MLCC and resistor spot quotes are jumping 2x-5x. Learn why this is not a clean shortage story and how PCBA buyers should protect BOMs, alternates and quote windows through late August.

AI can speed PCB design but Gerber BOM CPL assembly polarity sourcing risk and functional test requirements still need PCBA review before quote and build.

Component and freight volatility mean a 2026 PCBA RFQ needs more than Gerbers. Add approved alternates, quote windows, and sourcing rules before you send it.

A PCBA quote is faster and safer when your Gerber, BOM, CPL, alternates, lifecycle notes, and test requirements arrive together. Here is what to prepare.

Skipping functional testing on your PCBA prototype can cost far more than the test itself. Here's how to decide when you need it — and when you don't.

Why does your 100Ω differential pair come back as 93Ω? A process engineer's breakdown of every manufacturing variable that shifts impedance — dielectric thickness, Dk variation, etch compensation, copper uniformity — with real numbers and actionable controls.
