I use Center Edge, and adjust stencil offset. It's very easy, you just have to give it the PCBs width. An other advantage is that If your PCB has scrap strips, and you lose them, or PCB changes, you can print it anyway.

I forgot to mention that we've tried to change the resistor on it.

Would suggest you have a re-look at your reflow profile. There could possibly be a higher thermal demand to solder the Pb-free version of these screw terminals considering that external plating has changed.

Help, experiencing discolor of a white solder resist paint after reflow of 250 degree, it turned yellow. Have tried many paints, no luck. Anyone knows one that wouldn't change color and holds the white nicely? Thanks for your support in advance.

I had this issue a few years ago with Kingbright LED's. The problem was extreamly random. When i changed to a different datecode my problem went away.

had tried all of that / went into proper data and changed the origin to the corner instead of the pin, it started working. thanks for the responce - ron

When you increase the blade length you have to use much solder paste. As a result, we will dry-out extra quantity of solder paste. If it's not a problem then you can use longer blades, just change/adjust the process parameters.

Hi, Walter, Why don't you try no-clean flux? We ever met the same condition, later, we changed to no-clean flux solved the problem.

That will definately cause a shorter tip life. The high tin in the alloy along with the higher temps are probably your culprit. We have noticed a degredation it tip life when we changed from leaded to RoHS on standard PCB's. Good Luck Chris
