The entire switch/PCB assembly is potted in white epoxy material.

There is no way to fix it.

The replacement switch/PCB assembly costs $85 US.

A new tool without the battery is $105 US.

   I've opened up and repaired dozens of wall warts and other devices that clearly stated "Do Not Open, No User Replaceable Parts Inside" (or word to that affect) and found that the only fault was that a standard glass fuse was blown!  Normally, the wall warts aren't available from the manufacturers so that means that the entire device is intended to be discarded and replaced.

   There's no excuse, other than greed, for this type of BS from equipment manufacturers.   Environmental issues alone should dictate that manufacturers provide at least a minimal amount of support (schematics?) and cease misleading customers into discarding easily repairable electronics devices and filling land fills with them.

I would guess because, apart from epoxy have better moisture resistance and other things that a previous poster mentioned, it's also a helluva lot cheaper than silicone potting compound.

The "no user-serviceable parts inside" verbiage is a UL requirement. An internal fuse can have exposed hazardous voltages, so it is not user-serviceable. It can be replaced by a trained technician such as yourself, because you are expected to know to unplug it first; the average Joe on the street isn't.

One would believe that a soldering station manufacture would support the repair of their equipment. One of the excuses they gave was techs dont have the skill do go component level repairs hahaha cannot make this stuff up.. I will try and go thru my recordings some day and get the clip.

Anyways, I am sure the law firm of Squire Patton Boggs will be making some good money off this. at at lest Hakko's attorney Dennis Oyakawa will have a good year.
