What is the BT Laminate Substrate Fabrication Process?

The fabrication process for BT laminate substrates involves several steps, including material preparation, layer buildup, etching, drilling, plating, and finishing. Here’s an overview of the typical process:

1. Material Preparation: The fabrication process begins with preparing the BT laminate material. This involves cutting the laminate sheets to the required size based on the design specifications.
2. Layer Stackup: Multiple layers of BT laminate are stacked together according to the desired layer configuration. Each layer may contain copper foil bonded to the laminate substrate.
3. Lamination: The layer stackup undergoes lamination under heat and pressure to bond the layers together into a single composite structure. This process ensures good adhesion between the laminate layers and the copper foils.
4. Circuit Patterning: A layer of photoresist is applied onto the copper foil surfaces. Then, the desired circuit patterns are transferred onto the photoresist using photolithography techniques. This involves exposing the photoresist to UV light through a photomask and developing it to remove the unexposed areas, leaving behind the patterned resist.
5. Etching: The exposed copper areas not protected by the developed photoresist are etched away using chemical etchants. This step removes the unwanted copper, leaving behind the circuit traces according to the patterned resist.
6. Drilling: Holes are drilled into the substrate where vias and component mounting holes are required. High-speed drilling machines are used to accurately drill holes of various sizes through the laminate stack.
7. Desmear and Etchback: After drilling, the drilled holes are cleaned and chemically treated to remove any smear or debris generated during the drilling process. Etchback is performed to remove excess resin from the walls of the drilled holes, exposing the copper for subsequent plating.
8. Plating: Copper plating is applied to the walls of the drilled holes and the exposed copper surfaces to enhance conductivity and provide interconnection between layers. Electroless copper plating followed by electrolytic copper plating is commonly used in this process.
9. Surface Finish: The exposed copper surfaces are coated with a surface finish to protect them from oxidation and facilitate soldering during assembly. Common surface finishes include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservatives).
10. Final Inspection: The fabricated PCB undergoes visual inspection, dimensional measurement, electrical testing, and other quality checks to ensure that it meets the required specifications and standards.
11. Routing and Profiling: The fabricated PCB is routed to separate individual boards from the panel, and the edges are profiled to the final dimensions.
12. Final Testing and Quality Assurance: The finished PCBs undergo final testing to verify functionality and quality before being shipped to the customer.

This fabrication process yields high-quality BT laminate substrates ready for component assembly and integration into electronic devices.
