SMT Plus has a good selection of reflow pads but no wave patterns (7th
edition). Their pattern book costs $300.00. I can recommend their "SMT
Design Rules and Standards" book instead, for formulating wave patterns. I
have heard many reservations about IPC's patterns from other designers so
use caution. No matter what, trust no one completely. Do coupon tests for
your processes.

Can anyone help:
We currently design predominantly single sided pcbs with surface
mount componets wave solded.
Our footprint designs are based on Siemens recommended sizes for
805,1206 & sot23.
We are about to review our footprint designs can any one recommend
from their past experieces some footprint designs.
With thanks
