Hola Evtimov, I do the same with my Solder Paste Jars, there is a label that is filled by the warehouse guy & by the line operator; time & date the jar arrived to plant, time & date the jar was taken to production line (out of the refrigerator) and t

SWAG has it. Carriers for SMT are a great idea, especially to mitigate sag, and allow some savings in setup. Fixturing setup advantage: You could fixture everything to a fixed width, and eliminate rail setups throughout your lines. Trade off the f

If it took you a long time to get it through pick and place or you had to do a lot of hand add of SMT parts, your paste can start to dry out especially on the small deposits. We've seen this time and time again. We've gotten way better at quickly p

Your solder looks like it hasn't had time to reflow. Are`the pictures of an aluminium substrate ? So just positing a theory your boards need more soak time, the solder seems to have formed little hills/mountains and then cooled off before the surface

Bruce, I have different size electrolytic caps. Most of them should be no issue to pick 8 at a time(5-6mm) Can't I decrease the speed of the head when placing these parts? I would love to place slow motion 8 parts at a time than going 8 times with t

Hi Phill Thank you, It´s a possibility because that model has many false calls and real defects, but only in one component. A while back we had a similar problem and we changed the component number to a new one, and the cycle time was better, but th

I already understood thank you very much. In fact, between the oven and the AOI we have a conveyor that measures around 6.5 ft. Only in this case we set the time of the line so that the process was efficient, now that the AOI increased its loading an

What is the main considerations when comparing if production should use AOI vs Manual inspection? Is it only volume/time based? (of course assuming the reliability of automation is as good, if not better than humans) So long as AOI can produce reli

Greg, The operating parameters for Wave Soldering are: 1. Preheat Temp. (80-110 c, board surface); 2. 1.5-3 secs dwell time in solder. This, 1.5 second, is the time required for both the lead and solder to gain sufficient heat and as a result "tinn
