A Comprehensive Guide to the Entire PCBA Process: The Precision Manufacturing Journey from Bare Board to Finished Product

A qualified PCBA must undergo six core processes:
Solder Paste Printing: High-Precision Steel Stencil Prints Solder Paste onto Solder Pads
SMT Mounting: Pick-and-place machines position components with micrometer-level precision.
Reflow Soldering: High-Temperature Curing to Form Reliable Electrical Connections
AOI Automated Optical Inspection: Detects defects such as cold solder joints, misalignment, and missing component placement.
DIP Component Insertion and Wave Soldering: Completing the Soldering of Through-Hole Components
ICT/FCT functional testing, burn-in testing, and three-proof coating
Rigorous quality control throughout the entire process ensures stable operation under extreme conditions such as high and low temperatures, vibration, and humidity, making it one of the most critical steps in electronic manufacturing.
