PCB & PCBA from One Factory Workflow Find Your Product Route First.
YC PCB YC PCB helps purchasing and engineering teams reduce supplier risk by matching each PCB project to the right production route: fast standard PCB, engineering multilayer PCB, or high-difficulty PCB / PCBA review.
Factory-direct communication means DFM, fabrication, SMT, AOI, E-test, packing, and delivery records stay inside one workflow instead of being passed between middlemen.
Choose Your PCB Product Route First
Buyers need to know quickly whether we can make the product. Start here, then review lead time, DFM process, certifications, and RFQ details.
Fast Standard PCB
For standard FR4, aluminum PCB, copper base PCB, LED PCB, and simple double-sided boards.
Engineering Multilayer PCB
For multilayer PCB, HDI PCB, gold finger PCB, impedance control PCB, and industrial electronics.

YC PCB's PCBA route is designed to reduce this coordination load. If a component is short, the project team can adjust purchasing priority, suggest an approved substitute path, or align SMT scheduling before the delay becomes a shipment problem.
PCB supplier + component buyer + assembly shop + test vendor + logistics, often with unclear responsibility when a part is missing.
Gerber, BOM, SMT plan, AOI / X-ray / FCT scope, packing, and shipment are discussed in one RFQ route.
Lower communication load, faster exception handling, and clearer ownership when PCBA lead time changes.

Estimate Production Days After Choosing Product Type
This estimator is for RFQ screening only. Final lead time still requires Gerber review, material confirmation, production route approval, and payment confirmation.
Standard FR4 route with complete files and in-stock material. Final date depends on DFM approval and production slot.
DFM Review Explains Whether Your Design Is Safe to Produce
We review manufacturability, material route, stack-up feasibility, copper balance, assembly risk, and testing requirement before confirming the final lead time.

Why Some RFQs Get Delayed — and How to Avoid It
A complete first message can reduce quotation time sharply. These are the most common reasons a PCB or PCBA RFQ cannot be confirmed immediately.
Common RFQ Delay Reasons
Gerber without drill data can block hole-size, via, and plating review.
HASL, ENIG, OSP, and gold finger requirements change cost, lead time, and process route.
Multilayer and impedance boards need stack-up, dielectric, copper, and reference-plane information.
PCBA schedule depends on component availability. Substitutes require customer approval.
Fast RFQ Flow
Send Gerber + drill files
PDF drawings or ODB++ are helpful for multilayer, HDI, and impedance boards.
State one application sentence
Example: LED driver board, automotive lighting PCBA, industrial controller, camera FPC.
Add quantity, lead-time target, and destination country
This helps us check production slot and logistics route early.
Complete files + clear product type + quantity + delivery target.
Certifications & Quality Commitments for Procurement Review
Certification is not just decoration. It helps procurement teams verify quality systems, compliance route, material documents, and inspection standards before supplier approval.
How can I confirm the boards meet my specification?
- ✓ IPC-A-600 inspection reference can be used for bare PCB acceptance.
- ✓ Multilayer and HDI projects can add electrical test and stack-up related records.
- ✓ First article inspection notes can be aligned before batch shipment.

Why Choosing YC PCB Is Easier to Defend Internally
A purchasing manager needs more than a low unit price. They need a supplier choice that can be explained to engineering, quality, and management if the project becomes urgent or complex.
Quality instability risk
Trace to production stage, inspection record, and process route instead of answering “we do not know.”
Delivery delay risk
Lead time is tied to product route, file completeness, material availability, and DFM status.
Technical support risk
Engineers review stack-up, copper, impedance, bend zone, or BOM risks before production starts.
Evidence Your Engineering and Quality Teams Can Accept
Buyers often need to justify a supplier choice internally. This section turns sales claims into operational evidence that engineering, quality, and management can evaluate.
Will the factory find design risks before production?
Use the DFM checklist and flow to show that file completeness, drill data, stack-up, copper balance, impedance, solder mask, and BOM risks are reviewed before production approval.
Can delivery and quality claims be verified?
Use the tracked-order breakdown, on-time definition, certificate slots, inspection record sample, and RMA response path as evidence for supplier approval.
What happens when a project changes urgently?
Factory-direct communication reduces the delay caused by middlemen. Engineering can re-check stack-up, material, panelization, BOM substitutions, and production slot in one workflow.
Factory-Direct vs Trading-Company Mode
The difference is not only price. It affects DFM speed, design-change cycles, quality traceability, PCBA coordination, and quotation transparency.
| Decision Factor | Factory-Direct YC PCB | Trading-Company Mode | Buyer Impact |
|---|---|---|---|
| Equipment ownership | Factory-owned process and inspection equipment such as drilling, AOI, electrical testing, CNC/routing, and SMT-related stations can be shown during supplier review | Testing and production proof may depend on outsourced factories, with slower access to records | cURL Too many subrequests by single Worker invocation.
