Latest Patents

One of his latest patents is the Magnetic Latch Transport Loader. This invention features a leadframe loader equipped with a magnetic latch of predefined strength that connects a drive arm mechanism and a pusher system. The design ensures that the force applied to a pusher blade is set below the threshold that could damage a leadframe. The magnetic latch is engineered to detach from the steel coupling structure when the force exceeds a preset value, preventing damage to the leadframe. The calculated values were validated through physical testing, ensuring a safety margin to release the magnet before any bending occurs.

Another significant patent is the Wire Bond Clamping Method. This method involves bonding wires by providing at least a first and second pair of bonding locations, with one of each pair subject to flexure when force is applied. A clamping force is applied to one of the bonding locations, allowing a wire bond to be formed. The clamping force is then removed, and a similar process is applied to the second bonding location. This innovative approach includes the use of multiple capillaries to perform bonding in predetermined directions, enhancing the overall bonding process.
