To ensure the delivery of high-quality and dependable PCB assemblies, it is essential to perform inspections at various stages of the manufacturing and assembly process in order to eliminate surface defects. This involves assessing the design and manufacturing processes to determine their compliance with specified or general requirements, based on professional judgment.

Inspections for printed circuit boards can be customized to meet the specific requirements of each client. Timely and professional inspections play a crucial role in identifying defects prior to electrical testing and gathering data for Statistical Process Control (SPC).

Given the widespread use of Surface Mount Technology (SMT) in PCB assembly, inspections become even more vital due to the increased stress that SMT solder joints must endure compared to those using Plated-Through-Hole (PTH) technology. As SMT devices rely on the structural integrity of solder joints to remain securely attached to the board, conducting thorough inspections is paramount to ensuring the long-term electrical reliability of circuit boards.
