we have been doing reflow on SLX PCBs and found out that when lidding, the components have been shifting. Has anyone been doing low temp lidding on SLX PCBs using the flowstar 4036 soldering system? If so, what low temp solder was used and profile

I want to check this becuase we are exporting the PCB & there is problem of components missing at customer end in some PCB while we are doing 100% AOI & then ICT testing. These components are checked by both. there is no possiblities that the compone

Thanks for your feedback, both of you. But my problem is that we have high mix and low volume its obout 50-200 pieces. And we also have manual paste priter so the solder on the pad look always diferent. I believe that there is the problem but I cano

I checked with MVP after Reese's comment, they use special color lighting in addition and have many customers detecting lifted leads successfully. It doesn't really matter unless your looking for a better AOI system/supplier. Hopefully your equip

Hello Patejl, Many AOI machines have issues with lifted leads. I recall SAKI failed to catch lifted leads on my test PCB when I evaluated them. If you are looking for replacement equipment, check out MIRTEC. We now have four of these systems confi

Take a few parts from the reel and look close at > the parts to make sure the bottom surface of the > leads is below the bottom surface of the body. Yes I did that and they are below the body. I found the problem I think. The solder mask is abo

The design of this machine makes it difficult to lift the pump out to clean as often as it probably should be. We are seeing dross on the solder source side of the boards. Does putting wax in the solder pot help reduce the dross? If it does help, wh

Hi, We are having some serious issues with placing the Luxeon Rebels. The problem is caused by the components sticking to the tape. We don’t know what causes it, but I remember to have read something about components sticking to the tape on this For

Hi Folks, I'm looking for detailed information about the different composition of circuit board pads. We have been experiencing some issues with our solder, and I would like to know the differences between compositions. I do know that we ran a cust

I've done minimal research to this point and understand my issue with solder on the double sided boards is due to oxidation that occures on the unpopulated pads when the board makes its first trip through the reflow oven. We did run both sides in a
