PCB is a printed circuit board, also known as a printed circuit board, is one of the important electronic components. However, PCB foam problem in the production and processing process often needs to be solved. In view of this problem, PCB defoaming agent is used to solve it.
PCB defoaming agent is mainly made of special modified silicone polyether as the main material. PCB defoaming agent has excellent defoolding and suppression properties. For PCB foam, it can play a good role and does not affect the circuit board material. The defoaming agent has high electrolyte resistance and good thermal stability.
For PCB foam problems, such as: the foam residue in the cleaning process, the foam in the membrane regression process and the foam in adding chemical additives in the cleaning process can be solved.
Use method of PCB defoaming agent:
1. It can be added to the cleaning agent and then added to the PCB for cleaning.
2. Dilute the defoaming agent first, and then sprinkle to the foaming site for defoaming.
3. Or add it directly with a low concentration of defoaming agent.
PCB defoagent: 0.1% -0.8%
PCB defoaming agent storage conditions: light sealing and sealing, used up within the specified period.
