Let's talk the whats, whys and hows of how you end up with a red box at the end of the day.

  • Pete you are right about the selective solder speed. Ground pads require a lot more heat transfer in order to get the solder to flow all the way to the top side of the board. A slower path with a large selective solder nozzle would help in a situation like this. Also there is a feature on the selective solder machine that allows the nozzle to "dwell" at a location to really put the heat to it. Though this can be tricky itself. Too much dwell and too much heat and you can literally cook a PTH pad right out from under a PCB.

    It's 50/50 art and science with that machine. We'll look to improve it on the next run!

  • this exists...


  • We get the stencils directly from DEK. http://www.dekpsp.com/psp.nsf/dek/stencils

    We go with the VectorGuard Blue series.

  • This machine hasn't put anybody out of work. It has simply made the work easier for our pick and place operators.

    To be honest, with the addition of this machine, we have discussed the idea of our pick and place operators to become more general "equipment operators". Expanding their roles to include everything automated. Stenciling, PnP, Reflow, Washing, AOI, etc. So if anything, this new arrival has given our staff more work!

  • your last comment is correct, more boards with less error should result in about the same amount of ding and dent as the past.

    Typically errors that result in ding and dent boards are things like PCB manufacturer defects, unsuccessful rework attempts, etc. And the frequency of those issues shouldn't change to much with this new process.

  • Spare Parts Bags will be stocked today!

  • It is judged on speed only. The particular kit being built needs to be 100% functional in order for time to stop. Judges will be monitoring each contestant. A contestant will hand their product to a judge to determine if it is functional, if it is their time is recorded.

    If this is a big success and we do it again in a year or maybe even six months, we might try to incorporate quality as well.

    We will however, be dishing out some side awards for things like: dirtiest board, worst solder joint, safest solderer, most stylish, etc.

  • There will be prizes associated with Gold, Silver and Bronze medalists. Both for the main competition and for the kids' heat. We are in the process of finalizing that right now. Stay tuned to the product page for updates on prizes!

  • Are you looking at the DP2006 series?
    Looks like it would be good for prototyping/low volume production. Maximum of 50 8mm feeders, might not be enough for your application?
    Overall though it sounds like it would fit your needs.

  • Didn't have enough space in that first reply...
    How quickly do you want to turn boards out? It sounds like speed isn't too much of a factor for you so this might not apply. But machines are commonly rated in CPH(components per hour). This serves as a maximum placement speed, basically if you had a single component placed over and over, it could do say 4,000 in an hour.
    It's like your car, the spedometer goes to 140 but you never really go that fast. Same thing here, rated for 4,000 but you will more than likely see something around 2,000.
    Hope this helps!
