Unitek Miyachi - Projection Welding - Miyachi - #1

Capacitive Discharge Welding Systems

• Short duration weld pulse enables low energy welding and repeatable precise results

• Ultra-fast rise times for high throughput weld cycles over a broad range of applications

• High value price/performance ratio

• Simple intuitive user interface

The Pulsar power supply and high-efficiency matched weld transformers can be combined with a KN Weld Head for single station production or a RP3000 Rotary System for high volume production. Production proven in industrial environments around the world, these systems are dependable workhorses of the industry. Whether hermetically sealing microelectronic packages or joining a variety of metal parts, Pulsar's broad range of precision power choices provide technically advanced process solutions. The Pulsar Series can be easily integrated into atmospheric enclosures to insure high yield hermetic sealing results.

•Accommodates a variety of metal joining requirements, including sensors, frequency devices, filaments, heating elements, photonics packages, strain gauges, transducers, and more.

• The solid state weld controller produces an adjustable series of steps that initiate weld firing.

• Pulsar capacitive discharge power supplies are the most efficient available, configured in a variety of models, from 200 - 9000 joules.

• Weld energy is discharged to the part only after proper charge is verified. This ensures a consistent weld pulse.

• A weld inhibit function accepts input from atmospheric enclosure instruments, such as oxygen analyzer and moisture monitors, for integrated process control.

• All systems have been extensively field proven, producing millions of welds.

• Designed to operate as either manual or automatic welding equipment, or can be retrofitted to an existing welding system.

• Unitek Benchmark's low input power requirement guarantees weld stability and a weld pulse of short duration and concentrated high energy. Output weld energy is discharged from capacitor storage banks which are independent of the main AC power input. A Unitek Benchmark system requires only 3.5-50 amperes, compared to AC power systems requiring 100-800 amperes.

• Hermetically seals diverse microelectronic packages, ranging from the smallest TO, UM and HC styles to hybrids up to nine linear inches (230mm), depending on package design.

• Pulsar's short, high energy weld pulse, localizes heat in the weld zone, reducing heat build-up in sensitive micro-electronic packages.
