Responsible for the design of tooling and fixtures for the development, proving and production of wireless communication and related equipment. Designed automated fixture to align and assemble multiple components with cables attached, making assembly of product reliable and cost-effective. 5 years of factory use so far with no down-time. Created and patented unique method of aligning and compressing 2000 test probes with 350 pounds of force, while applying zero force to sensitive probe fingers in the same assembly. Test head was removable with no tools needed, and self-aligned for ease of use. Multiple antenna designes including manual and automated systems that could work reliably in all weather conditions throughout most of the world. Designed mechanical aspects of optical systems to test camera phones. Developed user friendly test equipment that needs no tools to operate or to change test samples. Designed rework fixtures to open phones with no damage or required tools. Many fixture designs using non-metalic materials for use in RF chambers.
Responsible for the design of major subassemblies for automated and manual test equipment for hard disk components. Also designed in-house tooling and created study models. Designed in-house life cycle tester to measure clamping for degradation in new tooling style. Tester operated 24 hours/day for two months, and exceeded 15 million load/unload cycles. Designed optical path for disk surface scan tester to include two light paths to test both sides simultaneously with one laser and one camera. Redesigned all mechanical assemblies for harmonic resonance tester. Improved repeatability, reliability and throughput.
Responsible for the design of mechanisms and major subassemblies for robotic computer chip handling equipment. Redesigned pick and place robotic loader and sorter. Increased performance, reliability and versatility. Designed set-up gages and fixtures reducing machine set-up time by three days. Increased accuracy and repeatability. Created universal latching mechanism to locate multiple sized chip trays in drawers. Interchangeable design avoided rework and scrap of entire machine, saving several hundred thousand dollars.
Responsible for mechanical design of sheet metal and injection molded plastic parts and assemblies. Created major modifications to existing injection molded assembly eliminating one part and three production stages with minimum tooling cost and no scrap. Designed enclosure for floor standing UPS battery backup product line. Built heat test model and performed thermal testing to aid design of new project.
