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.
I have this hotplate https://www.aliexpress.com/item/UYUE-946-1010-LED-Display-Preheating-Platform-for-Mobile-Phone-Repair-220V-110V/32954192636.html
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.
Sure, I’ll take 8 of the 3000k if its not too late… I haven’t signed up for any of them yet I dont think…
No prob. You weren’t added to the list.

Anybody else?
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.
Thanks. So 3500K 3000K can be shipped with springs.and 4000k will be later.
Then I am in for 20pcs 3500K and 20pcs 3000. and no 4000K if possible.
Excellent.
I’ve added you all to the updated list:

If I actually manage to find a good source of 500 SST-20 4000k, then we are golden
Dang Blue! I finished a ROT66 LED swap to your 3500K's from the 219B's and am very happy with it. Kcd is up 50% and got a slight bump in lumens as well, and really like the tint! Side by side with an E07 with their SST-20 4000K's and it's quite a difference - the 3500K's got that rosy touch while the 4000K's seam to have an something like an aqua blue. I thought the E07 looked really good before this side by side comparison.
Thanks Again!!
Other notes: swapped the stock teflon short LED wires with silicone 18 AWG longer ones to allow re-programming, and removed the inner spring of the driver spring and added in a short 22 AWG bypass. I left the dual springs in the carrier as-is for now.
