An improved, simpler, less costly method of semiconductor mounting.
Avoid soldering directly to the semiconductor. Easier to service,
economical, more efficient.
ORDERING INFORMATION:
Complete Kits or Individual Hardware
Purchase the complete kit by catalog number as shown or individual
items in minimum 100 piece packages. Keystone does not supply
semiconductors.
