Main Factors Affecting The Complexity of PCB Urgent Prototyping

The complexity of PCB uggent prototyping depends on the number of layers and the number of vias on each layer, because this defines the changes in the layers where vias start and stop, and more lamination and drilling steps are required in the PCB manufacturing process. The manufacturer defines the lamination process as using heat and pressure to press two copper layers and a dielectric between adjacent copper layers to form a multilayer PCB laminate.

Since the through-hole structure mainly affects the manufacturing process, manufacturers such as PCB urgent prototyping are optimized by using micro-via and high-density integration (HDI) technology. HDI technology not only reduces the overall cost by reducing the number of layers, but also makes the PCB smaller, lighter, and thinner, while providing better electrical performance.

The selection criteria for the materials used to manufacture PCB expedited proofing depends on several application-based factors, which mainly depend on the frequency and operating speed as well as the maximum operating temperature.

These factors include thermal stability, temperature-related reliability, temperature cycle reliability, heat transfer rate, delamination time, and so on. In fact, the higher the operating frequency or speed of the signal, the more important is the choice of materials used to manufacture PCB urgent prototyping. For example, compared with conventional phenolic FR-4 materials, the use of polyimide will increase the cost by about 3-5 times, but the use of PTFE-based microwave materials may increase the cost by nearly 10-50 times.
