How to solder resistors on rigid-flex boards [Copy link]

The circuit arrangement of the rigid-flex board requires resistors in some 'fortresses'. Soldering technology is used to realize resistors in the rigid-flex board. How to solder resistors on the rigid-flex board? Let's take a look at the welding of the rigid-flex board?

1.Insert the resistor into the small hole on the front of the rigid-flex printed circuit board and leave a 3-5MM long pin;

2.Solder the resistor to the copper foil on the back of the rigid-flex printed circuit board. It is best to control the welding time within 2-3s;

3. Check the 10 solder joints on the rigid-flex board and re-solder those that do not meet the soldering requirements;

4. After the operation, remove the resistor and turn off the power of the soldering iron.
