Capacitive Discharge Projection Welding System 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. TYPICAL APPLICATIONS • 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 analyzers and moisture monitors for integrated process control. • “Weld fire” lockout monitors the capacitor bank charge and prevents firing if the energy level differs from the set point, ensuring repeatable weld pulses. • Efficient stored energy design provides stable, consistent output pulses which are not affected by AC input power fluctuations. • Single Phase AC Power HERM ETIC SEALING Pulsar Series
