Elements that indicate or influence instrument performance. A first indication of the performance of the instrument is the accuracy or precision of the instrument, such as its response time, resolution, and range. A second indication of performance is the technical performance of the instrument, such as its power level, the electromagnetic interference, and transient voltages. A third indication of performance are environmental factors that can influence instrument performance, such as humidity, operating temperatures, or dust.

During automated optical inspection (AOI), printed circuit boards (PCB) or surface-mount devices (SMD) are inspected by means of an automated optical inspection machine. During each automated optical inspection test, dozens of images are captured with a special camera and compared to previous assembled boards to detect any anomalies.
Standards and guidelines with regards to the use and manufacture of electronics and printed circuit boards. These regulations provide rules and guidelines on topics such as general safety rules, electronic equipment manufacture, electronic equipment testing, and qualifications.
Surface-mount technology or SMT is a method where the electronic components are placed on the surface of the printed circuit board. SMT components attached in this way are usually sensitive, small components such as resistors, transistors, diodes, and integrated circuits.
Through-hole technology or THT is a method of mounting electronic components onto the printed circuit board through inserting leads on the components into holes in the circuit board and soldering the components to the board. THT components attached in this way are usually larger than SMT components, such as capacitors or coils.
The regulations and legal provisions governing waste removal activities.
Those processes in which hardware components or systems are tested, such as the system test (ST), the ongoing reliability test (ORT), and the in-circuit test (ICT).
Microelectronics is a subdiscipline of electronics and relates the study, design, and manufacture of small electronic components, such as microchips.
The national and international requirements, specifications and guidelines to ensure that products, services and processes are of good quality and fit for purpose.
Semiconductors are essential components of electronic circuits and contain properties of both insulators, such as glass, and conductors, such as copper. Most semiconductors are crystals made of silicon or germanium. By introducing other elements in the crystal through doping, the crystals turn into semiconductors. Depending on the amount of electrons created by the doping process, the crystals turn into N-type semiconductors, or P-type semiconductors.
