Temperature transducer consisting of two dissimilar metals welded together at one end to form a junction that when heated will generate a voltage.

Thermomechanical Analysis (TMA) is a thermal analysis method in which linear dimensional change is measured as a function of temperature. TMA is mostly used to determine the coefficient of thermal expansion (CTE) before and after Tg of PCB base materials. …

What’s A Thermostat?   A Thermostat is a regulating device component which senses the temperature of a physical system and performs actions so that the system’s temperature is maintained near a desired setpoint. Thermostats are used in any device or …

What’s Thick Film Technology?   Thick Film Technology involves in the processes for depositing with screen printing method and curing with heating (or firing) method to form thick layers on substrates. In PCB manufacturing industry, this technology has two main …

Capacitor consisting of two thick-film layers of conductive film separated by a deposited thick-layer dielectric film.

What’s A Thick Film Resistor?   Thick Film Resistor is made by screen printing and firing conductive and resistive paste onto hard substrates, usually alumina (Al2O3). In thick film technology, alumina of reduced purity is used (95%) compared to thin-film …

What’s Thieving on PCB?   Thieving is the addition of “dummy” pads (Thieving Pads) across the surface of PCB that are plated along with the features designed onto the outer layers. The purpose of the process is to provide a …

What’s Thin Film?   Thin Film refers to many technologies, which are processes for depositing and processing thin layers from a few microns thick down to individual atomic layers. The thin layer materials used as the substrate and the applications …

What’s Time Constant?   Time Constant (in physics and engineering), usually denoted by the Greek letter τ (tau), is the parameter characterizing the response to a step input of a first-order, linear time-invariant (LTI) system. The time constant is the …

What Is Time to Delamination in PCB? Time to Delamination (TMA Method, IPC-TM-650 2.4.24.1) describes the method for determining the time to delamination of laminates and printed boards through the use of thermomechanical analyzer (TMA). Delamination refers to the separation …
