The shielding case is connected to GND in the module. For mounting the module, when pattern wiring that touches the shielding case is carried out on the product board, do not cause a short-circuit between the shielding case and the pattern. For example, apply resist on the entire surface that touches the shielding case. 2. The effects of noise on a product board depend on the connection of GND/NC to the fixation pads. Select the connection with better electrical characteristics in the module mounted state. CAUTIONS IN USE This module consists of precision electronic components. Therefore, note the following when handling the module: 1. In a case of decomposition or recomposition of this module, the operations in these specifications are not assured. 2. This module is not waterproof or drip-proof. Do not use the module in wet locations. 3. Do not use this module under high temperature or high humidity conditions, in direct sunlight, or in dusty places. 11/14 PEDL70215-01 OKI Semiconductor MK70215 MODULE OUTLINE Outline of MK70215 OKI MK70215 1 6 .7 0 .1 m m 1 7 .5 0 .1 2 7 m m Lot.
