I just de soldered the wires on the speed control .The solder must have been a hi temp. solder ,,I had to use my pencil torch any Idea what kind of solder it is and where can I get some thanks chris

It could be silver solder.I have some from the LHS and it needs alot more heat to melt and flow than the 60/40 I normally use. -
Might just be that your iron was not up to temperature for the mass involved. High tin solder content melts at a lower temperature then a greater lead content but a higher lead content does not suffer the issues when using the higher content of tin. Using a Rohs complaint solder is just plain stupid. 40/60 melts at 460 deg F and thats about as strong a bond you need with electronic components.

Something people very often overlook is that the soldering tip must be kept clean and flat. This is why most soldering stations include a sponge. Using a wet sponge or even a paper towel regularly makes a huge difference. When the tip becomes pitted, put on a new tip or use some light sandpaper to clean it up.
When you use a dirty/pitted tip, you will heat up the entire circuit before you accomplish the task, which is dangerous for the circuit, on top of the frustration it gives you.Comment

You might have an ESC that was manufactured by a company that is now adopting ROHS compliant methods. Europe has tried, and so far not been very successfully, at forcing companies to adopt lead free polices in manufacturing. The idea being land fill issues with contaminants such as heavy metals. This in itself is not a bad thing. We should be indeed responsible for the quality of our environment thru better safeguards and adopting practices to ensure minimal contamination of the land the water we drink.
What Europe did was jump the band wagon. In trying to be kinder to the beast of burden (their intent) they decided to leap ahead of the cart and proceeded to drag the horse along by the reigns and killed the very animal they sought to protect.
Now your thinking what the heck has that got to do with the solder on my ESC melts no at a higher temp? Well,...........I had to get your attention even if it was thru a form of boredom, should you recover.
Some companies are now using a tin-silver-copper solder mixture that melts at 227 dec C (440 deg F) in the name of being ROHS compliant. But that solder is sort of spendy so there are cheaper Eutectic Solders like Indalloy in various grades that will melt at temperatures up to 800 deg F.
What I am saying is it sounds like your ESC has some form of newer solder alloy and sorry about the long winded with my explanation but thought it might help to add some details in case folks start asking well can I mix my 60/40 solder with this newer stuff. The answer is no you cannot depending on what type the manufacturer used initialy.

How many watts is your soldering gun? I've messed around with cheap soldering guns for years, but recently bought a quality soldering station. I'll never go back.
