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.

electronic component-to-substrate adhesive bonding


thermoplastic bonding

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.

electronic interconnect system

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.

ink adhesion

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.

plastics printing

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.

thermoplastics injection molding secondary operation

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.

laser marking

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.
