In SMT PCB assembly, solder paste printing is often the make-or-break step. Solder Paste Inspection (SPI) technology provides the critical quality control needed before component placement. This in-depth guide explains how 3D SPI works, its real benefits, and how it helps manufacturers like Vonkka PCB deliver superior results.
PCBA testing is the inspection and verification process used to confirm that an assembled circuit board is built correctly and works as intended. This guide explains the main PCBA testing methods, what defects they can detect, when to use each one, and how testing affects quality, cost, and lead time.
This article explains how to pre-bake flexible PCBs before assembly and how to manage reflow so the board stays dry, flat, and reliable throughout soldering.
