How to soldering is easy


Friends say that Electronic Project I presented is not working. But any project in The Our Electronics Projects Tested through the creation of me. Therefore guarantee that the It certainly worked.

When I was a beginner. Most projects does not working because my solder joint is bad. As Figure below.

Bad solder join

It may cause an electric current does not flow through the circuit devices. Or sometimes, I soldered too much until a short circuit. These are all the the reasons the project is not working.

Good soldering requires great skill. Experience and Which has How to as follows.

1.You should bend slightly device’s leg.
01 You should bend slightly device's leg

2. Bring a soldering iron tip to touch at the device’s leg and pad for about 3-5 seconds. To absorbs heating from tip of iron to them approximately 300 ° C.

In normal use you should setting watts at 20watts for beginner because not too hot when use for semiconductor part.

3.Now at the leg of component will very hot like iron tip. So you can feed a lead solder to touch the component’s leg until the solder melt full pad.
Do not feed solder to tip of iron.

4. Then pull solder out, and still tip at solder joint for 3 second.

6. Use wire cutters to cut each wire just above joint, be careful cut into solder joint.
