Hi, We have been soldering lead free BGA's onto products with lead based paste, and we have had no increase in defects at all. We have used a standard lead paste profile, so we are not altering the temps anything from what's recommended by the paste

Basem, I can't direct you to a dispensing machine, as I'm not familiar with them. But, I can tell you what we do. We specialize in short volume, prototype quantity runs. Since prototypes and short quantities are not conducive to volume operations

Thanks! Well, the procedure in the book says to first calibrate the mech aligner with the beam sensor, but that exceeds the X travel. I guess you can just eyeball it off the nozzles and then use trial and error. While poking around on the machine

I am sorry my friend, but I can't recall that specific error number. But it would help if you explain a little bit more about your problem. Remember that an error code Do Not necessary points to a direct root-cause of a problem. First of all we nee

Interesting observation Manuel. I will be blamed again for crying wolf but look below a lot more defects will soon see the daylight all related to lead-free. This information was posted at the tin whisker forum by Bob Landman of H&L Instruments.

For the most part there would not be a lot of change over. There are two primary boards at this time that would be run on the line that also use common components. At this point all but a couple of the pick and place machines we have looked at have t

Allow me a contrary viewpoint. I've had these things on my floor and had customers get outsourced evaluations done with them. Most expensive boat anchors I've run across. First the good points: The automated scanning and pattern recognition is go
