Can anyone recommend good soldering technique for
hand assembly of 20mil pitch devices and 0603, 0402
SMT chips? We are looking at doing some protoype
assembly on some fairly dense (and small) pcbs. We
were thinking of using solderpaste and one of those
portable solder pens with a hot air tip ie. Weller
Portasol.  Has anyone had success using this
technique?
Thanks
Ron.
