Benefits of Bronze Photo Etching

Versatile

The process of phosphor bronze photo etching is one which can be used for many different products across a full range of sectors and industries.

Best Quality

Phosphor bronze is ideal for metal components where accuracy and precision are vital in it’s application, as the etching process produces, burr-free and stress free components to the highest standards.

Dedicated Team

From start to finish, we are continually putting our customer’s needs first, individualising every step of the process to enable us to tailor the end result to each client’s specific requirements.

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.

1
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.

2
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.

3
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.

4
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.

5
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.

6
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.

7
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.

8
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.

9
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.
