/The functions of resistance flux on printed circuit boards
The resistance flux is a high temperature resistant coating used in dip soldering and wave soldering in order to protect the parts that do not need to be welded during the welding process, so that the soldering operation is performed at a certain location. This material that acts to impede the welding action is called resistance flux.
What are the functions of resistance flux in printed circuit boards, which can prevent solder paste icicles, solder joint bridging connection, circuit board short circuit, virtual soldering and other defects, and improve the quality of PCB board welding . In the SMT welding process, all areas are protected except the welding pad need to be welded, at the same time save solder. The use of colored resistance flux can also make the surface of the soldered parts clean and beautiful. The use of resistance flux improves the quality of welding, ensures product reliability, and guarantees a variety of plastic components and integrated circuit
The resistance flux has a dry film type and a printing type , and the printing type resistance flux is further classified into a heat curing type and a light curing type, and light curing type resistance flux is widely used at present.
The above are the functions of resistance flux on printed circuit boards. For more information, please pay attention to this website www.cnfastpcb.com

① Standard components should pay attention to the dimensional tolerances of components from different manufacturers. Non-standard components must be designed in accordance with the actual size of the components and the land pattern and the space between the land. ② When designing high-reliability...
The water cleaning process of PCB circuit board uses water as the cleaning medium. A small amount (usually 2% to 10%) of surfactants, corrosion inhibitors and other chemicals can be added to the water. The PCBA cleaning process is completed by washing, washing and drying the source of pure water ...
