Solder Mask Finish Capability Data

Our liquid photoimageable solder mask, sometimes referred to as solder resist, is an ink-based liquid applied using a Electra EMP110 air spray, exposed in a sterile UV environment, then developed. It is a permanent layer that protects copper traces and their respective interfaces within a PCB, making it perfectly suited to most areas of PCB manufacture. Furthermore, this process helps prevent solder ball defects.

Our standard colour is green, but other colours such as black, blue, red and high white are available on request.

Our epoxy solder mask is a common two-part process for electronic applications. Screened onto the PCB pattern, epoxy liquid is the lowest cost type of solder mask. Epoxy is a thermosetting polymer, screened using a synthetic woven mesh to support ink-blocking patterns. The mesh creates open areas for ink transfer.

The final finishing process involves thermal curing.

For notation and serialisation, we use a Ink Jet printing process to mark up your Printed Circuit Board (PCB).

Our primary method is only available in white.

As an alternative the regular ink jet printing, we also offer thermally cured notation ink which allows us to use a range of colours for colour-coding purposes.

Many of the solder mask combinations can be supplied in a matt or semi-matt finish. The main difference is for aesthetics purposes only.

Our Printed Circuit Board’s standard colour is green, but multiple colours are available on request.
