Reply to "New Hakko Digital Solder Iron and FET"

I'd like to thank everyone who contributed to this post. The tips and suggestions gave me the confidence to proceed with the replacement of the FETs on my slave board.

I set the temp of the FX 888D to 700 degrees, cut the 2 legs on each FET, heated the heatsink and used tweezers to remove when loose, then heated the remaining pieces of the legs and removed them.

I then used no clean gel soldering flux to stick the new FET's in posiition while I held it down with tweezers and soldered the legs. I finished up by using 37/63 solder on the heatsink allowing it to flow around and wick in.

When placed on the track & connected to the A & B units it performed perfectly.

Thanks again,

I really appreciate the help,

Ron
