Board soldering considerations

Solder board considerations:

1. Round welding order. The order of component soldering is as follows:  resistors, capacitors, diodes, transistors, integrated circuits, high-power tubes, the order of other components from small to large.

 

2. Both the chip and the base are oriented. When soldering, strictly follow the direction indicated by the notch on the PCB, so that the chip, the base and the PCB are all corresponding to the gap.

 

3. When soldering, make tin around the solder joint to firmly solder it to prevent solder joint.

 

4. When soldering a circular polar capacitor, the general capacitance value is relatively large. The pin of the capacitor is a short length and the long leg corresponds to the hole where the "+" sign is located.

 

5. Before the chip is mounted, it is best to bend the pins on both sides slightly to make it easier to insert into the corresponding socket of the base.

 

6. The potentiometer is also directional, with the knob corresponding to the protruding direction on the PCB.

 

7. When taking the resistor, after finding the required resistance, take the scissors to cut the required number of resistors and write the resistor to find it.
