Shenzhen 1942 Technology Co., LTD is a one- stop service PCB manufacturer ,focus on PCBA used in Medical equipment, industrial control, IOT ,etc. We have 7 SMT line, we would like to share some key points about SMT and PCB and PCBA , hope it will be helpful.
Let’s talk about the cleaning technics of PCBs. During the SMT soldering process of PCBs, certain flux and impurities will remain on the surface. If the cleanliness of the PCB after soldering cannot be effectively guaranteed, the service life of the product may be affected, and even the normal operation of the PCB may be affected. Therefore , the cleaning process of PCBs is the necessary step when we produce PCBs. We would like to share some experience of the cleaning technics, welcome to discuss with us.#shenzhen 1942 Technology #SMT factory
1. When using water cleaning and semi water cleaning technics, a certain amount of emulsifier can be added to the water. When cleaning synthetic resin and other pollutants, these pollutants will emulsify with emulsifier and then dissolve in water. Adding surfactant can improve emulsification. #pcba #PCB cleaning
2. The cleaning agents used in the semi water cleaning process are organic solvents and deionized water, in which a certain amount of active agents and additives are added. This cleaning method is between solvent cleaning and water cleaning. These cleaners are organic solvents and flammable solvents, with high flash point and low toxicity. They are safe to use, but they must be washed with water and then dried in an oven.
