Leadframe molding re-invented

Besi has reinvented leadframe molding with the AMS-X. The increased market demand for power products and higher densities on larger leadframes asked for a new solution. With the AMS-X Besi has set a new benchmark in leadframe molding.

The AMS-X has newly developed plate presses. An extremely compact and rigid construction. To obtain a bleed free end product, each press has 4 clamp modules that ensure a high and even clamp force all around the product.
And with its new UX-design, the AMS-X is the most user friendly Besi molding system ever.
