Metal pick-and-place caps for SMD bobbins, for example, combine both the fixing and pick-and-place functions in a single clamp. This reduces the total number of parts from three to one. The C-shaped pin construction has mechanical advantages too, as it separates the wire termination function from electrical connection, and so ensuring excellent coplanarity.
Our choice of materials…
...your assurance of conformity
When selecting materials for our products, the design, production process, electrical- and mechanical requirements are important factors. But above all, we aim for optimum performance at an acceptable price. Many materials are used, ranging from industry-standard polyamide (PA) to the more exotic liquid crystal polymers (LCP) and thermosetting phenolic materials (PF).
Meeting today’s standards
> Underwriter Laboratories (UL) compliance – all polymeric
materials used in our bobbins and accessories are tested and in full compliance with UL;
> Environmental acceptance – as part of our ISO 14001 certification, all materials are screened and shown to be free from banned substances according to agreed Ferroxcube standards.
Matching materials to special requirements
> Smaller surface-mount bobbins – are made from high-performance thermoplastic LCP;
> Larger bobbins – are made from thermosetting materials because thick winding wires require extra mechanical stability at high soldering temperatures;
> Square section pins – help reduce the number of wrappings needed to secure copper wires to the pins.
