Hi Jacqueline! Do these joints that you're having problems with happen to be on fine pitch solder joints? Are the fillets staying attached to the foot and separating from the pads cleanly? If that is true, are there many vias concentrated aroun

i have a problem with some units that had one capacitor only soldered in one side, the geometry of the capacitor is 0805, our product during his life suffer a lot of stress (due temperature or vibration), some of those units are already with the cost

If you've told your experts in Germany and US as little as you've told us, I'm not surprised they don't know dip. Sorry, I just snapped there for a moment. That wasn't politic, was it? Yes, it is possible that the other solder connection on this c

Mile, Please tell me more about your soldering process: - Are soldering process parameters the same for all three pins? - Is unsoldered pin connected to thermal heavy copper polygon? - What is your board surface finish? HASL? - Sn/Pb or LF process?

We'have been working on an issue regarding aluminium capacitor placement in PCB. In fact, we have twisted (shifted) capacitors. Through root causes analysis, we confirmed that this phenomenon is happening during reflow process (no issue on placement

Hi We are experiencing serious problem with ceramic capacitors. They are with low electrical resistence and the problem is intermittent. We found some of them with micro cracks but not all. What could be the causes for this problem? We are su

Takfire Questions are: * Why does your customer think the capacitor is the issue? [What are we thinking? Of course the capacitor is causing this voiding problem. What else could it be?] * What are the type, construction, end-cap material and plati
