Chapter Tutorial Program (CTP)
Chapter Tutorial Programs (CTP's) are one-day technical events hosted by local chapters that feature a single instructor on a topic that is suited to that particular region. The purpose is to address the latest information or most recent issues on a specific technology.

Great Value! Half the cost of a tutorial at SMTA International and offered right in your backyard. Lunch, coffee breaks, course handouts, and a certificate of completion are all included in the cost, along with instruction by one of our best!
Today's electronic component packaging technologies of smaller packages (0201/01005/008004), finer lead pitch (0.4/0.35/0.3/...), bottom terminated components (QFN/DFN/LGA) and printed circuit board designs (high layer counts, finer lines, via in pad plated over (VIPPO), multiple copper thicknesses, copper routing, ...), increased thermal sensitivity, fabrication and assembly industry standards have impacted traditional assembly processes with addition of tight solder application, component placement, thermal management and soldering constraints. Using traditional, simplified mass production techniques are not sufficient to address tolerance margins that were considered insignificant and acceptable in the past are now critical to high yield, reliable products. This course will highlight issues with today's electronic designs and impacts when material limitations, industry standards and assembly tolerances are not adequately address during design, PCB fabrication, assembly and test. In addition, the concept of manufacturing, test, reliability by design will be presented.
What you will learn:
• Industry Standards Limitations (IPC/JEDEC)
• Component packaging impacts
• PCB design
1) Laminate Limitations – Rigid/Rigid-Flex/Flex
2) Via hole closure
3) Trace routing size/copper etching effects
• SMT and PTH solder design impacts
• Components with thermal management impacts:
1) Component design
2) PCB Thermal balance: X, Y and Z axis
3) Trace routing/solder mask/silk screen
4) Equipment limitation/tolerance
5) PCB array tolerance
6) Process tooling design
• Process control impacts
• Paste volume, thermal shock SMT and PTH, reflow process warpage
• Compatibility issues, low stand-off components
• Cleaning impacts
• Test and inspection impacts
About the Instructor:
Dale is a Senior Staff DFX Strategy Engineer with Plexus Corporation primarily involved with DFX analysis, root cause failure analysis and definition/correlation of design, process and tooling impacts on assembly processes and manufacturing yields.
Dale has been involved in surface mount design, package & process development and production for over thirty years in various technical and managerial positions. These activities have included research, development and implementation of advanced manufacturing technologies and interconnect techniques, design and development of Chip Scale Package (CSP) & Ball Grid Array (BGA) packages, PCB & PCBA support, DFM/DFX analysis of flex, rigid-flex & rigid PCB/PCBA’s including supply chain, process qualification and new process introduction for domestic and foreign low, medium and high volume production applications for consumer products, defense/aerospace and medical devices.
Dale has authored multiple technical articles and papers and is a frequent instructor/presenter globally on topics including PCB and SMT design, assembly, cleaning, and DFM/DFX. He is a past recipient of the Surface Mount Technology Association’s “Excellence in Leadership” award. He has been or is very involved with multiple industry associations (SMTA, IPC, INEMI), industry standards development, and symposium/ conference technical development committees.
