Assembly with Solder - An Unblinking Look at
While soldering holds many benefits in terms of offering a means of mass assembly of components to PCBs and is fundamentally simple, its application is much more complex and fraught with opportunity for defects to be generated, but it is also the demon we have elected to live with, for as the old saying suggests: "Better is the devil we know."
BEST, Inc.: Branching Out to Bare Board Rework
Bob Wetterman, president of BEST, Inc., joins Guest Editor Mark Thompson to discuss the company's move into reworking unpopulated boards, building products that facilitate faster rework and repair, and IPC certification and training.
Sustainability: What and Why?
Joe Fjelstad writes, "The resources of our planet are limited and thus are diminishing as we continue to unleash and ramp-up a seemingly never-ending flow of products to both serve and amuse us with output of the global electronics industry likely to be nearing the top of the list of 'offenders.' In that regard, we are becoming victims of our own success, to one degree or another."
Thru-hole Lead-free Soldering and Rework Concerns
Despite the industry's switch to SMT from thru-hole for almost three decades now, thru-hole has not disappeared yet, and don't expect it to any time soon.
