Yep. That’s a relatively recent botch on my part though.
The light brown/orange stuff was some flux from experimentation trying to solder my springs with a hotplate. Ended up buying a heatgun after that.
The dark brown stuff is metallic copper sludge remnants(Cu3+), an oxide. I literally can’t remove it…

BlueSwordM: Please could you add 10no SST-20 4k & 10no LH351D 4k, in addition to the springs on line 19 of the s/sheet?

Hhhmm. Guess the 100x100 size would be good enough to do least a few 17 mm drivers at a time, and can handle the biggest drivers or MCPCB's. The shipping cost is big though. I like they can go up to 200C, better than 212F (100C) max of the burners.

Good price w/shipping, not much info on it - do you know the max temp? Hoping for 200C or better.
Found other listings that say 50-350 or 50-400 -- that's good, assuming in C!

I have used it at around 200-220C but I think the max temp is 400C.
In a few hours, when I return to my home I check it.

So how do you like that hotplate? It looks very small and convenient, I almost bought one. What time does it take to reach the set temperature?

@BlueSwordM , could you please reduce my query to 10 * SST20 4000/3000 (springs and 3500 K are without change)?

Confirmed. Maximum 400C.
I like very much. Since I have it, I have not failed any led reflow.
Room temperature 27C (air conditioned).
Hotplate initial temperature 33C.
Delay until reaching the set temperature (218C) 10:44 minutes.

Thanks, I have been thinking about this unit for several months, you just convinced me - ordered

It's the best price as well on Ali. Others may list it cheaper but charge almost as much for shipping.

BTW guys, I’m going to order the 3000k LEDs at the same time as the springs.
Who would like additional 3000k LEDs?
If I could actually order 250 LEDs, I could actually make them a bit cheaper than 1,50$USD/pcs.
I’m also still looking at the SST-20 4000k.

BlueSwordM, add 20 of the SST-20 3000k to my order (line 47) if that helps.

What is the current price of 3000K with fee ? Is it cheaper than at intloutdoor?

Currently?
If you order with the springs, yes.
Otherwise, since you pay for shipping, it’s not really worth it if you buy a small quantity of LEDs.
So, in your case, since you have some springs, then yes, it will cheaper, even with the fee, compared to Intl Outdoor.
