The complexity and density of electronics design has increased, partly due to the rise of the mobile industry, introducing new challenges for printed-circuit board (PCB) designers. Embedding components within the board substrate offers a practical solution to several issues, and it’s quickly becoming a feasible production step for fabricators.
Why embed components? Before discussing the methods for adding embedded components to a design, it is important to understand some of the advantages they offer. One must consider all the benefits and drawbacks of adding fabrication steps before starting the design, in addition to the potential effects on cost and production yield.
Reductions in size and cost drive innovation in PCB technology. Embedding components can help reduce the size of the board assembly. It also can potentially reduce the manufacturing cost for complex products.
Minimizing electrical path lengths to reduce parasitic effects is critical when dealing with high-frequency circuits. Reducing the wiring length of passive components to an IC can decrease parasitic capacitance and inductance, reducing load fluctuations and noise within the system. By embedding passive components, it’s possible to position them directly underneath the pin of an IC, minimizing potential negative effects, including via inductance.
Minimizing wiring length to an IC is a common solution for reducing parasitic effects and improving device performance. Embedding components in the board substrate (top) allows for additional wire length reduction over surface-mounting (bottom).
An integrated electromagnetic interference (EMI) shield can be manufactured directly around an embedded IC. Simply adding plated through-holes surrounding the IC can reduce capacitively and inductively coupled noise. It also can eliminate the need for an additional surface-mounted shield in certain applications.
Heat-conducting structures can be added to an embedded component easily, improving thermal management. One such example would be to embed thermal microvias in direct contact with an embedded component, allowing heat to dissipate to a thermal plane layer. Additionally, reducing the amount of PCB substrate that heat must travel through reduces thermal resistance.
Long-term reliability is a major source of difficulty and concern when implementing embedded components in a design. The sustainability of solder joints, when placed within the laminate framework of a PCB, is affected by subsequent soldering processes, such as reflow on surface-mount devices. Embedded components can cause additional problems after manufacturing, since they cannot be easily tested or replaced following a failure.
