What is the Fabrication Process for a 20 Layer BGA/IC Substrate?

Select and prepare the substrate material according to design specifications. This may involve laminating multiple layers for organic substrates or preparing ceramic or metal core materials.

Layers are laminated together under high pressure and temperature, ensuring proper alignment and bonding.

Drill holes for vias and component leads with precision to maintain the integrity of the thin PCB.

Plate the drilled holes and vias with copper to create electrical connections between the layers, ensuring reliable signal transmission and mechanical stability.

Use photolithography to transfer the circuit pattern onto the laminate material by coating it with a photosensitive film, exposing it to UV light through a mask, and developing the pattern.

Etch away the unwanted copper to reveal the desired circuit pattern, requiring precise control to ensure accurate and clean traces.

Fill vias with conductive or non-conductive material and planarize the surface to ensure a smooth and level substrate.

Apply a surface finish, such as ENIG (Electroless Nickel Immersion Gold) or HASL (Hot Air Solder Leveling), to protect the copper traces and ensure good solderability.

Perform assembly, including component placement and soldering, followed by rigorous testing to verify the PCB’s performance and quality, including electrical, thermal, and mechanical tests.
