Hello, Recently I have change our profiles. After I profile one board it look really good, within the paste spec. But I have noticed when board leaves the reflow zone and enters the cooling zone it looks like popcorn effect some components jumping o

Is it o.k. to clean my glue stencils in the same IPA stencil cleaner I use for solder paste? Also if anyone with experience in stenciling glue can lead me away from first time pitfalls I would appreciate that as well. thanks in advance

Too much Convection Airflow in the Reflow Oven blowing parts around ? Moisture Contaminated Parts out gassing ? Board out gassing? Just some thoughts, DG

please check the following also. in one of the cases we came across the second point was the problem. 1. the parallelisum of the conveyor. 2. the warpage of the board. 3. the stencil.(the differential height in the paste deposition of the two pads

>> try a linear ramp to allow the entire pcb to heat up evenly. What is your conveyor speed?

We have a Heller 1500W Reflow oven and need a way to catch boards as they come out of the oven. Does anyone have a suggestion as to how to do this. Your reply will be appreciated.

Questions are: * Do the BGA pads on the board take solder when you solder them by hand? * What is the temperature on the BGA pads during reflow? * What is the temperature on the other component pads during reflow?

I assume you mean the balls of the BGA, not pads (laugh it up guys - I said balls). If so, you may have a no-lead BGA or a high temp BGA.

RoHS BGA. No lead in it. > RoHS BGA. No lead in it. ok. this is not the case .It was sn/pb type...
