content: I've beenfor a decent iron that will solder heat sinks to ground planes.found this video demo, check this out for awesome heat maintenance.I would say heat 'recovery' but , recovery is for an iron that cant take a beating.This one seems to just stay hot.what do you think?

content: That's because their temperature control is set very aggressively.Notice the large overshoot in temperature after the thermal load is removed?I'd say this is fairly equal to my Ersa i-Con stations.

content: Looks like the temp is set to 400+'C, that's the element temperature,looking at the size of the bit, very small thermal mass. Your probably assuming it's cold water, maybe just below boiling, will never know, heat loss may just be from the very tip, it's hard to see how far into the water ( if it is water ) the tip is being inserted.Try this for how much a tip can drop when placed on a wet cleaning sponge

content: That's probably got to do with the recovery time of his station due to many parameters (HW/FW)My station recovers quite quickly and well ... his DIY station is really slow

content: Quote from: Mr Smiley on December 07, 2012, 06:34:58 pmthanks mr.smileyThe other day a bought a 60w soldering iron, I would dip the tip on a wet sponge and i could then place the tip on my finger!! Yet the temperature would say 450 degrees Cthis is why my heat sinks on a ground plane were near impossible to solder ( unless i heat the board in the oven for 10 mins but then its hot to handle.)someone on eevblog pointed this iron out a 'quick 203h'http://www.mrtechservices.co.uk/product.php/31/29/quick_203h_90w_digital_soldering_stationit claims to have its sensor near the tip , no one else seems to claim this!surly this is one of the most important aspects of an iron? more than wattage?so my thoughts now are to either buy a150watt xytronic - usa soldering stationor90watt quick 203h with the sensor near the tip?people say weller are the best ? i wonder where a weller sensor is?lots for me to google . lol.

content: Leidenfrost Effect significantly slows the cooling of the iron tip. Kind of like dipping a finger in cryogenic liquids. I quick dip doesn't reduce a persons ability to count.

content: If you dip your soldering iron on a sponge and it drops 100°C then there are a few possible problems:-Shit soldering iron-Sponge is soaking wet and not damp as it should be-shit control loop-super tiny tip with low wattage iron

content: The guy in the video link i posted had drilled the very tip of his bit and inserted a thermocouple probe. This was to compare the core heater temperature response to external factors, ie the wet sponge.

content: I have a Weller WESD51 for general board soldering and a vintage Weller WTCPN Soldering Station for most larger jobs. Not easy to find one station that will do everything correctly. I sometimes even use a Weller 150/200 watt gun for big stuff like soldering directly to a chassis. The old Weller WTCPN station is used the most but that's due to the fact that I work on mostly vintage equipment. These newer little stations are nice for board and surface mount work but really don't have the balls needed when it comes to the larger jobs on older equipment.

content: Quote from: harps on December 08, 2012, 02:47:50 amOnly $384.00 from Janel if you are in the US. Trust me, worth every penny if its in your budget.This is the one I used in the videowide tip was not included. Watch the tip change video and the time for the tip to get to temp.

content: Quote from: necroscope on December 07, 2012, 10:15:42 pmI had Pace HW50, its not as fast as JBC. Pace needs about 6-7 seconds to heat up while JBC does it for 2-3 seconds, this really plays a role when reworking multilayer boards.Pace is also amazing quality and tips last forever as with JBC.
