Jim,

Sorry for not explaining.  The Pad Prep Pen is used for rework, particularly with our hot air rework station.  When removing the component, flux is applied to the leads.  After component removal, the flux residues are then cleaned off the pads, to prepare the pads for soldering the new component to the board.

Howard:

I can't help asking: why do you remove no clean flux residues?

Jim,

Interesting that you ask, as I was just in the process of ordering some more of the pens that we use, which is called a "Pad Prep Pen", made by A.P.E. , P/N is 8200-1350, 8 for $89.  I don't have experience with any others, so I won't place judgement.  However, our operators love this one for removing our no-clean flux residue.

Good afternoon,
 
I was informed by my purchasing department that Multicore (part # MC-PV-01) is no longer making their Mini-cleaner (prozone pen), that we were using to remove flux residue from hand soldered applications.  We have received a sample from a different supplier that is supposed to do the same thing, the only problem is the pen leaks severely when you push on the tip.  This may be a bad sample, but we are not off to a good start trying to find a replacement.  Does anyone else out there use these types of pens to remove flux residue from hand soldering or similar applications?  If so, what manufacturer do you use and how do the pens perform?  You can email me off-line if you like.
 
Thanks,
Jim West
