What is the Megtron 7N Substrate Fabrication Process?

The fabrication process of Megtron 7N substrate generally involves several key steps, similar to standard PCB manufacturing but tailored for its specific material properties. Here’s an overview:

Material Preparation: Megtron 7N sheets are cut to the desired size and prepared for lamination. The substrate is typically made of a glass-reinforced epoxy material designed for high-frequency applications.
Layering: If the design includes multiple layers, the layers are stacked according to the required stackup configuration. This may involve adding prepreg layers between core layers.
Lamination: The stacked layers are subjected to heat and pressure in a lamination process, which cures the resin and bonds the layers together. This step is critical for ensuring mechanical stability and electrical performance.
Drilling: After lamination, holes are drilled for vias and mounting holes. The drilling process needs to be precise to avoid damaging the substrate and to maintain the integrity of high-frequency signals.
Copper Plating: The drilled holes are plated with copper to create conductive pathways. This can involve electroless copper plating followed by electrolytic plating to achieve the desired thickness.
Etching: The copper layers are etched to create the desired circuit patterns. This involves applying a photoresist layer, exposing it to UV light, and then etching away unprotected copper.
Surface Finish: A surface finish is applied to protect the copper and improve solderability. Common finishes include immersion gold, HASL, or ENEPIG, depending on the application requirements.
Testing and Inspection: The fabricated substrates undergo electrical testing, visual inspection, and other quality control measures to ensure they meet specified performance standards.
Final Cutting and Packaging: Once testing is complete, the substrates are cut to the final dimensions and packaged for shipment.

These steps are designed to optimize the unique properties of Megtron 7N, ensuring high performance in applications that demand reliability and speed.
