TO Package family consists of many types of packaging solutions for transistors and similar discrete devices as well as simple ICs with low pin counts. The structures of TO packages vary widely, from expensive metal can enclosures to low-cost plastic-molded …

What’s A Toggle Switch?   A Toggle Switch is a type of electrical switch that is actuated by moving a lever back and forth to open or close an electrical circuit. There are two basic types: Maintained contact: changes its …

A soldering defect condition observed after reflow soldering, in which leadless devices such as chip resistors or capacitors stand on their end, with only one edge soldered to lands on the circuit board, resembling a tombstone. Also referred to as …

The primary side of a PCBA, usually containing the most complex or major components. The top side of a PCBA having some or all through-hole components (Assembly Types II and III) is the side with the through-hole component bodies, and …

TPI (Thermoplastic Polyimide) features polyimide film, coated on both sides with a B-staged modified polyimide adhesive or polyimide adhesive. TPI is similar to Dupont bondply, which coated on both sides with proprietary B-staged modified acrylic adhesive. You also can think …

What’s TQFN Package?   Thin Quad Flat No-lead (TQFN) is a very small and thin square-shaped or rectangular surface-mount package with no leads. Instead of leads, it uses metal pads around the periphery of the bottom of the package body …

What’s TQFP Package?   Thin Quad Flat Pack (TQFP) is a surface-mount IC package with gull wing leads on all four sides of the package body. It is basically a thinner version of the MQFP and LQFP.   This package …

In electronics, a signal trace on a printed circuit board (PCB) is the equivalent of a wire for conducting signals. Each trace consists of a flat, narrow part of the copper foil that remains after etching.

Trace on PCB.

What’s A Transducer?   A Transducer is a device that converts energy from one form to another. Usually, a transducer converts a signal in one form of energy to a signal in another. Transducers are often employed at the boundaries …
