Lloyd, could you get us a pic from the side? It looks to me as if the pads may be too small or far apart, but I can't tell. We normally use a 35 x 35 pad size on .07 centers when we have the luxury of designing them that is.

I am not sure what happened to that machine. One of my associates sent those pics to me a long time ago. I'll ask him next time I speak to him. Looks like it was around salt water judging the way the aluminum is rotting. What a waste of a cool mach

All: I am interested in how process engineers are both removing and adding markings to active devices. We have a job where we have to both remove the markings of and the re-mark SOICs. The markings on the devices look like they are pad or ink jet p

Volume that appears to be caused by wetting. Now remember most solder pastes will not "flow" across an entire pad. It will only flow where it is printed. In your pic, if the pad was covered and came out like this - it may be your pad. If it was

I would take the board in question and run it through again with your profiler to verify that no one has messed with your oven recipe, or your oven isn't malfunctioning. Also, a before and after pic attached to the post would probably be helpful to a

There are three versions of the CSM84, old, older and really old. The older machines can only do fun things around the PCB if you toggle RUNMODE 1 from AUTO to be UTILITY... then you can use the utility program "PIC" to trace around the PCB or do min

Hi Fred Thanks for your advice. That can cause bcoz may be Machine Vibration also. I did not check whether the parts were already upside down before advance.I'll do it in next run. We found that other diodes,see atached pic, were no troble duri

We are experiencing voiding on one of our lead-free assemblies on every part. The voiding only occurs underneath the parts and not in the solder fillet (see pic). We have tried baking, curing, washing, multiple pastes and everything else we can think

We were doing the same a few months ago, it took us 1 shift with 2 persons to drain it (we were repairing a leak), we were disconecting the resistors once they were not in contact with molten solder to prevent overheating... Here you have a pic of t

From the pic, it looks like you have a bad board; ENIG process issue. It used to be called black pad for SMT but I'm sure it's the same condition for T/H. Any good electronic lab should be able to id the black stuff. I would also send raw boards bac
