a little trick i use is to flux a whole row of pins…..line the part up and tack solder two opposing corners to line things up….then run a bead along the whole row WITH THE PCB TILTED ALMOST VERTICAL and almost upside down….let gravity do the work…
start at the top of the row…add solder and run the tip down the row……gravity helps wick the fresh solder away as you go and leaves an almost perfect job……flux and fresh solder is the trick……Gravity works wonders….
with a little practice you can do perfect joints leaving just enough solder on each pin that you cannot tell if a machine did it or you…….Gravity, fresh flux, fresh solder and a continuous movement down the whole row……
if you want to use the hot plate….pre tin the pads with plenty of flux and fresh solder first ……then apply your paste….. ? ?hot plate it….then reflux and use gravity wick off the excess

Can anyone direct me to a supplier for smt IC
templates that is reasonable?? I found one supplier but they
wanted $80 for a small SOIC8 template.? I know that if I order pc
boards from a Chinese board house I can then add a project
soldering template to the order for $10 but I am looking for just
the IC templates.? I can usually hand solder the other parts but
when I get to a QFP144 or QFP64 IC I can't hand solder it.? My
Weller WCTP soldering station does not have the option of buying a
solder cup tip to use for drag soldering like a Hakko or Pace
offers.? For that reason I was hoping that someone makes and sells
just the IC footprint templates to allow me to use solder paste
and a hot plate and hot air gun or reflow oven to mount the
chip(s).
Thank you.
