What is the Advanced BT BGA Substrate Fabrication Process?

The fabrication process for Advanced BT (Bismaleimide Triazine) BGA (Ball Grid Array) substrates involves several steps to create the intricate layers and patterns required for high-performance semiconductor packaging. Here’s an overview of the typical fabrication process:

1. Substrate Preparation:The process begins with the preparation of the base substrate material, which is usually a composite laminate consisting of layers of BT resin and reinforcing materials such as fiberglass or polyimide. The substrate material is typically supplied in large sheets or panels.
2. Layer Stacking: Multiple layers of substrate material are stacked together to form a multi-layered structure. Each layer may have different properties, such as signal routing, power distribution, or ground planes. Alignment is critical during this step to ensure precise registration of features across the layers.
3. Drilling: Small holes, or vias, are drilled through the stacked substrate layers at specific locations where electrical connections are needed between different layers. These vias will later be filled with conductive material to create inter-layer connections.
4. Electroplating: After drilling, the vias are plated with a conductive material, typically copper, to establish electrical continuity between the layers. Electroplating ensures that the vias have a uniform and reliable conductive coating.
5. Lamination:The stacked and plated substrate layers undergo lamination under heat and pressure. This process bonds the layers together permanently, forming a solid composite structure. The lamination process also helps to remove any air voids and ensure good adhesion between the layers.
6. Circuit Patterning: Photolithography and etching processes are used to define the circuit patterns on the substrate layers. A photoresist material is applied to the substrate surface, exposed to UV light through a photomask containing the desired circuit pattern, and then developed to remove the unexposed areas. The exposed substrate is then etched to remove the underlying material, leaving behind the circuit traces and features.
7. Surface Finishing: The substrate surface is finished to prepare it for component attachment. This may involve applying solder mask and surface finish materials such as solder or gold to provide protection, facilitate soldering, and ensure good electrical contact.
8. Testing and Inspection: The fabricated substrate undergoes rigorous testing and inspection to verify dimensional accuracy, electrical continuity, and reliability. Various testing methods, such as electrical testing, X-ray inspection, and automated optical inspection (AOI), are used to ensure that the substrate meets quality standards.
9. Final Processing: After testing and inspection, the fabricated substrate may undergo additional processing steps, such as laser marking, panelization, or packaging, depending on the specific application requirements.

By following these fabrication steps with precision and attention to detail, manufacturers can produce Advanced BT BGA substrates with the high performance and reliability needed for demanding semiconductor packaging applications.

How do you Manufacture an Advanced BT BGA Substrate?

Manufacturing an advanced BT (bismaleimide triazine) BGA (ball grid array) substrate involves several steps and specialized processes. Here’s a general overview of the manufacturing process:

1. Material Selection: Choose high-quality BT resin and reinforce it with glass or other suitable fibers to enhance its mechanical and thermal properties.
2. Prepreg Production: Prepare prepreg sheets by impregnating the reinforcement material with the BT resin. This can be done using methods like hot pressing or resin infusion.
3. Circuit Formation:Print or etch the desired circuit pattern onto the prepreg sheets using methods like screen printing, photolithography, or laser ablation. This creates the conductive traces on the substrate.
4. Layer Stacking: Stack multiple prepreg layers together, interleaving them with conductive foil layers as necessary. This forms a multilayer substrate with alternating layers of prepreg and conductive material.
5. Lamination: Apply heat and pressure to the stack of prepreg layers to laminate them together. This process melts the resin and bonds the layers into a single solid substrate.
6. Drilling and Plating: Drill holes (vias) through the substrate where connections between layers are needed. Plate these vias with conductive material (such as copper) to create electrical connections between layers.
7. Surface Finishing: Apply surface finishes to the substrate to protect it from oxidation and improve solderability. Common surface finishes include immersion tin, immersion silver, electroless nickel immersion gold (ENIG), and organic solderability preservatives (OSP).
8. Solder Mask Application: Apply a solder mask over the substrate, leaving openings for the solder balls or bumps in the BGA array. The solder mask protects the substrate and defines the soldering areas.
9. Solder Ball/Bump Attachment: Attach solder balls or bumps to the substrate using methods like solder ball placement machines or solder paste stenciling followed by reflow soldering.
10. Testing and Inspection:Perform electrical testing and visual inspection to ensure the substrate meets quality standards and specifications.
11. Packaging and Shipping: Package the substrates securely for transport to customers or assembly facilities.

Throughout the manufacturing process, stringent quality control measures should be implemented to ensure the final product meets the required performance and reliability standards. Advanced manufacturing techniques, such as laser drilling and automated assembly, may also be employed to improve efficiency and precision. Additionally, compliance with relevant industry standards and regulations, such as IPC standards for PCB (printed circuit board) manufacturing, is essential.
