Why JX350 40123242 cpu board have error code E101000？ When JX350 40123242 cpu board have error code E101000, what are the possible reasons? 1. Check hardware connections: Make sure that all connections to the CPU board are correct and that there are no loose or damaged cables. In practice, when the CPU board has loose cables, the machine's computer will show that the CPU board is not responding. the CPU board's light will not turn on.   2. Check power and voltage: Make sure the CPU board is receiving the correct power and voltage and is not out of or below the specified range. When the UPS power supply of the JX350 machine is bad, or the voltage is unstable, the machine system will restart automatically. 3. Update software or firmware: If possible, check to see if there are available software or firmware updates that may contain bug fixes. If there is no problem with the machine's power supply, there may be a problem with the hard disk system on the CPU board and a new system will need to be re-downloaded. Our JUKI engineer who specializes in JX350 machine think this maybe the most probable solution. 4. Check other components: Sometimes the error code may not be caused by the CPU board itself, but by other components or system parts connected to it. Check that all related components and system parts are working properly. This code can also appear in the board box when the board next to the CPU card is unstable. The CPU card and the card next to it need to be re-plugged to troubleshoot the problem. 5. Replace the hardware: If all else fails and you suspect a problem with the CPU board itself, then you may need to consider replacing it. Please note that solving a hardware or system failure may require specific skills and experience. If you are unsure how to proceed, or are concerned about possible damage to the unit, it is best to seek professional help, such as contact our company ZK Electronic Technology Co.,Limited, we have a team of 6~10 engineers specializing in the repair and maintenance of various brands of SMT machines, especially specializing in JUKI 2000, FX, RS, and JX100, JX300, JX350 LED machines.

The relationship between the Japanese yen slump and SMT PARTS Recently, the Japanese yen has dropped significantly, and many people have been buying Japanese products like crazy. In the SMT industry, it is also more favorable to buy Japanese original Panasonic, FUJI, Yamaha, JUKI and other brands of feeders, nozzles, SMT mounter parts and other products. Due to the depreciation of the yen, the price of these products will be relatively lower when purchased in US dollars or Chinese yuan. If you are in need of these products in the near future, you are welcome to inquire with ZK Electronic Technology Co. Ltd. by sending an e-mail to the following e-mail address: Connie: fhysmt@hysmt.cn Becky: becky@hysmt.cn Of course, there are several other factors to consider when purchasing these products besides the exchange rate factor: Transportation and Duty Costs: Importing products from Japan may involve transportation and duty costs, which may increase the overall purchase price. However, if you buy directly from China with ZK Electronic Technology, we have cooperated with freight forwarders for many years, we will provide you with the best DHL, FedEx, UPS and special line double clear tax shipping quotes. Product quality and after-sales service: Ensure that the products you buy are genuine, ZK Electronic Technology has been insisting on quality reporting for more than 10 years, and has a team of engineers to provide relevant after-sales service policies to ensure that our customers can get timely technical support and maintenance services in the process of use.

Six Sigma Definition Six Sigma a.k.a.: 6σ, 6Sigma, 6Σ Sigma (Σ, σ)[1][2] is a Greek letter that is a statistical unit used to measure the standard error in a total number. Its meaning is derived to mean that the defect rate of an average company is about 3 to 4 sigma, which, in terms of 4 sigma, is equivalent to 6,210 errors per million opportunities. If a company continually pursues quality improvement to the extent that it reaches 6 sigma, its performance will be close** to meeting customer requirements, with only 3.4 defective items found out of a million opportunities. The Six Sigma (6σ) concept, as a quality management concept, was first proposed by Bill of Motorola in 1986, with the aim of designing a goal: to reduce the number of defects in products and processes in the production process, to prevent product variation, and to improve quality. Really popular and developed, is the practice of General Electric Company, that is, the 1990s developed 6 σ (sigma) management is summarized in the successful experience of quality management, distilled the essence of which the process management skills and * proven methods, to become a kind of management model to improve corporate performance and competitiveness. The management method in Motorola, General Electric, Dell, Hewlett-Packard, Siemens, Sony, Toshiba and many other multinational enterprises has proved to be fruitful. For this reason, some domestic departments and organizations vigorously push 6σ management in domestic enterprises and guide them to carry out 6σ management. With the accumulation of practical experience, it has been derived from a mere process optimization concept to a management philosophy. It is not only a standard to measure the capability of business processes, not only a set of methods for continuous optimization of business processes. The Greek letter σ (pronounced SIGMA, capitalized as Σ) is a unit in statistics that represents the standard deviation from the mean. The Six Sigma (SIXSIGMA) quality level indicates that there are only 3.4 defects in a million opportunities for defects in a production or service process, i.e. a pass rate of 99.9997% is achieved. The implementation of Six Sigma quality plan requires management intervention, and by specially trained internal Six Sigma quality plan staff and project leaders to organize and implement, in order to achieve the short-term goal of reducing deviations and improving process capability and the long-term goal of achieving the world** level of Six Sigma. Six Sigma is the enterprise to refine the scientific management of a quality goal, this quality goal is the enterprise within the various departments to work together to be able to achieve the overall. Motorola and General Electric and other companies to implement the achievements of Six Sigma, but also within the business sector hundreds of thousands of impact on product design, production, service, one by one to improve the results of efforts. The Six Sigma approach has affected dozens of management processes and transaction flows. For example, in customer support and product delivery, a better understanding of customer needs and improvements in evaluation systems have enabled us to take greater strides in pursuing service improvements and timely product delivery.
