USAGE:
Clean the board with acetone. The board should be cleaned completely.
Remove the tick layer from the Dynamask foil. (use two pieces of Scotch tape)
Laminate in a HOT laminator. (Switch the laminator to the hottest position and wait 10 minutes)
The Dynamask foil should never overlap board! (Otherwise your laminator rollers will be break and you have to clean them)
Laminate exactly like above
video (on YouTube)
shows
.
Dynamask and board should meet each other at the laminating rollers. (in order to avoid any air bubbles)
Press the board about 4 times through the laminator
and cool immediately, under cold water to get a good adhesion.
Expose (approx. 45 sec. at 4x15 watt UV) with the Solder Stop layer. (General rule in this is that you take half time of the time for exposing your PCB. So, if you need 180 seconds for exposing time for your PCB, than  for Dynamask it would be 90 seconds)
Lay down the board one hour in a dark place.
This is an important step!
Remove the seccond layer from the Dynamask foil. (use Scotch tape)
Develop in 1 liter water and 10 grams developer at 45 degrees celsius.
Use a soft acrylic brush for developing. Gently rub the board.
If things haven’t worked out OK completely, you can just leave the board in the developer. After a few hours, the Dynamask foil  will be completely dissolved and you can start all over again. In this case you need to
make
new developer.
After developing do not touch the Dynamask foil.
Rinse with water and let the board dry.
30 minutes to harden under UV light
Keep this Dynamask foil in the shipping box or envelop and store in a cool and dark place.
