The reason why the CPK statistical results of SMT automatic solder paste printer can reflect the printing accuracy of its equipment comes from the calibration principle of machine camera. Therefore, before analyzing the CPK statistical principle, first introduce the principle of machine camera calibration, and then analyze the CPK statistical process of machine in combination with the principle of calibration.

SMT electronic patch processing factory needs more than 100000 to buy and evaluate a full-automatic solder paste printer, and now there are more and more domestic manufacturers of full-automatic solder paste printers. Most manufacturers buy a full-automatic solder paste printer by themselves, and then dig out several people from the original manufacturer of the old full-automatic solder paste printer to produce it. A lot of technicians know a little about it, and then assemble it and sell it, regardless of its quality. Anyway, they sell it cheaply. After making money, the company cancelled as soon as it sold. You can't find anyone. This has become a great trouble for the customers of electronic enterprises. Sometimes when the machine breaks down, it can't be repaired, and more than 100000 people are in the water. Therefore, if you buy automatic solder paste printing machines and other production equipment, you should find large and influential manufacturers to buy them, which will also guarantee future services. Let's introduce several aspects that need to be paid attention to when buying a full-automatic solder paste printer.

How to evaluate the CPK performance of full-automatic solder paste printer, and matters needing attention in CPK statistics and adjustment analysis of printing accuracy of full-automatic solder paste printer

When purchasing a full-automatic solder paste printer, the following aspects should be considered:

1、 Image recognition mode, such as image recognition of positioning system;

2、 PCB size is applicable to a wide range, including the thickness of PCB of course;

3、 Whether there is a self diagnosis system, which is convenient for users to conduct simple troubleshooting;

4、 Whether the printing machine has nitrogen interface and the tightness of the machine;

5、 Whether the structure of the machine is convenient for the maintenance of the equipment;

6、 Overall stability of machine structure, such as integrated workbench;

7、 The cleaning of formwork is various and optional;

8、 The application of mark recognition vision system can automatically search;

9、 Easy to use interactive operation;

10、 Whether the appearance of the printing machine is beautiful, whether it matches the whole line properly, and whether the appearance color is optional;

11、 Whether the power and gas conditions of the printing machine are harsh;

12、 The cost performance of the machine.

13、 The length of the whole printing cycle and the production capacity of the machine;

14、 Check the consistency of repeated printing times. Under the condition of good printing consistency, the more printing times, the higher the repetition accuracy of the machine;

15、 Whether the internal electrical appliances and structural parts of the printing machine are assembled in disorder;

16、 The length of the warranty period of the main parts of the printing machine;

17、 Whether the merchant provides vulnerable / consumable parts with reasonable price;

Strong capital driven technological innovation

Science and technology are the primary productive forces, and technological innovation is a greater driving force for the progress of the industry and even society. Technological innovation requires continuous R & D capital investment. For small and medium-sized enterprises with capital shortage and financing difficulties, they are often tired of coping with the increasingly fierce market competition, and it is difficult to have excess capital invested in technological R & D, so they can only defend but not attack in the competition, It is difficult to form core competitiveness. However, for large enterprises with strong strength, they are rich in resources and capital. As long as the business philosophy and direction are correct and pay attention to R & D, they can realize the development of technological innovation industry and form their own core competitiveness.
