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.
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.
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.
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
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
