Solder Mask and Milling
Beside
our green solder mask line, a second air spray machine is
available to deposit colored solder masks: with three
different guns and three separated hydraulic circuits , this
equipment allows us to spray colored solder mask (white,
black, red, blue, yellow …) without interfering with the
normal production (mainly green). Thanks to a recently
installed milling machine, it is now possible to mill PCBs
with automatic alignment driven by a CCD camera: this way
FIMA guarantees to satisfy tightest dimensional tolerances.
This equipment makes it also possible to carry out Z-axis
controlled counterbores with a still unbeaten precision of
+/-10 μm.
Electrical Test
FIMA is
equipped with two universal, bed of nails, electrical
testers and two flying probe testers. Therefore it is
possible to electrically test printed circuits under any
test parameters required by the customer (in certain cases
up to 500 V). The sorting of the “good” and “bad” PCBs after
testing is fully automatic which totally eliminates human
errors. In addition, impedance values can also be measured
upon request and test coupons are available for proof. A
measuring report is also provided.
