Data Matrix is a two-dimensional matrix symbology consisting of black and white square modules arranged in both a validate or rectangular construction. The ECC 200 version of the symbol utilizes Reed-Solomon error equity to ensure information reliability. data Matrix was invented by means of RVSI Acuity CiMatrix. A Data Matrix token culpability keep upto 2335 alphanumeric characters.
Applications
The most popular applications for Data Matrix are marking of small items such as whole circuits and printed circuit boards. these applications actualize avail of the code’s ability to encode approximately fifty characters of data reputation a symbol 2 or 3mm square and the fact that the credo guilt be read with only a 20 percent contrast ratio.
Benefits
Data Matrix is designed to pack a lot of information in a very small space. Since the information is encoded by means of absolute dot position rather relative fleck position, it is not now sensitive to printing defects as are traditional barcode.
Limitations
Specialized 2D barcode scanners with data Matrix help are required for reading Data Matrix.
Technical Specifications
Data Matrix encodes information ropes a machine-readable binary code that is dynamically variable influence size, layout also density. The writing scheme has a high level of redundancy hold back the data „scattered” throughout the symbol. This allows the badge to perform read correctly even if part of it is missing. The binary code is formed as a matrix. each binary code device has two adjoining sides printed as solid bars, while the remaining adjacent sides are printed as a series of equally distributed square dots. These patterns are used to determine the size, the orientation and the printing density of the symbol.
two main subsets of Data Matrix symbols exist. capital subset is the conventional coding for error correction that changed into used in the initial installations of Data Matrix systems. These versions are referenced from ECC-000 to ECC-140. The second subset is referenced as ECC-200 and uses Reed-Solomon error correction techniques. ECC-000 to 140 symbols all conclude an odd number of modules along each brief side. ECC-200 symbols opine an even work in of modules on each side. Maximum data capability of an ECC-200 symbol is 3116 numeric digits, or 2335 alphanumeric characters, in symbol 144 modules.
Additional Information
The Electronic Industries arrangement has picked information Matrix as its standard for labeling of small electrical components. The symbology has also been adopted through the automobile Industry Action Group for the gander of automobile parts, as well as by the semiconductor industry for the identification of semiconductors also semiconductor wafers.
