor is granted a limited, non-exclusive licence to use such materials solely for the purpose of fulfilling the Customer's order.

9.2 Vosnor IP. All intellectual property rights in Vosnor's manufacturing processes, production methodologies, tooling, fixtures, and know-how remain the exclusive property of Vosnor. Nothing in these Terms grants the Customer any rights in Vosnor's proprietary processes or methods.

9.3 Custom Engineering Work. Where Vosnor performs customer-specific engineering or development work, ownership of the resulting deliverables (such as production-ready design files) will be as expressly agreed in writing between the parties. In the absence of a written agreement, such deliverables remain the property of Vosnor until full payment has been received, at which point ownership transfers to the Customer.

9.4 Third-Party IP. The Customer warrants that the use of any Customer-supplied designs, components, firmware, or specifications does not infringe any third-party intellectual property rights. The Customer shall indemnify and hold Vosnor harmless against any claims, losses, or expenses arising from any such infringement.

10.1 Mutual Obligation. Each party ("Receiving Party") agrees to keep confidential all non-public information disclosed by the other party ("Disclosing Party") in connection with these Terms or any order, including but not limited to technical specifications, designs, BOM data, pricing, business plans, and customer information ("Confidential Information").

10.2 Use Restriction. The Receiving Party shall use Confidential Information solely for the purpose of performing its obligations under these Terms and shall not disclose it to any third party without the prior written consent of the Disclosing Party, except to employees or subcontractors who have a need to know and are bound by equivalent confidentiality obligations.

10.3 Exceptions. Confidentiality obligations do not apply to information that: (a) is or becomes publicly available through no fault of the Receiving Party; (b) was already known to the Receiving Party prior to disclosure; (c) is independently developed by the Receiving Party without use of the Confidential Information; or (d) is required to be disclosed by law or court order, provided the Receiving Party gives prompt written notice to the Disclosing Party where legally permissible.

10.4 Duration. Confidentiality obligations under this section survive termination of the business relationship for a period of five (5) years.

10.5 NDA. Where a separate Non-Disclosure Agreement (NDA) has been executed between the parties, the terms of that NDA shall govern confidentiality obligations to the extent they are more specific or more protective than this section.

11.1 Vosnor Warranty. Vosnor warrants that goods manufactured by Vosnor will conform to the agreed written specifications at the time of shipment, and that manufacturing services will be performed with reasonable skill and care.

11.2 Warranty Period. Unless otherwise agreed in writing, Vosnor's warranty period is ninety (90) days from the date of shipment from Vosnor's facility.

11.3 Disclaimer. To the maximum extent permitted by applicable law, Vosnor makes no representations or warranties beyond those expressly stated in these Terms. All implied warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement, are hereby expressly disclaimed.

11.4 No Fitness Warranty. Vosnor does not warrant that the goods or services will be fit for any particular end-application, regulatory environment, or end-market unless expressly agreed in writing for that specific application. The Customer is responsible for determining the suitability of Vosnor's goods and services for its intended use.

11.5 Certification Disclaimer. Vosnor holds ISO 9001 certification and manufactures using RoHS-compliant materials. Vosnor does not hold and does not claim ISO 13485, IATF 16949, UL, FDA, AS9100, or any other certification not expressly stated. CE and FCC compliance support is available only where expressly agreed and where a valid certificate or test report exists for the specific product.

12.1 Indirect Damages. To the maximum extent permitted by applicable law, Vosnor shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including but not limited to loss of profits, loss of revenue, loss of business, loss of data, or loss of goodwill, arising out of or in connection with these Terms or any order, even if Vosnor has been advised of the possibility of such damages.

12.2 Aggregate Cap. Vosnor's total aggregate liability to the Customer under or in connection with these Terms or any order, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, shall not exceed the total amount paid by the Customer to Vosnor under the specific order giving rise to the claim in the twelve (12) months preceding the event giving rise to the claim.

12.3 Essential Basis. The Customer acknowledges that the limitations of liability set out in this section reflect a reasonable allocation of risk between the parties and are an essential element of the basis of the bargain between the parties. Vosnor would not have entered into these Terms without these limitations.

12.4 Exceptions. Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be limited or excluded by applicable law.

13.1 Customer Indemnity. The Customer shall indemnify, defend, and hold harmless Vosnor and its directors, officers, employees, and agents from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable legal fees) arising out of or in connection with: (a) the Customer's breach of these Terms; (b) inaccurate or incomplete specifications, designs, or BOM data provided by the Customer; (c) any claim that Customer-supplied materials infringe a third party's intellectual property rights; (d) the Customer's use, resale, or distribution of goods manufactured by Vosnor; or (e) the Customer's violation of any applicable law or regulation.

A "Force Majeure Event" means any event beyond the reasonable control of a party, including but not limited to acts of God, natural disasters, epidemics or pandemics, war, terrorism, civil unrest, government actions, trade embargoes, sanctions, fires, floods, power outages, critical component shortages due to global supply chain disruptions, or failures of third-party suppliers or logistics providers.

14.2 Effect. Neither party shall be in breach of these Terms or liable for any delay or failure to perform its obligations to the extent that such delay or failure is caused by a Force Majeure Event, provided that the affected party: (a) notifies the other party in writing as soon as reasonably practicable after the Force Majeure Event begins; (b) uses reasonable efforts to mitigate the impact of the event; and (c) resumes performance as soon as reasonably practicable after the Force Majeure Event ceases.

14.3 Extended Force Majeure. If a Force Majeure Event continues for more than sixty (60) consecutive days, either party may terminate the affected order upon written notice, without liability to the other party, except that the Customer shall pay for all work completed and costs reasonably incurred by Vosnor up to the date of termination.

15.1 Termination for Cause. Either party may terminate any outstanding order or business relationship immediately upon written notice if the other party: (a) commits a material breach of these Terms and fails to remedy that breach within thirty (30) days of receiving written notice specifying the breach; (b) becomes insolvent, enters into administration, receivership, or liquidation; or (c) engages in fraudulent or unlawful conduct.

15.2 Effect of Termination. Upon termination of an order or the business relationship: (a) all outstanding payment obligations become immediately due and payable; (b) each party shall return or destroy the other party's Confidential Information upon request; (c) provisions of these Terms that by their nature should survive termination (including confidentiality, intellectual property, limitation of liability, indemnification, and governing law) shall continue in full force and effect.

15.3 No Liability for Lawful Termination. Termination of these Terms in accordance with this section shall not give rise to any liability on the part of the terminating party, except for payment obligations already accrued.

16.1 Governing Law. These Terms and any disputes arising out of or in connection with them shall be governed by and construed in accordance with the laws of the People's Republic of China, without regard to its conflict of law provisions, unless otherwise agreed in a separate written agreement between the parties.

16.3 Arbitration. If the dispute is not resolved through negotiation within the period specified in clause 16.2, either party may refer the dispute to binding arbitration administered by the China International Economic and Trade Arbitration Commission (CIETAC) in accordance with its then-current arbitration rules. The arbitration shall be conducted in English, and the seat of arbitration shall be Guangzhou, China. The decision of the arbitral tribunal shall be final and binding on both parties.

16.4 Interim Relief. Nothing in this section prevents either party from seeking urgent interim or injunctive relief from a court of competent jurisdiction to protect its intellectual property rights or Confidential Information pending resolution of a dispute.

17.1 Amendments. Vosnor reserves the right to update or amend these Terms at any time. The updated Terms will be published on Vosnor's website with a revised effective date. Continued engagement with Vosnor after the effective date of any amendment constitutes acceptance of the revised Terms. For orders already confirmed prior to the effective date of an amendment, the Terms in force at the time of order confirmation shall apply.

17.2 Entire Agreement. These Terms, together with any applicable quotation, purchase order, and any separately executed written agreements (such as NDAs or framework supply agreements), constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior negotiations, representations, and agreements.

17.3 Severability. If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court or arbitral tribunal of competent jurisdiction, that provision shall be modified to the minimum extent necessary to make it enforceable, or severed if modification is not possible, and the remaining provisions shall continue in full force and effect.

17.4 Waiver. No failure or delay by either party in exercising any right under these Terms shall constitute a waiver of that right. A waiver of any breach shall not be deemed a waiver of any subsequent breach of the same or any other provision.

17.5 Assignment. The Customer may not assign or transfer any rights or obligations under these Terms without Vosnor's prior written consent. Vosnor may assign its rights and obligations to an affiliate or successor entity without the Customer's consent, provided that such assignment does not materially affect the Customer's rights under these Terms.

17.6 Relationship of Parties. The parties are independent contractors. Nothing in these Terms creates a partnership, joint venture, agency, employment, or franchise relationship between the parties.
