Operating parameters
1.Substrate surface pretreatment
With 3-5% sulfuic acid water cleaning ,grinding brush wheels were 500,800,1000 mesh,1200 mesh,the drying temperature is 80DEG-120DEG 10mm-20mm,grinding mill,require time is more than 20s.
2.Open oil
Will be fully mixed with the ink after mixing,stirring after the completion of static 15min or more,so that the ink viscosity stability in the use of.
3.Screen printing
Screen printing:take 100-120T nylon diagonal net tension 23+1N
Squeegee angle of 5-20 degrees2-6kg/cm-pressure
4.Dry
Room temperature 2H or 70-90C for 10-15min
Note:According to actual temperature and humidity of the environment,there is a big difference in the drying time ,but shoube be completely cured ink.
5.Etching
Acid(or Alkaline)etching solution:temperature 40-10DEG C,the proportion of 24-28Be,55-60s,2.5-3.0kg/cm(20Z copper 120-150s)-pressure.
6.Ink removal
40+10C,3-5% NaOH solution,20-40s,spray pressure-1.5-2.0kg/cm
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,paractical application to customers for the field test conditions and test results.
