Are You planning to produce a RoHS compliant product? If You just are going to reflow non RoHS compliant components with a "RoHS oven profile"; make sure that the comps. can withstand the higher solder temperature. As we see it; it is a big reliabil

Makes us wonder how well the connections on the component match with the pads on the board.

No delta T issues as I am not actually reflowing the component to the PCB. This is for moisture sensitivity testing as per JEDEC 020C Standard. Trying to duplicate a profile in the standard and am having trouble reaching a component ramp rate of 3

If the problem appears to be random... we had a similar problem. We found that the belt which feeds the PCB through the reflow oven would jump or lurch ahead. It was barley noticeable but if you have identified the frequency and time of the compone

I am testing some BGA's (PBGA 30mm x 30mm) to evaluate the maximum ramp rate we can achieve in our reflow oven. Temperature is being measured at the body(top) of the component / not leads. After several trials (with various oven settings), the high

our biggest problems with these parts is them laying on their sides after placement with a certain machine that we have. make sure that you do not have a planarity issue as well menaing that the leads are indeed below the body of the component. I a

Makes us wonder how well the connections on the > component match with the pads on the board. The pads are actually larger than the leads on the part, but I think we may have figured it out. We believe the conveyor vibration is causing it. When we

If the board is just not reaching the temps you need, you could place them in an oven to "preheat" them. When I was building a rather thick board with a copper core I had to do this. Since we were only doing small runs it was feasible, I don't know y
