Thanks for your kind recommendation Bob
 
 
Hi John
 
For your specific questions the 3rd edition addendum, which  has an updated 
chapter of flex assembly which was graciously attended to  and very nicely 
executed by Bob, is likely best for your present  interest. 
 
www.flexiblecircuittechnology.com
 
Happy's book is available at:
 
www.hdihandbook.com
 
There is as well another free book that should be of interest by  Steve 
Williams of Plexus

Best wishes, 
Joe

If you  download a copy of Joe Fjelstad's latest book Flexible Circuit
Technology  after you do a Google search it features a section on flexible
assembly and  a number of pallet option images.

Just like the HDI book by Happy its  free and should be on everyone book
shelf.

Many  thanks

Subject:  [TN] Flex Carrier?

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
