Chomerics Europe has introduced a FIP (form-in-place) EMI gasketing material that is designed for use in portable equipment, telecomms, and military and marine products. With a hardness of 48 (±5) shore A, the CHO-FORM 5547 gasketing material is useful in applications where assembly closure forces are low and can eliminate the need for fasteners or rigid housings. The gasketing material utilises nickel-plated silver particles dispersed in a silicone binder to deliver a shielding performance of over 70dB. It can be placed on narrow housing flanges using the FIP dispensing technology. This reduces assembly labour and total cost of ownership and also allows the use of small package sizes for PCBs. The gasketing material is supplied in 30 or 55cc syringes that support rapid prototyping or a 300cc cartridge. It is suitable for use in applications with operating temperature ranges from -50 to +130°C.
