Tools for Electronics

There are many tools for electronics but here I will give some important components which every electronic lover should have

Soldering iron       

 

For electronics work the best type is one powered by mains electricity (230V in the UK), it should have a heatproof cable for safety. The iron's power rating should be 15 to 25W and it should be fitted with a small bit of 2 to 3mm diameter.

Soldering iron stand

 

You must have a safe place to put the iron when you are not holding it. The stand should include a sponge which can be dampened for cleaning the tip of the iron.

Reel of solder (soldering wire)

 

The best size for electronics is 22swg (swg = standard wire gauge).

Desoldering pump (solder sucker)

 

A tool for removing solder when desoldering a joint to correct a mistake or replace a component.

Solder remover wick (copper braid)

 

This is an alternative to the desoldering pump shown above.

Side cutters

 

For trimming component leads close to the circuit board.

Wire strippers

 

Most designs include a cutter as well, but they are not suitable for trimming component leads.

 Screwdriver box

 

 Soldering flux

 

These are must components for electronics though there are many other minor components and your can buy these from a electronics shop.
