Close but not to close, would have to be the spec. Or depends on your separating technology. Prerouted boards on a panel, you could go right up to the edge. V-grove you will need more distance, maybe 2mm's or more. The distance from the panel edge to

It depends. Are you hand breaking them, rotary knife or linear knife? Hand break you want to be about 5mm (and it isn't a great practice even then) with a rotart knife you want to keep parts probably 3mm, especially capacitors. With a linear knife we

I would assume we are talking about a radial leaded electrolytic cap? We use Electronic grade RTV (Dow corning 3145). It sticks good and can be removed if necessary. It is also pliable so you don't have to worry about CTE or other stresses that may

Earl, et al, Boy things get old and cold around here fast. I promised more detail on my capactior problem and I thought I could drop something completely different in the same message and tell a tale of solder balls. First the caps. We still have

Hi, I don't know what you mean by really odd parts. Are they SMT parts that have a flat surface to pick them up? If so, probably several machines can do it. I know for sure Siemens can place almost anything. THey will help you with any type of nozzl

Intermetallic compounds [IMC]: * Form during the alloying process of some metals. In soldering these are Sn, Ni, Ag, Cu, Au. * Do not accept solder. * Increase in depth in logarithmic proportion to both time and temperature. [So during the solder

I used to work with Chris. (neither of us are there anymore). What is he talking about is putting components into "pockets". The parts would come in, in sticks (tubes) but we wanted them in reels. At first we sent them out to be reeled, but that w

Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar
