What is QFP chip?
What is QFP chip?
PQFP (Plastic Quad Flat Package) is a form of chip packaging. PQFP packaged chips have pins on all sides, and the total number of pins is generally more than 100, and the distance between the pins is very small, and the pins are also very thin.
What is the difference between QFN and QFP?
Quad flat package (QFP) is also a surface mount integrated circuit package. In QFP, unlike QFN, the leads extend out in a gull-wing shape (L-shaped). This provides a good footing for the package during the PCB assembly process.
What are the SMD IC types?
What Are DIP, SMD, QFP And BGA IC Packages?
- Dual-in-line package (DIP)
- Surface-mount device (SMD)
- Small-outline IC (SOIC) package.
- Small-outline package (SOP)
- Quad-flat package (QFP)
- Quad-flat no-leads (QFN) package.
- Small-outline transistor (SOT)
- Ball-grid array (BGA)
What is LQFP64?
LQFP64, plastic, low profile quad flat package; 64 terminals; 0.5 mm pitch; 10 mm x 10 mm x 1.4 mm body.

What is QFP software engineering?
(Quad FlatPack) A square, surface mount chip package that has leads on all four sides and comes in several varieties.
What does QFP stand for in electronics?
A quad flat package (QFP) is a surface-mounted integrated circuit package with “gull wing” leads extending from each of the four sides. Socketing such packages is rare and through-hole mounting is not possible.
What is BGA IC?
A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package.
What is the difference between LQFP and TQFP?
LQFP package having total height less than 1.7mm (including 1.7mm) and more than 1.2mm (no including 1.2mm), said package named Low profile Quad Flat Package. TQFP package having total height less than 1.2mm, said package named Thin profile Quad Flat Package.
What does QFN stand for?
quad-flat no-leads
Flat no-leads packages such as quad-flat no-leads (QFN) and dual-flat no-leads (DFN) physically and electrically connect integrated circuits to printed circuit boards.
What is BGA Fullform?
Ball Grid Array (BGA) is a type of Surface Mount Technology (SMT) that is used for packaging Integrated Circuits (IC). BGA contains arrays of tin balls arranged in a grid and its solder balls play a role as a connection interface between packaging IC and Printed Circuit Board (PCB).
What is the difference between QFP and QFN ICS?
There is another QFP IC type, but with a different pin structure, called QFN package. Pins on a QFN package are exposed on the bottom and sometimes on both the sides and the bottom. SMD devices such as rectangular transistors are available in SOT packages. Advanced ICs are available in BGA packages.
What are the dimensions of a QFP package?
Thin QFP packages have the package body heights (mold thickness) of 1.0 mm and of 1.27 mm. Low Profile Quad Flat L-Leaded Package LQFP packages have the package body height (mold thickness) of 1.4 mm. Small Out-line J-Leaded Package SOJ packages are characterized by J-shaped leads which are drawn out
When did the QFP component type become common?
The QFP component package type became common in Europe and United States during the early nineties, even though it has been used in Japanese consumer electronics since the seventies. It is often mixed with hole mounted, and sometimes socketed, components on the same printed circuit board (PCB).
What’s the difference between a PQFP and a TQFP?
Body sizes range from 5 mm x 5 mm to 20 x 20 mm. Copper lead-frames are used in TQFPs. Lead pitches available for TQFPs are 0.4 mm, 0.5 mm, 0.65 mm, 0.8 mm, and 1.0 mm. PQFP, or plastic quad flat pack, is a type of QFP, as is the thinner TQFP package. PQFP packages can vary in thickness from 2.0 mm to 3.8 mm.
