We are Currently running a Board and it seems that the SOT-223's on the bottom side have flux and water trapped under the part. Nothing has changed in our process and this is the only board that it is happening on. We are using Kester R562 water wa

If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? If I use 2 mil copper on the outside layers of a PCB, am I limited to what pitch of parts I can use? Specifically, will using 0603

How large of chip capacitor can we use reliably? I��ve heard they tend to crack. I��ve also heard if you pre heat the larger chip caps (1812 and above) before vapor phase reflow, they won��t crack. If I use 2 mil copper for a power supply board, a

30x30 is ok for CP65 not CP6

We have placed billions of components with our Mydata's. No issues with ESD.

Has anybody had issues with the Mydata centering jaws causing esd and part damage. I understand we can lower the force on the components but ESD is my main concern. In the past I heard of companies testing the centering jaws because of this concern.

Hello We a Mydata and put all kinda of components with the midas unit, but never had problems with ESD, and some of them are very delicate parts, perhaps like our colleague said perhaps you should look at the trays or feeders that you are using, pe

hi Bob, Thanks for the info. I understand your comments, but I am looking for specific guidance, If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? (I realize this is dependent on h

Ceramic capacitors larger then EIA size 1812 are known to be very susceptible to thermal shock damage due to their large ceramic mass.
