Can't be 100% sure now, but Xerox used to be proud that recycled photocopier toner was used in the process of making black plastic bags. Toner was full of tiny magnetic particles that were attracted to the electrostatic image transfered from the c

The reason for going 1:1 with lead free is that it does not spread out like the pb solders. So 1:1 is really not necessary in my opinion. We go 1:1 anyway on discrete components along with other packages. You always have to make sure that the area

I guess I took too much time editing my response. :P The bottom line is that unless you're measurements are at least as repeatable and accurate as your machine's closed loop systems, it's a waste of paper *BUT* makes nice wall art for tours. I like

I do not think you can modify a 8*4 feeder to 8*2. Suppliers make a hell of a lot of money out of feeders so I would say they have that one covered. I think you will have to bite the bullet and buy 8*2 feeders. If you find out that you can modify

Fastek, In my opinion.. The thing that would make me confident, and/or attracted to a used machine sale is a money back guarantee. Some type of solid contract in writing that states a warrantee/guarantee agreement. This cuts the B.S. instantly. Wh

I do recommend dedicated tips and dedicated workstations. Make sure that your tips come in with no lead in the tinning. There is a new, green heat resistant table mat that is being used in the industry to identify lead free areas. If operators see gr
