Embedded Component Design Best Practice

With increased market demands for smaller and lighter products, improved performance and
higher speeds, it may become necessary to consider the embedding of passive or even active
components within the inner substrates of the PCB. If you are designing product that essentially
can be held in your hand, perhaps ones used in mobile applications or a consumer electronic
device like a digital camera, embedded component technology may be in your product roadmap
plans.

This chapter covers the best practices for embedded component design using the Allegro
PCB Editor. It may or may not be closely linked to the processes used by the fabricator you partner
with. It is likely that your fabricator has patented a process for embedded component
manufacturing. The methods on how components are mounted and logically connected to the
formation of cavities may differ from vendor to vendor. As always, the best advice for advanced
PCB Design whether that be HDI, Flex or Embedded is to work closely with the fabricator who may
own the Allegro layout design tools. They can advise on the proper parameter and constraint
settings that best accommodate their process flow.
