Sheet Metal Enclosures

Copper photo etching is often used to offer high electrical and thermal conductivity to metal components.

Through our Photo Chemical Etching process, the smallest and most complex designs are made possible such as electrical spring contacts, contact membranes, busbars, antennae and micro antennae, spring fingered contacts, heating elements and battery terminal as well as many other bespoke components to your own designs. The Copper retains all of its properties, as well as remaining burr and stress-free following our etching processes. At Qualitetch, we can offer your bespoke designs in a wide range of copper and Beryllium copper non-ferrous metal specifications and hardnesses as required.

Due to the high conductivity of Copper, the metal is often used for electrical, automotive and transmission components. One of its primary uses is for wiring and harnesses, especially within the automotive industry where many electrical components are manufactured from copper using the photo etching process.

The metal is cleaned once your design has been finalised, and the metal sheet covered with UV sensitive photo-resist before printing your design. The metal is then taken through a chemical bath with ferric chloride, which acid etches the design from the metal sheet to produce your finished precision components.

Any trace of UV photo-resist remaining is stripped and removed once the etching process has been completed − and your chemically etched metal parts are taken to our QA technicians for final dimensional approval.

At Qualitetch, we have found over the years that more and more customers are looking to rationalise their supplier base and find vendors that can offer all services needed under one roof, rather than losing valuable manufacturing time sending parts to several key suppliers to receive components.

Always on the front foot and pushing manufacturing techniques, Qualitetch have developed processes to ensure we can cope with these demands, and have created a specific cell team to deal with such requests and can offer necessary solutions. From Assembly, soldering, welding, spot-welding or bespoke packaging Qualitetch can offer a manufacturing solution for your needs.
