Until you get the owner behind you, you won't be able to do much. And until someone gets hurt, and they sue his pants off, he's not likely to change (We live in a society where personal culpability doesn't mean anything and no one is expected to use

We have an SMT-5000 that we have been using for many years, but up till now the smallest device was SOIC, SOT23 type devices. Now I have designed a board that has a 24 pin TQFN-EP device and a 10 pin LFCSP_W device. I am concerned that this is be
