Al and/or Dianne, If you have a Hakko-style soldering pump similar to the Model 808, its nozzle (ordinarily used for desoldering) makes a great way to heat and apply solder to the varnished leads to remove varnish and tin them quickly.
Prior to using that technique (recently suggested on this reflector), I used a combination of candle or butane- lighter flame, fine-grit sandpaper and an occasional light coating of flux to get the job done to my satisfaction. Whatever method you adopt just be sure that the finished solder joints are completed with a proper "wet" look, and measure their resistance to the PCB board. Obviously, be sure to remove any residual traces of flux that may remain behind too. 73 Steve Banks K0PQ Sent via BlackBerry from T-Mobile -----Original Message----- From: "Al & Dianne Bruce" <[EMAIL PROTECTED]> Date: Tue, 6 Mar 2007 07:46:13 To:<[email protected]> Subject: [Elecraft] Tororids I'm having trouble tinning my toroid leads. In spite of rigorous cleaning they just don't want to accept solder ( Kester 44 ). Will adding some paste flux interfere with electrical qualities of the leads ? _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
