In my experience the current IPC test used by laminators to check dimensional 
stability has no correlation to dimensional stability results after multilayer 
lamination at a PCB shop.  Is IPC investigating a different test method or 
does any PCB shop have there own "dimensional check" for incoming laminate.  
I'm working on this issue at our facility and I'd like to swap ideas with 
other PCB shops.

Thanks in advance for any response.
