To ensure reliability, please verify quality under conditions of actual use. 2. Mounting Use lands on the PC boards to which the sensor can be securely fixed. • Malfunctioning may occur if much noise is present in the power supply used for this product. In order to prevent, in particular, superimposed noise, please install the recommended capacitor between the sensor input terminals (between VDD and GND) closest to the sensor (a position within 20 mm of the pattern circuit length). However, please reselect an ideal capacitor after performing tests on the actual equipment. • Since the top surface (where the part number is visible) of the sensor is GND, please make sure that the metallic parts of other components do not come into contact. 3. Soldering • Take steps to minimize the effects of external heat. Damage and changes to characteristics may occur due to heat deformation. • Use a non-corrosive resin type of flux. 1) Manual soldering • Set the soldering tip from 350 to 400°C 662 to 752°F (30 to 60W), and solder for no more than 3 seconds. • Please note that output may change if the pressure is applied on the terminals when the soldering. • Thoroughly clean the soldering iron. 2) Reflow soldering • The recommended reflow temperature profile conditions are given below. • We recommend the screen solder printing method as the method for cream solder printing. • Please refer to the recommended PC board pad for the PC board foot pattern. • Self alignment may not always work as expected; therefore, please carefully adjust the position of the terminals and pattern. • The profile temperature is the value measured on the PC board near the terminals. • When doing reflow soldering on the back of the PC board after performing sensor reflow, please fix the sensor with adhesive and so on. 3) Solder reworking • Finish reworking in one operation. • For reworking of the solder bridge, use a soldering iron with a flat tip. Please do not add more flux when reworking. • Please use a soldering iron that is below the temperature given in the specifications in order to maintain the correct temperature at the tip of the soldering iron. 4) Too much temperature on the terminals will cause deformation and loss in effectiveness of the solder. Therefore, please avoid dropping and careless handling of the product. 5) When cut folding the PC board after mounting the sensor, take measures to prevent stress to the soldered parts. 6) The sensor terminals are designed to be exposed, so contact of the terminals with metal shards and the like will cause output errors. Therefore, please be careful and prevent things such as metal shards and hands from contacting the terminals. 7) To prevent degradation of the PC board insulation after soldering, please be careful not to get chemicals on the sensor when coating. T3 T2 T1 t1 t2 T1 = 150 to 180°C 302 to 356°F T2 = 230°C 446°F T3 = Max. 250°C 482°F t1 = 60 to 120 sec. t2 = With in 30 sec. 4. Connections • Please perform connections correctly in accordance with the terminal connection diagram. In particular, be careful not to reverse wire the power supply as this will cause damage or degrade to the product. • Do not connect “NC” terminals that are not used. This can cause malfunction of the sensor. 5. Cleaning • Avoid ultrasonic cleaning since this may cause breaks or disconnections in the wiring. 6. Environment • Please avoid using or storing the sensor in a place exposed to corrosive gases (such as the gases given off by organic solvents, sulfurous acid gas, hydrogen sulfides, etc.) which will adversely affect the performance of the sensor. • When installing the sensor, you must provide a capacitor as shown in the recommended circuit diagram. • Since the internal circuitry may be destroyed if an external surge voltage is supplied, provide an element which will absorb the surges. • Malfunctioning may occur if the product is in the vicinity of electrical noise such as that from static electricity, lightning, a broadcasting station, an amateur radio, or a mobile phone. • Please do not use the sensor in a location where it may be sprayed with water, etc. • Avoid using the sensor in an environment where condensation may form. Furthermore, its output may fluctuate if any moisture adhering to it freezes. • Avoid using the sensor where it will be susceptible to ultrasonic or other highfrequency vibration. 7. Other handling precautions To assure reliability, check the sensor under actual loading conditions. Avoid any situation that may adversely affect its performance. • This product may malfunction if dropped on its own before it is installed. Do not use if this happens. • Caution is required because differences in the acceleration detection range and the method of connection can lead to accidents. • The actual acceleration should be within the rated acceleration range. Damage may occur if it is outside of this range. • This product may become damaged if exposed to static electricity. Therefore, please be careful, as follows, when handling. (1) Since plastic containers easily hold a charge, please do not use them for storage or transport. (2) Please store or transport the product in an environment that hinders the occurrence of static electricity (for example, places with 45% to 60% humidity) and protect the product using electrically conductive packaging. (3) Implement static electricity prevention measures once the product packaging has been opened. • Any personnel handling the sensor should wear electrostatic clothing and be body grounded. • Place an electrically conducting board on the work surface and ground any devices used such as measuring instruments and jigs. • Use a soldering iron with a low leak current or else ground the tip. • Make sure that customer equipment used for device assembly is grounded. (4) Since the internal circuitry may be destroyed if an external surge voltage is supplied, provide an element which will absorb the surges.
