(2) When dip soldering/wave soldering, the soldering condition is to be 260˚C Maximum Temperature for a Maximum Duration of 10seconds. Beware not to heat the whole crystal unit in the dip mounting process. It is recommended that the crystal be mounted in an upright position. (To prevent heat conduction directly to the body of a crystal unit.) (3) When soldering, do not apply the heat to the case body of the component as exposure to soldering heat would deteriorate the performance of the product.
