Dear all, Recently our lead-free samples being rejected due to very dull and sometimes grainy and very porous surface on solder joints. This samples was flow thru' the lead-free wave soldering with SN100C alloy composition. Referring IPC-A-610 D, le

We have a new SMT line, our customers are asking us the validation of the process. Not only the validation of the resulting assembled board (solder joint...) but also a validation of every single machine in the line (ex. stencil printer...). For exam

You'll still have to mop the tiles bye the way to keep them clean. Instead of tiles I've used epoxy coating over concrete and used ESD wax. Had to clean floor and add wax about montly. We had one of those ESD floor testers to check. Epoxy floor was w

I don't know of any data to support but I also believe that a concrete floor is just as good if not better than the money items. Have you ever left a fully charged car battery on you garage floor for any amount of time? She'll be dead. If anyone h
