what is the solde finish on the bare board is it hasl? Are you using OA flux during assembly. A little more information would be good

Wow, I clicked on that link. Both myself and DaveF are in it. ..and this was from the '90s! Maybe it's time to look for another line of work. :-)

Yes dendrites can cause electrical shorts. The first stage of dendritic growth is a dark fern like pattern which reduce surface insulation between anode and cathode. In a more advanced stage the ferns transfer the plating metals of the conductors and

Yep that is a tough environment and no-clean will not work. The only two solutions you have is cleaning with a better cleanable paste (No-clean doesn't clean very well) Or you can go to no-residue and skip the cleaning. If you want to further discu

We want to start a discussion on the solar manufacturing market in response to a conversation with Anita Brown of Indium at the recent Productronica show in Germany. Since we referred to it in our show report newsletter we decided to start a thread a

Looking for help on getting information on understanding the physics of micro-fracture growth rate within the BGA ball (or solder joints in general). Hoping to find a fairly straight forward study on the concept/theory of this topic. I'm not a meta

Hi i am referring Tin whisker report JESD201A class 2 standard from Vishay. i can see at TC -55/85C using pbfree reflow there are 0 growth at 500&1000 cycles. for snpb reflow and the same temperature and same cycle significant growth can be found. my

we have an operator who is being prescribed to wear a bone growth stimulation system. Does anyone know if tis is ESD safe? Can he wear that on the production floor as long as he's grounded and have it stored inside his smock?

Without getting into an electrical field promoting bone growth... As long as he is grounded through heal straps and/or wrist straps, it should be fine. Although I imagine being grounded would neutralize the "Bone Grower"
