摘要: An electrical contact area on a printed circuit board (“PCB”), that would otherwise be subject to abrasion and possibly also corrosion, can be protected by covering it with another, more durable contact structure that is bonded to the first-mentioned contact area using an anistropic conductive adhesive (“ACA”). The more durable contact structure may include a member of PCB material or the like with electrically connected electrical contacts on its upper and lower surfaces. At least the upper one of these contacts (which is exposed for the service that involves possible abrasion and/or corrosion) may be given high durability by plating it with hard gold. The lower of these contacts is adhered to the main PCB via the above-mentioned ACA.

摘要: An improved handheld electronic device and keypad include tactile features that help a user to identify certain keys of the keypad. In the present exemplary embodiment, the keypad includes keys in a predetermined region that can be employed during a telephone operation. The keypad additionally includes other keys outside the predetermined region. The keys in the predetermined region include tactile features that enable the user to identify and actuate the keys in the predetermined region during a telephone operation with the user directing minimal visual attention to the handheld electronic device.
