A) Function:
Coating of pcbs with photo imageable solder mask by pouring
method.
This method can
usually be applied with all photo inks available on the
market.
Pcbs pass the ink
curtain at a typical speed of 90 m/min.
The ink is
automatically pumped into the coating head from the supply
container .
A
microprocessor-aided viscosity control in the ink container ensures
a precise viscosity of the ink, by automatically adding solvents
and permanent temperature control.
The coating
head produces a vertically falling ink curtain. The pcbs are coated
in the desired layer thickness in an extremely homogeneous
way.
The coating
unit consists of:
Coating
head
Ink supply
tank
Solvent
tank
Pump
Viscosity
controller
Ink mixer
Normally the
coating unit is rigidly mounted – type LG.
Alternatively the
coating unit can be hold in rails – type LGW. It can be
completely moved out. If a second ink station is available, the
moved-out ink station can be replaced against a new one, freshly
filled up. The ink can be kept operational at a separate
location.
