The idea behind the new microPEM TackSert pin is to eliminate threaded hardware in small, compact electronics, like credit card readers, SIM card ejectors, and the growing class of wearables, increasingly important as electronics get smaller.
Thanks for that input, bobjengr. I've done several posts from that show, as have the rest of us who went. Here are my others: igus plastic bearings http://www.designnews.com/author.asp?section_id=1392&doc_id=271925 3D printing http://www.designnews.com/author.asp?section_id=1392&doc_id=271813 Baxter Robot http://www.designnews.com/author.asp?section_id=1392&doc_id=271846 SABIC's carbon composites for medical devices http://www.designnews.com/author.asp?section_id=1392&doc_id=271732 Disease-fighting materials http://www.designnews.com/author.asp?section_id=1392&doc_id=271712
Ann--I have used Penn fasteners and can "testify" they really do a great job depending upon the application. The micro-devices are ideal for the applications you mention in your post. I was very surprised at the shear and tensile some designs can tolerate. I'm really sorry I missed the show. Certainly seems like a great experience and I look forward to other posts you make relative to your visit.
The microPEM pins are so tiny you can barely see them with the naked eye, at least with my eyes unaided by glasses. The sample Penn gives out is so small and lightweight--2 super thin 1.5in diameter disks fastened together--it kept flying out of the pocket in my notebook (not a computer, an actual paper device I use to take notes on). I was also impressed by the many uses of silicone for adhesives, coatings, and other apps: it's a truly versatile material.
University of Southampton researchers have come up with a way to 3D print transparent optical fibers like those used in fiber-optic telecommunications cables, potentially boosting frequency and reducing loss.
