Circuit board with quality identification tag and identification method thereof

Abstract

The invention provides a circuit board with a quality identification tag, and the circuit board with the quality identification tag includes a primary board, plural secondary boards, two first main identification points and plural first sub identification points, wherein the primary board includes a product area and two first identification areas, the two first identification areas are arranged on both sides of the product area, the plural secondary boards are arranged in the product area, the two first main identification points are respectively arranged in the two first identification areas, of the plural first sub identification points are equivalently arranged in the two first identification areas, and each two of the first sub identification points are arranged relatively on both sides of each sub secondary board. When at least one of the secondary boards is a bad product in the product area, the first main identification points are covered with tags; when the secondary boards are bad, the first sub identification points relative to both sides of the secondary boards are covered with the tags. The circuit board with the quality identification tag and an identification method of the circuit board with the quality identification tag can shorten the time of classifying different qualities of boards, improve finished product yield and activation of a drilling crew, and meet the identification conditions of different kinds of production devices over bad boards.

Description

technical field [0001] The invention relates to a circuit board design, in particular to a circuit board design with quality identification marks and an identification method thereof. Background technique [0002] At present, the circuit boards shipped by the manufacturers of circuit boards generally do not have marking areas designed to identify the quality of the circuit boards. Draw a line to indicate that the corresponding sub-board is defective. Such as figure 1 As shown, it is a circuit board with a quality identification mark in the prior art. There are 6 sub-boards on the circuit board 1. If the sub-board ② is a defective product, we will draw a line L on the surface of the sub-board ②. To show that the sub-board ② is a defective product. [0003] However, when the circuit board 1 needs to be mounted on its surface later, the existing part mounting equipment (mounting machine) and automatic printing machine on the market cannot identify defective parts according t...

AI Technical Summary

Problems solved by technology

[0003] However, when the circuit board 1 needs to be mounted on its surface later, the existing part mounting equipment (mounting machine) and automatic printing machine on the market cannot identify defective parts according to the mark L on the circuit board 1. The position of the sub-board, so that the machine cannot correctly obtain good products for production

In this way, it is easy to further cause the machine to mount and print defective products, thereby affecting the production yield of the product. At the same time, it takes a lot of manpower to classify these circuit boards with defective sub-boards before leaving the factory. quite a waste of time
