assume a perfect friction fit between a round smooth pin and a plated hole each with +-0 tolerance how much allowance, minimum, should be given to allow minimum solder wicking vertically along the pin and down the barrel? just the annular amount for the solder itself in a perfect world i could not seem to find info on this, additional real world variables would be accounted and allowed for afterwards i realize there are solders and there are solders and probably soldering temperatures involved but just a starting point number would be interesting for the issue at hand thx
