I use a cup warmer and a steel cup to hold my parts for 24hrs.... more or less .... I just plan it out to do my hand soldering the next day .... I plan in the future to use a toaster oven to do soldering and preheat for repairs ....
oh... I have 2 soap stone boards - 10" wide by 14" long - to maintain constant temp, don't know yet if I really need them but I know soapstone holds heat well...
still need a digital controller for the heating elements .... plans....plans .... plans.

Subject: RE: [Homebrew_PCBs] Baking LEDs
Some electronic components can absorb humidity and when going through the
thermal soldering cycle the humidity can expand and cause microscopic cracks
that later allows more humidly to get in and possibly degrade internal
circuits.
Baking is a common requirement for some complex ICs but I have not seen it
for LEDs. For non-military-medical ... applications I would not worry about
it for hobby use.

Hello,
I am very new in the world of DIY PCBs. As a basic example, I'm going to
make a very simple LED circuit. I've ordered up some SMD LEDs and matching
current-limiting resistor.
The interesting thing is that the bag the LEDs came in had a label
indicating that I should bake them. I did a quick search, and found one set
of instructions indicating baking at 80 degrees C for 24 hours.
I know that this is not really specific to construction of the PCB, but I
thought one of you might be able to help me. How do you guys handle this?
Toaster oven? Or is there some kind of small oven that I can buy? What do I
put the LEDs on when I bake them? A baking sheet? Sorry for being obtuse - I
just really don't know where to start.
Thank you for the help.
James
