SELF-DRY AND UV CURABLE ANTI ACID ETCHING AND PLATING RESIST INK
UV curing etching resist ink for acidic etching solution, which is used for making patterns on copper-clad laminates by means of acidic etching. The cured film can provide good adhesion, clear printing line, high resolution , resistance to the etching of acidic CuCl2/FeCl3 solution and fast removing coating.

Operating parameters
1. Pretreatment of substrate surface
With 3-5% sulfuric acid water cleaning,grinding brush wheels were 500,800,1000,1200 mesh,the drying temperature is 80DEG-120 DEG,brush marks 10mm-20mm,water grinding time is above 20s,pretreatment of absorbsent sponge roller cleaning once every 4 hours,prevention for long time adsorption roller oily impurities make the surface oil pollution.
2. Open oil
After ink is fully mixed to the mixing,stiring after the static 15min above ,so that the ink viscosity stability in the use of.
3. Screen printing
Screen printing:Take 100-120T nylon diagonal net tension 23_1N
Rubber scraper scraping:65-75 degrees of good elasticity ,sharp edges
Squeegee angle of 5-20 degrees,2-6kg/cm-pressure
Printing film thickness:12-18um
4. UV curing
Energy 800-1500mj/cm2
5. Etching
Acid or alkaline etching solution,the temperature of 45+5 C,the proportion of 24-28Be,50-60s,
20Z 120-150s,2.5-3.0kg/cm2 pressure.
6. Cleaning membrane
45+5C,3-5%NaOH solution,50-60s,spray pressure-1.5-2.0kg/cm2
