What isLead-free solder paste? The solder paste we commonly see should be very common in reality. After all, it is a soldering material and many industries need to use it. Choosing the right product according to your own industry is the most important. Why do I recommend lead-free solder paste to everyone? Nowadays, most industries choose lead-free solder paste instead of the previous leaded solder paste. This is because people's awareness of environmental protection is getting stronger and stronger. As for others, It cannot be said whether it is good or bad. It also depends on your requirements and standards to measure and determine. Now, JJY solder Paste Manufacturer will introduce to you what conditions are needed for this product to burn?

What conditions are required for lead-free solder paste to burn?

1The tensile strength, toughness, ductility and creep resistance of the solder joints should all be comparable to those of the tin-lead alloy;

2The electrical conductivity and thermal conductivity after welding should both be in line with63/37Tin-lead alloy solder is close to each other;

3Reduce the cost as much as possible;At present, it can be controlled in tin-lead alloy1.5~2The price is relatively ideal;

4The newly developed lead-free solder should be as compatible as possible with various fluxes, and its compatibility should be as strong as possible;It can be used in active rosin resin type flux(RA)It can work with the support of mild and weakly active rosin flux(RMA)Or the no-cleaning flux without rosin resin will be the future development trend;

5The developed lead-free solder has good brazing performance during use with the copper base of the circuit board, or the lead-free solder plated on the circuit board, as well as the lead-free solder and other metal coatings on the pins of components or their surfaces;

6The raw materials selected for lead-free solder paste can meet the long-term and sufficient supply;

7The inspection and repair of the weld points after welding should be easy:

8It is compatible with the current equipment process in use and can operate without replacing the equipment.

This is part of the content that the editor has introduced to you. We all know that lead-free products are relatively expensive. Nowadays, most of the veteran factory leaders will consider from the perspectives of health and environmental protection. The lead-free solder paste used now is mainly environmentally friendly solder paste, that is, solder paste that has been removed from lead. Lead-free solder paste must first truly meet the environmental protection requirements and cannot remove lead. And it is necessary to take into account many issues such as the costs borne by the customers. If you still have any questions, please feel free to consult!
