IPC 610 *C* states that the solder thickness requirement is a properly wetted termination is evident. Fillet height is another aspect and is usually specific to the package but is some function of solder thickness plus a percentage of lead height. D

Mike, dude, I feel your pain. Hearing stories like this makes my blood boil! It's almost as ridiculous as a customer who told me to put more solder paste on a MELF component to overcome noise issues - he used more solder paste as antennas to overco

I'm sorry, Dave - I didn't make myself very clear. Yes, this space (not really a "gap") is filled with solid solder. For instance, if you place a gull-wing component in solder paste, after reflow, there will probably be a thin film of solidied solder

We don't have a gap between the lead and the pad after a SM joint is soldered. On our boards, this space is filled with the solder intended to attach the component to the board. How high do components sit above the surface of a board? Most people a

Maybe ask your customer where they got this idea from? It is possible they may have even got this idea from some white paper or article where they are trying to explain something else and show drawings with no solder between the pad and lead. It may

This phenomenon is caused by a high amount of halogens (Cl, Br etc.) used in the flux activators or in the flux surfactants. We've seen effects creating all colors of the rainbow. Changing to No-Clean (halide-free) will eliminate this color effect.

Patrick told you why, But here is some more info for ya, I would absolutely not recommend that wires be tinned with OA. The residue will never get cleaned underneath the insulation and all of your strands will strt to break in the near/far future.
