Compared with double-sided circuit boards and 4-layer circuit boards, 6-layer circuit boards have more layers and are therefore more conducive to routing. However, at the same time, the fabrication cost and production difficulty of 6-layer circuit boards are also Will increase.
With the continuous development of SMT (Surface Mount Technology) and the continuous introduction of a new generation of SMD (Surface Mount Devices), such as QFP, QFN, CSP, BGA (especially MBGA), electronic products are more intelligent and miniaturized, so Promoted major reforms and advances in PCB industrial technology.
Therefore, the advancement of PCB manufacturing technology has also made the manufacturing of 6-layer PCBs easier.
