H3TO

Research Quality: 40% complete

What is it?

The source identifies MRSI-H3TO as part of the MRSI-H family of flexible, high-speed, high-precision die bonders. It is specifically designed for handling multi-dies and multi-processes for complex TO products without tool changeover, and is shown in connection with wafer, waffle-pack, and Gel-Pak handling.
