The printed circuit have become much much complex than it is around 15 years ago because of the huge BGA chips and various other signal integrity recommendations that needs to be followed. So may be the inexpensive passives are not an worry to the design houses. If the passives have to embedded all the OEM's need a specific engineers to take care of the effects of it. So we won't see embedded passives in the PCB's.
Embedded passives are a great idea, however a couple challenges I can quickly think of would be trying to perfect the values of the embedded passives during the design process, and having high tolerances on the board materials in order to get the right values. Also, if there are any manufacturing issues on the PWB's, it would be very hard or impossible to fix on built up PWBs and they would need to be discarded.
Implementating embedding passives should be a technique adopted which will free up the space on the top surface, in turn all other active components can be placed. Especially this can be used in small devices.
Suppose if we can place capacitor dielectric between ground and power this will become a good filter and also we can connect the capacitor near the active component there by will reduce the number of layers.
"Their conclusion was that embedding passives into the board would save some amount of cost for resistors and capacitors"
Embeddeding passives will results in higher cost (per unit area) of boards fabricated with embedded passives and possible decreases in throughput of the board fabrication process. Do you still feel this will save cost ?
It has been come imperative for future electronic design products to face with huge challenges due to an increase in their market demand. So also, while this is about to happen we cant rule out for less expensive functionable materials to integrate to the design board.
1 - If embedded passive elements could be the determining factor for a) optimum component performance b) technical processing c) cost effective ie less expensive i could not see why the design engineers should shirk away from adopting more responsibilities.
2 - Leakage: If concerns about the power leakage could also be brought to a considerable level by developing with high -K materials so as to improve battery consumption, i think it could be worthwhile taking up the challenges with embedded passives.

Peter Drucker famously said "Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window." Yet in the razor's-edge world of electronics—with a lean supply chain and just-in-time demands—the need to know the future is vital.
While no one really can accurately predict the future, we can take guidance from another Drucker saying which is the best way to predict the future is to create it.
You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically.
Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions?
Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
