Steve,
If you don't want to be tempted by the excess calories, donate them to 
your local food bank. 

I like Graham Collins explanations and agree with his view of not cleaning 
these.  I have looked over a lot of vendor data sheets on whether the 
components can withstand "Process X".  There are always weasel words in 
there that say "test them and see".  And when you ask their technical 
support, it is "test them and then let us know how they worked".

I am really not a fan of water-only cleaning.  I have never seen it work 
as it should.  The addition of small amounts of detergents or surfactants 
are really needed for the low standoff parts we are using these days.

Hi All,

 

First Halloween in Boise last night, and made the mistake of buying
candy for the goblins that would be knocking on the door. As you might
have guessed, I didn't have one trick-or-treater stop by. So now I'm
stuck with three pounds of candy. Maybe next year I should put out signs
or something, or just not buy any candy at all. But if I didn't buy
candy, I probably would be inundated with trick-or-treaters huh?

 

We're going to be building a board that contains a Rotary Potentiometer
from Vishay (PN# P11A1F0GHSW10502KA). It's a through-hole potentiometer
that I've never personally seen.

 

I've looked at the datasheet (http://www.vishay.com/docs/51031/p11.pdf)
to determine whether or not it can be cleaned after wave solder, and it
really doesn't say other than to say that it's IP64 sealed. What does
IP64 sealed mean?

 

I must have sent 3-4 emails over the past week to Vishay support asking
the question, and haven't heard a peep. Certainly can't speak to anyone
over the phone.

 

Does anybody know if I can do an aqueous clean (straight DI, no
chemistry) on this?

 

Steve
