Hi GA Tan-

The question is what you mean by "discrete". For most people it means a
passive which "stands on its own" as opposed to something done with special
dielectrics and/or resistive metal layers to create passives within a
circuit board.

For the embedding of truly discrete components, this is Joe Fjelstad's
special area. He had a shop build a demo circuit. His website covering the
technology is www.verdantelectronics.com

The tricky part is how to electrically connect to the passives. Probably a
laser could be used to dig down to the part and then plate up a contact. But
most end terminations are covered with Sn, which is particularly difficult
to make contact to (other than with solder).

For the other technique, using special foils and/or dielectrics, there are a
few competing products. They all seem to substantially increase the number
of steps required to make a board, and they are so volume-inefficient that
there are only a small number of cases where they work out economically.

Dear All,
               I'm looking for PCB supplier who has the above capability for
proto design. Any recommendation? Thank in advance.
