As the carrier of electronic components, the number of layers in a multilayer board and the precision of the circuit design determine the size and performance of the circuit board. This industrial-grade robot uses an 8-layer board design with 3 mil / 3 mil line width and spacing, and simultaneously packages 10 sets of ICs and 12 sets of BGAs, making it a high-end product of high-precision printed circuit boards. Main process features: ① Buried and blind via design; ② 3 mil line width and spacing; ③ BGA ball design requires uniform size and consistency; ④ IC green solder mask bridge 4 mil / 4 mil Process characteristics: high-precision interconnection board Technical specifications: 3 mil / 3 mil line width/spacing Finished board thickness: 2.0±0.1mm Outer copper thickness: 35um Surface treatment: immersion nickel gold

The design of high-frequency microwave multilayer boards made by mixing high-frequency substrates with FR-4 has a higher density than low-frequency boards. Generally, high-frequency boards are used in circuits with frequencies above 1G. Its dielectric constant is critical; the DK value is very small and stable, dielectric loss is minimal, and it has excellent properties such as resistance to moisture absorption, heat resistance, and corrosion resistance.
