List of integrated circuit abbreviations
Here is the List of integrated circuit abbreviations used commonly in the electronic industry.
Baking
Moisture from atmospheric humidity enters permeable packaging materials by diffusion. The baking will force out the absorbed moisture and shall be performed with a hot air oven adapted for baking components and PBAs.
BGA
Ball Grid Array is a package type with the bottom side covered (or partly covered) with solder bumps forming a grid pattern.
BGA-repair machine
BGA-repair machine is equipment for repair of e.g. BGA/CSP/QFN components with top and bottom heat and possibilities to have excellent control of alignment, temperature, airflow, and time.
CBGA
Ceramic Ball Grid Array is a BGA with a ceramic substrate and often high temperature alloy bumps that do not melt during normal reflow soldering.
CSP
Chip Scale Package; a component with about the same size of the chip area as the packaging area. This component has most often solder bumps as an interconnection to the PCB.
Delta T (ΔT)
The difference between the highest and lowest temperature is referred to as Delta T (ΔT).
INC
Intermetallic compounds consist of a homogenous phase of two or more materials that form during soldering and grow by time and heat after soldering and during a repair.
LGA
A land Grid Array is most often referred to as a BGA without bumps, in other words, a package with an array of soldering pads on the substrate bottom side providing electrical and mechanical connection to the PCB.
Liquidus
The temperature at which a solder starts to become molten (vs. solidus); normally for lead-free alloys the liquidus is 217°C -220°C
MLF
Micro Lead Frame is a near CSP size package with a lead frame substrate. This package uses perimeter soldering pads on the bottom of the package to provide electrical and mechanical contact to the PCB. The package also often is thermally enhanced by having the die attach paddle exposed on the bottom of the package surface.
PBA
Printed Board Assembly (assembled board)
PCB
Printed Circuit Board (bare board)
Pin-Through-Hole assembly
Pin-Through-Hole is a method of assembling a component on a printed circuit board substrate, utilizing pin-through-hole connections.
PGA
A pin Grid Array is a package type with pins arranged in an array on the bottom side of the package.
PLCC
Plastic Leaded Chip Carrier is a package type with “J-leads”. The pitch is always 1.27 mm.
QFN
Quad Flat No leads is a name of the family of square components with soldering pads on the underside as connections to the PCB.
QFP
Quad Flat Package is a package with gull-wing formed leads extending from each of the four sides.
Repair
The measure is taken when a fault has occurred in order to restore the original electrical function or mechanical performance of a printed board assembly.
Reflow cycle
The Reflow cycle is defined, in this document, as when hot air, either by hot air gun or BGA repair machine, is used and the temperature on the board in any area is exceeding the solder liquidus temperature (normally 217-220°C).
Rework
Action is taken to reprocess non-complying articles through the use of original, or alternate equivalent processing, in a manner that assures compliance of the article with applicable drawings or specifications.
SOIC
Small Outline Integrated Circuit is a square or rectangular package type with gull-wing formed leads extending from two opposite sides.
SOT
Small Outline Transistor is a rectangular package with three gull-wing leads; two at one side and one at the opposite side (It also exists SOT packages with four leads and with five leads of which one lead is larger and used for heat transfer).
WLP
Wafer Level Package is a package type where the wafer fabrication process has been extended to include device interconnection and device protection processes. A WLP is a protected chip with, most often, solder bumps as interconnects.
