Electrical connectors and contacts are conductive metal bridges between two points to create a complete circuit. As the demand for smaller devices increase, so does the need for precision-made connectors and contacts.
We manufacture a wide range of custom 2-D and 3-D chemically etched custom electrical connectors and contacts, including contact springs, contact membranes, busbars, spring finger contacts and antennas.
Unlike presswork, our chemical etching service uses low-cost digital tooling, ensuring prototypes can be manufactured quickly and refined economically without the expense.
We can chemically etch micro electrical connectors to ±0.025mm accuracy as standard – a quarter of a diameter of a human hair!
What are our electronic connectors made from and why?
Our photo-etched electronic connectors can be specified from almost all high-performance metals – always offering excellent strength-to-weight ratio, biocompatibility and low coefficient of thermal expansion. We ensure reliability, as the chemical etching process leaves the components stress and burr-free.
Whether you need components in stainless steel, copper, nickel silver or brass, our process makes it possible.
Electrical contacts and connectors often need to operate in extreme environmental conditions, such as the human body, military jets or space satellites – so reliability is in the foreground of everything we produce.
Connector forming and finishing
Our in-house press shop offers manual and semi-automatic precision forming using a range of standard, modular and custom form tools.
Where possible, bend lines can be incorporated into etched connectors, removing the need for hard form tooling and offering you more freedom in design.
We also offer a range of post-process coatings to improve wear resistance and enhance conductivity, including gold, tin, silver, tin/lead and sulphur/nickel coatings.
Precision Micro is the company to trust for prototype, low and high-volume electrical contacts and connectors with exceptional precision, cost-effective production and short lead times.
We are market leaders in the production and development of chemical etching with long-standing partnerships with companies around the world. Get in touch with our team today to discuss your needs.
