Multiple layers of boards are required. Although the manufacturing of multi-layer printed circuit boards uses the same process as single-layer boards, obtaining more accurate Electronic Manufacturing Services user data! However, each company's demand for PCB boards is opposite. For example, if only a simple "two layer" design is required, it would involve using a single layer of conductive graphics, but not the use of conductive graphics. The more layers a multi-layer board has, the more complex the manufacturing process involves, which requires a more complex number of layers. In other words, the more layers there are, the more complex the choices the manufacturer needs.
There are many ideas for complex boards, but they can be designed as circuit boards with multiple functions, which means it is a good hardware layer that is not limited by materials, does not affect the number of holes drilled, and does not have a significant impact on components.
Small through-holes and accurately narrow apertures. The more the number and model of through-holes, the higher their cost. At the same time, it is best to have clear markings when disassembling these small apertures.
Due to its electronic nature, there is no feeding contact on the plane corresponding to a point, resulting in a large contact area. The common mode current introduced by the voltage from the power supply contact to the power supply terminal flows through it.

Due to the presence of copper wire on the plane corresponding to a point, contact with the copper wire can also generate high-frequency oscillations, affecting the surrounding inductance and emitting AC noise to the surrounding area.

Only batteries can have good charging and discharging performance, which puts forward new requirements for designers' design to meet people's daily safety requirements.
