Photochemical Etching for Extreme


Applications Precision Micro Produces Flexure for Tales Cryogenics


BONNY VAN GEEL, TECHNICAL SALES MANAGER, PRECISION MICRO


When manufacturing parts for critical applications, it is vital that the process chosen is not only cost-effective and allows adherence to time-to-market objectives, but is also able to adhere to extremely tight tolerances and produces accurate parts in volume with minimal wastage. Photochemical etching company Precision Micro was chosen by Tales Cryogenics — one of the world’s largest suppliers of electronic devices and equipment — for such an exacting manufacturing challenge, the production of flexures to be used for a cryogenic cooler in a satellite. Tis article looks at the nature of the photochemical etching process, and why it is oſten chosen by manufacturers of precision metal parts due to its ability to produce feature-rich, complex parts while retaining material integrity. Te specifics of the process by which Precision Micro produced the flexures for Tales’ satellite cryogenic cooler are used to illuminate the nature of photochemical etching and its applicability across a wide range of industrial applications.
