Embodiment Construction
[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] An embodiment provided by the present invention: a method for detecting the production quality of a printed circuit board, specifically comprising the following steps:
[0026] S1: When cutting the material, cut the copper clad laminate into a small board that meets the size requirements of printing or the customer's finished product, then conduct size inspection and surface defect inspection, and input the inspection results into the computer, which will then store them in the cloud server;
[0027] S2: The qualified small b...

The invention discloses a printed circuit board production quality detection method. The method specifically comprises the following steps that S1, in a cutting process, a copper-clad plate is cut into small plates meeting a printing or customer finished product size requirement, then size detection and surface defect detection are performed, a detection result is input into a computer, and then the computer stores the detection result into a cloud server; and S2, the qualified small plates are used for producing a printed circuit board, after an inner layer is etched, size detection, surfacedefect detection and electrical property detection are performed in sequence, the detection result is input into the computer, and then the computer stores the detection result in the cloud server. Bydetecting three stages of etching an inner layer of the product, etching an outer layer of the product and forming the finished board, unqualified products are found in time, remedy cost of a factoryis reduced, product detection is combined with Internet, information sharing is achieved, detection transparency is improved, a production method can be improved and optimized conveniently, and a user can maintain the circuit board conveniently.
Description
technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a method for detecting the production quality of printed circuit boards. Background technique [0002] Printed circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and Assembly errors have improved the automation level and production labor rate. According to the number of layers of circuit boards, they can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer boards. In the past ten years, China's printed circuit boards The board manufacturing industry is developing rapidly, and its total output value and total output both rank first in the world. Due to the rapid development...
