LY-UVH900 UV CURABLE SOLDER MAST

Solder mask does not allow the solder to stick to it. It is why you can solder to a solder pad, but not to the board itself. It does not conduct electricity. LY-UVH900 is used to: Insulate jumpers. Cover exposed ground around BGA chipset pads. Cover leads of components you do not want to touch a jumper. It is heat resistant. Apply a small amount using a toothpick, then cure in with UV light. We also sell a UV "nail salon" style light to cure the green oil mask.
