Photo plotting
Our
standard form of communication with the PCB fab houses is Gerber-format
photoplot files. These files direct an "aperture" to
paint a pattern on a piece of "film". Of course, with
today's high tech tools it may be the case that the "aperture"
is really a computer controlled laser, and the "film"
may or may not really exist... But that is not our concern. What
matters is that the photoplot files be generated properly, and
that they contain all-and-only good information. Remember: you
will be paying for what you get, and you will get what your photoplots
ask for.
We
plot all our files on Konica PCB-7/ KODAK ACCUMAX (.007"
thick) which is currently the best the industry has to offer.
Our
film is plotted in a clean room environment (temperature &
humidity controlled) and is carefully inspected before shipping
by our experienced technicians.
We
supply Master Phototools in airtight plastic bags to prevent moisture
ingress when shipped. The Phototools are packed in cardboard for
insulation.
Examining
the Photoplotting films
Inspection of general quality of film like film thickness, developing
quality, image sharpness and opaqueness, scratches, dusts, foreign
materials, pin holes etc.
Track width and spacing measurement with respect to the
specification data sheet.
