Expert has designed precision machinery for 25 years. Much of this was for semi-conductor companies at which time he gained extensive experience is high speed applications requiring the use of piezo-electrics, air bearings, FEA modal analysis. He received a patent for a machine which placed and re-flowed solder spheres at a rate of 30 balls/second. He has designed extensive conveyor systems, including the baggage handling system currently in use at O'Hare's international concourse. Expert has also worked with and developed tooling and grippers for large industrial robots. Recently Expert developed a Medical Cap Sealing machine for which he designed the control system in addition to doing the mechanical design. He is proficient in AutoCAD and SDRC and is an expert with Solidworks.

Expert developed and produced a prototype for a semi-automatic cap sealing machine. Designed machine using Solidworks and also wrote program to control the machine which ran on a PLC. Expert coordinated vendors and built prototype personally. It took 3 months from first concept to prototype which worked flawlessly at PMMI show. Expert also took photos and designed and wrote the sales brochure.Working from an old broken unit, developed design and drawings for a new mine sifting machine. The original machine was about the size of a car with a fully hydraulic drive system. Expert disassembled the existing machine and a new machine was made from a set of about 100 new drawings he generated. This machine was debugged and eventually ran perfectly. Expert developed a portable video prompter which unfolded on location into a small photography studio used to interview job candidates. The questions for the candidates were projected in front of the video camera lens by a two way mirror. Expert manufactured 6 portable units and two units that were built into permanent booths at companies facility. Expert has worked extensively with a connector company to develop a fixture to connect flex cables together, effectively connecting the flex cable from a device to be tested to the necessary test equipment. About 50 different versions for varying applications have been developed over a two year period. The units are manufactured on an Objet rapid prototyping 3-D printer which Expert runs and administers. Expert developed a night vision system for a anti-terrorism robot. The camera was mounted inside a large 2" tubular drill bit which would cut a hole in a building or car, and then insert the camera which came through the center of the bit. The camera had an infra-red LED light source to see in the dark. Built ten units before licensing design to robot company.

Expert may consult nationally and internationally, and is also local to the following cities: New York, New York - Yonkers, New York - Newark, New Jersey - Jersey City, New Jersey - Paterson, New Jersey - Elizabeth, New Jersey - Philadelphia, Pennsylvania - Allentown, Pennsylvania - Stamford, Connecticut - Baltimore, Maryland

Work History

Years Employer Title Department Responsibilities
Years: 1995 to 2006 Employer: Kulicke and Soffa, Inc. Title: Senior Mechanical Engineer Department: Responsibilities: Lead engineer responsible for concept, design, analysis and testing of various assemblies, and new machines or products for the world’s leading manufacturer of micro-electronic wire bonding machinery. Designs were rendered using SDRC- IDEAS for solid modeling and analysis. Awarded 3 patents and in a performance appraisal was described as “the quickest design engineer in the company” (from a staff of hundreds) with “creativity that is unsurpassed.”

Highlights include:

Wire Bonders – machine to attach wires from silicon chip to lead frame.
-- High Tension Air Guide - increased pull by 10X, an important feature that made accurate looping at 20 bonds/sec possible.
-- Designed ribbed bearing plate castings and related mechanics to mount magnets and bearings for several linear motor configurations (FEA)
-- Jack-Knife X-Y Table - used 2 rotary motors to achieve X-Y motion.
-- Microscope Mount - floating, with single lever to lock both axes.
-- Vacuum Formed Machine Covers - realizing a concept from marketing.
-- High Speed piezoelectric actuated Wire Clamps (using FEA).
-- High Frequency Isolated Machine Base (using FEA).
-- Split Axis Bonder. Designed high frequency overhead structure and linear motor configuration (using FEA).
-- Low-Cost Magazine Handlers (reduced cost by ~$1000/handler).
-- Compliant Rail System - to counteract thermal expansion issues.

Laser Pro – machine to place and re-flow solder spheres.
Lead Mechanical Engineer for LaserPro - a machine which placed solder spheres (.012" -.030" dia.) and laser-re-flowed them at a rate of 30 balls/sec. This challenging project required development of several new technologies including:
-- A High Speed Actuator incorporating an air bearing and voice coil motor. Since no commercially available air-bearing could withstand the accelerations, a new air bearing was developed which handled 8x more load than any similar commercially available air bearing.
-- A Micro-Ball-Feeder which singulated solder balls at >300 balls/sec. Developed with the use of high speed video, the singulation system used flowing Nitrogen and had no moving parts.
-- Received patent for Solder Ball Delivery System.

Die Bonder – machine to bond silicon chip to lead frame.
-- Wafer Stretcher - increased throughput by handling 2 wafers at once.
-- Wafer Transfer Arm/Elevator - with 1 rotary and 2 linear axes.
-- Dual Motion Die Ejector - sensed stress with piezoelectric needle to prevent die damage.
-- High Speed Bond Head Axis - used air bearing and linear servo motor.
-- Had 3 patent applications approved, but project was cancelled.

Test Division - Products for wafer/circuit testing
-- Spring Probe Life Tester - with adjustable speed and stroke.
-- Saw Cutter - used air motor (40,000 rpm) and diamond blade to cut miniature braids of .002” diameter wires without leaving burrs .
-- D Probe Feeder - fed eyelash-sized probes on a strip to bonding system.
-- Received 2 patents for new chip interconnect ideas.
Years: 1992 to 1995 Employer: Cybernetic Systems Inc. Title: Senior Mechanical Engineer Department: Responsibilities: Spearheaded development of mechanical systems and vision interfacing for manufacturer of screen alignment and inspection systems for the hybrid microelectronics industry.
