AI Technical Summary
In the existing circuit board manufacturing process, impedance consistency is poor, and frequent first-piece testing is required, which necessitates equipment downtime, consumes a lot of time and resources, and affects production capacity and product quality.
By setting parameters such as dielectric constant Er of the dielectric layer, impedance linewidth W, line spacing S, distance from line to copper D, and ink thickness, the Si9000 software is used to calculate the simulated impedance value. By adjusting the impedance linewidth and line spacing parameters, the simulated impedance value is made to meet the design requirements of the actual finished product impedance value, thus reducing the gap.
It improves the consistency of circuit board impedance, reduces the frequency of first-piece testing during production, reduces equipment downtime, saves energy, and improves product quality.
