What is the soldering temperature for lead-free solder wire?

Lead-free solder wireWhat is the welding temperature? There are commonly two types of soldering we see: lead-free and leaded. The melting point of leaded solder wire is lower180℃Left and rightSAC305It has the best metal content and good welding performance.The melting point of lead-free solder wire is217-228℃BetweenSAC305The metal content is the best, followed bySAC0307Now, JJY solder Paste Manufacturer will share with you two different temperature melting points:

The melting point of lead-free solder wire

1,Sn-Cu-NiThe melting point of solder wire is225℃-227℃

2,Sn-Cu-AgThe melting point of solder wire is211℃-219℃

3,Sn-Bi-AgThe melting point of solder wire is205℃-208℃

4,Sn-ZnThe melting point of solder wire is117℃-119℃

5,Sn-CuThe melting point of solder wire is220℃-222℃

6,Sn-AgThe melting point of solder wire is221℃

The melting point of leaded solder wire

(1)63/37The melting point of solder wire is183℃

(2)60/40The melting point of solder wire is185℃-190℃

(3)55/45The melting point of solder wire is187℃-202℃

(4)50/50The melting point of solder wire is190℃-216℃

(5)45/55The melting point of solder wire is192℃-227℃

(6)40/60The melting point of solder wire is194℃-238℃

(7)35/65The melting point of solder wire is198℃-247℃

(8)30/70The melting point of solder wire is202℃-256℃

The welding quality of lead-free welding wire depends on many factors. One of the most important factors is the setting of lead-free solder wire temperature, which is very crucial for the soldering of lead-free solder wire. To determine the lead-free solder wire temperature, it should be based on PCBConventional solder joints should be selected based on factors such as plate thickness, pad size, device and surrounding heat dissipation area350℃When the temperature on the left and right meets the requirements, the size of the soldering iron tip should be as large as possible. It should be selected when the thermal efficiency is high350℃Left and right.
