Copper Etching

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

Through our Photo Chemical Etching process, the smallest and most complex designs are made possible. The Copper retains all of its properties, as well as remaining burr and stress-free following our etching process. At Qualitetch, we can offer your bespoke designs in a wide range of copper and Beryllium copper non-ferrous metal specifications.


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 the design has been finalised, and the 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 precision components.

Any trace of UV photo-resist are then removed once the process has been completed – and the chemically etched parts then taken to our QA technicians for final approval.

Qualitetch offers a quick and efficient turnaround, even for the highest of demands, with a high level of accuracy and quality. If you would like more information on the photo chemical etching process of copper, please contact the team on 01354 658787.

Benefits of Copper Etching

Save time and money

Our assembly line approach reduces manufacturing time and allows us to save time by cutting unnecessary steps out of the manufacturing process.

Dedicated Team

We have a dedicated team of fully qualified professionals who are on hand to deal with and complete assembly work requests from our customers.

Bespoke Packaging

We offer assembly, soldering and spot welding, bespoke packaging, and also many other specialist bespoke customer requirements that our clients may have.

Photo Etching Process

The photo etching process produces metal components that are both stress-free and burr-free compared to more traditional manufacturing methods – ensuring that your end product is as both accurate and precise to your drawings.

Metal Selection

Qualitetch offer a huge range of metals for etching including: Stainless Steels, Carbon Spring Steels, Copper, Brass, Nickel Silver, Mild steel, Phosphor Bronze, Silver, Beryllium Copper, Aluminium, Nickel, Mu Metal, Alloy 42, Alloy 52 & Many Others.

Metal Cleaning Process

In order to ensure perfect parts every time, we need to clean the sheet metal to remove any impurities from the sheets surface before manufacturing your designs. This involves passing the metal sheets slowly through acid or alkaline solutions and rinsed prior to laminating, printing and developing.

Metal Cleaning

Metal cleaning involves passing the sheets slowly through conveyorised acid or alkaline solutions and rinsed clean prior to the lamination, printing and developing stages, depending on the sheet metal choice required.

Preparation - Lamination

Once cleaned the metal sheets are coated with a UV sensitive photo resist, which melts to sheet in preparation for the printing process.

Preparation - Printing

The printing process involves us taking your chosen profile design and applying it to a two sided top and bottom acetate photo film mask, that we then print your design onto the UV sensitive photo resist.

Preparation - Developing

Once the metal sheet is printed with your chosen design, we then need to develop the sheet. This process effectively washes away the fine lines of the profile we are cutting, leaving raw metal track lines ready for the etching process to work it's magic very precisely.

Photo Chemical Etching

The etching process itself is an acid, usually ferric chloride, that effectively eats it's way through the metal at a known rate to ensure precision and targeted only in the areas you wish to remove, such as the profile track lines or other holes and features such a mesh. The rest of the sheet is masked by the UV photo sensitive blue resist, to protect the metal from the etchant until the parts are complete. This can be a very useful in a manufacturing process as the design can be very complex or include tabs or half etch fold bend lines at no added cost as you simply print your design rather than needing expensive machining time. Following an on-line dimensional check, all that is then required, is for us to strip and remove the UV photo sensitive resist coating and the parts are ready for full QA Inspection.

QA Inspection

At Qualitetch we offer various levels of QA inspection depending on our customers needs, as we supply both major blue chip businesses all over the world as well as smaller local businesses and anywhere in-between, as the photo etching process is very versatile. We have various automated optical equipment to ensure you parts are accurately supplied to your drawings. We also offer levels of inspection including 100% inspection, PPAP levels, batch inspection, First article inspection (FAIR) and bespoke customer inspection as required.

Final Product

Once the parts are fully inspected and passed they are ready to be packed and sent to the customer, or for additional processes such as plating, forming, soldering, spot-welding, machining, EDM wire erosion, heat treatment or any other bespoke services required, such as assembly.
