Secondly, heat dissipation design is an important aspect that cannot be ignored in the design of ultra-thin CPU BGA substrate. Due to the size limitations of ultra-thin substrates, the heat dissipation effect may be affected. Therefore, designers need to adopt effective cooling solutions, such as strengthening the heat sink design, optimizing the heat dissipation channel layout, etc., to ensure that the CPU and other chips can maintain appropriate temperatures when working under high loads and prevent overheating from causing system performance degradation or even failure.

In addition, signal integrity is also an aspect that needs to be paid attention to in the design of ultra-thin CPU BGA substrate. Designers need to properly plan signal lines to avoid signal interference and loss and ensure stable signal transmission. This involves precise control of the length, width, layer spacing, impedance matching and other parameters of the signal line, as well as the reasonable layout of the signal layer and power layer.

During the design process, designers need to balance size and performance while maintaining substrate stability and reliability. This means optimal layout and design in the smallest possible space, ensuring that substrate thickness and weight are minimized without compromising system performance and stability.

This is usually achieved through photolithography techniques, which use photoresist and masks to transfer patterns to the substrate surface. This step determines the accuracy and precision of the circuit layout.

Next comes the plating process. The copper foil on the surface of the substrate needs to be thickened to provide sufficient conductivity. The electroplating process involves coating a thin layer of copper on the surface of a substrate and then immersing it in an electrolyte containing copper ions. Electric current is used to deposit copper ions onto the surface of the substrate, ultimately forming a uniform layer of copper foil.

Etching is one of the key steps in the manufacturing process. In this step, unnecessary copper foil is removed through chemical etching, so that only the remaining copper foil on the designed circuit pattern remains. This step requires a high degree of precision and accuracy to ensure circuit connectivity and stability.

Finally comes the assembly stage. At this stage, the ultra-thin CPU BGA substrate that has been manufactured will be installed with various chips, components, etc. This process includes steps such as soldering, packaging, and testing to ensure that each component is connected correctly and that the entire board is functioning properly.
