Surface Roughness, often shortened to Roughness, is a component of surface texture. It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface …

The lateral bending of gull-wing leads.

What’s A Switch?   A Switch is an electrical component used to control a circuit by either close (ON) or open (OFF) the circuit. When it is turned on, the circuit is complete. When it is turned off, the circuit …

What’s A Switching Transistor?   A Switching Transistor is a transistor which is used as a switch. A transistor is a 3-terminal semiconductor device that can be used for switching applications, amplification of weak signals, and in quantities of thousands …

A simplified design representing a part in a schematic circuit diagram.

What’s System-in-Package (SiP)?   System-in-Package (SiP) is a number of integrated circuits (IC) enclosed in one or more chip carrier packages that may be stacked using package on package. The SiP performs all or most of the functions of an …

What Is T260 in PCB?   T260 (Time to delamination) is the time it takes for the PCB base material to delaminate when subjected to a temperature of 260°C through the use of a thermomechanical analyzer (TMA). The delamination refers …

What Is T288 in PCB?   T288 (Time to delamination) is the time it takes for the PCB base material to delaminate when subjected to a temperature of 288°C through the use of a thermomechanical analyzer (TMA). The delamination refers …

Tape-Automated Bonding (TAB), a variation of COF, where a flip chip is mounted directly to a flex circuit without the use of bonding wires. Used by LCD driver ICs. TAB technology is a process that places bare integrated circuits onto …

Tab Rout is most commonly used when a single PCB is duplicated several times in an array. Tab Rout arrays will leave a small tab on all four sides of the board attached to the other boards or to rails.
