Electrical and Electronic

     

Motor and transformer laminations:  

Custom, Prototype and Replacement

Typically produced from silicon steel alloys, also referred to as "electrical" steel or "M series" that have a surface finish called "coreplate" which creates a dielectric layer between laminations.

 

Photo etching is an ideal solution for small to mid-range (dozens to many thousands) quantities of motor and transfomer laminations. 

Complex designs are easily produced from inexpensive tools (about $250.) 

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.  These leadframes are typically very complex and delicate designs that are well suited to the capabilities of chemical etching.


 

 

EMI/RFI Shielding

Many electrically "noisy" products emit interference which must be contained by metal shielding.

Photo etching is a fast and economical means of producing both simple and complex enclosures and barriers to electromagnetic and radio frequency emissions.
