Choosing the Right Soldering Iron for Building Computers

There are various types of soldering irons, all of which produce a wide range of wattage in terms of heat. The amount of wattage you need will depend on the type of project you’re working on. When it comes to building computers, it’s important to select a soldering iron that produces just the right amount of heat — too much or too little wattage could damage the circuit boards. T

Basic Soldering Irons

When it comes to building computers and working on printed circuit boards, a basic soldering iron that’s rated within the 15 W to 30 W range is the best. Any more than this range can cause damage to the components of the computer circuit board.

Soldering Irons With Higher Wattage

That said, there are times when a slightly higher wattage is allowable. Heavier computer components and thicker wires can handle a higher range. In this case, higher wattage soldering irons — which produce 40 W and more — can be used for components such as 10-gauge copper wire and larger heat sinks.

The biggest difference between soldering equipment like irons and guns is the heat source’s size. Soldering irons feature a pinpoint heat source used for precise work; on the other hand, soldering guns are less exact, yet can produce higher wattages as a result of the electrical current that flows directly through the tool.

Solder Types

A solder that is 50 percent tin and 50 percent lead features a melting temperature of 425 degrees F, whereas a solder that is 60 percent tin and 40 percent lead features a melting temperature of 371 degrees F. A further reduced percentage change in favor of tin continues to lower the needed melting temperature.

It’s important to look at the specifications for the iron you select to make sure it can generate the right amount of heat for the type of solder you’re using.
