Subject: [TN] Liquid Masking Deposition Process

Hello all,

Just like many of you out there I am in the position of putting much
labor into a non-value add process such as applying liquid mask to
protect areas of a board from being soldered. I'm sure someone within
these walls has come up with a good economical solution to this problem.
This may be in the form of a 'cheap conveyorized robotic application
system; an inline curing system; possibly a UV masking material to
reduce cure time while still maintain cured integrity of the material;
etc... The problem for us is that we need to apply masking as a bare
board and after components are loaded. The bare board to protect
locations from being soldered and the loaded board to hold down
components during flow soldering. This very manual process is highly
variable and comsumes much time, thus the reason to look for ways to
improve this process. At the same time reduce labor and increase
repeatability, it would be also very beneficial to reduce the amount of
soils placed in our aqueous washers that would be perfect. Not asking
for much.

Thanks in advance. Any help welcomed and appreciated.

Chris
