Mounting Do not operate the DIP Switch while mounting, soldering, or washing the DIP Switch, otherwise the DIP Switch may deform due the heat of the solder, the DIP Switch may malfunction due to the penetration of the washing agent, or the machine incorporating the DIP Switch may operate or be set incorrectly. An automatic insertion machine incorporating a body stopper is available for mounting the DIP Switch. When using an automatic insertion machine incorporating a half-lead stopper to mount the DIP Switch, make sure that the automatic insertion machine will not deform the terminals of the DIP Switch, otherwise the improper insertion of the DIP Switch may result. 3 A6T/A6S A6T/A6S Soldering Washing Observe the following conditions when soldering the DIP Switch. Washable Automatic Soldering Bath Soldering temperature: 260°C max. Soldering time: 5 s max. for a 1.6-mm thick, single-side PCB A6T (with seal tape), A6S (with seal tape) Not washable A6T (standard/raised actuator), A6S (standard/raised actuator) Reflow Soldering Soldering temperature (°C) Soldering time 2 minutes max. 20 seconds max. Manual Soldering Soldering temperature: 350°C at the tip of the soldering iron. Soldering time: 3 s max. for a 1.6-mm thick, single-side PCB Set the pins of the DIP Switch to OFF before soldering the DIP Switch. Before soldering the DIP Switch on a PCB, make sure that there is no unnecessary space between the DIP Switch and PCB. Before soldering the DIP Switch on a multilayer PCB, make sure that the DIP Switch will not be deformed by the soldering heat on the pattern or land of the multilayer PCB. Do not solder the DIP Switch more than twice including rectification soldering. An interval of five minutes is required between the first and second solderings. Make sure that there is no flux rise on the surface of the PCB. PCB surface Flux 4 Ultrasonic cleaning is unavailable to any A6T or A6S-series DIP Switch with a seal tape. It is possible to wipe or dip these models into washing agents for one minute maximum. Apply fluorocarbon or alcoholic solvents to clean washable models. Do not apply any other solvents or water to clean any washable model because they may deteriorate the materials or performance of the model. Washing equipment incorporating more than one washing bath can be used to clean washable models provided that the washable models are cleaned for one minute maximum per bath and the total cleaning time does not exceed three minutes. Do not impose any external force on washable models while washing. Do not clean washable models immediately after soldering. Wait for at least three minutes to clean washable models after soldering. The A6T or A6S-series DIP Switch with a seal tape can be washed provided that the seal tape is not removed or pasted before washing the DIP Switch. A6T/A6S A6T/A6S Handling Do not apply excessive operating force to the DIP Switch, otherwise the DIP Switch may be damaged or deformed, thus causing the switch mechanism to malfunction as a result. Apply an operating force not exceeding 200% of the maximum rated operating force to the DIP Switch. Set the DIP Switch incorporating slide pins with a tiny, rounded object, such as the tip of a ball-point pen or small screwdriver. Do not set the DIP Switch using tweezers or any other sharp object, which may damage the DIP Switch. Do not set the DIP Switch using the point of a mechanical pencil, otherwise lead powder or fragments may fall into the DIP Switch and internal circuit board, causing the DIP Switch to malfunction and reducing the dielectric strength of the circuit board.
