JBC is at the technological forefront of tools for soldering and rework operations in electronics. Innovation, efficiency and reliability are the key features of a wide range of products which have been designed to satisfy the most demanding requirements of professionals.

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.
