What’s Thermal Stability in PCB?   A Tantalum Capacitor or Tantalum Electrolytic Capacitor is an electrolytic capacitor, a passive component of electronic circuits. It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide …

Tape and Reel is a SMD components‘ packaging, which enables SMT placement machines to pick and place thousands of components per hour with a very high degree of accuracy. Tape and Reels are used for packing those small liked-shaped components, …

What’s TBGA Package?   Tape Ball Grid Array (TBGA) packages are a family of electronic chip carriers that utilize circuitized flex (tape) as the die carrier mounted to a printed circuit card or board (PCB). Previously this family of packages …

True chip-size package (TCSP), package is same die size as silicon. The same as TDSP

What Is Td in PCB?   Td (Decomposition Temperature) is the temperature at which a PCB material chemically decomposes (the material loses at least 5% of mass weight), which is determined as per IPC-TM-650 Method 2.4.24.6. Like Tg, Td is …

What’s TDFN Package?   Thin Dual Flat No Leads Package (TDFN) is a very small and thin square-shaped or rectangular surface-mount plastic package with no leads. Instead of leads, it uses metal pads along two sides of the package body …

Time Domain Reflectometer (TDR) is a device that a board house uses to measure characteristic impedance of conductors on a PCB for ensuring an accurate board fabrication for controlled impedance. We always call it as PCB TDR Measurement. How PCB …

TDR stands for Time Domain Reflectometer. When using Controlled Impedance in a PCB a TDR test is used to verify the specific impedance requirements as needed.

TDSP (True Die-Size Package) is a one of chip scale packages (CSP),  the same as TCSP (True Chip-Size Package).

In printed circuit boards, Teardrops are typically drop-shaped features at the junction of vias (teardrop vias) or contact pads (teardrop pads) and traces (teardrop traces). While a typical shape of a teardrop is straight-line tapering, they may be concave. This …
