Many friends say that the selection of SMT processing plantto see the equipment is the most important, why there is this statement, where is the basis of it, the next SMT processing plant in Shenzhen -kingford for everyone to analyze.
1. Advanced equipment is the prEMIse of implementing precision technology
Honglijie, as a company engaged in high-end PCBA product customization, such as MedICal electronics and vehicle electronics. High-end products are not just a noun. Strictly speaking, it is a verb. It is a product that needs to be coordinated through a complex set of processes. It is the crystallization of high technology. For example, the current mainstream 7nm chip, if we use a machine 10 years ago to install, we cannot guarantee that the installation will not be successful, at least we can guarantee that the yield will not reach 10%. Therefore, for high-precision products such as automobiles and healthcare, welding quality is not only a strength, but also a responsibility to life. If we do not have advanced equipment, no matter how detaiLED and clear the SMT process instructions are, they are just words on paper.
2. Advanced equipment is the guarantee of MARKet competitiveness
Any SMT patch manufacturer has its own unique advantages. But the core competitiveness must be able to adapt to the market, to provide customers with quality products and services. No superficial work in electronics manufacturing can make a product go smoothly. Under the premise of successful matching of engineering team and engineering process capability, advanced equipment becomes the icing on the cake, but also the guarantee of the factory to maintain market competitiveness.
3. Advanced equipment is the foundation of customer service
The core of the real economy is the ability to create tangible products through deep processing of raw materials and socialized labor. It involves all aspects of the state, society and the individual. Therefore, as a part of China's physical manufacturing industry, it is our social responsibility and existence significance to serve our physical customers well. Therefore, to provide service for customers is to realize the delivery from drawings to finished products for customers, so PCBA processing is a bridge between us and customers. Advanced production equipment is the basis of our service to customers.
2. Procedure and method of PCBA circuit board debugging
After PCBA processing is completed, it is necessary to debug the circuit board to verify whether the product function is normal. Then how to start PCBA circuit board debugging? Next, Shenzhen PCBA processing manufacturer - Shenzhen kingford to share the PCBA circuit board debugging steps and methods.
PCBA circuit board debugging steps and methods
1. board surface observation and resistance check
First of all, we should observe whether there are problems on the board, such as cracks, short circuit, open circuit, etc., if necessary, check whether the resistance between the power supply and the ground wire is large enough.
2. Install components
Individual modules, when you are not sure if they are working properly, it is best not to install them all, but one by one, so that you can easily determine the scope of PCB failure.
3. Check the output voltage of the power supply
Generally speaking, you can install the power supply first, and then turn it on to check that the output voltage of the power supply is normal. When supplying power, consider using an adjustable voltage regulator with current limiting.
4. Preset overcurrent protection current
First, the overcurrent protection current is preset, then the voltage value of the regulated power supply is slowly increased, and the input current, input voltage and output voltage are monitored. If there is no overcurrent protection during the upward adjustment and the output voltage is normal, the power supply is normal.
5. Install other modules and power on them for test
Install other modules gradually and power up and test each module installation to avoid overcurrent and component burn due to design errors or component installation errors.
1. Strength assurance
▪ SMT workshop: We have imported SMT machines and a variety of optical testing equipment, capable of producing 4 million pieces per day. Every process is equipped with QC personnel who can keep a close eye on product quality.
▪ DIP production line: There are two wave welding machines. Among them, there are more than ten old employees who have worked for more than three years. Skilled workers can weld all kinds of insert materials.
2. Quality assurance, high cost-effective
▪ High-end equipment can mount precision heterosexual parts, BGA, QFN, 0201 materials. Proofing can be machine paste, also can be hand pendulum.
▪ Samples and large and SMAll batches can be produced. Proofing starting price 800 yuan, batch starting price 0.008 yuan/point, no start-up fee.
3. Rich experience in SMT and welding of electronic products, stable delivery time
▪ Has served thousands of home appliance subsidiaries, involving various kinds of automotive equipment and industrial control motherboard SMT SMT processing services. Products are often exported to Europe and the United States, the quality of new and old customers affirmed.
▪ On time delivery, usually within 3-5 days after the board is assembled, small batch expedited can also be shipped on the same day.
4. Strong maintenance ability and perfect after-sales service
▪ Experienced maintenance engineers are able to repair defective products caused by various welding problems and ensure the connectivity rate of each circuit board.
▪ 24-hour customer service staff will be ready to respond and resolve your order as soon as possible.
