Photoresist Boards

Photoresist boards are light-sensitive material sheets, made from high quality glass epoxy with a copper foil bonded to one or both sides. They are essential for producing and prototyping printed circuit boards PCBs

What are photoresist boards used for?

Photoresist boards support PCBs which connect electronic components in many electrical devices. Printed circuit boards are manufactured using a pattern process which is defined during electro plating, using photo resist technology.

How do photoresist boards work?

Photoresist boards block ultraviolet light (UV) and fluorescence through presensitised boards. This is achieved by exposing the resist-coated boards to UV light before they're developed. When exposed to the light the polymers become more soluble. Panels on a PCB pass through a vacuum chamber where the layer of positive photoresist is then pressed firmly onto the surface of the foil. The printed circuit pattern is positioned on top of the photoresist and the panels are exposed to an intense UV light. Etching is then undertaken to remove the copper-clad substrate.
