The manufacturing process of ultra-thin BT PCB is a complex and precise process involving multiple key steps, each of which requires a high degree of technology and process control. The following is a detailed introduction to the manufacturing process:

The first step in manufacturing ultra-thin BT PCB is to prepare the substrate. The substrate is usually composed of fiberglass and epoxy resin and is treated with a special process to ensure surface smoothness and material strength.

On the surface of the substrate, photolithography technology is used to print circuit patterns onto a photosensitive film covering the substrate. The circuit pattern is transferred to the substrate surface through steps such as photolithographic exposure, development and etching.

After the circuit pattern is printed, chemical etching is performed to remove the metal that is not protected by the photolithographic layer, thereby forming the desired circuit path. Chemical corrosion is a precise process that requires strict control of corrosion time and solution concentration.

After the circuit path is completed, a high-precision drilling machine is used to drill holes into the PCB to install electronic components and achieve circuit connections. For ultra-thin BT PCB, the precision of drilling and surface quality are crucial to ensure component robustness and connection reliability.

The final step is to metallize the PCB, which is to apply a metal layer, usually copper, to the surface of the circuit paths and holes. Metallization enhances the electrical conductivity of a circuit and protects it from the effects of oxidation and corrosion.

In the manufacturing process of ultra-thin BT PCB, special attention needs to be paid to the handling and process control of the substrate. Due to the particularity of ultra-thin PCB, special processes are required to ensure its flatness and stability. For example, during chemical etching and metallization processes, temperature, pressure, and the ratio of chemical solutions need to be strictly controlled to prevent substrate deformation or defects. In addition, sophisticated equipment and highly trained operators are also key factors in the success of manufacturing ultra-thin BT PCBs.

To sum up, the manufacturing process of ultra-thin BT PCB requires precise technology and strict process control to ensure the quality and performance of the final product.
