Hi, Technetter!
    Now our CAD engineers only build one set of pads library for reflow.
But the PCBA  often need to go thru reflow & wave soldering due to mix
technology. There are some soldering issues for reflow pads at wave
soldering. Then we require CAD engineers to build 2 sets of pads library
in Cadence: one for reflow and another for wave soldering. But the CAD
engineers said it is no use for they don't know whether the component is
at reflow side or wave soldering side when they select pads from pad
library.
How to solve the problem? Is any good solution or advice?
Thanks in advance!
Davis
