Picking a PCB assembly supplier is a trust decision. Here's the verification-first rubric — what evidence to demand and how to tell a real manufacturer from a risk.
A field guide to the warning signs that separate a reliable China PCBA partner from a costly mistake, plus the concrete checks that de-risk each one.
The exact files, fields, and answers a contract manufacturer needs to price your board accurately on the first pass, plus the gaps that trigger re-quotes.
AOI, X-ray, in-circuit testing, and functional testing each catch different faults. Here's what every method finds, its blind spots, and when to use it.
What PCB DFM actually checks, why it matters, and a designer-friendly checklist to catch manufacturability issues before your board hits the assembly line.
How a bare board becomes a working assembly, stage by stage, with the SMT and through-hole steps and the inspection checks that catch defects.
A plain-English breakdown of what actually drives PCB assembly cost, with worked examples, a fill-in cost worksheet, and an RFQ checklist for comparing quotes.
ISO 9001, IPC-A-610, and UL each prove something different about a PCB assembler. Here's what each one actually means and how to read it during vetting.
The per-board price is rarely the price you pay. Here are the eight hidden costs in overseas PCB assembly and the contract terms that keep them out of your project.
Everything a hardware team needs to outsource PCB assembly to China the right way: supplier vetting, file prep, quality control, cost, logistics, and risk.
IPC-A-610 sets the visual acceptance criteria for electronic assemblies across three reliability classes. Here's what each class means and how to pick the right one.
The exact files an assembler needs, how to format your Gerbers, BOM, and pick-and-place data, and the common gaps that stall a PCBA quote before it ever starts.
How to source electronic components for PCB assembly without paying for counterfeit parts, blown lead times, or a BOM your assembler can't actually buy.
Most PCB delays start in the design file, not on the line. Here are the 10 DFM mistakes that trigger holds, and how to clear them before you submit.
A practical 10-point checklist for selecting a PCB assembly manufacturer, written for hardware founders and engineers who want boards that actually work in the field.
Counterfeit parts cost you scrap, field failures, and recalls. Here are 7 warning signs that a component is fake, and the sourcing and test habits that stop them.
