Hey pr...sure it's warm there, but I also hear that in that area where you live it's not too uncommon to have a kiddie pool in the front yard (with a couple of darkies in there), pickup truck parked on the front lawn, chain-link dog jails, with you o

We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin

We just placed a 56 pin QFN, 1 per board, on 10 boards and had zero defects. A good paste job, proper placement and a correct oven profile are the keys. If these are set up correctly, on larger runs your defects won't be zero but they should be le

Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper

Where could I find more information regarding the double sided reflow and flux problems with white tin?

Gregory, I think that the profile is too radical, i.e. zone 6 to zone 7 temperatures are too far apart. I would guess that the solderjoints have not all reached 183C in zone 6 which is why the uBGA's do not have a symmetrical ball collapse. You may

I have the opportunity to pick up a used 1998 Heller 1900WN reflow. I have no experience working with Heller reflows, nor have I heard much about them, so I don't know if they are good quality machines or not. I have concerns about issues such as z
