Pcba Electronic Board Assembly

Pcba Electronic Board Assembly

Pcba Electronic Board Assembly is a board obtained after all printed solder paste on the PCB is then mounted with various components (such as resistors, integrated circuits), capacitors and any other components (such as transformers), depending on the application and circuit The required characteristics of the board. PCBA typically undergoes reflow oven heating to establish a mechanical connection between the PCB and the component.

How to assemble a circuit board

Board assembly is a process used in the electronics industry to solder or insert various electronic components, integrated circuits, etc. into a blank circuit board for quality inspection and testing to ensure complete circuit connections.

Blank boards are manufactured based on customer PCB files (gerber) and bom tables. Therefore, there are no electronic components on the whiteboard, only a variety of pads. After the installation is completed, the plug is installed, ie SMT, that is, the electronic parts are soldered to the pads, and then the DIP plug-in is required for processing to complete the entire soldering process.
