Electronic Glossary

A mass soldering technique in which high-temperature vapor, condensing on the solder joints of a PCB, is the heat-transfer medium.

A solder process using vaporization of a liquid as heat source.

What’s A Variable Capacitor?   A Variable Capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio …

What’s A Variable Resistor?   A Variable Resistor  changes resistance from zero to a certain maximum value. They are commonly used as volume controls and in voltage regulators. They can be used to adjust circuit elements (such as a volume …

Almost all integrated circuits (ICs) have at least two pins that connect to the power rails of the circuit in which they are installed. These are known as the power-supply pins. However, the labeling of the pins varies by IC …

What’s VFBGA Package?   Very Thin Profile Fine Pitch Ball Grid Array (VFBGA) is a thinner version of the TFBGA package. Like all BGA packages, VFBGAs use solder balls that are arranged in a grid or array at the bottom …

VIPPO is the abbreviation of Via in Pad Plated Over. As the speed signal, performance requirements, and routing density increasing, the use of advanced technology of PCB is becoming more and more important, as a result, many BGA place holder area …

What Is Visual Inspection in PCB and PCBA?   PCB Visual Inspection is to inspect whether the printed circuit board, or its specimen/coupon, and PCB assembly (PCBA) meets customer’s requirements and related quality acceptance standards either with naked eyes or …

Very Large Scale Integration.

What’s Volt?   The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. It is named after the Italian physicist Alessandro Volta (1745–1827). One volt is defined as the electric potential between …
