1. The base and hardener should be mixed according to the ratio and stirred thoroughly before using.2. We will offer you special diluent 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.Liquid photoimageable solder mask directions of use
1.Working procedure| Procedure | Content |
(1) Mixing
| Mixing about 30g main agent with hardener and stirring thoroughly,then mixing the mixture above with the remanent main agent and stirring 5 ~10 minutes. The viscosity of ink is adjusted to 120±20 ps if printed by hand. And it is adjusted to 160 ± 20 ps if printed by machine. The viscosity of ink mixed above is measured at 25 ºC .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 ~76ºC ,20 ~25min
Second side : 72 ~76ºC , 30 ~35min
2. Double sides printing simultaneously : 72 ~76ºC , 40 ~60min |
| (5) Exposure | 400~600mJ/cm2(the effective value through the polyester film), 10~12 step |
(6) Developing
| Developing solution :0.8 ~1.2wt%Na2CO3 or K2CO3 aqueous solution
Developing solution temperature :28 ~32ºC
Spray pressure:2.5~3.0kg/cm2
Developing time:60~90 seconds |
| (7) Post cure | Spray Tin board:150ºC×60~120 min;Chemical-plating Aurum or Tin board:150ºC×50~60 min;
boards filled with ink in the hole should be post-baked in
subsection:75ºC×60~120 min+100ºC×30 min+150ºC×60 min |
| 1. Requirements of working place :the temperature should be 20~24ºC and humidity is 55~65% in the room for printing and exposure without dust. Please work in the place without UV ray , or it will cause photo polymerization if the ink is used in the irradiation of white ray or sunlight. |
2. Mixing the main agent with hardener and stirring thoroughly and using only in
room temperature. |
3. Appropriate film thickness is from 18 to 22μm. Thinner film will reduce the
resistance to heat , chemicals and plating. Thicker film will cause excess under-cut and reduce the degree of dryness because the irradiation can not cure the botton layer of the ink. |
4. The screen boards can not be pasted with adhesion tape directly or else the
remanent mucus will cause hollow pot on board. |
5.The ink can not be printed into the accessory hole. Developing time should be
increased if ink gets into the accessory hole or there will be uncleaned. |
6. The condition and allowed range of pre-baking vary with the oven type and
different number of boards in the oven. Experiments need to be carried out to
get proper condition. |
| 7. Exposure energy varies with the board material and ink thinkness. Experiments should be carried out to determine the minimum width , surface gloss and the sensitization of the botton surface and then set proper condition. |
| 8.Inadequate developing temperature and time may cause unclean developing and over of them can cause excess under-cut and the feature of ink will be influenced because of the attack of ink surface. Please control the concentration of developing solution , temperature , pressure and developing time strictly. Experiments need to be carried out to get proper condition. |
9. The ink is easy to remove when the temperature and time of post-baking is
deficient. It will reduce the resistance to plating aurum and molten solder when the post-baking time is over 2.5 hours. Experiments need to be carried out to set
proper conditions of spraying tin and plating aurum. |
| 10. Experiment whether the ink can afford attack of the process of wave crest solder when the flux is rosin. |
11. Taphole boards are baked in subsection : 75ºC×60~120 min+100ºC×30
min+150×60 min. |
| 12. Please set proper post-baking tine of solder resist to suit for printing marking ink.Deficient or over hardening can reduce the feature of ink. |
13. Condition of chemical-plating aurum :
A. use 36T screen for printing.
B. The sensitization of exposure energy is 10 to 12 step.
C. Under-cut is controlled below 1 mil after developing or the film will easily be
attacked by the liquid medicine in the process of chemical-plating aurum.
D. The film need to cure through the UV bump again if the exposure is not
enough .
E. Chemical-plate aurum or tin first and then print marking ink. or excess
hardening will reduce the resistance to chemical properties. |
