The main factors affecting the quality of solder paste printing The first is the quality of the stencil: the thickness of the stencil and the size of the opening determine the printing quality of the solder paste. Too much solder paste will cause bridging, and too little solder paste will cause insufficient solder paste or … Continued
In PCBA processing, two common soldering methods are reflow soldering and wave soldering. So in PCBA processing, what is the role of reflow soldering, what is the role of wave soldering, and what is the difference between them? PCBA refers to the abbreviation of Printed Circuit Board + Assembly, that is to say, the bare … Continued
Benefits of using patch components The patch element has a number of advantages over the lead element. On the first hand: small size, light weight, easy to save and mail. For example, the commonly used patch resistor 0805 package or 0603 package is much smaller than the direct resistor we used before. A few dozen … Continued
一. Welding process The so-called welding, is to use solder as a medium, that is, heating and making the two metals connected and achieve the purpose of conducting electricity. 1.Good welding basic conditions: (1)Welding parts must have good weldability. (2)The surface of the welding parts must be kept clean. (3)Suitable flux is necessary. (4)Welding parts should … Continued
