Expert is intimately familiar with corona discharge technology, theory, equipment, and applications. He used this technology in the assembly of electronic connectors used in the smart missiles/bombs during Operation Desert Storm. His work has emphasized controllable, repeatable corona processes. He routinely develops and implements corona discharge processes for companies worldwide. He has written technical papers in this area and has received a US patent for a corona discharge process which solves bonding problems.

Expert has extensive working knowledge of adhesive bonding of electronic components to various substrates such as thermoplastics, thermosets, elastomers, and metals. He is actively involved in a broad range of applications including electronic connectors, switches, semiconductors, backshells, and other related devices. He received a US patent for a 3-dimensional surface treatment adhesive bonding process that was later used to manufacture electronic connectors.

A significant portion of Expert's career involved his position as the Director of Engineering and Quality Departments for an international electronic connector company. His responsibilities included product design, introduction of new products, manufacturing engineering, and supplier certification programs. He developed and implemented new technologies for advanced manufacturing assembly processes.

Expert has consulted with companies worldwide regarding ink adhesion processes including both military and commercial clients. He has invented a state-of-the-art process which resulted in superior ink adhesion and print quality. He has invented an ink decorating process to be used on 3.5-inch micro floppy disk shutters. With excellent knowledge of ink adhesion on difficult to bond polymers such as acetals, polyesters, polyphenylene sulfide, liquid crystal polymer, and other thermoplastic and thermoset polymers, Expert routinely recommends types of inks and suppliers to his clients.

Expert has extensive experience in adhesive bonding of metals to plastic substrates such as thermoplastics, thermosets, and elastomers. He received a US patent for a metal-to-plastic adhesive bonding process. This technology was used to bond BeCu metal contacts to polyphenylene sulfide insulators for electronic connectors which yields superior adhesive bond strength and is qualified for commercial and military/NASA applications. He has applied this process to electronic connectors, switches, semiconductors, backshells, and other related devices.

Expert routinely diagnoses and solves paint decorating problems. He is well acquainted with paint decorating computers, sporting goods, and other commercial plastic and metal products. He is experienced with many substrates including ABS, polycarbonate, and liquid crystal polymers. He works closely with injection molders and end users and often recommends paint suppliers and finishing companies.

Expert has years of practical and theoretical experience with ultrasonic welding processes and equipment. He has worked with 20-kHz and 40-kHz amorphous and semi-crystalline resins and is knowledgeable of the variables that influence weldability. He has set-up welding processes (including fixtures) for many commercial and military/NASA applications. He has been deeply involved with welding high performance engineering plastics such as polyphenylene sulfide, PEEK, and other similar polymers. He can diagnose welding problems and recommend equipment and has intimate knowledge of various joint designs and injection molding processes.

Expert routinely implements finishing processes and solves related decorating and finishing problems. Emphasis on establishing controllable and repeatable processes for commercial and military applications. His finishing process experience includes spray painting, ink printing, hot stamping, screen printing, ink jet, laser marking, plastic labels, electroless plating/shielding, precious metal plating, and hot-tin/solder dip. He has developed state-of-the-art techniques for superior part finishing.

Expert has developed and implemented advanced techniques for bonding, joining, welding, and staking similar and dissimilar plastics. His broad range of knowledge in this area includes electronic components, computer equipment, and automotive applications. He has worked with acetals, polyesters, polyphenylene sulfide, liquid crystal polymers, and other high performance engineering thermoplastics.

Expert developed and qualified military/NASA approved laser compatible plastics and processes for marking electronic devices. Expert maintains that laser technology replaces conventional ink printing and offers significant advantages such as permanent high quality text, excellent print contrast, no curing, no metal engraving plates are require, and no hazardous solvent are used. He has written two technical paper on this subject.

Expert has extensive experience in designing and manufacturing products assembled from PPS. His major emphasis has been working with PPS on secondary manufacturing processes including adhesive bonding, joining, ultrasonic welding, printing, laser marking, and other assembly processes. He developed and implemented the first Military/NASA-approved laser marking process on PPS which yields unprecedented print contrast and quality. He has assembled extensive environmental test data containing electrical and mechanical performance after secondary processing. He has applied his knowledge of PPS to electronic connector, automotive, medical, and computer applications. He has been a speaker at NEPCON West, the Society of Plastic Engineers, and the IICIT (connectors) symposiums concerning manufacturing components made from PPS. He has written five technical papers related to secondary manufacturing processes on PPS and other high performance engineering plastics.
