Hi, I have recently been asked if I had any information on the voltage capacity of a solder ball. I asked around and did a web search but came up empty handed. Usually people are concerned with the current carrying capacity of bondwires, flip-chip

In my experiance, I have seen no difference in profiles between nitrogen and air reflows. What I understand is that the Nitrogen blanket allows for a greater solderability to gold plated pads. I also found that when dealing with fine pitch componen

Chris, I am not a chemist, but my best guess would be that you were able to remove some of the solvents from the paste flux without exhausting too much of the activators. The loss of solvents could have cut down on violent boiling (violent boiling

Production of 50000, is this per year, per month, per week, what? As for your budget of 80000 Euro, that is no much to go on. For a basic SMT line, you need at least 1 paste printer, 1 placement machine and 1 reflow oven. If you have any through-hole

Hi: Many 75ALS573DW parts we reveived lately from one of our vender have some problem with its pin 2, an output pin of the tranciever ( probably resulting from EOS damage). Its impedance verse GND should be normally 3M ohm up. The parts we have measu

Hi There are a couple of options that you have: 1) have you tried to open the file using note pad, is it an ascii text format? 2)if it is a ascii file then you can edit the file by just leaving the centroid information. 3)OR call Fuji America at 847.
