Precision Micro etches a wide range of custom 2-D and 3-D connectors and contacts including contact springs for military jets, contact membranes for home appliances, busbars for Formula 1 kinetic energy recovery, antennae and micro antennae for pocket-sized UAVs, spring finger contacts used in PCB applications and ultra-thin resistive heating elements used in electro-thermal ice protection systems.
Economical, precise and accurate
Unlike presswork, photo etching uses low-cost digital tooling, ensuring prototypes can be produced quickly and refined economically without expense. The process is accurate to ±0.025mm – the quarter of a diameter of a human hair!
Connectors and contacts often need to operate in extreme environment conditions, such as the human body, military jets or space satellites. Photo etched connectors are stress- and burr-free, ensuring reliability, and can be specified from high-performance metals which offer excellent strength-to-weight ratio, biocompatibility and low-coefficient of thermal expansion.
Forming and finishing
Our in-house press shop offers manual and semi-automatic precision forming using standard, modular and custom form tools. Where possible, bend lines can be incorporated into photo etched connectors, removing the need for hard form tooling.
Precision Micro also offers a range of post-process coatings to improve wear resistance and enhance conductivity, including gold, tin, silver, tin/lead and sulphur/nickel coatings, which can be full or selectively plated.
