* Soldering Conditions

Condition for Reflow

  1. Heating method

       Double heating method with infrared heater.

  2. Temperature measurement

       Thermocouple 0.1 to 0.2 Φ CA(K) or CC(T) at solder joints (copper foil surface). A heat resisting tape

       should be used for fix measurement.

3. Temperature profile

(1) The above temperature shall be measured of the top of switch. There are cases where PC board's temperature greatly differs from that of the switch, depending on the material, size, thickness of PC board's and others. Care, should be taken to prevent the switch's surface temperature from exceeding 260°C.

(2) Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is highly recommended.       

Manual Soldering

1. Consult with us for availability of TACT switch washing.

2. Prevent flux penetration from the top side of the TACT switch.

3. Switch terminals and a PC board should not be coated with flux prior to soldering.

4. The second soldering should be done after the switch returns to normal temperature. 

5. Use the flux with a specific gravity of min.0.81

Use Notes:

1. Terminals to carry our welding, if the load imposed on the terminal,  it may be relaxed, deformation and deterioration of the electrical characterisics due to the different conditions, please note that when in use

2. The use of through holes brushes circuit board and other recommended board,  due to the heart stress of change, so please pre-conditions on the welding and full recognition.

3. Welding on the set of conditions needed to confirm the actual conditions of mass production.
