I'm working on some boards that have a 0.5mm pitch mezzanine connector and I just can't seem to get the kind of result I need. The connector consistently is getting solder bridges back under the plastic. So I'm thinking the only way to defeat this is to increase my technique to using reflow. I have a hot air pencil, and it is almost working well but I need a lot more heat which means the tool is a lot closer and means the chances of spraying solder under the connector increases. What I'm thinking is that I need a board heater to reduce the amount of heat needed from the upper side so I'm looking at adding the Aoyue 853A preheater and wondering if anyone had comments on it.
