Ceramic Substrates manufactured for large scale electronic applications such as IC packages are being routinely improved by utilizing the HED International Lab-Cast Model TC-71LC Tape Casting machine designed specifically for bench scale projects. The results on Lab-Cast are scalable to larger production machines such as Pro-Cast Model machines up to 2 m wide and 50 m long. Dried cast tape of typical ceramic substrates is about 0.75 mm (0.03 inch) thick, optimum drying time or when the highest quality tape is ready to be harvested from the tape caster can be determined on the Lab-Cast. Product quality improvements such as this are achievable with the Lab-Cast on non-aqueous solvent based tapes, typically used to produce substrates and water based products as well.
