使用量が増加し、半田付コストが高くなるという問題点
があった。This conventional rosin-based flux, when a metal material is put in a solder bath, causes less scattering of solder balls during soldering and less adhesion to the metal material.
After soldering, in order to remove the flux residue, it had to be washed with an organic solvent such as CFC or 1.1.1 trichloroethane. The cleaning with the organic solvent has a problem in terms of environmental management, and since the solvent is highly volatile, the amount used increases and the soldering cost increases.

不良等を発生させるという大きな問題点があった。Next, since the water-soluble flux is washed with water after soldering, the soldering cost can be greatly reduced as compared with the case of using the rosin-based flux, and the environmental management problem can be solved. There is a big problem that the balls are scattered so much that the solder balls adhere to the portions of the metal material that do not need to be soldered to cause a short circuit defect.
