Description

Self-cleaning VCP clamp

Technical Field

The utility model relates to an electroplating device technical field, in particular to automatically cleaning VCP anchor clamps.

Background

In the PCB manufacturing industry today, Vertical Continuous Plating (VCP) is mainly used for electroplating, which has the advantages of large production capacity, stable quality, good uniformity, etc. compared to the conventional gantry-type electroplating line. The general flow of the VCP electroplating process is: loading → microetching → tertiary washing → presoaking → coppering → tertiary washing → antioxidation → secondary washing → drying → unloading → stripping → washing of stripping → clamp drying → loading.

The drying effect of the clamp directly influences the process level of the whole electroplating process, and the existing VCP clamp drying mode mainly adopts an integral drying mode. For example, patent No. 201610675297.0 entitled VCP plating jig drying apparatus adopts a blower pipe connected with a plastic hose to blow air to a moving VCP plating jig through an air outlet, which has a short time for applying air to a single VCP plating jig, and the chuck part is not easily dried.
