PCB Manufacturing and Assembly in China
CCB helps buyers source bare PCBs and assembled boards in China against controlled fabrication and assembly files. Define the board, component sourcing policy and test coverage before comparing quotes; a visually acceptable assembly is not proof that the circuit works.
We reply the same working day to confirm receipt and arrange next steps.
What to send us for a quote
Send Gerber or ODB++ files, drill data, stack-up, board thickness, copper and finish requirements, fabrication notes, BOM with manufacturer part numbers, pick-and-place data, assembly drawings, quantities, firmware and test instructions. State approved alternatives, traceability needs and delivery place.
What drives the cost?
Layer structure, laminate, controlled impedance, hole technology, surface finish, panel yield and test fixtures affect fabrication cost. Component availability, authorised sourcing, substitutions, assembly operations and programming drive assembly cost. Compare the same BOM revision and test coverage.
How is quality controlled?
Agree the revision and product class for IPC-A-600 bare-board acceptability and IPC-A-610 assembly acceptability as applicable. Approve first articles, component identity and polarity, then agree in-process AOI, X-ray where needed and electrical or functional tests. Pre-shipment AQL sampling under ISO 2859-1 complements the test plan; it does not replace it.
What affects lead time?
Component shortages, alternative approvals, engineering queries, test fixture readiness, firmware changes and first-article rework determine the schedule. Confirm what happens to unused components and whether the next order can use the same approved parts.
What should UK importers check?
Confirm the commodity code, customs value, origin, importer of record and EORI with your broker. Duty depends on classification and applicable trade measures. Check product-specific UKCA or CE requirements where relevant; a component or factory certificate does not establish conformity of the finished product. Great Britain and Northern Ireland can follow different routes.
Where can I see relevant factory profiles?
Use the industry directory as a starting point, then check the profile’s evidence and verification status. A listing is not proof of capability for your drawing.
Standards and regulatory sources
Check the applicable market and agreed edition; naming a standard is not a certificate of compliance.
What you get
- A UK sourcing company with its own team in China, coordinating your brief and supplier questions.
- A written specification, acceptance criteria and delivery responsibilities agreed before commitment.
- Evidence and open questions recorded for your approval.
What we do
- Review your files and intended use; clarify specification, inspection scope and delivery.
- Compare supplier proposals or agree the check scope, including exclusions and required evidence.
- Coordinate samples or on-site work, record findings and obtain your approval before the next commitment.
- Arrange the agreed production follow-up, inspection, report and delivery paperwork.
Cambridge China Bridge in brief
- Buying from Chinese factories since 2021 (the company was incorporated in September 2022), for our own businesses and for clients on the same terms.
- Our own staff are based in China, at two bases: the Pearl River Delta (Guangzhou, Shenzhen, Dongguan) and the Yangtze River Delta (Shanghai, Zhejiang, Jiangsu). They visit factories themselves.
- Quotes to suit how you buy: one delivered price, or an itemised quote with the factory cost, freight, duty and our service fee shown separately. Open-book detail is available on request.
- Audits and inspections are usually included in the quote for an order placed with us; complex checks that need a third party are charged extra, agreed first.
- Orders run from a first trial to scheduled full containers; the factory’s own minimum is stated in the quote.
- In one project, a UK EV charging operator cut unit cost by 70% and scaled 3× faster. In another, a multi-site Cambridge café chain saved 50% on packaging.
- A UK company in Cambridge and London: Cambridge China Bridge is the trading name of Piggy Pineapple Ltd, company number 14385590.
- Send 1–3 products you buy now and what you pay. We compare the same specification, quantity, inspection and delivery scope to establish a cost benchmark.
- A reference call with a past client can be arranged, with that client’s agreement.
How we charge
Quotes to suit how you buy: one delivered price, or an itemised quote with the factory cost, freight, duty and our service fee shown separately. Open-book detail is available on request.
Our margin is included in the quoted price or shown separately as a service fee. The service fee depends on the agreed scope, including products, samples, inspections and ongoing supply.
Questions buyers ask
Does an IPC inspection prove UK compliance?
No. IPC acceptance criteria concern workmanship. The finished product may also need safety, EMC, radio or substance compliance evidence, depending on its function and market.
What do you need before quoting?
Send Gerber or ODB++ files, drill data, stack-up, board thickness, copper and finish requirements, fabrication notes, BOM with manufacturer part numbers, pick-and-place data, assembly drawings, quantities, firmware and test instructions. State approved alternatives, traceability needs and delivery place.
What changes the price?
Layer structure, laminate, controlled impedance, hole technology, surface finish, panel yield and test fixtures affect fabrication cost. Component availability, authorised sourcing, substitutions, assembly operations and programming drive assembly cost. Compare the same BOM revision and test coverage.
How do you check the order?
Agree the revision and product class for IPC-A-600 bare-board acceptability and IPC-A-610 assembly acceptability as applicable. Approve first articles, component identity and polarity, then agree in-process AOI, X-ray where needed and electrical or functional tests. Pre-shipment AQL sampling under ISO 2859-1 complements the test plan; it does not replace it.
When can the goods or report be ready?
Component shortages, alternative approvals, engineering queries, test fixture readiness, firmware changes and first-article rework determine the schedule. Confirm what happens to unused components and whether the next order can use the same approved parts.
