pro's for odd layer builds are few (to my knowledge),ie;
ability to add additional functions without the normal cost adders
associated with 4 layer, 6 layer etc.
potential for maintaining somewhat thinner profile over extra layers
con's outweight the above (again in my opinion);
built in warp and twist factor (added) due to weave of fibre
pulling/pushing against each other (odd layers tend to over power)
fall out rate due to excessive warp/twist possibility is greater (cost)
normal process of building the "book" for processing is different (operator
awareness)

Dear TechNet,
Can anyone give me pro's and con's for designing Odd number of Layer
PCB's i.e. 3 and 5 layer boards
