PCB Mounting (Top View) Terminal Arrangement /Internal Connections (Top View) Precautions Reflow Soldering Attach a thermocouple to one side of the terminal with high-temperature solder and use the thermocouple to set the reflow oven to a peak terminal temperature of 230°±5°C. The optimum heating curve is shown below. 10 s max. 1 to 4°C/s 1 to 5°C/s Do not apply additional force to the plunger once it has stopped moving. Do not repeatedly press the plunger off-center or from an acute angle. B3S Switches are designed to allow submersed washing after soldering. When washing, follow the guidelines given below: 1. Clean with alcohol solvents. Do not use chlorine solvents or water. 2. When using ultrasonic cleaning in two- or three-tank systems and do not clean for more than one minute at a time or for more than three minutes total. 3. Do not apply external force to the Switch while washing. 4. Do not wash immediately after soldering. If possible, allow components to stand for at least three minutes before washing. 5. The Switch cannot be used where subject to direct contact with water. Normal temperature Temperature % ( C) 60 to 90 s 20 s 30 s max. Time (s) Note: The above heating curve applies if the thickness of the circuit board is 1.6 mm. 4 B3S Key Switch Packing Key Switches are packed on tape as shown below.
