experiments with lm561c

[rew]

I have been thinking about making my own knock off quantum board i have first made 2 small scale test boards to see how hard the smd soldering would be the first board wasn't the greatest soldering job in the world but the second one was ok i'm planing to make 2 150 watt panels so that would be a thousand leds witch by would cost around £160 just for the leds not he driver or pcb material however i'm not sure wether i should mix the 4000k and the 3000k leds and what ratio i should use do you guys think this is a good idea .

Eek! That's a good question!

Do you have reflow oven ?

I swear wtf. Just when you think you’ve got all the bases covered with this hobby, some shit comes out you’ve never fucking heard of lol

Surface mount technology requires the right kit and by the look of the soldering I don't think you have it.

Have a look at the kits on eBay, they are cheaper than everyone thinks

Don't think you could make from discrete components cheaper than that

BTW 3500 K is the sweet spot for veg and flower in binned 6 lm561c

well if that £227 pounds just for the board i could get the leds and the driver for that . i'm planning to use solder paste and my hot air station i agree the soldering doesn't look the greatest but that because i didn't use solder mask and to save printer ink i left a lot of copper areas and thats were a lot of excess solder flowed to because at the time i was using a rather large chisel bit which was a bit difficult to use

Look your soldering is as good as any, it's just you shouldnt hand solder smd chips

That kit is for everything
