Standard Design Description_V0-1_040801(SIDE_KEY) Standard Design Description of Structure Department——(SIDE_KEY)1. OverviewThis document describes the specifications that the employees of the structure department need to follow in design. 2. PurposeTo have a corresponding basis when designing products, to ensure the uniformity, interchangeability and efficiency of data during the project development and design process. To improve work efficiency. 3. Specific content (1). Function description: When the side key is pressed, the side_key_switch (or side_key_metaldome) is pushed to a certain stroke (usually 0.2mm), so as to achieve the purpose of making the side_key_switch (or side_key_metaldome) circuit conductive. (2). Assembly relationship (with peripheral devices): [pic] Figure 1: Schematic diagram of the disassembled state of SIDE_KEY assembly SIDE_KEY and SIDE_KEY_RUBBER are glued together with glue (usually UV glue or instant glue) to form a component, and the thickness of the glue is about 0.5mm. For ease of assembly, the SIDE_KEY component is usually installed on the HSG first, and then the PC board is assembled. Considerations for the design of the assembly dimensions of the SIDE_KEY and peripheral devices: There are two types of side key connectors: SIDE_KEY_SWITCH and SIDE_KEY_FPC I. SIDE_KEY _SWITCH (the commonly used one is CITIZEN\'s LS10N2T, for detailed dimensions and SPEC, please see SIDE_KEY_SWITCH) [pic] Figure 2: SIDE_KEY, SIDE_KEY_SWITCH and HSG assembly dimensions a. The gap size (A) between the SIDE_KEY and the HSG periphery is 0.1mm. If the gap size is too small, it is easy to...
