If someone were to ask what the most important part of their favorite electronic device is, they are likely to point to the printed circuit board (PCB) responsible for making the device work before moving on to other components. From large motherboards to tiny chips, most of the technology that retail consumers take for granted comes down to a properly installed and calibrated PCB.

Soldering system vendor SEHO runs a Technology Center in its headquarters in Germany, in which all available machines are exhibited and demonstrated. Additionally, the SEHO Academy provides knowledge as a perfect balance of theory and practical application. In both facilities soldering fume occurs, which has damaging effects on human health, manufacturing equipment and products. That's why the company had installed several air cleaning solutions in terms of fume extraction technology. How and why they take care of clean air is the subject of this article.

This paper describes the losses from defects at the placement process in the SMT line. Two case studies of European and Taiwanese SMT manufacturers illustrate the actual losses from their defects. An evaluation method to select a pre-reflow AOI system maximizing the return on investment (ROI) is introduced. In the end, ROIs of three commercial pre-reflow AOI systems are compared to demonstrate the importance of selecting an appropriate AOI system. This paper will increase the probability that anyone installing an AOI system during the pre-reflow process will obtain a successful gain with short payback period.

The mass flow sensor, or air flow sensor is one of the important sensors of the electronic fuel injection engine. It is installed between the air filter and the intake hose to measure the intake volume of the engine cylinder and adjust the fuel ratio according to it. The mass flow sensor converts the inhaled air flow into electrical signals and sends them to the electronic control unit (ECU). As one of the basic signals to determine the fuel injection, it is a sensor that measures the air flow of the suction engine. So if you want to test it, how should you do? Let's start it.
