1. Alloys used in solder paste: 96, 5Sn/3, 5Ag Melting point is 221°C95, 5Sn/4, 0Ag/0, 5Cu Melting point is 217°C
2. Alloy solder used in wave soldering and hand soldering: 99, 3Sa/0, 7Cu melting point is 227 ° C
(In terms of materials, several new solder pastes have been put on the market, but they cannot replace the existing lead-tin solders. They all need to be adjusted accordingly. The main difference between the new solder pastes and the traditional solder pastes is that the melting point is relatively high. High, commonly used lead-free solder paste melting point is usually 217 ° C -225 ° C)
