...and, bake those parts. A lot of times, moisture will cause problems like you mentioned in the center of the part. (Old components will get this condition often)

What about the relay that controls the heater? I've seen that problem on conceptronics ovens. The relay would latch on and never turn off.

We swapped the solid state relay for zone 5 bottom to zone 5 top but the problem came up once a while. As for noise protection, there are jumpers at E1 to E8 and E9 to E16. They are hardware filters and prevent noise spikes from affecting thermocoupl

Wagoner, Try switching to a transitional paste designed for no lead parts on a leaded board. Running your current paste at higher temps will dry out your flux too soon, which may be your problem.

You should have no problem using lead-free components with tin-lead solder. Is your reflow oven IR or hot air? If you are using an IR oven and the components are white or light colored, they may not be heating up enough for the solder to flow on

We are looking at getting an IR rework station. Some have mentioned microfractures in parts made of material that absorb heat differently. They have not provided any details though. Has anyone experienced this problem or know anything about it?

You may be creating more problems by teaching feeders. We use one type of 8mm for whatever amount of feeders we have loaded. You shouldn't have to teach 10-8mm feeders with 10 different feeder names. Use only one.

I think it might be the feeder banks, that is causing the problem. I've tried picking a SOT-23 component using head 2 spindles 1-4 from a rear feeder bank and it is picking off centre. Doing exactly the same, but putting the feeder in a front bank it

Hi, We think the problem was the z orgin on the X,Y, table. After calibration and adjusting the proper things are much better. Thanks to everyone. Rob
