DeanM, How do you verify you have great results with the AutoSet feature if you do not check your profiles ? How does the AutoSet take into account large ground planes on certain areas of the board ? just curious

80 degrees F in the Summer. Also, "It is not recommended to store foods which must be kept at below 40� F for safe storage". Obviously we're not storing food, but the point is still valid. jdumont, Thanks for the data. I have a couple of Extech di

We've never heard of seen of such a thing either. We tried a clean sample board and applied con coat. Same process through out and we saw nothing. After speaking with the original operators who was curing the boards he had left the boards much longer

We've got a problem with a fine pitch board that has about .005" registration error at each end (towards the center of the board) when it's printed. Apparently we've got a case of board stretch generated at the fab shop. I still have to do some mea

this is the order that I use. 1. Teach pcb origin 2. Teach fiducial location 3. dial in vision on fid in mark info. 4. go into mount and verify that the primary image is on in x/y (after perfoming a teach trace condition) and then do any offsetts if

Guys, So I recently started working for a small CM in Southern N.H. We currently use 2 Magic Chef Mini wine friges to store the solder paste (63/37, RoHS). I've been monitoring the room temp (and humidity) and the frige temps all this week. The pro

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

Since I'm new to the forum I probably ask previously answered questions (that I have not found) but I would be grateful if someone could clarify this for me. I'm in R&D at a company where we design low volume (1k-10k) fairly complex PCBAs for our pr

Earl, et al, Boy things get old and cold around here fast. I promised more detail on my capactior problem and I thought I could drop something completely different in the same message and tell a tale of solder balls. First the caps. We still have
