Our suspension assemblies are manufactured with proprietary technology and processes to uniform and precise specifications. These processes must be tightly controlled and continually improved to meet customers’ specifications.
Suspension assemblies consist of three primary components: loadbeam, flexure and baseplate. We are the only vertically integrated suspension assembly manufacturer. We fabricate all three components from raw materials and then assemble them in our automated focus factories. Vertical integration provides us with advantages in quality, efficiency, cost and speed.
Producing suspension assemblies requires several manufacturing processes, each dependent on different technical disciplines:
Photoetching – We use photoetching technology to produce thin, intricate suspension components with close tolerances that are impossible to duplicate with other production methods, such as stamping or laser cutting. In the photoetching process, optically generated images of our parts are transferred onto thin metal sheets using ultraviolet light. These images define the areas that are to be dissolved (etched) by chemicals and the areas that are to be protected.
Assembly – The components are assembled into a final product by high-speed automated equipment in our focus factories. Process steps include precision forming, laser welding and adjustment of critical product parameters. We use sophisticated measurement systems to acquire and measure geometries, along with automated vision systems to check product quality.
Circuit Manufacturing - In our circuit manufacturing process, we produce intricate electrical conductors, which we call traces, that run lengthwise on the flexure component. We use an additive process to produce these very fine electrical conductors that are thinner than a human hair.
Stamping - High-speed presses utilize progressive dies to form and stamp components to precise geometric dimensions.
