I'll be honest here, while training people to IPC standards is good. Zero% of our clients or future business inquiries ask about things like IPC610, even stipulating ISO is rare, as long as there are systems in place of some sort.

Do you think IPC able to help you to save cost for you company thru rework / repair and modification course? - Is there any ROI from the course attended such as 7711/21? - Does your company get more business or credit via IPC certification? - Does th

You're correct. This design will have a record amount of 0402 rework for tombstoning and misalignments. Suggest that the pads on each end of all components be the same size in order to balance wetting forces during reflow.

I've not seen it on a solder joint, but I've seen it on an SMT pad that had been skipped in a wave solder operation. The boards were under inspection for poor solderability. We never really pinpointed the cause. It would make a perfect 6 pointed s

We do this quote often with our older Summit machine. there are a few ways to do this. all of these are assuming you have parts on the boards already and are working around them. 1- if you have a good tech that can add solder to the pads on the PCB a

You may want to tack a coup[le of leads first, making sure that the component is fully seated against the PCBA. Or what we do is apply solder to the E-Pad and the lead pads and then hit it with a "heat gun" until the solder melts on the E-Pad and th

I have some fine pitch QFP's to rework with our smt rework system (forced air). There are no intitial concerns in removing the component (we havent actually begun the rework process) however, installing a new chip presents a problem. The QFP has

one more thought on this, When these boards are built new do we not have solder paste on the ground pad and then reflow? Has this caused any misregistration for you? I am assuming that you are not pasting the leads with the ground pad correct? I

I need advice for locating 23 Gull wing LED's (all in a straight line) in the x,y, and z axis for a SMT PCB. It is a Hewlett Packard LED (P/N HMLA-QH00-01). The application uses a CCD to detect the position of a ball which floats in a resevior for
