Requirements on the minimum length of tape for SMT patch proofing materials: In the production process of SMT patch, materials are mainly packaged by pallets and tape braiding. Such packaging is convenient for taking materials from the SMT patch machine a
Polarity means that the positive and negative electrodes or first pins of a component are in the same direction as the positive and negative electrodes or first pins on the PCB(printed circuit board). If the component does not match the direction on the P
Ways to improve SMT machining efficiency: (1) Aim for fewer component changes, (2) Focus more on PCBA assembly, (3) You should know every step of the SMT process
This paper introduces the inspection requirements of PCBA processed products: 1. Inspection requirements of PCBA processed products; 2. Quality requirements of component mounting process; 3
Shenzhen kingford is a PCBA processing manufacturer with more than 20 years of experience in PCBA processing. We have our own SMT processing plant, which can undertake mass SMT SMT processing services. Next, we will introduce what problems need to be cons
Core and key points of SMT process: The goal of SMT process is to produce qualified solder joints. A good solder joint depends on the right pad design, the right amount of solder paste and the right reflow temperature curve
5 suggestions to solve the problem of component shortage: 1. Expand the breadth and depth of cooperation between component suppliers; 2. Order to be prepared in advance, 3. Manage priority, 4. Reduce component loss, 5. Respect suppliers
Low cost is an important determinant in choosing a manufacturer, but it needs to be remembered that low cost should not come at the expense of quality, so the cost offered by the manufacturer needs to be competitive because the manufacturer has a strong r
Before SMT proofing, PCB should test: 1. PCB light plate deformation, surface smooth; 2. 2. Whether there is oxidation on the circuit board welding plate; 3. Whether the copper coating on the circuit board is exposed; 4. Whether the PCB has been baked for
PCBA circuit board debugging steps and methods: 1. Board surface observation and resistance inspection, 2. Install components, 3. Detect the output voltage of the power supply, 4. Preset overcurrent protection current, 5. Install other modules and power t
Accurate and reliable rework is more difficult in lead-free environments because the PCBA and the component closest to the component to be serviced must withstand multiple high temperature cycles. To protect the stability of the board, the preheating temp
Here are some possible reasons for potential growth: 1. PCB solder resistance details; 2. Surface treatment; 3. Screen printing; 4. Impedance details: 5
