Is This the Right Way to Eliminate Counterfeits?


In an effort to stop or at least minimize the threat of counterfeit parts making their way into our military hardware, the DLA (Defense Logistics Agency) has mandated the use of DNA markings on approved products. The trouble is, original component manufacturers usually produce their semiconductors ...

Trojan Horse Partnerships Are Key to Success in Printed Electronics

Boston, MA — The traditional electronics partnership model of suppliers soliciting and meeting specs from brand owners and end users breaks down in emerging electronics applications like printed, flexible, and organic electronics (PFOE). Instead, material suppliers and manufacturers need to use new relationships ...

The Role of Pre-Heating in Electronics Rework


The Electronics industry, like any other, has been cyclical in its evolution. Through-hole, surface mount, single-sided, multi- layer, complexity and density have all changed and evolved and then changed again. Just as one methodology and approach seems to take root, the next big thing ...

Stencil Printing Challenges for Small Devices


The very small form factor of today's QFNs (quad flatpack, no leads), DFNs (dual flatpack, no leads), and µBGAs allows for smaller packages, and thus smaller electronic devices with more overall functionality, especially in the newer mobile devices. QFNs stand out because they provide  better grounding and better heat sink thermal properties compared to other SMT packages. Most QFNs have a metal pad on the underside for grounding and heat conduction. DFNs have a...

PCBA Bonepiles: The Neglected Green Revenue Stream Rehabilitated


Bonepiles. Everybody's got them. They're collections of PCB assemblies that are defective and can't be rescued. In today's fast-paced, production-oriented, revenue-driven environment, when an assembled board is deemed unrepairable, it frequently is written off and placed into a "bonepile ...

Are Your Materials Really Halogen-Free?


Though there is no official, government-mandated requirement forcing the production of halogen-free products and, therefore, the use of halogen-free materials, the electronics industry has arguably moved in that direction. This industry-sponsored effort is being driven primarily by ...
