If you want to solder the right way, without getting frustrated the iron, and get professional results, follow our guidelines.

Why is Fume Extraction important?

Solder fumes and gases are one of the main causes of health problems in an industrial workplace. Having correct extraction systems installed is not only important to meet workplace regulations, but also to ensure the safety and health of your operators.

To protect your employees and their health, keep the following suggestions in mind!

How to rework heat sensitive components

The main factors contributing to cracking Multilayer Ceramic Capacitors (MLCC) are the brittleness of the ceramic materials and the thermal and mechanical stresses associated to SMT assembly processes.

During manual rework, one of the main risks for these MLCC is the thermal shock that takes place when the soldering tip touches directly the component. When this happens, all the heat on the tip is transferred without control to the capacitor creating cracks on it.

In order to mitigate damage to MLCCs, manufacturers have been providing guidelines to reduce the risk of cracking like applying the soldering tip only to the pad so the heat is transferred to lead through the solder alloy, preheating the chip to more than 150°C to reduce the temperature gradient that takes place as soon as the soldering tip is applied, etc.

What is the correct temperature for soldering?

In most cases, the factor that most influences the duration of a tip is the working temperature.

Before the ROHS regulation (Restriction Of Hazardous Substances) came into effect on the 1st July 2006, solder wire that contained lead was permitted. After this date the use of lead was prohibited (as well as other substances) in all equipment and processes except the following: medical apparatus, monitoring and surveillance equipment, measuring instruments and equipment specifically designed for the military and space industry as well the car sector (car control systems, airbags, etc.), rail transport, etc.

The special characteristic of the most common lead alloys is that the fusion occurs at around 180°C. With the most common lead-free alloys this happen approximately at 220°C. So the difference of 40°C meant it was necessary to increase the temperature of the solder tool to achieve a solder joint in the same length of time (if soldering time is increased, then the components and the printed circuits may be damaged) and this reduced the life of the tips and increased oxidation.

Soldering: The Dos and Don’ts

Soldering may seem complicated and difficult but with a little practice it can become quite  simple. Nothing can substitute experience when soldering, but our tips will help you master this technique quickly. So read on!

In this post we’ll take you through the various dos and don’ts you need to know about soldering.

Be careful not to apply too much pressure

❌ Don’t apply too much pressure with the tool on the PCB or the parts being soldered. It will not solder the joints more quickly and will only damage the long-lasting plating and even ruin the finest tips.

How to extend the life of tip

If you are experienced in hand soldering, you will know that the tip is the most essential part of the tool. While the soldering iron holds and heats the tip and controls performance, the tip has the most important job of transferring heat efficiently and reliably to the solder joint. Inadequate or improper tip maintenance and use are principle causes of soldering problems.
