Tangent = ground the secondary

The operators on a spot welding line complained of getting shocks.  Since the tooling and parts were all steel, and conductive, it was not taken seriously, but we did some tests to be sure.  We found a voltage on the secondary of the spot welding guns - the copper shanks that contact the part and conduct the welding current.  The fix was to add a ground wire to one side of the secondary of the weld gun transformer.

Practically all electronic devices today contain metals that may be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Conformal coatings present themselves as space-saving alternatives to enclosures for protecting the circuit boards of automotive electronics. They can also provide electrical insulation.
Design for manufacturing (DFM) in mold production means that mold designers evaluate the manufacturability of their molds in the early stage of mold development by collecting all relevant information and applying it to their designs. They also have to consider many other factors, including flow balance, structural stress, and assembly tolerance, in order to ensure successful molding production.
Some adhesives provide strong structural bonds but take hours to fixture and attain handling strength. The technologies that offer the fastest cure do not bear loads or withstand stresses. A new class of adhesives aims to make both stick.
The continued growth of wireless health is a near-certainty. And engineers will be the key to developing and advancing technology solutions.
