The carrier tray is a high-temperature, high-pressure, and high-precision metal tray used in printed circuit board/copper clad laminate production equipment.
High temperature resistance without deformation, wear-resistant and scratch-resistant, stable and uniform thermal conductivity, long life and low maintenance.
The key carrier for achieving high-quality lamination of printed circuit boards and copper-clad laminates directly determines the lamination yield and board quality.
