After using these mobile devices thoroughly, the researchers successfully paired them into final recyclables, resulting in more environmentally friendly devices in electronics manufacturing. Likewise, with the advent of soluble PCB Assemblies, there has been rapid innovation in the medical world. Medical research…
Corresponding inspections are required before and after the complete PCBA processing is completed. So, how to effectively inspect after SMT chip processing? 1. Check the layout of the pcb module board for foreign matter residues, PCB scratches, and other undesirable phenomena. 2. The inspection direction is moved from left to right and from top to…
Many newbies will determine the quality of the quality based on the color of the scrap circuit board. So, what effect does the color of the PCB circuit board have on performance? In fact, the color of the PCB circuit board does not have a great relationship with the performance of the PCB. The color…
Among the poor welding of SMT, cold welding occurs less frequently, but is extremely harmful, because it affects the long-term stability of the product, and often occurs in the hands of customers with electrical connection problems. The phenomenon of SMT cold welding is mainly manifested as cracks or gaps on the surface or inside of…
The main PCBA Manufacturing Pollution mainly includes the following aspects: 1. PCBA surface pollution will be caused by the pollution or oxidation of PCBA components and PCB circuit boards; 2. Fingerprints will be produced during manual soldering, and some wave soldering claw marks and soldering pallet (jig) marks will be produced during wave soldering. There…
Why PCB Circuit Boards are Widely Used in Electronic Products? 1. High reliability: We will pass a series of inspections, tests, and aging tests to ensure long-term reliable operation of the electric board circuit. 2. High density: For decades, with the improvement of integrated circuit integration and the advancement of mounting technology, high-density printed circuit…
In the process of making PCB circuit boards, PCB board inks play the role of protecting the copper foil, so that the copper skin is not exposed to the outside, thus affecting the subsequent processes; the commonly used ink colors are white oil, green oil, black oil, blue oil, red oil, butter. So, what are…
