Working procedure
1. Mixing
Mixing a small amount main agent with hardener and stirring thoroughly,then mixing the mixture above with the remanent main agent,add appropriate diluent and stirring 5-10 minutes. The viscosity of ink is adjusted to 120 PS if printed by hand. And it is adjusted to 180 PS if printed by machine.It is adjusted to 200 PS if it is aluminum tamponade .The viscosity of ink mixed above is measured at 25 degrees. Please use the special diluent of our company if the viscosity of ink needs to adjust.
10-15 minutes after stiring uniformly
1) Single side printing separately
First side:72-76 degrees,15-18 min
Second side:72-76 degrees,30-35 min
300-500mJ/cm2,Black ink:600-750mJ/cm2,exposure step:10-12 steps
Developing solution:0.8-1.2wt% Na2CO3 or K2CO3 aqueous solution
Developing solution temperature:28-32 degrees
Spray pressure:1.5-2.5kg/cm2
Developing time:40-90 seconds
Spray Tin board:150 degrees*(60-120min)
Chemical-plating Aurum board:150 degrees*(50-60min)
Thick copper plate,boards printed with black ink should be post-black in subsection:75 degrees*(60-120min)+100 degrees*30 min+150 degrees*(60-90min)
6 months since the date of manufacture,store below 25 degree in dark
1) Mixing the ink fully before using
2) We will offer you special diluent or PMA if the ink need dilute
3) The values above are based on experiments in our lab.Experiments need to be carried out in order to get proper using condition.
