Which components are falling off during the second reflow?

We have witnessed capacitors falling off in wave due to mold release being present on the component.

check your reflow chain. it maybe vibrating causing DPAK to fall at second reflow.

Hi, We have developed various solutions for SPC in view of SMT production. I can tell you that the solution depends on the need you are trying to solve. Our solutions are: ASD (AOI/SMT Diagnistics) - Real-time collecting, detecting and popping hidde

yeah, me too, so we could watch them fall off chain pins

Hi DaveF already gave a good answer, which almost falls into the good attorney category. Let me try another good attorney, engineer answer. Depending on your environment place high quality sensors where they are needed, and record the T & H enviro

Make sure your epoxy dispenser is repeatable. DO an experiment , inspect every board to verify epoxy is there before the part is placed... Is there an epoxy residue left on the PCB where the parts fall off after wave??? We do the epoxy paste proce

These machines are very different. It falls under "there are no two machines alike" category. When you say the same profile, do you mean the same setpoints, or the same actual board profile that you get from running a profiler with TC's on the boar

When running some double sided reflow boards through the Heller oven, some of the caps/ res's are falling off the bottom side of the board. I understand if the parts are too heavy they wont stay in the molten solder, but these particular parts are no
