In the production process of SMT small batch chip processing plants, some circuit boards or components need to be manually soldered for some reasons. SMT chip processing is a very important part of the electronic processing and production process. If it is manual soldering, Only by achieving the same effect as the placement machine can…
In the SMT patch proofing process of the SMT small-batch patch processing plant, a white spot or white spot will appear on some circuit boards. What is going on? The appearance inspection also accounts for a large part of the quality inspection of electronic processing. The circuit board with white spots is obviously unqualified. So…
With the continuous development of the electronics industry, the technical level of PCB boards is also constantly improving. Common processes mainly include tin spraying, immersion gold, gold plating, OSP, etc. In fact, tin spraying is divided into lead-free tin spraying and lead spraying tin, so what is the difference between them? 1. From the surface…
The biggest problem encountered in the maintenance of electronic products is the short circuit. The short circuit on the PCB is quite harmful, ranging from burned components to large PCB scraps. Therefore, in PCB proofing, we must master every production detail and try to avoid short circuits. 1. If it is manual soldering, visually inspect…
