Table 1 Characteristics

Fig.1 SEM photograph of solder powder

solder paste used Pb-free spherical solde powder and

flux. Since this solder paste contains no Pb, the usage of

hazardous materials is reduced, furthermore, the

and the safe workplace are protected. As its flux residue

contains no halides, it can be remained on the PCB
