What are the auxiliary products of PCBA conformal coating spray processing?
1. Thinner
- Under normal circumstances, the concentration of the use of conformal coating is impossible to require 100%, so sometimes we need to dilute it, the common dilution ratio in the industry is 1 part diluent, 2 parts of conformal coating, it is worth noting that when the dilution of the three anti-paint, we must wait for the bubble to disappear before it can be used again.
2. Film covering agent
For some parts of the circuit board that can not be coated with conformal coating spray processing, you can use cover treatment, this time, is the product of the film layer cover agent to show its skill.
3. Silicone glue
On the circuit board, some parts need to have high impedance and high voltage, which will seriously affect the safety of the use of the circuit board, so it needs to be closed, silicone glue has excellent effects in this field.
4. Film remover
In the process of conformal coating spraying, it is inevitable that you will encounter a laminating error, or replace conformal coating and other circumstances, at this time, you need film remover to remove the original film layer!
