Hey John: Chrys wrote a good description on calculating flux density a while back. Here is our version of her procedure: 4.3 Determine the amount of flux on the board. 4.3.1 Get a piece of corrugated cardboard and a weighing scale accurate to 0.01

Hi Dave, that was kind of a more rhetorical question. Normally paste is used before shelflife expires and delivery time is short enough to get in no trouble. The normal situation is that you try to get your equipment running means constant use of pas

Mike, Russ is right, no 'normal' wave machine will solder PCB's with 1" long lead length. I have seen waves modified to clear up to 5/8" leads, but the deeper the wave the uglier things get. They get uglier in that a lot more dross is produced, con

Apologies to all who go beezerk (I'm one) when some maroon dredges-up an old thread (usually so they can babble in some thinly 'gised advert). I'm not doing that. I go more beezerk when we let someone's quiry go unanswered. Anyhow ... Francis: A

I am a Siemens person myself but you won't get 23", you can get 20 though and I believe you could feed in a 23" board length wise. If your parts fit in a 20" area 80F4 is the way I would go. My second choice would be MYdata. They are the large board

You appear to have two problems working against you at once. One is component lead corrosion that the no clean flux isn't aggressive enough to remove. Do a simple dip and look test. Flux the leads of a component and dip it into the molten solder for
