Hi Michelle, Due to the dense population of through hole on some boards, after a 35 minute wash, some connectors or battery holders remain wet. Currently we put them into drying ovens at 70c for a Minimum of a half hour. We do occasionally air dry un

Hmm, that's a fairly old machine, even older than mine! (I have a CSM84 PA130640). Anyway, it is best to program the machine from CAD system data, I wrote a little program in C to read in the component type and XYR position, and produce the file in

I have a question regarding the csm66, i have that particular machine - but have 2 problems : (1) Movement speed - its set at 100% but just crawls in the run mode .. i dont understand why. (2) I have a teaching camera but it does not recognize it i

We've done many fine pitch parts using only global board fids with good results. However, if you're working with flex or flex/rigid designs, I would never use global or panel fids for fome pitch placement. We always request addition of local fids u

D8->D7) and D18 (D18->D19->D18). Well... it looks like D18 had an issue so it went to D19 but when it finished the D19 reel it went to D7!. I endeed up with D7 parts in place of D18. These are both 0805 resistors. Has anyone seen this ? Did I mis

In an oven over 100 C any moisture will escape through vents. There will not be huge volumes of moisture in the oven when you are baking components so it should easily escape through vents / holes in the system leaving you with a humidity of near zer

I experienced warpage on a 7'x 13" long board, unfortunately my oven does not have center support. I use stiffeners on both of the short ends. It fixed my problem. Some of the things I was experiencing with the warpage on the second pass were placem

Thanks Jeff. Guess I didn't tell enough of the story. I can get the 1st part location taught (it looks like) but when I try to pick a part from the tray using adjust assistant (F6), the head changes to the appropriate nozzle and tries to pick from th

Hi Dave I agree with the 2nd point (sloppy process management) if the failure rate is higher than 5%. But this is 0.083% case, and only happen once in the blue moon. As I study about the re-flow profile for the last whole week, current parameter se
