Design engineers use CAD software to create circuit layouts and connection diagrams, ensuring that the location and size of each pad meets specification requirements.

Substrate preparation

During the manufacturing process, the substrate material first needs to be prepared. Typically, a high-quality insulating material such as FR4 (fiberglass reinforced epoxy) or polyimide (PI) is used as the substrate. The surface of the substrate is then coated with a thin conductive layer, usually using copper foil.

Image transfer

Next comes the image transfer step. This step uses photolithography technology to transfer the designed circuit pattern to the copper foil layer. First, a layer of photosensitive adhesive is coated on the surface of the copper foil, and then the negative of the circuit pattern is placed on the photosensitive adhesive and exposed to ultraviolet light. Subsequently, development and etching are performed to remove the unexposed photosensitive adhesive and copper foil, leaving the required circuit pattern.

Drilling and plating

After completing the circuit pattern, drilling and plating processes are required. This step involves using a drill to drill holes in the substrate for connecting wires between different layers. The drilled surface is then chemically treated to increase conductivity and a layer of metal, usually copper or nickel, is plated inside the hole and over the circuit pattern.

Solder Mask and Silk Screen

After drilling and plating are completed, a layer of solder mask needs to be applied to the surface of the substrate to protect the copper foil and circuit patterns. Solder mask is usually a green or other colored epoxy resin that can effectively prevent oxidation and short circuits. In addition, silk screen printing can also be performed on the surface of the substrate to print component identification and other necessary information.

Testing and inspection

The final step is to test and inspect the manufactured ultra-thin FC-LGA substrate. By using professional testing equipment, the electrical performance of the substrate is comprehensively tested to ensure the connectivity and stability between each pad. At the same time, optical inspection and visual inspection are performed to ensure that there are no defects and blemishes on the surface of the substrate.
