“When considering the finish of the circuit board and what the quality of the coating is like we find customers perceptions and ours can vary. This is generally down to preconceived ideas of what a good quality coating should look like.”
“The standards state that when dipped a PCB can have coating dripping at a corner and have bubbles within. However, many customers don’t like this. The problem is that to reduce the dripping effect tends to have a knock on affect on the rest of the quality of the PCB like conformal coating thickness. So, educating the customer on what they should be inspecting and what is acceptable is key for the conformal coating inspection process”
