Detail Information

Blue peelable mask layer is applied to:

1. Corrosion protection of various acid and alkali solutions;

2. Protection against electric corrosion of various electroplating solutions;

3. Various electroless plating protection.

Do not print blue glue under the following circumstances

1, surface treatment for tin, silver and other easy to be oxidized and easy to wipe the board, not printed blue glue.

Reason: this plate surface treatment process is easy to be oxidized, can not bake the plate, but after printing the blue glue must be through the baking plate to solidify the blue glue.

2, not double-sided printing blue glue.Reason:

A) double-sided blue glue enters the hole, and it is difficult to tear off the blue glue;

B) after printing one side, the blue glue bulges, causing uneven, inconvenient printing the other side, and easy to cause plate bending problems;

C) plate bending is not easy to measure.

Peelable mask pcb performance

1. No solvent volatilization, environmental protection and safety, almost 100% solid content, almost the same thickness of dry and wet film;

2. High thixotropy, effectively ensuring smooth screen printing edge, strong cover pore force and slight vertical flow;

3, good adhesion is not peeling off;

4. Easy to peel, complete, no residual flow, no impact on the bottom layer;

5, does not contain any metal and non-metal monomer, corrosion resistance process will not dissolve any material, no impact on the original solution. The pass hole is easy to be peeled off without residue and has no effect on the original solution.
