Die Cutting of a Copper Foil Bottom Shield for the Motion Control Industry

Based on our experience, award-winning staff, and ability to provide a wide array of solutions for our customers, Specialty Printing & Processing’s was recently commissioned by a customer in the motion control industry to develop a copper foil bottom shield for use within a magnetic/electronic monitoring application providing electronic shielding for the component.

Engineering of this project is a testament to our solution-based thinking and diverse capabilities. For this project we developed an innovative solution in which special inks were used to create selectively conductive images. This eliminated an entire component from the assembly, driving cost out of the product. Using AR Clad S-6738 1oz. rolled copper foil with pressure sensitive heat resistant acrylic adhesive and a 60 lb. release liner, the shield offered many tailored benefits that suited the customer’s specific requirements. We integrated polyester as an insulator from the copper shielding from the circuit board. Additional zone printed insulation protects the face of the shield from top surface components, while allowing selective bonding point to ground the shield. The pressure sensitive adhesive backing allows for accurate positioning during the assembly process prior to the assembly being completed. The completed copper foil bottom shields measured 4.435” long, .964” wide, and were within tight tolerances of ±0.005”. The 3575 piece product run was completed within a 7 day production cycle. Quality control was maintained through visual inspection and dimension measurement to ensure accuracy and functionality of the completed project.
