Description
Technical field
The present invention relates to a kind of circuit board and method for making thereof, refer to a kind of circuit board and method for making thereof especially with identification code.
Background technology
Enabling of bar code (Bar Code) is for saving a large amount of manpowers the earliest in department store or supermarket, material resources, unify bar code ＂ (Universal Product Code is called for short UPC) and promote and be named as ＂ by U.S. supermarket forum, be applicable to U.S., area, North America such as add, because UPC adds the area in U.S.A and causes one upsurge, so Europe is also introduced the idea of bar code and technology and has been stipulated ＂ Europe bar code ＂ (European Article Number is called for short EAN), set up EAN association by common popularization of 12 industrial countries in Europe, and the bar code idea spread to other areas, therefore bar code system begins to step into internationalization.
In the EAN/UCC system, the identification number of commodity is all changed into bar code form, showing identification number with bar code mainly is to utilize machine to do seizing automatically of data for convenience, and then improve the efficient that commodity data reads, this bar code except be used for making and logistics progress, also can be in the future as the usefulness of identification, maintenance and tracking.
See also Fig. 1, its display of commodity bar code.For making commodity can circulate in the whole world widely, no matter be to apply for the registration of or design and produce the bar code that is applied in the product voluntarily, all must follow the pertinent regulations of bar code management; Bar code is meant regularly arranged by one group, as to have different in width black and white striped at interval (promptly, the unit code) with and the sign formed of corresponding character, distinguish with bar code reader scans again in order to the symbol of representing certain commodity information, and its corresponding character is made up of one group of Arabic numerals, directly read or use to the computer dateout for the user by input equipment, and striped that should group black and white interval with and the represented information of corresponding character be identical.
The coding of bar code is followed the uniqueness principle to guarantee that bar code does not repeat in worldwide, a commodity item can only have a code, also promptly a code can only identify a kind of commodity special project, and the commodity of different size, Different Package, different cultivars, different price, different colours can only use different commercial product codes; When bar code is rendered in manufacturing industry, be the quality of keyholed back plate product, on each part, all set up bar code in the manufacture method for identification, maintenance and tracking.
With the circuit board industry should be used for see, generally be after this circuit board making is finished, in the mode of manual work pre-printed bar code is attached on the circuit board.But, printing bar code also whisker material and cost of labor, this measure for stress time efficiency and artificial expensive now, neither symbol economic benefit; Yet, not good because of the precision of printing if directly bar code is printed in this circuit board with mode of printing, and can't reach the accuracy of identification of bar code requirement.
Therefore, how one circuit board and the method for making thereof that can represent commodity item is proposed, to save the material cost and the artificial time that attaches bar code of making bar code, needing in the prior art to avoid consumption man-hour and material cost on circuit board, to attach bar code, become the problem that present industry need overcome in fact.
Summary of the invention
