Uv cured good adhesion good resistance to chemical and heat solder mask for pcb

Usage:
1. Mixing:

Mixed the mian ink ,stirring for 10-15 mins .

2. Treatment before printing:
1)Wash pcb with HCl or H2SO4 water solvent .
2)Brush the PCB with machine(300-500mesh) .If you do not have ,you could use brasive paper instead.
3) High press water cleaning ,then fresh water cleaning .
4)80 degrees temperature to dry pcb for few seconds.

3. Screen printing

Screen printing:120T or 250-300 meshes net for printing.

4. Curing

High press uv lamp for curing:
80W/cm*3 lamps ,energy request:1000-1200mJ
You could use the roll line for than and the speed of roll depends on the curing process and effect . The distance of lamps is about 8-10cm and lifetime of lamps is under 1000hours

Matters needing attention:

This specification in all parameters and results for the company's test data,can only be done for early reference,as a guarantee and basis,pratical application to customers for the field test conditions and test results.
