Could you not second source a shaft on an old junk machine from one of these companies that sell used equipment?? Probably a pain in the $@#$%^ though. Good luck...one way or the other it sounds to me like your going to get the shaft....haha... chow

Water soluable dots will wash off after reflow. A water soluable liquid mask will work as well. dots are better for defined (round)holes, whereas the liquid mask works well with odd shapes.

We have our board house apply a peel coat mask that can be brushed off after wave or reflow. You need to brush off while it's still warm.

I am having reflow issues with small 6 pin SOT's. The joints on these components still look like solder paste after the reflow oven. I have tried adjusting the profile on forced air oven. Any recommendations as what to change in the profile or proces

The solder on the rest of the board looks good. There are no large components around these parts. We check the profile using a KIC and it met the recommendations of the solder paste manufacturer. I have not did a dip test of the board or components.

Wasn't aware of that. We're using a no-clean with RF pcbs, and that's something to bear in mind for the future - thanks.

Try a Siemens F3, if you can find one. They don't spec 0402's but it can easily place them.

I am concerned about delamination and other modes of damaging the board itself. Am I mistaken to believe that raising the entire board to near reflow temperatures (during the repair of a single BGA) may damage the quality of the board?
