In printing, a substrate is the base material that the image will be printed on such a plastic film, glass, paper, canvas or other textile products.
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
In printing, a substrate is the base material that the image will be printed on such a plastic film, glass, paper, canvas or other textile products. Before the advent of substrate printing, the desired effect was achieved by printing labels or vinyl decals that were then applied to a substrate.
An interposer can be defined as a silicon chip that can be used as a bridge or a conduit that allows electrical signals to pass through it and onto another element. The job of an interposer is to either spread the signal to a wider pitch or take the connection to a different socket on the board.
A die, in the context of integrated circuits, is a small block of semiconducting material on which a given functional circuit is fabricated. Each of these pieces is called a die.
What Is IC Packaging? IC, or integrated circuit, packaging refers literally to the material that contains a semiconductor device. The package is a case that surrounds the circuit material to protect it from corrosion or physical damage and to allow for mounting of the electrical contacts connecting it to the PCB.
Small-Outline (SOP)
Small-outline IC (SOIC) packages are the surface-mount cousin of the DIP. On SOIC packages, each pin is usually spaced by about 0.05" (1.27mm) from the next. The SSOP (shrink small-outline package) is an even smaller version of SOIC packages.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.
The components of a package fall into two categories: package objects, the application files to be installed, and control files, which control how, where, and if the package is installed. The control files are also divided into two categories: information files and installation scripts.
There are two types of IC manufacturing technologies one is monolithic technology and other is hybrid technology. In monolithic technique, all electronic component and their interconnections are manufactured together into a single chip of silicon. Monolithic ICs are cheap but reliable.
Very Thin Shrink Small Outline Package
SMD IC. Surface-mount technology is a method for constructing electronic circuits in which the components are mounted directly onto the surface of printed circuit boards (PCBs).
The lead pitch is 2.54 mm (100 mil) and the package body is made of ceramics. Metal or glass may be used as a sealing material. Dual In-line Package (Glass Sealed) Dual In-line packages are called “CER-DIP” package. The lead pitch is 2.54 mm (100 mil), and the package body is molded with powder ceramics.
1. Short for dual in-line package, a DIP is a chip encased in hard plastic with pins running along the outside. The picture is an example of a DIP found on a computer motherboard that is soldered into place. Below is an illustration of a comparison between a DIP and a SIP not connected to a circuit board.
There are
four primary
types of Packaging. These include:
Containers are receptacles that hold, protect and organize products and materials during storage and transport.
It is used by nearly every industry, including:
- Aerospace.
- Appliance.
- Automotive.
- Beverage.
- Chemicals.
- Construction.
- Consumer goods.
- E-Commerce.
Read the serial number from the top side of the IC. The top side of the IC is facing up when the chip is standing on its pins. You may require a magnifying glass while reading the IC serial information. Open your Internet browser and enter the IC's serial number into either the Google or Yahoo search engines.
Interstitial cystitis (IC): Disease that involves inflammation or irritation of the bladder wall.
An SMD, or surface mounted device, is an electronic component that you would find on a board. An SMT, or surface mount technology, is the method of placing components (like an SMD) on the board. In electronic manufacturing services, the SMT process often works with SMDs, perhaps adding to the confusion.
Surface Mount Technology, SMT Includes:
These surface mount components come in a variety of packages, most of which are standardised to make the manufacture of the PCB assemblies using automated equipment much easier. Some of the most widely used components are surface mount resistors and surface mount capacitors.An integrated circuit, or IC, is small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory. An IC is a small wafer, usually made of silicon, that can hold anywhere from hundreds to millions of transistors, resistors, and capacitors.
The integrated circuit uses a semiconductor material (read chips) as the working table and frequently silicon is selected for the task. Afterwards, electrical components such as diodes, transistors and resistors, etc. are added to this chip in minimized form. The silicon is known as a wafer in this assembly.
PLCC - Plastic Leaded Chip Carrier. The Plastic Leaded Chip Carrier , or PLCC is a four-sided plastic package that has "J" leads around its periphery. These "J" leads occupy less board space than the gull-wing leads that other packages like the SOIC have. PLCC lead counts range from 18 to 84.
Pin numbers. The pins are numbered anti-clockwise around the IC (chip) starting near the notch or dot. The diagrams show the numbering for 8-pin and 14-pin ICs, but the principle is the same for all sizes.
