The technology designs a modular friction stir welding tool holder. This welding tool holder integrates a variety of functions, including constant pressure welding, temperature monitoring, removable FSW tool design,can be clamped to an existing CNCmachine. The advantage is that it can realize the function of automatic exchange for friction stir weldingCNC milling in one machine. Breaking through the previous friction stir welding, you need to buy a friction stir welding machine, which is expensive to obtain.

This probing equipment is integrated by the opto-mechanical, electricalvacuum systematic technologies to efficiently measure the electric properties of gas sensor chips at wafer level. Therefore, we can identify the functionality of each sensor chip in early phasethen discard the unqualified chips to enhance the production efficiencyproducts competition.
