      Yes, you can. But be sure to float the Current Ranger, it is not connected to ANY ground whatsoever or you can damage it. That's the key. You just pass the 12v high through it, that's it, nothing else.

    • @FelixRusu
      @FelixRusu Рік тому

      If you don't have the latest firmware there is a bug that will prevent AUTO-OFF to function properly (unit will still turn OFF after several hours). So first I would update the firmware, follow the guide here for that: lowpowerlab.com/guide/currentranger/programming-firmware-updates/ Secondly, there is a serial menu that allows you to disable AUTO-OFF functionality, explained here: lowpowerlab.com/guide/currentranger/auto-power-off-function/

    Is it possible to use dry film and ferric chloride? Is it possible to just print a negative on an acetate overhead sheet, laminate the dry film on the aluminum, develope the result, and then etch with ferric chloride or your phosphoric acid/peroxide mix? I figure if it would work, it would probably improve the definition for very small solder lands.

    • @FelixRusu
      @FelixRusu 2 роки тому

      I think it would work. The only way to really perfect the details is to try it and repeat until you get the results you're after.

      @lanceuppercut8220 2 роки тому

      @@FelixRusu Thanks for responding. Perfect results aren't really the aim, I'll save that for the PCB development, really all I'm trying to do is to get really small pitched traces. I just want to be able to solder QFN packages, other high count small pitch packages, and small SMD components. Do you think that would be possible with this technique?

    • @FelixRusu
      @FelixRusu 2 роки тому

      @@lanceuppercut8220 Quite possibly, but I haven't tried this specific recipe. The key is to not have an aggressive acid mix but rather one that will take longer but is easier to control and keep even in etching. If you're heating it to help the etch then mix it thoroughly all the time, you dont want cold spots where it will etch slower, you want uniform etching. Also copper heavy regions will tend to etch slower rather than small areas (and dull the acidity around those areas), so keep that in mind when you route your board and try to keep the copper balanced, or use grid pours. hope it helps you
