What is a MIS (Molded Interconnect Substrate)?

A Molded Interconnect Substrate (MIS) is a specialized technology used in electronic packaging and circuit integration. It combines the functionalities of both a printed circuit board (PCB) and a plastic injection-molded component. MIS allows for the integration of electronic circuits directly into a molded plastic structure, enabling smaller form factors, reduced weight, and enhanced design flexibility compared to traditional PCBs.

In MIS, conductive traces are directly formed on the surface of the molded substrate, typically using processes like laser ablation, plating, or conductive ink deposition. This eliminates the need for separate wiring and soldering, reducing assembly time and cost. Additionally, components such as resistors, capacitors, and even integrated circuits (ICs) can be embedded within the substrate, further enhancing miniaturization and simplifying assembly.

MIS finds applications in various industries, including consumer electronics, automotive, medical devices, and wearable technology. Its benefits in terms of size, weight, and design freedom make it particularly suitable for products where space constraints and aesthetics are critical considerations. However, the design and manufacturing of MIS can be more complex than traditional PCBs, requiring specialized expertise and equipment.

What are the MIS Design Guidelines?

The design guidelines for Molded Interconnect Substrates (MIS) typically include the following aspects:

  1. Substrate Material Selection: Choose a substrate material suitable for the molding process, typically high-temperature-resistant plastics such as polyimide (PI) or polyamide (PA).
  2. Conductive Path Design: Design conductive paths considering signal transmission, power dissipation, and circuit layout to ensure good electrical performance and signal integrity.
  3. Dimensions and Layout: Optimize dimensions and layout to meet the product’s space constraints and design requirements, considering component placement, orientation, and connectivity.
  4. Component Embedding and Wiring: Determine components that need embedding into the substrate, design appropriate embedding methods, and wiring plans to ensure smooth connectivity and circuit paths.
  5. Packaging and Protection: Select suitable packaging materials and methods to protect the circuit from environmental factors such as humidity, temperature, and mechanical stress.
  6. Manufacturability: Consider the manufacturability of the design, including the feasibility of the molding process, process tolerances, and cost-effectiveness.
  7. Testing and Validation:Plan testing and validation processes to ensure the design meets specification requirements, and perform necessary revisions and optimizations.

These guidelines help engineers and designers formulate appropriate design strategies for MIS projects, ensuring the performance, reliability, and production efficiency of the final product.

What is the MIS Fabrication Process?

The fabrication process for Molded Interconnect Substrates (MIS) typically involves several key steps:

  1. Substrate Preparation: The process begins with preparing the substrate material, which is usually a thermoplastic polymer such as polyimide (PI) or polyamide (PA). The substrate may be in the form of sheets or pre-molded structures depending on the specific requirements of the design.
  2. Surface Preparation: The surface of the substrate is prepared for circuit patterning. This may involve cleaning, surface treatment, and application of adhesion promoters to ensure proper adhesion of the conductive traces.
  3. Circuit Patterning: Conductive traces are patterned onto the substrate surface using techniques such as laser ablation, screen printing, or photolithography. This step defines the electrical pathways and interconnections of the circuit.
  4. Plating: After patterning, the substrate may undergo a plating process to enhance the conductivity and durability of the conductive traces. This involves depositing a thin layer of metal, such as copper, onto the substrate surface.
  5. Component Embedding: Components such as resistors, capacitors, and integrated circuits (ICs) may be embedded directly into the substrate during the molding process. This integration reduces the need for separate components and simplifies assembly.
  6. Molding: The substrate with the patterned conductive traces and embedded components is then placed into a mold cavity. Molten thermoplastic material is injected into the mold, encapsulating the substrate and forming the final molded structure.
  7. Curing and Cooling: The molded substrate undergoes a curing process to solidify the thermoplastic material and bond it to the conductive traces. After curing, the substrate is cooled to room temperature.
  8. Post-Processing: After molding, additional processes such as laser trimming, surface finishing, and inspection may be performed to ensure the final MIS meets quality and performance requirements.
  9. Testing and Validation: The finished MIS undergoes rigorous testing and validation to verify its electrical performance, mechanical integrity, and reliability.

Overall, the fabrication process for MIS combines aspects of traditional printed circuit board (PCB) manufacturing with plastic injection molding techniques, enabling the integration of electronic circuits into complex three-dimensional structures with high precision and reliability.
