Photo etching has the flexibility and precision required to produce ultra-fine pitch, high pin count lead frames more cost effectively than conventional stamping technology.
Whilst EMI/RFI shielding can be manufactured in a variety of ways, photo etching offers distinct advantages, improving functionality and lowering cost.
Semiconductor cooling plates
Complex channels and geometries can be photo etched onto individual cooling plates economically, maximising thermal efficiency.
Flat, burr-free squeegee blades can be photo etched to ±0.025mm accuracy. Subsequent in-house electropolishing is available for a smoother surface finish.
Connectors and contacts
2-D and 3-D connectors and contacts can be photo etched from virtually any metal and post-process coated to improve wear resistance and enhance conductivity.
Shims, gaskets and washers
Photo etched shims, gaskets and washers are accurate to ±0.025mm, flat and burr-free, with no rough edges that could interfere with other mating components.
Springs, flexures and diaphragms
Photo etching ensures burr and stress-free springs can be manufactured with zero distortion or surface imperfections.

Miniaturisation, speed and economy
As the demand for electronics grows, increased competition is driving down the cost of manufacture.
To remain competitive, designers are looking to produce smaller, higher precision parts, pushing the limits of traditional metal machining techniques.
Through our market-leading photochemical etching service, we are uniquely placed to meet the industry’s trend towards miniaturisation, speed and economy.
Low-cost, fast digital tooling
Using digital and easily re-iterated tooling, rather than expensive and time-consuming steel tools, photo etching fits the low-risk product development strategy adopted by many electronics manufacturers.
Our costs do not increase with part complexity
We machine component features simultaneously, which allows designers to focus on optimised part functionality rather than cost.
Economical, versatile volume supply
Precision Micro has the resources to compete on a global scale, and the capability to meet world-class levels of product quality, productivity, competitiveness and continuous improvement.
In addition to our chemical etching service, we offer a variety of in-house and subcontract forming and finishing processes to help streamline supply.
- Hard and hand forming
- Spot welding
- Brazing and diffusion bonding
