BBIEN SAC0307 high temperature lead free solder wire is ideal used for precious electronic, silver contain product, medical electronics, high-temperature electric machine, phone motherboard, printed circuit board (PCB), LED and SMT technique,as well as high-precision electronics circuit board. ,

How to use tin-bismuth solder wire:
Step1:Prepare the solder station or gas woldering gun

Step2:Before welding, please clean electric solder iron,remove the tin dross, and then set the thermostat temperature reach to SACX0307 solder wire's preheat temperature: 150 degrees to 180 degrees Celsius.
Stay automatic temperature rise to 227 degrees Celsius,which can be used to welding solder joints (before welding, you can take a small experiment, to ensure that the melting temperature can melt tin copper silver wire(Sn99Ag0.3Cu0.7), in order to avoid again when welding produce needless trouble).

Step 3:When the solder iron temperature or gas soldering gun temperature reaches 227 degrees Celsius, heating the Sn99Ag0.3Cu0.7 no clean core solder wire and used for circuit board solder joints (or other device being welding) welding heating.
When finishing to melt solder wire,it will get the fully soldering joints(Note: the Sn99Ag0.3Cu0.7 solder wire welding in the process,the peak temperature at 320 degrees to 350 degrees Celsius).
