Abstract: A shielded low-profile electronic component assembly 100 providing shielding for electronic components is disclosed which includes a substrate 124, and shield 102. In a first embodiment the shield 102 is chamfered at each shield corner 110 and is attached to the substrate 124 at ground pad patterns 114, which are found at each corner of the substrate 124 on surface 128. A ground paddle 120 is also located in substrate 124 which lies substantially underneath the electronic component 112, and is utilized in maximizing shielding. In an alternate embodiment a substrate 124 is overmolded with encapsulation material 302 after the electronic component 112 is affixed to the substrate 124, with each of the encapsulation material corners 306 being chamfered exposing ground pads 114. The metallized shield 310 is then placed over the overmolded encapsulant and attached to the substrate 124 at ground pad patterns 114. The overmolded encapsulant 302 adding protection to the electronic component 112.

Abstract: A knob (100) comprises an inner portion (105) made of a nonmetallic material and an outer portion (102) molded over the inner portion (105). The outer portion (102) comprises a material having a reduced hardness factor with respect to the inner portion (105).

Abstract: The programmable electronic device, such as a radio, includes a memory for storing program information. A controller, such as a microprocessor, is connected to the memory for programming and reading the memory. A keypad is provided for data entry and is connected to the microprocessor. A magnetic switch, such as a Hall effect switch, is located within the radio and controls the program enable line of the microprocessor. The Hall effect switch is actuated by an externally supplied magnetic field for enabling programming of the memory of the radio.
