Laser Marking of ECC 200 2D Matrix Codes on Printed Circuit Boards

Makers of electronic gadgets, from home sound hardware to car keyless passage frameworks, are progressively looking for a dependable, savvy strategy for particularly recognizing and following items through the assembling cycle, deals circulation and after-deal guarantee confirmation. An independent, robotized following framework necessitates that a lasting, machine-coherent code be connected to an inward printed circuit board to interestingly distinguish every item. The code must be sturdy enough to endure producing forms including wave bind and board cleaning, must not influence circuit execution, and must store data in the little space accessible on land cognizant printed circuit sheets. printed circuit board manufacturers

The 2D lattice code gives a way to store alphanumeric character strings in little regions of the printed circuit board. Laser stamping innovation gives a technique to forever applying 2D lattice codes to most board substrates. The high-goals and high-precision of shaft directed laser checking frameworks gives the way to make very much characterized, high unwavering quality codes paying little respect to code estimate. Laser checking additionally furnishes the client with a PC controlled stamping process for simple usage into computerized item following frameworks.

ECC 200 2D Matrix Codes

Two-dimensional symbologies encode data as a checkerboard example of on/off cells. Explicit preferences of Data Matrix codes over ordinary 1D standardized tags include:

· Encode data carefully, instead of the simple encoding of information in traditional standardized tags.

· Can suit low-differentiate printing specifically on parts without requiring a mark

· Offer extremely high data thickness – the most astounding among other basic 2D codes, which implies that you can put a great deal of data in an exceptionally little region.

· They are scaleable, which implies that you can print them and read them in different dimensions of amplification – just constrained by the goals of the accessible printing and imaging systems.

· Due to the high data thickness characteristic to Data Matrix codes, they additionally offer inherent blunder revision procedures which permit completely recouping the message encoded in a Data Matrix image regardless of whether the imprint is harmed and absent as much as 20% of the image.

· They are perused by camcorders rather than a checked laser bar utilized for perusing regular standardized identifications, which implies that they can be perused in any introduction.

ECC 200 Data Matrix is the most well known 2-D symbology with broad use in car, aviation, gadgets, semiconductor, therapeutic gadgets and other assembling unit-level discernibility applications. Information Matrix codes are regularly not supplanting ordinary straight standardized tags, however are being utilized where conventional scanner tags were excessively huge, did not give adequate capacity limit, or were indistinguishable.

Information Matrix Code Structure

The 2D framework codes show up as a “checkerboard” with the individual squares (cells) in either on (white) or off (dark) state. The code comprises of four particular components.

· The Finder “L” Pattern comprises of a strong line of cells along the left edge and base of the code that situates the peruser to the design of the 2D code.

· The Clock Track is a grouping of on/off cells along the correct edge and best of the code that assigns the line/segment tally to the peruser.

· The Data Region is the example of highly contrasting cells inside the L design and the clock tracks that contain the alphanumeric substance of the code.

· The Quiet Zone around the code must be free of any highlights that might be noticeable to the peruser. The tranquil zone ought to be no less than two lines/segments wide for codes built of square cells. The tranquil zone ought to be no less than four lines/segments wide for codes developed of roundabout cells (spots).
