Just out of curiosity Steve, what kind of oven are you using?

Subject: Re: [TN] Baking PLCC-68's...and emptying wave solder pots, an
epilogue.


Hi Dave!

We're not going to bake them in a reel, we don't have the time. We're
going to de-reel the parts and do the 48-hour, 125 C. bake.

I just got back from the store after buying some cookie sheets for the
parts since we didn't have any matrix trays that would fit a PLCC-68.

And before you ask, no, they weren't "Bakers Secret" cookie
trays...hehehe.

Finished up the wave solder job this morning, the pot is back full of
the shiney stuff, and I have two hold-down bolts sticking up out of the
solder, where yesterday there was only one. You can see them at:
http://www.stevezeva.homestead.com
look at; "New Hold Downs".


Kind regards,

Steve

Consider the material of the reel when selecting your bake temperature.
Baking at too warm a temperature will make the reel useable.
