Polarity components require special attention throughout the PCBA processing, as incorrect orientation can lead to mass failures and the complete failure of the PCBA board. Therefore, it is crucial for engineering and production personnel to understand SMT polarity components. 1. Definition of Polarity Polarity refers to the positive and negative terminals of a component or … Read more
In the SMT (Surface Mount Technology) production line, the birth of each circuit board is a game of precision and efficiency. From solder paste printing to component placement, and then to soldering and curing, even the slightest flaw in any link can trigger a “butterfly effect”—leading to unstable product performance at best, or mass rework … Read more
When it comes to circuit boards, many people should be familiar with them, as they are ubiquitous in our lives, from small devices like Bluetooth headsets, electronic watches, and calculators to larger systems like computers, communication devices, and military/aerospace systems. Wherever integrated circuits are needed, they rely on PCB to carry electronic components. Before PCB … Read more
How are circuit boards made? The production process of PCB boards can be roughly divided into: Printed circuit board—inner layer circuitry—lamination—drilling—plating through holes (first copper)—outer layer circuitry (second copper)—solder mask green paint—text printing—contact processing—shaping and cutting—final inspection and packaging. So there are many devices involved; what equipment does PCB need? Generally, the production of PCB … Read more
