Thermo-compression Bonding

Thermo-compression Bonding

Thermocompression Spot Welders

Sunstone’s micro welding solutions are perfect for micro joining and thermocompression bonding. When bonding small wires (1-3 mil diameters) from one connection pad to another, Sunstone’s dual pulse welders and micro weld heads are recommended as the optimal setup for thermocompression bonding applications.

In the past, thermocompression bonding processes yielded a large number of failures caused by weak wire bonds. Sunstone’s high-tech products provide a guaranteed solution for improving thermocompression bonding processes by providing reliable bonds and repeatable manufacturing processes.

  • Linear DC

    The Sunstone Linear DC welder is a completely unique resistance welding system with closed-loop feedback. Utilizing new patent pending technologies, the Linear DC welder has the power of a High-Frequency Inverter and the precision of a Linear DC. As mentioned, this is a completely unique product. It isn’t an HF welder since it does not require an external transformer, and it isn’t like typical Linear DC welders because it doesn’t use transistors to control the energy output. Yet, this product is able to perform the same functions as both of these technologies, and in most cases it has capabilities that exceed those of other HF or Linear DC welders – offering high repetition rates, fine low-energy control, and short or long weld times – without any of the drawbacks and inconveniences.
