Certain customers do give us CAD. USUALLY ODB++ but I've also gotten .ipc and .pcb . Many of our customers bought or inherited a design, and therefore have no control to generate additional files. Or, as you mentioned, they had another manufacture

The point here is if you can't get the full CAD files or the XY rotation files and all you get his Gerbers and a BOM. Most all contract manufacturers and some OEM's at some time or another have to deal with Gerber only files. If you find yourself i

So the NEW component is SOT-23? What is the foot print on the board?

We changed paste manufacturers rather recently and are now seeing SOT23s falling off after wave solder. These parts have a dual process... we stencil print paste, apply glue, populate then reflow. Only SOT23s fall off, chips are fine. We do not be

We run our process like that all the time paste then glue we use same profile as if we were just reflowing paste once in a while we have A plastic bodied part that has that problem we asume it was some mold relase still on the part basicly comtamena

What are the feasible options in mounting an alternative component onto a PCB that has a different footprint? PCB redesign is not a good option because the component is used on several other PCBs. The component is very small (8-lead SOT-23) so fabric

Hi, it seems like a glue problem to me. If you don't have enough glue on SOT23, you have no contact and the part is holded only by the paste, which results bad in the waver machine. So first I would check is the glue amount under the SOT. The second
