A-TECH has built a reputation in the manufacture of blind vias pcb. Our extensive manufacturing experience has been built over the last years. A-TECH's single-sided PCB series contains multiple sub-products. The design of impedance calculator pcb is much bolder than usual blind vias pcb. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo. osp pcb offers several advantages in terms of enig pcb finish. A smooth part is added on its PTH line to reduce the roughness of through hole.
We adhere to the principle of 'build a reputation via innovation'. We will continue to invest in talents development and R&D. Get info!
