A medical device maker lost $240K when SAC305 joints cracked under thermal cycling—because the solder's solidus was 30°C below the operating peak. Here's...

A field failure in an agricultural sensor array caused a $120k recall—root cause: screw terminals loosened due to vibration. This guide compares crimping,...

A 10 Gbps PCIe Gen4 channel failed compliance testing—root cause: 0.25mm microvias with 1:8 aspect ratio caused 12% impedance discontinuity. This article...

A medical imaging device failed EMI compliance—root cause: using FFC instead of FPC in a 45° flex zone. Here’s how to choose between FFC (Flat Flex Cable)...

A military radar array failed after 48 hours in desert testing—root cause: solder mask delamination at 125°C. Dry film outperforms LPI in thermal cycling...

A PCB BOM is the document that tells purchasing and assembly exactly what to buy, place, and verify. This guide explains the required fields, sourcing details, file formats, and review steps that prevent line-down delays, wrong-part substitutions, and expensive rework.
