I am embarrassed to have to ask this, because I know it has been
discussed before, but I have a question about replacing MIL standard
references with commercial standards.
Our default fabrication drawing notes always say (whatever specific)
material "per MIL-P-13949". Is that common these days? Is there a better
replacement for material if our designs are commercial only? Does it
even matter?
I looked at the IPC stuff and there is a whole series of IPC-L-XXX
specs, but I wouldn't even know what is appropriate.
I thought I had a web link to a "comparison" kind of service, but can't
find it (I've just discovered that many links I have been saving for a
special occasion like this, no longer work! d'oh!)
On a more broad-scale issue: Are any of you fabrication vendors out
there willing to share what you like to see on a fab dwg regarding
notes? For many of us, we just want a good product and don't really care
what the notes say, we just put whatever we think you need to see....
What do you need to see, MINIMUM?
material, finish, mask, & legend
quality per ipc-rb-275 for type x class x
is that enough? jack
