We are a fab shop and on occasion we are asked by our CEM customers to
design carriers for boards they have received from other vendors or directly
from customers without the appropriate framework. 

 

Today we received a request to design carriers for the following flex
designs;

 

1.	0.005" thick, 3" x 3.5" 4-up array with 01005 components
2.	0.003" thick, 5" x 2" 8-up array with 0201 components

 

Now I doubt my ability to produce anything useful for these but you never
know.  At the very least, for my own knowledge, how does one go about
transporting these through printing, placement and reflow?  Are there
special universal carriers available?  Any suggestions or photo's of
something I can whip together for our customer?

 

Regards

 

John Parsons
