With request of a few fellow BLF’ers and authorization from Mattaus I took his BLD20DD and more or less expanded the ground ring, added a capacitor on star 4 (for the off time firmware) and de-stopped the VIA’s everything else is completely the way Mattaus built it
Love it. I’ll get a set just because, already got my need taken care of with wright’s adapter but I’ll still get a set just for having the off-time cap pad on the bench for FW testing.
I think I’ll try to add a dip switch to the cap so I don’t have to desolder to flash.
I just placed an order for this, and a couple other BLF creations. My first Oshpark order! I really should have ordered them earlier since my hot air rework station arrived today, and I don't have many things to use it with aside from reflowing some LED's.
Allright! Thats it, now you’ve gone and done it WarHawk. Now I’m gonna have to buy a hot air rework station and start putting these drivers together myself. Thanks alot.
Digging my heels, kicking and screaming”no, no, no!” I can be a bit obstinate at times. I have no intention of trying to put together even a small percentage of the project boards. I just wanted them all in one place and I’m vain enough to have wanted a sticky of my very own even if I did little to earn it.
By the way, is it ready to post as a beta, or what?
You can hot air reflow both sides, the PCB keeps the components on the other side from getting too hot and re-melting and/or surface tension holds the components on if the solder does melt
I hot air both sides with this: ebay/stampabilities-heat-embossing-gun, about $20 - $22 from several places. Got my first BLF22DD's coming - just shipped from OSHPark today.
Thanks for the ideas, Tom E’s suggestion seems like the cheapest way, I wouldn’t have found that on my own. But I’m looking for an excuse to upgrade my soldering iron also, for a few dollars more than the Yihua 858D I’ve found a couple 2 in 1 units that seem to fit the bill.
I had bad luck with a bottom dollar hot-air / iron combo unit like that. It was an 852D+ clone marked as 952D or something. After <6mon the iron stopped heating consistently. I switched to the Hakko FX-888 for my iron and haven’t looked back.
IIRC I later learned that Aoyue was a decent brand among the cheap ones. I have no personal experience and I’m a little foggy on that, so I could be wrong.
I’m using a Yihua 937D iron with several different tips that works well now but read E5 on the display intermittently and wasn’t heating well. It turns out there was a cold joint in the wand and once fixed(the last time I used my old 20w pencil) I haven’t looked back. Not sure if I’ll go with air or oven first if I go reflow at all.
There’s all kinds of embossing guns and they can be found everywhere. Sounds like a plan. I sure am not going to pay anything more than a few bucks and that sounds like a cheap way. I’ve been using my soldering gun for everything. It works, but it would probably save time with this. Of course, I would have to switch to solder paste.
