Motor and Transformer Laminations: Custom, Prototype and Replacement
Complex designs are easily produced from inexpensive tools (about $265.)
The chemical etching process leaves no burrs and imparts no mechanical or thermal stress: annealing is not needed.
Microelectronics Packaging
Photo etching is the ideal solution for QFN and LD-MOS leadframes as well as a wide range of custom platforms.
QFN or “air-cavity” packages are widely used in RF and microwave communications applications due to the low attenuation loss. Complex and delicate leadframe designs are suited to the capabilities of chemical etching.
Flat and step lids for hermetically sealed electronics packages are readily produced by photochemical etching. Common alloys for these applications are in the nickel-iron family and include Kovar, Invar, F-15, and others.
Etched and Formed Enclosure for Electronic Assemblies
EMI/RFI Shielding
Electrically “noisy” products emit interference which must be contained by metal shielding in copper, beryllium copper, brass and others.
Chemical etching is a fast and economical means of producing both simple and complex enclosures and barriers to electromagnetic and radio frequency emissions.
Direct Bond Copper is a layer of copper vacuum bonded onto an alumina ceramic base with a circuit etched into the copper. Etched DBC parts are used in RF/microwave applications including cell phones, wireless and and microwave transmitters.
