UV curable solder resist ink
Color: Green,White,Bule,Red,Black,which color you
need,pls leave massage to me
Description:
-
UV light-sensitive green oil with a fast curing characteristics.
-
The PCB solder mask to protect the paint, repair the indispensable good helper.
-
Coating evenly, cover a transparent film, and then covered with a printed good pad Films, with plexiglass compression, sun, dry, light to remove the organic solvent to wash the ink pad, and then the sun , OK
-
UV light-cured solder resist ink, over the net performance, fast curing, strong adhesion, chemical resistance and insulation, single-sided circuit board solder with.

Note: The full mixing prior to use
Special Note: The use of this ink can not be diluted
2 The main advantage
1. Traditional printing,simple process, direct high temperature curing after printing, no need for exposure and development process.
2. It has good heat resistance, chemical resistance, wear resistance, the hardness can get to 5H.
3. This product is environmentally friendly and has passed the highest environmental standards in the EU.
3 Working procedure
1. Mixing
Stir the ink for 15 minutes and remain for 15-20 minutes,allow the ink viscosity to stabilize before printing begins(If adding viscosity, add 1%-2% of appropriate diluent , it is recommended to use anti-white water BCS diluent).
2. Pre-treatment
Chemical treatment or physical treatment , to ensure that the surface is clean and dry.
3.Printing
3.1 Screen mesh: 51T–100T.
3.2 Scraper: 60-75 degrees; Note: The scraper requires no gap, sharp and flat.
3.3 Printing thickness: 10-20um.
3.4 Note: If you stop printing for more than 15 minutes,you must print a few sheets of dust-proof paper and silk screen film before restarting printing.Due to the increase in the viscosity of the ink on the printing screen,uneven ink is generated.
3.5 Post cure
Hot air circulation oven;
1. Pre-baking, 150 ℃± 5 ℃,5-10minutes.
2. After baking, 150 ℃± 5 ℃,25-40 minutes.
Tunnel furnace:200℃~220℃.
Speed, plate thickness 0.8~1.2, 2~3minutes.
Speed, plate thickness 1.2~1.5, 3~4minutes.
4 Attention
1.The ink contains solvent, and the workplace should be well ventilated.The room temperature should be maintained at 25℃± 3℃.
2.The ink needs to be printed within 7 hours.
3.In case of accidental contact with the skin or eyes, rinse immediately with soap and plenty of water. Do not use any solvents.
4.The above parameters are for reference only, the specific operation is subject to the sample.
