One, research engine |
|
With the increase of human awareness of environmental protection, the use of lead in the electronics industry is increasingly restricted. Lead-free solder has become an inevitable development trend in the electronics industry. In order to cooperate with the popularization and promotion of lead-free solder, the company has conducted in-depth research on lead-free solder flux, and then developed LC-700 and LC-702 series of lead-free solder flux. |
|
|
Two, application |
|
LC-700 and LC-702 are specially designed for the lead-free solder process, and are formulated for the characteristics of lead-free solders such as high melting point, easy oxidation, and poor solder fluidity. It is widely used in all kinds of high-precision electronic industry PCB board welding such as communication, audio, DVD, air conditioner, computer, etc. The operation procedure can be used for foaming or spraying, because the flux has extremely high insulation resistance and wetting It is also an ideal substitute for traditional no-clean flux. |
