Abstract

Plating selected surfaces of devices such as magnetic heads requires careful masking. Such is to insure that only the surface to be plated is exposed to the plating bath and any related cleaning or etching solutions. This is usually accomplished by mounting the device in a box-like framework and covering all surfaces which are not to be plated with a protective material such as RTV rubber. The method shown holds and protects magnetic heads of different dimensions without requiring any coating or potting. Two metallic brackets 10 and 11 form an adjustable clamping collar within which transducer 12 is received. Clamping bolts 13 thread into ears 14 at the opposite ends of the brackets to tighten them around the transducer 12.

Plating Fixture

Plating selected surfaces of devices such as magnetic heads requires careful masking. Such is to insure that only the surface to be plated is exposed to the plating bath and any related cleaning or etching solutions. This is usually accomplished by mounting the device in a box-like framework and covering all surfaces which are not to be plated with a protective material such as RTV rubber. The method shown holds and protects magnetic heads of different dimensions without requiring any coating or potting. Two metallic brackets 10 and 11 form an adjustable clamping collar within which transducer 12 is received. Clamping bolts 13 thread into ears 14 at the opposite ends of the brackets to tighten them around the transducer 12. Flexible coating 15 of vinyl-chloride plastic, such as KOROSEAL*, is formed around the collar to provide a good seal against transducer 12. This coating is shaped to form a loose receptacle or bag 15a, depending from the collar to cover the body of transducer 12, leaving only the to-be-plated surface exposed. Contact screws 16, threaded through brackets 10 and 11, are tightened against transducer 12 and are connected to the electroplating apparatus to provide anodic contact. These screws also serve to support a conventional robber or thief 17, shown in phantom, above the surface to be plated. *Trademark of B. F. Goodrich Chemical Co.
