Printed Circuit Board (PCB) consists of a thin, flat sheet of insulation on which electrically-conductive patterns are printed or engraved. These conductive patterns, made of copper or other conductive materials. Printed Circuit Board Assembly (PCBA) is the ultimate outcome of the manufacturing process of electronic items.

Aluminum PCB PCB aluminum-based copper plate is a metal circuit board material, consisting of copper foil, thermal conductivity insulation layer and metal substrate. Its structure is divided into three layers:Circuit layer: equivalent to the copper cover plate of ordinary PCB.

Automated Optical Inspection (AOI) is a machine-based technique used to test and evaluate PCB boards for potential faults like surface defects, dimensional defects, and component placement defects. As circuits become more complex, it has become almost impossible to manually inspect the boards and

Using a PCB Stencil to apply solder paste makes the pcb assembly process faster. It also makes it easier to apply solder paste accurately.
