hi
Happy new year.
Hope you are doing good.
We are trying to make our own PCB board.
We are using UV curable green soldemask ink .
We followed 2 methods to apply the solder mask
1) screen printing method
2) a method from youtube (
)
For screen printing, ween we tried to cure the solder mask for 4 hours under UV light and for our surprise, the ink did not even cure a bit.
In 2nd method, We got better results but when we tried soldering components, the hot air is creating air bubbles onto the mask.
Can you help us in knowing what is that we are doing wrong to not achieve a good solder mask on our board?
Thank-you
Warm Regards
