Historically a rubber seal and gasket company, Modus Advanced, Inc. recently ventured into the machining business due to increased demand for quick turn RF shields. We now produce complete radio frequency (RF) shields from start to finish, beginning with the machining of the aluminum to the dispensing of a form-in-place (FIP) gasket.
Engineers can spend days or even weeks designing the ideal aluminum RF shield for their application. Fastener placement, wall thickness, cavity location, materials and many other factors are engineered to optimize performance. When Modus Advanced, Inc. began milling RF shields, the company was faced with a question; which of the many choices of measuring equipment is best suited to verify our processes are producing shields that meet customer’s specifications?
If you make a mistake during the design phase, you run the risk of going over budget and not receiving your solution in time. Our latest eGuide will help you avoid these common design oversights. Get a free copy by subscribing to our blog.
Silicone form-in-place (FIP) electromagnetic interference (EMI) shielding gaskets have a job to do. The electrically conductive FIP gasket bridges the gap between machined aluminum shields and PC boards create a faraday cage. When designed correctly, machined aluminum shields with conductive FIP gaskets provide effective EMI protection for sensitive electronics. What does “designed correctly” mean? There are obviously many factors that affect shielding performance. They’re all fun and exciting to talk about, but our focus in this blog post is on the use of mechanical compression stops to help avoid gasket related issues.
