Uses of CIT Manufactured Parts
Welded parts manufactured at CIT have wide uses. These include diode leads, lamp leads, resistor elements, and tantalum capacitors.
These parts are packaged in various ways such as round vials, square vials, and different size boxes. With the exception of box packaging, the welder will typically have automatic counting and packaging.
Quality of welded components is controlled by the use of statistical process control (SPC) during manufacture of parts. This process is then checked doubly by a final inspection.
To implement this quality control requires the use of various test instruments and computer testing instruments, including digital micrometers, digital comparators, digital pull testers, digital OHM meters, and computer-controlled part handlers.
All of this equipment is integrated into a complete system via a PC computer network which allows access to process data at any time.
CIT Innovations
Compaction of Low Density Tantalum Anodes for Increased Weld Strength
A capacitor manufacturer discovered that its in-house welding of low density tantalum was creating low weld strengths. CIT engineered a completely new pellet feeding welding system which solved the problem.

Resistance and Percussive
Arc Welding in Diodes, Capacitors, and Power Rectifiers
Resistance and percussive arc welding are the most commonly used methods for joining of metals used in the U.S. electronic component industry, and have the following applications:
- Dumet to CCFE for use in the manufacture of diodes;
- Pressed and Sintered Tantalum to Tantalum Wire for use in the fabrication of capacitors;
- Molybdenum to zirconium copper for use in power rectifiers;
- Nickel Wire to Tantalum Anode Riser Wire for use in capacitors.
