... and the solder bridge between pin 53 and 54 should also be correct... since i did the same (except: i used a zero ohm resistor):

@sparkybg Hi，I just found two problems in the latest version firmware。I will chek on p.1, but p.2 is not a problem. Any action on buttons or encoder takes it out of sleep mode, and this is intentional, and it has always been this way.
1. C210 the really temperature is very low than set temperature，about 100 celsius。
2. when iron in sleep mode，press any key it will go holder temperture。
For p.1 - remove C85 and C86 on the back PCB if you installed them.

EAN: 8427327397798
Part no.: JBC-0016606
Cat. no.: 806839
I've searched for an elegant way to mount two of those to my soldering iron holder and decided to mount two of these cross bar holders:
... on the sides of my soldering iron holder, to put the JBC "forks" in. They fit almost perfectly... the one and only problem will be: i have to prevent the steel of the cross bar holders to directly touch the metall of my soldering iron holder. But it should be possible...

there is still no profile for nanotweezers.I'm confused. I thought there is one... according to the iron.c:
EDIT:
And, I've added NT115 (Nanotweezers) profile, but it is not tested.Oh... okay. I see now.
The resistors are given in the same table, and the connection might be like that on microtweezers, but I cannot tell for sure.I only did some testing with the NP105-A nanotweezers. They seem to work fine. Connections are indeed the same as with the microtweezers. Can't say for sure if it's the same with the NP115-A nanotweezers.

Hello sparkybg, when using JBC 245, without inserting the heating element, it displays "HEATER OPEN". When using JBC 210, without inserting the heating element, it displays "SENSOR OPEN". Is this normal?As 'sparkybg' said: it's normal. I assume it's related to the thermocouple being wired differently for both cartridges:

Is here anyne who uses the controller with a nano tweezer e.g. JBC AN115 ?I've recently bought the JBC NP105-A Nanotweezers. The wiring is exactly the same as with the Microtweezers (described by 'sparkybg' in the first post)... just with a different resistor of course.

And another solution is a small heatsink on each component, but we loose heatsink surface this way. This is pretty common for small FPGAs when they get hot. For example 10x10mm heatsink is not that rare thing to see. Although I never thought about their performance nor analysed it.There are some pure copper heatsink solutions which compensate the small mounting surface with their height and lots of flat fins. Like these (for example):
You don't see those kind of designs with all-aluminum heatsinks, since the material is too soft and brittle.
But i don't know much about their cooling performance either. I just used some tiny 6,5x6,5x12mm copper heatsinks for some mosfets in the past:
... which (as far as i remember) didn't perform as well as i was hoping they would.

What other method would there be to secure the heatsink?I used alumina/boron-nitride/epoxy-based 2k thermal glue in the past. With great success. I even dare to say: with too much success. Because i had a heatsink glued to an ADC ic in the past and the ADC failed and had to be replaced. Just out of couriosity i wanted to remove the heatsink. I tried brute force with a craft knife and even cranked my hot air soldering station up to 450°C in my attempt to remove it from the ic with lots of heat. All without any success
.So that kind of 2k thermal glue seems like a pretty reliable solution for mounting a heatsink... except when you are planing to remove the heatsink in the future

Did you try the last V1.33? My intention was to be used inside station case , as it is in mine case.Sorry... i did not try it. It's too big for my holder... and i did not want to add it inside the main case, since i wanted to maintain a kind of modular construction to be able to switch to a totally different holder with maybe an optical sensor... if a new tool needs one (i have at least 3 fully equipped and programmed optical sensor pcbs still laying around here somewhere).

Minkok, I have zero issues on 245 and 210 using 4001, I really believe it makes the cartridges last longer if you use the station daily.The initial design with the 4001 still works for me too. It's simple and very usable... even though i have the same behaviour lots of people had with (which is: touching the holder with my bare hands will be recognized as "iron-in-holder"... which i don't mind that much, since i usually do not touch the holder).
Can there be any improvements?
There is always room but this small PCB 4001 does the job for me.
But: this is a very (VERY) small pcb. And size does matter (in this case), because i don't have THAT much space inside my holder. I was planning to modify the pcb a bit (meaning: adding connections for a tiny angled connector... and holes for surface mounted threaded standoffs, to mount it easier and more elegantly to my holder - which is now done so far by two small nuts glued to the pcb). So if it's similar in size with a more reliable behaviour (due to software filtering) i'm all for a tiny PIC-controlled solution like 'sparkybg' suggested.

And even a simpler circuit can be made with the smallest PIC12/PIC16, but it have to be programmed, like my optical sensor. Hard reject on 50Hz noise can be done much simpler with software than with hardware. Then you will have 2 resistors, 2 diodes, 2 capacitors, a MCU, and that's all.Sounds good. I'm all for it

Even though i'm eager to try out the 1/8 power mode with my C105 i returned to the 02.12.2020 firmware... which was the last one working for me.

I also published new firmware with some corrections. Try it out.Sadly it doesn't change anything. It still always stucks at the holder temperature.
Let me see your pin53-pin54 and pin8-pin28 connections.I connected pins 53 and 54 via zero ohm resistor on the soldering pads for U9:
Pins 8 and 28 are connected via kynar wire:
I checked and double checked both connections with a multimeter - but they are fine. And there's no accidental connection to other pins either.
