            ★Loose reflow process window
            ★Excellent wetting and tin eating ability
            ★Low bubble and void ratio
            ★The adhesive force can be maintained for a long time
            ★Transparent residue

            Scope of application

            Suitable for SMT industry PCB surface resistance, capacitance, IC and other electronic components welding

            2. During continuous printing, the viscosity changes little, and the steel mesh has a long operational life. It will not dry after more than 8 hours, and still keeps good     printing effect;

            3. After several hours of printing, the original shape is still kept, basically no collapse, and the chip components will not be offset; 

            4. It has excellent weldability and can show proper wettability in different parts; 

            5. It can adapt to the requirements of different grades of welding equipment. It does not need to complete welding in nitrogen charging environment, and it can still perform good welding performance in a wide range of reflow furnace temperature;

            6. After welding, the residue is very little, the color is very light, and the insulation resistance is high, which will not corrode the PCB, and can meet the requirements of free washing;
