This is John Santa Cruz of Microchip Technology in Chandler, AZ. We have 2 AC Servo Drivers that are bad and was wondering if you repair them. They are used in the Accretech APM90A Wafer Prober for X/Y stage movement. The Drivers themselves are Tamagawa TBL Drivers. The Part number is AU6273N1031E35. Please let me know. Thank you.
