No, the commonly understood terms within the industry are:

1) "Formed components" are those whose leads are formed prior to assembly. Examples are SMT QFPs and SOICs where the leads exit at the top of the body and are in frames, where prior to assembly the QFP requires excision from the frame and the leads are also formed into a gullwing shape. Another example is through-hole axial leads bent 90 degrees and trimmed, sometimes with a standoff bend, etc.

2) "Inserted components" are typically considered to be PTH components that are inserted into PTH holes and soldered, either by hand or by axial insertion machines along with selective or wave soldering.

3) "Embedded components" are those that are embedded into the PWB as part of the PWB fabrication process. Just about every smart phone and tablet utilizes embedded technology. There is more than one process for doing this; conductive-ink printed and subsequently laminated PWBs, or encapsulated, such as Joe (The Wizard) Fjelstad's  Verdant Occam process.

"Inserted Components" are fully functional components such as caps, resistors, etc. that can be inserted into boards.  "Formed" components are components that made as part of the PCB fab process.  Both inserted and formed components (mostly caps and resistors) are fairly common these days for many products (for example, just about every smart phone and tablet utilizes formed technology).  Inserted components were probably first used in the 1980s or early 1990s.  Formed components were first used the 1960s.

You need to define whether you mean inserted or formed as many PCB fabs utilize one technology but few offer both.

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.

Regards
GA Tan
