Custom Packaging
 Semelab - Your First Choice
  • Semelab are experts in semiconductor packaging
  • We are able to mount a vast range of die into available package types, subject only to size and thermal considerations. In addition we specialise in the design and manufacture of complete circuits and device arrays for small signal, medium power and high power applications.

Modified Modern Packages
We can supply modified TO257, TO254, TO258 and TO267 packages as follows:
  • Mounting options - Z-tab or no tab
  • Pin options - flexible copper pins
  • Pin diameter options
  • Seal material options
  • Modern Package Types

Lead Pre-Form and Cropping
We can supply TO257 and TO254 packages with leads cropped and formed.
  • Standard 'hard' leads formed to shape and length
  • Undertaken to customer drawings (after review by Semelab)
  • Flexible lead options are available on modern metal packages, and offer an alternative approach to forming with particular advantages
