Mounting components in electronic devices

摘要

An electronic device comprises electronic circuitry and a molded plastic covering (5). In order to prevent ingress of water and dust, a hermetic seal is provided between the covering (5) and components that are accessible through the covering (5), such as a socket (7) or display, or components such as electrical connections (9). The components (7, 9) are at least partially coated in a coating material 15, such as a thermally activated polyurethane adhesive or thin thermoplastic, to provide a strong bond to the covering (5) that does not require the use of solder. The device may be a wearable device in which waterproof sealing is required.
