PCBA Processing

The PCBA processing technology is very complex, and it basically has to go through nearly dozens of processes, from the circuit board manufacturing process, component procurement and inspection, SMT patch assembly, DIP plug-in, PCBA testing, program firing, packaging and other important processes. Among them, the circuit board manufacturing process is the most, and the procedure is extremely complicated.

Circuit board processing technology and equipment

Circuit board equipment includes electroplating line, immersion copper line, DES line, SES line, cleaning machine, OSP line, immersion nickel gold line, press, exposure machine, oven, AOI, board warping leveling machine, edge grinding machine, cutting machine machine, vacuum packaging machine, gong machine, drilling rig, air compressor, tin spraying machine, CMI series, photoplotter, etc.

SMT chip processing technology

◆ According to the customer's Gerber file and BOM, make the process file of SMT production, and generate the SMT coordinate file

◆ Check whether all production materials are ready, make a complete set of orders, and confirm the production PMC plan

◆ Carry out SMT programming, and make the first board to check to ensure that it is correct

◆ According to SMT process, make laser steel mesh

◆ Carry out solder paste printing to ensure that the solder paste after printing is uniform, with good thickness and consistency

◆ Mount the components on the circuit board through the SMT placement machine, and perform online AOI automatic optical inspection if necessary

◆ Set a perfect reflow oven temperature curve, let the circuit board flow through reflow soldering, and the solder paste will be transformed from paste, liquid to solid state, and good soldering can be achieved after cooling

◆ After necessary IPQC inspection

◆ The DIP plug-in process passes the plug-in material through the circuit board, and then flows through wave soldering for soldering

◆ Necessary post-furnace processes, such as foot cutting, post-welding, board cleaning, etc.

◆ QA conducts comprehensive testing to ensure the quality is OK
