It sounds like your inspector improved quality and pre-staging your feeders dramaticaly increased uptime on your machine, thats great to hear. One cautiionary note, be careful not to flood your production area with parts off of your SMT line. With

It's been years since I worked with a Fuji. I only once resorted to the undocumented part class 255 (or whatever they call it) and that was when I was working midnight shift. The smaller nozzle working better than the larger nozzle makes me wonder a

Specs for Bow and Twist for PCBs (IPC-A-610C, 10.6. There may be an update by now). I also have a note in our quality guide referencing (IPC-TM-650, 2.4.22) and (MIL-STD-105D). In summary, a PCB should not bow more than 0.040" with all four corner

I've used rice, too. The trick is to make the bag big enough to hold down the part or parts, but not so big it interferes with the top side heating of the parts around it. I've never actually used lead or steel shot, the heaviest fill material I ever

Hi Just keeping this alive to see if anyone else posts. It seems to me that this might be a degradation due to life cycles of all products/services as they progress from creating high profits to being driven down and down in price. Topped off with

i have done this thousands of times. You are correct about no preheat, however it never seemed to be any issue for us. You do have to make sure that you do not expose any SMT comps. to the solder or they will become heat stressed/fractured. Connec

Claude, I know alot of equipment manufacturers that would like to talk to you about replacing all of your chipshooters! Of course, this will never happen. There probably won't be any sold until all of the used chipshooters are absorbed from the use

We use both labels and lasers to mark our boards. Since implementing the lasers, the downtime attributed to bar code labels on those lines have dropped to virtually nothing. We still have problems with the labels wrinkling during reflow making read

We use timers all over our shop to keep track of pot life on epoxy, paste work time, etc. The timers we use are from "Big Clock" or someone like that. They cost about $10. They keep time, count time up [run time] and count down from a set time. [
