The thickness and uniformity of the copper layer are critical to the performance of the final circuit and therefore require precise control and monitoring.
This is followed by the photoresist coating and exposure steps. Photoresist is coated on the surface of the copper layer and exposed through a photolithography machine, using an optical mask to form a circuit pattern. After exposure, portions of the photoresist are cured or removed, exposing areas that need to be etched.
Etching is the next critical step. Through chemical etching or electrochemical etching, the portion of the copper layer that is not protected by the photoresist is removed to form conductive paths and pads. The accuracy of this step determines the accuracy and reliability of the circuit.
This is followed by the drilling process, which drills holes in predetermined locations for mounting the devices and making interconnections. These holes are located at the pad positions and connection points reserved in the design, ensuring the correct positioning of the components and the reliability of the interconnection through drilling.
Component installation is an important part of the manufacturing process, covering two main technologies: patch technology (SMT) and through-hole mounting. SMT is suitable for the mounting of small components and high-density integrated circuits, while through-hole mounting is suitable for applications requiring greater force and high current.
Finally comes the welding and testing phase. Soldering secures components to pads with molten solder and ensures electrical connections. The testing phase includes electrical testing, functional testing and reliability testing to verify that the manufactured chip packaging substrate meets the design specifications and performance requirements.
