1. Temperature Control Maintaining the correct temperature during the soldering process is essential for achieving high-quality solder joints. Insufficient heat can lead to poor solder flow and weak connections, while excessive heat can cause damage to components and the PCB itself. Recommended Soldering Temperatures Component Type Temperature Range Through-hole 300-350°C […]

1. Cold Solder Joints Cold solder joints occur when the solder does not melt completely, resulting in a weak and unreliable connection. This can happen when the soldering iron is not hot enough, the solder is of poor quality, or the soldering time is too short. To avoid cold solder […]

What is an Air Quality Sensor? An air quality sensor is a device that measures the concentration of various pollutants in the air, such as particulate matter (PM), volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen dioxide (NO2), and ozone (O3). These sensors use different technologies to detect and quantify […]
