Hi, I can understand why a lot of people are concerned about this deal. I have some little experience of this. I used to work for an electronic manufactory company 5.000+ employee (divided on several sites) and it was sucked up by an investor Corp. W

I'm in the market, also, but vasilating over cost vs performance. I've also used both. In general, the LPKFs have more bells and wistles. On the LPKF S62, I love the tool magazine, and vacuum table. And, the fiducial recognition camera is great o

I'm in the middle of developing an ESD program at my company, trying to adhere to S20.20 as much as possible (and the suggestions of the ESD audit conducted before I got here). I've been discussing the pros/cons of pink-poly foams and black foams.
