It is two component liquid thermal curable solder mask, which has such performance as good printing adaptability and fast curing rate. The cured film can provide good adhesion,heat and chemical.

 

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+/-20PS if printed by hand

180+/-20PS if printed by machine

200+/-20PS if it is alumium tamponade.

The viscosity of ink mixed above is measured at 25C.Please use the special diluent of our company if the viscosity of ink needs to adjust.

 

2. Remain time

10-15 minutes after stirring uniformly

 

3. Screen mesh

Ordinary boards:43T;Chemical-plating Aurum or Tin boards:36T

 

4. Pre-baking

1)Single side printing separately

   First side:72-76C,15-18minutes

   Second side:72-76C,30-35minutes

2)Double sides printing simultaneously:72-76C,40-60minutes

 

5. Exposure

300-500mJ/cm2,Black ink:600-750mJ/cm2(the effective value through the polyester film),exposure step:10-12 step(standard in the remained film)

 

6. Developing

Developing solution:0.8-1.2wt%Na2CO3 or K2CO3 aqueous solution

Developing solution temperature:28-32C

Spray pressure:1.5-2.5kg/cm2

Developing time:40-90 seconds

 

7. Post cure

Spray tin board:150C*(60-120)min

Chemical-plating Aurum board:150*(50-60)min

Thick copper plate,boards printed with black ink shoule be post-baked in subsection:75C+(60-120)min*30min+150C*(60-90)min

 

 

Attention :

  • The base and hardener should be mixed according to the ratio and stirred thoroughly before using.
  • We will offer you special diluent or DPM if the ink need dilute.
  • The values above are based on experiments in our lab. Experiments need to be carried out in order to get proper using condition.
