So yesterday, I failed at my first attempt at building a completed module:cryyy:
I was using a LOC diode with a rkcstr driver I set it to 300mv with my test load from Flaminpyro.
I soldered the diode directly to the driver. My biggest concern was leaving the tip of the iron on to long, and overheating the diode. I had already pre tined both the diode pins, and the driver board. Even used some flux. When I was finished I fired it up. It worked YAHOO, I did it.

So now it's time to put the bottom half of the aixiz on. what I didn't account for was the lack of space in the module, length wise.
When I soldered the diode to the driver. I didn't do it close enough. So when I screwed it on, it twisted the pins on the diode around them selves. When i fired it up again, it sorted out the diode.:cryyy:

So what's the best way to avoid this?
It doesn't look like their is much to sand, or shave off the rkcstr.
Should I use short wires to connect diode to the driver, and then stuff them in the aixiz?
I have big fat shaky hands:eek:. So I don't want to get the driver to close to the diode for fear of getting solder on the diode it's self, and sorting it out again
Also, looking at it again. If my next diode's pins are just as long. It looks like I will have to snip the tips of them to bring it in closer to the driver. Are they easy to snip, or are the really brittle and prone to snapping off?

I just ordered two more diodes and one more driver from flaminpyro.
The other driver should still be good. So I will have two more chances to pull this off before I throw in the towel. Any tips would be appreciated, Thanks.

Use a fine file or fine grit sandpaper to shave down the sides of the driver. You SHOULD be able to remove enough of the PCB so it won't grab the side of the module when you twist it on.

What I do is use shorter pins (you can snip them off with diagonal cutters very easily) and put the diode in aixiz module head very close to the Rkcstr driver, it helps to cut off the unused pin so that you can solder the pins easier.

Make sure to line up the Rkcstr driver with the edges of the Aixiz module so that when you do screw on the back end of the Aixiz module it will line up correctly and can screw on.

It also helps to make sure the wires that you attach to the battery side of the Rkcstr driver are very close to the Rkcstr driver, and also you can use a pair of needle nose pliers and press the wires together so that they are very close to the driver and slender enough to fit through the hole of the Aixiz back end.

Just becareful when screwing on the back end and if you feel pressure just stop twisting it on. Its ok if it doesn't screw on all the way.


you really don't even need to use that back end of the module...

exactly what kendall said.. ;) use shorter pins and the driver should be almost touching the diode.

OK, I will follow these tips next time.
This time, I will know what to look out for. It's just that I was so excited that it fired up the first time. That I just jammed the bottom half together. With out thinking about it.

I do need the bottom half of the module, for my build. I will be mounting a spring to the bottom, insulated by a rubber washer for the + input.

Now, I'm just waiting for the dang u.s.p.s to deliver my package.

Thanks for the tips

I sand down the sides and the "battery" end of ALL of my Rkcstrs that need to go inside the module.

Peace,

you dont need the back half of the module but i usually use some non-conductive foam to satbilize the driver to keep it from bending the diode pins.

You can use a small pipe cutter to cut off the very end of the aixiz module as well. This eliminates trying to get the wires through the small hole of the aixiz module.
I usually only use enough of the module to cover the threads of the head of the aixiz, the rest I throw away. I don't know if it helps, but I think it would make the heat transfer a little more efficient than without it.

The rkcstr drive is already small enough to fit inside the Aixiz module.

I'm assuming you just had the end of the pins on the pads?

Most time i will actually clip the pins down a tad if they are too long. Sometimes the pins will hit the big capacitor on the driver and not let the driver sit directly on top of the aixiz module, as the driver needs to side right on top of the aixiz module in order for it to fit inside.

As long as the driver is sitting right on top of the module, and you have it centered, the back half will screw on with no problem.

Are you sure you're using an Aixiz module or is it possible a Sure module? They look identical, but the Sure module barrel is ~2mm shorter.

I use my cheapo bench grinder and dremel cutting disks to A: grind down the edges of big PCBs and B: cut holes in modules if I need to.

I've heard other people say that the modules come short sometimes. I bought one and the person who made it had to Dremel out the back hole to fit it. The driver was right up to the diode so there was no slack. The module was just to short.
