Backplane PCB manufacturing succeeds or fails on stackup control, connector strategy, press-fit discipline, impedance targets, and test access. This buyer-focused guide explains what to define before fabrication and assembly release.

ICT and functional test catch different PCB assembly failures. Learn when each test pays for itself and how to specify test coverage.

Solder paste inspection is the first serious quality gate in SMT assembly. This guide explains what SPI catches before reflow, which limits buyers should define, and how to use SPI data alongside AOI, X-ray, stencil control, and functional test.

Crimp pull testing is one of the fastest ways to check whether a wire-to-terminal termination has real mechanical margin or only looks acceptable. This guide explains what pull testing proves, what it does not prove, and what buyers should define before approving a wire harness build.

Selective soldering is often the right process for mixed-technology PCB assemblies, but buyers still approve it with vague notes and weak controls. This guide explains when selective soldering beats wave or hand soldering, what process windows matter, and what OEM teams should define before release.

Clean-looking boards can still carry ionic residue that drives leakage, dendrites, corrosion, and coating failures. This guide shows buyers when to require cleanliness controls, which test methods answer which question, and what to lock before release.
