Before introducing how to execute the function test after pcba processing, it is better to understand how it was executed in the past. The best way to know about the actual test is to visit the PCBA manufacturing plant that produces products

With the development of component packaging technology, most components can be purchased in packaging categories suitable for reflow, including plug-in components that can use through-hole reflow. If the design can achieve full surface mounting

Processing requirements for PCBA of circuit board:1. PCB edge widthThe board edge width is greater than 5mm, the panel spacing is less than 8mm, and the distance between the pad and the board edge is greater than 5mm.

SMD technology is different. The connection is made through the contacts at the bottom of the circuit board - metal terminals around the circuit board. Both technologies can be used on the same PCB for non SMD components, such as high power semiconduc

Many devices in the SMT chip processing production line are computer controlled automatic processing devices, which makes it possible to form a cad/cam integrated system by computer aided manufacturing.

Polychlorinated biphenyl proofing connector is a commonly used component in PCBA processing. Its function is very simple: establish a communication bridge between the blocked or isolated circuits in the circuit, so that the current can flow and the ci
