Produsen elektronik, sistem audio rumah dalam sistem keyless entri otomotif, semakin mencari cara yang dapat diandalkan dan nyaman untuk mengidentifikasi dan melacak produk melalui siklus manufaktur, distribusi penjualan dan setelah-penjualan jaminan otentikasi. Otonom, sistem pelacakan otomatis membutuhkan permanen, kode mesin terbaca untuk menerapkan sirkuit tercetak tunggal unik mengidentifikasi setiap item. Kode harus cukup tahan lama untuk proses produksi, termasuk gelombang solder dan membersihkan dewan tidak pantas untuk mempengaruhi kinerja dari rangkaian, dan informasi harus disimpan dalam ruang kecil di papan properti.

The-aware 2D PCB matrix code provides a means to store alphanumeric strings in very small part of CAP. Laser marking technology provides a method for applying 2D matrix continues for most board substrates. High resolution and high precision laser beam control marking systems provides the means to create well-defined, codes of high reliability regardless of the size of the code. Laser marking also provides the user of a computer-controlled marking process for easy implementation into automated monitoring products systems.

ECC CodesTwo Matrix 200 2D symbologies encode size information in the form of a chessboard of power to arrest cells. Specific advantages of Data Matrix codes over conventional 1D barcodes are: encode digital information, in contrast to the encoding of analog to traditional bar codes. Can accommodate low contrast print directly on parts without a label, offers a very high information density – the highest among the other common 2D codes, which means that a lot of information in a very small. They are scalable, which means that you can print and read at different levels of magnification – only limited by the resolution imaging and printing available.

The high density of information that are inherent Card Matrix codes, they also offer fully integrated technical correction that can restore the message encoded in a DataMatrix symbol, even if the label is damaged or missing up to 20% symbol. They are read by cameras, unlike a laser scanner for reading bar codes, which means they can be read at any orientation.ECC Data Matrix symbology 200 is the most popular 2-D with a wide use in sectors such as automotive electronics, semiconductors, medical devices, and other manufacturing applications, the unit-level traceability.

Data Matrix are generally not replace traditional linear bar codes, but are used as traditional bar codes were too big, not enough storage, or were unreadable.Data StructureThe 2D Matrix Code are displayed as a matrix board, with individual squares (cells) di (putih) or off (black) state. The code consists of four different elements. The "Finder L" model consists of a row of cells on the left and bottom of the code reader is directly available to the 2D code. The clock has run a series of on / off cells along the coast and the code than the number of row / column for the reader.

The region data is the model of the blood cells in the model B & W L-tracks and watch the contents of the alphanumeric code in them. The quiet of all code must be free of any function that may be visible to the reader. The lying area must be at least two rows / columns width for codes composed of square cells. the rest area must be at least four rows / columns range product codes of circular cells (DOTS). ECC 200 Data Matrix codes 3116 numeric, alphanumeric characters or 2335 bytes of binary information 1555 to a column of 144 144 Line Array.

More realistic symbol size of printed circuit boards may still contain a significant amount information.Laser SystemThe laser marking is the marking laser, beam shaping optics, and the direction of a laser amplifier are gebruikt.De generates a bright light, collimated beam of light at specific wavelength. For FR4 and solder mask applications, most users opt for the air-cooled CO2 laserdengan 0.640 10 nm wavelength
