Will Embedded Passive Components Obsolete Surface Mounted Passives?

Embedded passive components are buried within the PCB substrate during fabrication. They can offer benefits such as lower costs, improved electrical performance, increased packaging density, less parasitic losses, less cross talk, improved signal transmission, and more.

 

Here's the question: Will Embedded Passives Components Obsolete Surface Mounted Passives?

Parents

  • The chemistry of making fibreglass/copper pcbs is not compatible with that for making semiconductors or most passive components - so you might end up embedding small, pre-tested and manufactured parts in the pcb. For most applications this sounds like increased cost and additional problems for very little gain.

    There may be special applications where there is a big performance advantage and it may happen there.

    Current applications are mainly chip on board (for low cost, low reliability) or very low grade resistors for mass production.
