Hermetic Projection Welding System
Pulsar
Product Description
The Pulsar Series capacitor discharge welding power supplies, combined with model KN-II weld heads provide dependable, field proven system solutions for hermetic sealing of microelectronic packages and joining of a variety of metal parts. The Pulsar Series offers a broad range of precision power choices and can be easily integrated into atmospheric enclosures to ensure high yield hermetic sealing results
Key Features
- Capacitor discharge (CD) technology supplies short, high energy welding pulses which localize heat in the weld zone, reducing heat build-up in sensitive microelectronic packages.
- Wide range of models offer from 1000-9000 joules of energy
- Hermetically seal diverse packages ranging from the smallest TO, UM and HC styles to hybrids up to 5 linear inches (127 mm) depending on package design
- “Weld inhibit” function accepts input from atmospheric enclosure instruments, such as oxygen analysers and moisture monitors for integrated process control
- All weld parameters are accessed, set, and displayed on the front panel of the SS-1 Weld Head Controller
- KN-II Weld Head provides fast follow-up allowing for complete metal fusion without weld splatter
- Custom designed electrodes and holders are available to suit your application
