Expert is the inventor of surface mount (SM) assembly. He has set up over 500 SM centers in the US, Europe, Australia, and Japan. He initiated SM at Motorola. Additionally, he has considerable experience auditing SM work centers so as to determine world-class status. He can provide problem analysis and supply suggestions to improve yields and reduce costs while enhancing reliability. His work in SM was voted the "Best of Year" Award at Expo-SMT, two years in a row. He has also won the "Best of the Year" award from NEP/CON. His background covers the bare PWB, design guidelines, and surface mount paste and wave soldering with an emphasis on soldering to six sigma levels. Failure analysis is also a specialty that Expert offers. |

Expert has 15 years experience in SM technology and is the holder of the first patent in SM soldering to cover wave, reflow, and hand assembly. Before retiring from Motorola, Expert was their world-wide expert in SM soldering and cleaning. He has developed soldering processes involving both manual and automatic in-line. He is an expert in the application of nitrogen to IR no-clean flux and solder reflow. He has worked with solder joint design and reliability as well as PWB pad design and layout including finite element computer modeling. He teaches design guidelines, material selection, paste printing, component placement, soldering, cleaning, and testing for the University of Wisconsin at their Continuing Education Center.
Expert also provides an in-house service for surface mount seminars. These seminars cover design, materials, pad configuration design, soldering, cleaning, and test (quality control) for accelerated testing. Prior clients include H-P, Motorola, General Motors, and IBM as well as contract houses such as Solectron.

surface-mount cleaning expert |
He has developed aqueous cleaning and saponification processes to eliminate electromigration. He is . His soldering and cleaning work were awarded the US Reliability award and the NEPCON best technical paper of the year. As Lockheed-Martin, his PWB work merited him the top award in science 3 out of 7 times. He has developed a non-destructive one-minute test for insulation resistance (THB) that simulates 15 years of real time electro-migration testing. |

no-clean flux expert
no-clean solder expert
no-clean soldering expert
solder flux removal expert
solder joint expert
solder paste expert
soldering flux expert |
Expert developed flux spraying, preheating and soldering of no-clean fluxes. He is familiar with solder joint design for no-clean fluxes, nitrogen atmospheres for no-clean flux optimization, and the use of no-clean fluxes to eliminate electromigration. When no-clean fluxes are used it is no longer necessary to clean the flux residue off the soldered assembly. He has developed a test to determine no-clean residue integrity.

|
electroless nickel plating expert |
In recent years Expert has developed Ni-Au processes to replace HASL By doing extensive work with DOE technology, the Ni-Au process benefits now exceed HASL regarding flat surfaces and shelf life solderability. His processes with Ni-Au have been implemented worldwide and cost reduction and quality improvements have been substantial-in some cases improvements to 20%. The "black band" problem has been eliminated and product yields to 100% are realized in production. |
|
electromigration expert
highly-accelerated life testing expert |
By developing an accelerated test for PWB insulation and electromigration, Expert has reduced testing from 30 days to 1 minute. The 1-minute test simulates 15 years of real time. The test can be set up in one hour and the cost of the equipment is only $800. Expert has proven the results with many companies including IBM, Microsoft, and Solectron. His testing shows that if no-clean residues are not properly deactivated, field problems result.

|
solder paste printing expert
solder paste stenciling expert
solder paste application expert |
Expert has developed high resolution printing and stenciling processes using optical techniques. This involves printing from 8-50 mil centers. Expert has applied this printing to tape automated bonding.
|
|
solder expert |
By using Finite Element Modeling, Expert has found the significance of heel and toe fillets in FPT. From this knowledge, he has established new wave soldering and paste processes to improve yields to six sigma for companies such as Motorola, H-P, and General Motors. The new footprint designs and processes have improved cost by 65%. The new processes include PWB design and stencil modifications. Expert's work has completely eliminated intermittent field problems in joints. Internationally, his processes have been proven for quality and cost benefits.

|
printed-wiring board reliability expert |
Expert teaches how to design and manufacture printed-wiring boards to six sigma performance levels. He has initiated design, materials, processes, and quality control methods.
|
|
accelerated testing expert
accelerated solder joint testing expert |
Expert is proficient in using accelerated test methods (vibration, shock, surface insulation resistance, THB, thermal and chemical techniques). These methods simulate up to 40 years of actual product life. His ALT methods have real time relationships.
|
|
six sigma quality expert |
Expert shows companies how to design and build PWBs to six sigma performance. The technique covers design, PWB specification development, processes, and quality control. |
|
surface-mount component expert |
Expert has a novel background for both active and passive component placement. This background embraces dimensional stack-up, tolerances, placement error, and other placement controls to enhance yields.
|
|
yield enhancement expert |
A technique developed by Expert "Trend Analysis," identifies problems effecting production yields and yields solutions to production problems. By understanding process/design/material interactions, 100% first-time yields are achievable. The "Trend Analysis" technique is so simple to use that over-the-telephone solutions are possible. |
|
printed-wiring board fabrication expert
printed-wiring board laminate expert
printed-wiring board solderability expert |
In this area, Expert provides consultation in PWB fabrication, incoming inspection, laminate, and solder mask specification. He also provides a unique service in bare PWB vendor selection and survey techniques to reduce bare board costs by 25-30%. He developed printed-wiring board processes for the bare PWB and teaches in-house courses on how to write specifications to increase PWB yield.

solder joint reliability expert |
SOLDERABILITY MEASUREMENTS FOR SM PADS. This technique measures the surface integrity of SM QFPD pads. The assessment measures joint integrity by adhesion/cohesion methods and correlates to peel testing but does not require equipment and is simple to use. The cohesive/adhesive assessment criteria is a go/no-go technique that is easy to apply. The process includes a specification written plan.
