A soldering iron is a hand tool used in soldering. It supplies heat to melt the solder so that it can flow into the joint between two work pieces. So only the best will do as this piece of equipment is vital to carry out Laptop Motherboard Repairs.

Temperature Controlled Irons Vs. Normal Simple Irons

Simple irons reach a temperature determined by thermal equilibrium, dependent upon power input and cooling by the environment and the materials it comes into contact with. A small iron will lose temperature while soldering a connection, thus reducing efficiency and quality of the joint.

More advanced irons for use in electronics have a mechanism with a temperature sensor and method of temperature control to keep the tip temperature steady. Temperature-controlled irons comprise of a head with heating element and tip, controlled by a base called a soldering station, with control circuitry and temperature adjustment and sometimes display.

JBC Soldering Station

A soldering station, invariably temperature-controlled, consists of an electrical power supply, control circuitry with provision for user adjustment of temperature and display, and a soldering iron or soldering head with a tip temperature sensor. The station will normally have a stand for the hot iron when not in use, and a wet sponge for cleaning. It is most commonly used for soldering electronic components.

Tips / Bits / Cartridges


If you click on the image above, the JBC solder station has a very fast and efficient way of changing the tip on the soldering iron to suit the soldering situation.

Most soldering irons for electronics have interchangeable tips, also known as bits or cartridges, that vary in size and shape for different types of work. We have found JBC soldering stations to be fast, efficient, reliable and safe.

Tip selection depends upon the type of work and access to the joint; soldering of 0.5mm pitch surface-mount ICs, for example, is quite different from soldering a through-hole connection to a large area.

Soldering Tweezers

For soldering and desoldering small surface-mount components with two terminals, such as some links, resistors, capacitors, and diodes, soldering tweezers are used. The main purpose of the soldering tweezers is to melt solder in the correct place.

When the iron tip oxidises and burnt flux accumulates on it, solder no longer wets the tip, impeding heat transfer and making soldering difficult or impossible; tips must be periodically cleaned in use. Such problems happen with all kinds of solder, but are much more severe with the lead-free solders which have become widespread in electronics work, which require higher temperatures than solders containing lead. Exposed iron plating oxidises; if the tip is kept tinned with molten solder oxidation is inhibited. A clean unoxidised tip is tinned by applying a little solder and flux.

A wetted small sponge, often supplied with soldering equipment, can be used to wipe the tip. For lead-free solder a slightly more aggressive cleaning, with brass shavings, can be used.  We provide each engineer with brass shaving balls, as shown above, they have proven to be be the best in keep tips clean and operating at an efficient level.
