Sr. Field Service/Repair Engineer (2 openings)

Job Duties:
Responsible for repair of very high pin count (>30,000 pins) MEM's, vertical and cantilever probe cards (VPC and CPC). Replace PCB electrical components such as: Capacitors, resistors, special MUX IC. Adjust VPC space transformer flatness between MLO substrate and PCB by interposer connection. Evaluate customer feedback on probe card issue and take full card inspection to find the root cause. Provide technical support to customer’s new probe card verification on wafer sort and debug to identify setup issues, wafer product issues or program issues. Conduct training on new probe card and new technology application, including on-line clean and off-line maintenance. Contribute to probe card technical improvement to HQ production line. 30% domestic travel required (travel within US to customers’ sites for field service and repair support)

Job Requirements:
5 yrs. field service support and repair of high pin count (>30,000 pins) vertical probe card and cantilever probe card.
