I had the advantage of a quick "course" on surface-mount installation by a sales rep for a soldering-iron company! The secret to installing the things is to use a flux-pen and coat all the legs and pads with flux. Excess solder then just runs off and doesn't tend to "stick" between the legs. The final trick is to use an iron with a concave bit, I think Weller now do one, this draws solder into its dimple and, in conjunction with the flux, makes it easy to clean away solder bridges. You just run the tinned iron along the row of pins and Bob's yer uncle! Well... if your lucky! I still spent a long time with a powerful magnifying glass, checking every pin. 73. Dave G3YXM.
