Are you sure you are using the correct solder paste question, once again. How many cycles times allow to proceed in reflow for these type of packages. => Dunno. What does the supplier say?

So what exactly is a feeder protection plate and how does it protect the head when it decides to continuously accelerate until it achieves its allowable travel distance on the machine? How often does this happen?

Hello Russ, I'm not quite sure I understand your question. Are you saying that you must hand solder these connectors because the gold plating doesn't allow other though hole processing methods to wet the solder the length of the pin in the PTH? Reg

Jim, you are right in this. these connectors have long pins 1/2" or so that protrude through the board and are used for mating into a female connector on some other assembly. due to both length and "no solder allowed in contact area" criterias thes

The major profiler companies [ie, KIC, ECD, etc] give away FREE Excel spread sheets that list everyone's oven and paste and allow you to input board characteristics and then it suggests a profile. Go get one.

One more variable I've remembered - pad height with respect to solder mask height. Pads being too low can cause stencil "gasketing" problems that in turn allow more paste to be deposited than needed. Are your fabs HASL or some other media?
