I would love to jump on a program like that, but allocating the resources is hard. I am going to need to put together a proposal on why all of this is going to be useful to people that do not understand. I am having a difficult time just writing up

To expound on what Hussman says, Wikipedia defines Delta (a Greek letter that looks like a triangle) as, "A macroscopic change in the value of a variable in mathematics or science." Anyone who's taken Physics would know what this is. In soldering,

Heck no, I mean we print relatively slower on complex boards, as in 1 inch/sec (25.4mm/sec), and maybe 2 inches/sec. (51mm/sec) on less complex boards. SMT is not a bottleneck in our plant and printing never the bottleneck in SMT, so I see no need t

Call me jaded, but this sounds suspiciously like the classic "our other supplier didn't have this problem" but the other supplier was hand soldering the headers, and finally requoted the job with that in mind so the customer moved on. Granted, ther
