Smaller, lighter, and thinner electronic devices and their inherently restrictive design envelopes present several challenges on the road to their assembly and manufacture. Hardware for component attachment must perform reliably, despite the shrinking and limited footprints for fastener placement and installation. In addition, designers face reduced parts counts for weight savings and production economies. An entirely new generation of micro-fasteners has been introduced to help resolve these challenges when size and space matter. ?? This presentation will expand on the hardware demands and profile several advanced micro-fastener technologies gaining traction as suitable attachment solutions in the marketplace. It will include an evolving line of self-clinching and flaring micro fasteners serving today – and tomorrow — as practical and cost-effective alternatives to conventional loose hardware, welding, and adhesives. Specific applications and capabilities will be highlighted, based on existing end-product designs and anticipated packaging requirements down the road. The presentation will underscore how micro fasteners ultimately can help (and not hinder) key design and function objectives. By attending this special, free 1-hour webinar you will gain a better understanding of the new alternatives you now have available for your reduced footprint designs.

5. Who is PennEngineering?
• Penn Engineering & Manufacturing Corp. (PEM)
founded in 1942 in Doylestown, Pennsylvania, USA is
the global leader in the design and manufacture of thin
sheet fastening devices and installation systems.
• PEM is the inventor and continues to be the sole
manufacturer of genuine PEM® brand fasteners.
• We currently have regional manufacturing and
technical centers in two U.S. locations, Ireland and
China.

8. What is the “micro” in microPEM?
•
•
•
•
•
Threads as small as M1.
Pin diameters as small as 1mm.
Standoff lengths as short as .040”/1mm.
Attach sheets as thin as .003”/0.08mm.
Clinching into sheets as thin as .012”/0.3mm.
Smaller products are in development.

9. Why so small?
We actively conduct Product Teardowns and CSI
reviews for our customers. We have found in our analysis and
investigations that they often need smaller and smaller clinch
fasteners for thinner and thinner panels, to replace the
adhesives, rivets or welds they have been using. This is driving
us to provide more assembly options for when they are
designing their next product.

23. Do you use micro screws?
1.
Yes – only to hold an assembly together.
2.
Yes – to allow for disassembly and reassembly.
There are now two new engineered solutions.
24

24. Micro TackPin
Yes – to hold an assembly together.
Solution = Micro TackPin
25

25. Micro TackPin
• Intended for attaching two surfaces together, much the way a screw
would. The part clinches into the bottom member while retaining the
top member with a head.
• Tapered tip assists in assembly into the very small mounting hole.
• Interference band sizes hole during assembly to alleviate tolerance
concerns.

30. Micro TackPin
• What is the benefit to use a PEM® TackPin instead of a screw?
o The PEM® TackPin is stronger in pullout than the thread strength of a
screw of the same length.
o No risk of cross-threading.
o Less weight than a screw.
o Smaller than a screw, so designs can be thinner/smaller.
o No need for the cost of a nylon locking patch.
31

31. Micro TackPin
• What is the process cost savings?
Simplified assembly - press-in versus turned screw.
Throughput is faster.
No need to control torque settings to drive screws.
No scrap costs due to cross-threading, over installation, or screw
breakage during assembly.
o If adhesives are used, a PEM® TackPin can be used without any
recycling concerns that adhesives can cause.
