Regulations on soldering temperature and welding time of electric soldering iron
Regarding the regulations on the welding temperature and welding time of the electric soldering iron, the welding time of the electric soldering iron is 2s/point. It is best not to exceed 3s/point. The welding temperature of the electric soldering iron has a required temperature range according to different objects to be welded. Different, there are regulations on the soldering temperature and time of the electric soldering iron.
Regulations on soldering temperature and welding time of electric soldering iron
Soldering time of electric soldering iron:
2s/point is the best, it is best not to exceed 3s/point
soldering iron soldering temperature
1. The temperature of the soldering iron for soldering patches, coding switches and other components is 343±10℃;
2. The soldering iron temperature for welding color ring resistors, ceramic capacitors, tantalum capacitors, short-circuit blocks and other components is 371±10℃;
3. When repairing general components (including IC), the soldering iron temperature should be within 350±20℃;
4. When repairing power modules with thick pins, transformers (or inductors), large electrolytic capacitors and large-area copper foil pads, the soldering iron temperature should be 400±20°C.
5. The temperature requirements for soldering irons in SMT, assembly and soldering inspection, and mobile phone production lines are strictly in accordance with the temperature requirements in the production station inspection and welding operation instructions;
6. Lead-free special soldering iron, temperature is 360±20℃.
When welding and disassembling patch components, you need to wear an electrostatic ring. An electrostatic ring is also called an electrostatic wristband. It is generally a wide and tight band made of conductive fiber.
Main function: Protect electronic components from being broken down by static electricity. When using it, be sure to connect the ground wire, otherwise it will be "in name only" and will not work.
