Conductive Metal Screening Powder Preparation

This powder sieving operation improves yield by eliminating metal particles from the paste that might otherwise clog the screening mask openings.

In the preparation of screening paste, a combination of conductive metal particles, a vehicle, and other ingredients are intimately mixed by milling under high pressure. It has been discovered that several metal particles can agglomerate and subsequently be molded and flattened by the milling process into objectionably large flake-like particles.

These particles are conveniently removed by sieving Mo powder before paste manufacture. The sieve size is selected to remove all particles that are above the largest size not deemed objectionable.
