Manual soldering is the most common process in SMT processing lines. But the welding process should pay attention to some safety measures in order to work more efficiently.
Staff need to pay attention to the following points:
1. Due to the distance from the soldering iron head 20 ~ 30cm at the concentration of chemical substances than the recommended value is much smaller, so when welding should maintain the correct operating posture, the tip of the soldering iron head from the tip of the operator’s nose to maintain at least 20cm above the work to straighten the waist, chest sitting, do not bow operation.
2. The lead hardly evaporates, but because the operation to use the thumb and forefinger to pinch the solder wire, brazing material microscopic powder will adhere to the fingertips, be sure to develop the habit of washing hands before meals.
3. with automatic soldering machine for smt processing, SMT welding machine generated a large amount of smoke shrouded indoor. At this time, you can first open the air device, and then start the operation.
4. Because the repair and need to disassemble the welded wire, sometimes due to the elasticity of the wire and the brazing material collapse out. The bouncing pin material can cause accidental injury, so you should wear protective glasses when operating, and this must be firmly implemented.
5. No splash of brazing material should be allowed on the workbench and the surrounding ground to prevent the brazing material from sticking to the body or clothes. Clean up at least once a day so that the welding work can be done in a clean environment.
6. Due to the use of soldering flux or solvent when a lot of welding, and energized soldering iron placed on the workbench, from the perspective of fire prevention, must be equipped with a soldering iron rack, soldering iron to neatly placed, to do in order.
7. Some people often stick in the soldering iron on the excess brazing material thrown down, which is not only easy to hurt others, but also dirty the ground. Therefore, the soldering iron rack can be placed on the soldering iron head cleaner, in order to scrub. Or place a wet towel on the operating table, can also be used to wipe out the solder on the soldering iron.
8. In addition, in a relatively dry season for welding, you can wear anti-static bracelets, wear anti-static work clothes.
