Workshop Introduction:

LGA and QFN have fast become a common package type often used in many professional portable products. With any new device type there is always a learning curve for design, process and quality engineers who have to get to grips with the challenges that these packages bring. Each step of the implementation process for LGA/QFN devices will be reviewed along with results of practice process trials with these devices. Included with this workshop will be a set of optical and x-ray inspection charts for each delegate to use in manufacture. The workshop presenter is well known for his practical workshops and supported by Bob Willis unique process video experiments LGA/QFN are guaranteed to come alive.

Who should attend?

This workshop is designed for design, process and quality engineers responsible for introducing products containing LGA/QFN. Much of the material presented is extremely visual and practical making it ideal for manufacturing staff, like all the instructors workshops it not just theory, it’s a “How to Do It Session”

Workshop Topics Included:


Component Package Types
Component Construction
MSD Handling Levels
Solderability Testing Packages
Printed Board Layout on Rigid and Flexible Circuits
Solder Mask Layout Options
Lead-Free Stencil Printing Options
Placement and Component Packaging
Convection and Vapour Phase Soldering Yields
Visual Inspection Criteria
X ray inspection Criteria
LGA/QFN Rework and Replacement
Array Solder Joint Reliability
Common Process Problems with LGA/QFN

Conformal Coating Applications, Inspection, Rework & Quality Control Workshop

Workshop Introduction:

The use of Conformal coating has provided benefits to industry for many years either in the high reliability market sector or where products have to deal with extreme environmental conditions or simply in use in consumer applications. The use of coatings is seen in different industries like telecommunications, automotive and consumer products have benefited from the use of selective coating but for different reasons.

This workshop will provide a simple guide to the use of coatings, their application and process, product benefits, inspection and quality control. A practical session will also allow delegates to examine coated boards using different materials and inspect the coating application.

Each delegate will also receive a FREE set of colour Inspection Wall Charts covering coating application and common defects to use on their manufacturing shop floor. During each workshop there are opportunities to win some of Bobs interactive CD ROMs for best questions of the session.

Who should attend?

This workshop is designed for design, process and quality engineers responsible for introducing coating materials, inspection or auditing presented is extremely visual and practical making it ideal for manufacturing staff, like all the instructors workshops it not just theory, it’s a “How to Do It Session”
