The Manufacturing Process of AI Accelerator Module PCBs
The manufacturing process of AI Accelerator Module PCBs involves several precise and controlled steps to ensure high quality and performance. Key steps include:
The design phase involves creating detailed schematics and layouts using computer-aided design (CAD) software. The layout includes the arrangement of conductive traces, vias, thermal management features, and other components necessary for the AI accelerator’s functionality.
High-quality raw materials, including core materials, copper foils, and dielectric materials, are prepared and inspected to ensure they meet the required specifications.
The core material and copper foils are laminated together using heat and pressure to form a unified multilayer structure. This step involves precise alignment and control to ensure the layers are properly bonded.
Vias and microvias are drilled into the PCB to create vertical electrical interconnections. These holes are then plated with copper to establish conductive pathways.
The circuit patterns are created using photolithographic processes. This involves applying a photosensitive film (photoresist) to the copper surface, exposing it to ultraviolet (UV) light through a mask, and developing the exposed areas to reveal the desired circuit patterns. The PCB is then etched to remove the unwanted copper, leaving behind the circuit traces.
Dielectric layers are applied to insulate the conductive layers. This step involves coating the PCB with a dielectric material and curing it to form a solid layer.
Heat sinks, thermal vias, and copper planes are integrated into the PCB to manage heat dissipation. This step is crucial for ensuring the reliable operation of high-power AI accelerators.
Surface finishes such as ENIG, OSP, or immersion tin are applied to the contact pads to improve solderability and protect against oxidation. These finishes are applied using plating or immersion techniques.
A protective layer of solder mask is applied to the PCB to prevent solder bridges and protect the circuitry from environmental damage. The solder mask is typically applied using screen printing or photolithographic techniques.
The final PCBs undergo rigorous inspection and testing to ensure they meet all performance and reliability standards. Electrical testing, visual inspection, and automated optical inspection (AOI) are used to identify any defects or irregularities.
