If I'm designing a 'normal' project, I use 0603 SMT components unless wattage requires me to go bigger. For smaller designs, I use 0402s and I've recently been forced to switch a few parts out to 0201s to make stuff fit.  I use an Amscope trinocular stereo microscope to work under and, even then, 0201 is truly the limit on what's possible in terms of hand-built prototyping.  Under such conditions, a small-tipped and tightly temperature-controlled iron is essential; such as my Hakko FX951.  Some designs go the other way with vias under high-wattage parts to sink heat to ground planes, these need high performance large irons such as the Aoyue 2900 with large tips.  I see the KSGER T12 and being biased towards the smaller end but I will wait until I get it and confirm.

Are you aware the Hakko T12 and T15 series 70w tips are the same as your Hakko FX-951 75W station uses? The clone T12 tips won't be any better than what you currently have.

Aliexpress says the Ksger is 75W (120W Max). 120W looks like a power supply maximum specification to me not the tip power consumption. I hope you're not expecting Pace and JBC performance after buying the Ksger. You are buying a cheap interface replacement with a smps.

I'd recommend Pace over the JBC. The Pace ADS200 is still fairly new so it's a case of getting the word out there till people realize the benefits. It doesn't have a fancy display, so if you weren't aware that Paces makes high performane stations you wouldn't know.
Analog:
If you are having difficulties due to thermal sinking try using a board warmer. Bringing up the board temp with hot air and then making the repair really helps. I don't believe it is possible to safety solder some boards otherwise. I have a $50 warmer that really helps out.
Gandalf_Sr:
Thanks all, I wasn't aware that the Hakko T15 tips were interchangable with the T12 tips.  My Hakko has an FM-2027 soldering iron which uses T15 series tips but changing the temperature is an absolute pain with having to insert the plastic thing and the do some form of ctl+alt+delete to change the settings!  Some commentators have said they prefer the KSGER to the Hakko for this reason alone.

I was aware of Pace and their high-end soldering gear and I have used the hot air rework station to preheat PCBs.

The batch issue was fixed straight away and that video is the early Pace firmware 1.2 which jumps all over the place.

I've seen that video before it's a bit of a joke if you ask me. Aside from the firmware changes that guy is using temp setback like an instant on switch. If the JBC was at 350C why was it delivering 37% power straight afterwards? It also lands on 350C so perfectly like magic. From what I've seen JBC has more aggressive heating profile. Less tip plating makes it appear more thermally responsive.

It's hard to draw exact comparisons for those reasons but I would say all things being equal it's closer that it looks. The Pace as of firmware 1.4 now displays and is set in single degrees, they also slightly improved the performance as well.
