As PCBs become more complex, patterns (pads and tracks) are
becoming finer and finer. It is very crucial to transfer the image
without any noticeable distortion. The finished image will act as a
plating resist. This is usually based on a dry-film resist of a
certain thickness that matches the plating thickness.
The most commonly used track width is about 0.102 mm (4 mils) which
could be regarded as the standard width. However, widths of 0.076
mm (3 mils) are also in use, and some Chinese PCB manufacturers
operate with track widths down to 0.050 mm (2 mils). But the PCB
designer should not be tempted by track widths of 0.076 mm (3 mils)
or smaller because the manufacturing yield becomes lower and the
board price, correspondingly, higher.
The purpose of image transfer is to cover those areas of the board
that are not to be plated with copper, tin/lead or pure tin, with a
plating resist, and to leave the pattern open for electroplating.
With plated-through-hole boards, image transfer is performed by
means of a photopolymer dry-film process consists of the following
