Steve, Let me try to give you a short answer to your question. A good book in soft soldering would talk about the excellent characteristics of leaded alloys and all the reasons why leaded alloys are very reliable. In short a good book would advice y

Wave solder - Initially high cost but after that it is relatively cheap. Selective soldering with a solder pot such as the Air-Vac PCBRM models - Much lower cost than wave but if you get the right nozzles it is a great process. Solder preforms - s

Hi Grant, You already have a few good answers. If you have but one to a few BNC connectors I would kind of use the advice here or do what you already are doing aka hand soldering. I would not install a Wave Solder line for a really low volume of BN

Collapsing of micro bga ball due to improper land pad design ?
