Hi, We have been manufacturing a PCB, however it's been quite tricky to profile, as the edges of the PCB are reflowing before the center of the PCB. I have looked at the design, and there is a small power plane for 2.5 Volt in the center of the PCB

Grant, On those 'dry pads', where does the solder paste end-up after soldering? On: * Pads * Component leads * Someplace else [Where?]

As a starting point, consider that these component leads may not be getting hot enough. Measure the temperature profile on the leads that do not solder well to be sure: * Heating and cooling ramps are within the paste supplier's recommendations. * C

Hi, Thanks for the info. We are reflowing the boards, but just barely. Sometimes we get the QFP in the middle of the copper area not reflowing, and it's pain. The joints are dry, and I am not sure if it's caused by lack of heat, or the flux going ba

Hi Yes it is common to design for more uniform heat transfer during the soldering phase or even during the operation phase. It all depends on how bad the problem is during automated assembly or during usage. The only difficulty is that the designer
