Polyimide (PI) is a polymer of imide monomers. Polyimides have been in mass production since 1955. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles. …

What Is A Package on A Package (PoP)?   Package on Package (PoP) is an integrated circuit (IC) packaging method to combine vertically discrete logic and memory ball grid array (BGA) packages. Two or more packages are installed at top …

1. n. A developed image of photoplotted film, where the areas selectively exposed by the photo plotter appear black, and unexposed areas are clear. Board houses work from positives, and a photo plotter produces positives, thus one set of positives …

What is Potential Difference?   Potential Difference is the voltage difference between two points which will cause current to flow in a closed circuit. It can be simply defined as the difference of electrical potential between two points. When two …

Energy that has potential to do work because of its position relative to others.

What’s Potentiometer?   Potentiometer is a variable resistor with three terminals. Mechanical turning of a shaft can be used to produce variable resistance and potential. For details, please refer to the glossary Variable Resistor.     In PCB manufacturing, sometimes, …

Power Supply in PCB   Power is the amount of energy transferred or converted per unit time. The SI unit is watt (W), equal to one joule (J) per second (s). The dimension of it is energy divided by time. …

What is a Power Amplifier?   A Power Amplifier is an electronic amplifier designed to increase the magnitude of power of a given input signal. The power of the input signal is increased to a level high enough to drive …

The distribution (or concentration) of power dissipation of electronic components and interconnections across the surface area of a PCA.

What is Power Dissipation?   Power Dissipation is the process by which an electronic or electrical device produces heat (energy loss or waste) as an undesirable derivative of its primary action. You can understand that the amount of heat energy …
