What is a Molded Interconnect Substrate?

A Molded Interconnect Substrate (MIS) is a type of substrate used in electronics manufacturing, particularly in the production of compact and lightweight electronic devices. MIS integrates both the structural and electrical functions into a single molded component, typically made from a thermoplastic material like polycarbonate or liquid crystal polymer.

The MIS process involves creating conductive traces, vias, and other electronic features directly onto the substrate material. This is achieved through various methods such as laser ablation, metal deposition, or printing conductive inks. These features are then embedded or encapsulated within the substrate material through a molding process, forming a robust and compact structure.

One of the key advantages of MIS is its ability to reduce the size and weight of electronic devices while also simplifying the manufacturing process by eliminating the need for separate components like printed circuit boards (PCBs). Additionally, MIS can offer improved electrical performance and reliability due to shorter interconnect lengths and reduced parasitic effects.

MIS technology finds applications in a wide range of industries including consumer electronics, automotive, medical devices, and wearable technology, where space-saving and lightweight designs are critical. It enables the production of smaller, more durable, and functional electronic products that meet the demands of modern technology.

What is the Molded Interconnect Substrate Fabrication Process?

The fabrication process of Molded Interconnect Substrates (MIS) involves several steps to create the integrated structural and electrical components. Here’s a general overview of the fabrication process:

  1. Substrate Preparation: The process begins with the preparation of the substrate material, typically a thermoplastic polymer such as polycarbonate or liquid crystal polymer (LCP). The substrate material is typically in the form of sheets or pellets.
  2. Mold Design and Tooling: A mold is designed based on the desired substrate geometry and electrical features. The mold consists of cavities and channels that define the shape of the substrate and accommodate the placement of conductive traces and vias.
  3. Conductive Feature Deposition: Conductive features such as traces, pads, and vias are deposited onto the substrate material using various methods such as laser ablation, printing conductive inks, or metal deposition techniques like sputtering or plating. These features define the electrical interconnections within the substrate.
  4. Molding Process: The substrate material, with the conductive features deposited on it, is placed into the mold cavities. The mold is then closed, and the substrate material is heated to its melting point, allowing it to flow and conform to the shape of the mold. This process encapsulates the conductive features within the substrate material, creating a monolithic structure.
  5. Cooling and Solidification: After molding, the substrate material is cooled and allowed to solidify, maintaining the shape and integrity of the molded part. Cooling may occur gradually to prevent warping or deformation of the substrate.
  6. Post-Processing: Once the substrate has solidified, post-processing steps may be performed, including trimming excess material, surface finishing, and applying coatings or protective layers to enhance electrical performance and durability.
  7. Quality Control and Testing: The fabricated MIS undergoes quality control measures to ensure that it meets the specified electrical and mechanical requirements. This may involve visual inspection, electrical testing, and dimensional verification.
  8. Assembly Integration: Finally, the fabricated MIS may be integrated into larger electronic assemblies or devices through processes such as soldering, adhesive bonding, or mechanical fastening, depending on the application requirements.

Overall, the fabrication process of Molded Interconnect Substrates combines traditional molding techniques with advanced electronics manufacturing methods to create compact, lightweight, and highly integrated electronic components.
