Solder Paste Guide: Type, Alloy, Storage, Printing, and Reflow Control

Solder paste is not just powdered alloy in flux. Its alloy, particle size, metal load, storage control, stencil behavior, and reflow profile decide whether SMT assembly runs cleanly or fills the defect log with opens, bridges, voids, and head-in-pillow failures.

BOM Sourcing for PCB Assembly: How to Control Cost, Lead Time, and Substitution Risk

BOM sourcing for PCB assembly is not just buying parts. It is a controlled process for availability checks, approved alternates, counterfeit avoidance, lifecycle review, and landed-cost planning before the SMT line starts.
