A Process to Measure the Resolution Capabilities of PCB Imaging Equipment
1be use oCne\’ imaging equipment in
conjunction with older machines can cause
confusion within the imaging department
regarding the firm’s ability to resolve fine lines.
Obviously. newer equipment can perform better
than older, vintage equipment. 1be answer to
the problem has generally been to junk old
equipment and–at great cxpensc–purchase
newer models. Keeping the older machines
requires that artwork generated is designed to
conform to the lesser and older-performing
imaging machines. The problem we faced at
Chemart is that we purchased a Calight 1600 but
continued to usc the older ORC 201 B and the
Calight DMVL930. lbcsc machines were
technologically at least 10 to15 years old.
