PLATE TECHNOLOGY

The right tool matters

The precision and quality of a multi-layer circuit is, among other things, largely determined by the press tool. Therefore, selection and design of the tool is of utmost importance. It must meet the highest requirements in regards to precision of the hole distances, hole dimensions (for PinLam), parallelism, and flatness.
