GUTENBACH, GERMANY -- Dyconex is producing 25μm laminates in volume using a Rena cleaning unit, the fabricator said.

Rena developed the unit in response to a Dyconex request for a machine capable of processing foils without assisted transport. The equipment now processes laminates with thicknesses down to 25μm, 2 x 9μm copper layers and applications with lines and spaces as small as 20μm.

The challenge, Rena says, was to develop a solution capable of handling thin foils and simultaneously minimize mechanical damage and surface residues. Furthermore, chemical drag-out between the separated areas had to be significantly improved. Such problems typically appear when processing 25μm laminates with a 50μm equipment, so Rena had to come up with a dedicated thin-laminate solution.

The new machine has now been in use for eight months, Dyconext says. According to Dyconext VP of operations Reinhard Düregger, “We use the equipment for the complete Dyconex product mix, including 25μm laminates with structures down to 20μm lines and spaces.” With this new generation of equipment, we were able to increase product traceability and reduce yield loss due to mechanical damage.”
