Automated Optical Inspection( AOI ) is a method that uses optics to capture PCB images to see whether components are missing and in the correct position or not to identify defects and ensure the quality of the board manufacturing process. That’s to say, A
Grande is a professional circuit board copying company with a PCB Reverse team with more than 10 years of practical experience in circuit board copying. It can provide circuit board conversion, Schematic reverse, IC model identification, IC decryption, an
As we all know, a good PCB design engineer should master a wide range of knowledge systems, including electrical theory, component performance, digital and analog circuits, PCBA processing technology and DFM manufacturability theory, welding practice oper
With hundreds of industrial IoT devices collecting and sharing data together, factories have become more complex. Combined with software automation, PCBA manufacturers are also using IoT-based networks to optimize their operations, find new efficiencies a
As we all know, MID and VR devices are one of electronic devices. Except for useful work, most of the electrical energy consumed during work is converted into heat and emitted. The heat generated by the electronic equipment causes the internal temperature
The spacing between SMD components is an issue that engineers must pay attention to when designing PCB. Because if the pitch is too small, then it will be quite difficult to print solder paste and avoid solder joints.
The recommended distance is a
The shielding cover actually is an alloy metal cover, which is a vital component to reduce display radiation. It can effectively reduce the mutual interference between modules when used in MID or VR products. As shown in Figure 1, it is common in the main
Different processes, such as reflow soldering and wave soldering, have different component layouts. When double-sided reflow soldering, there are different requirements for the layout of the A side and the B side; Selective wave soldering and traditional
Regarding the similarities and differences of the coating materials for land, sea and air equipment, plenty of literature can be searched online. In short, I believe that moisture resistance is the most basic performance requirement of various three-proof
1. The wetting of PCBA pad and component welding surface does not meet the processing requirements;
2. The use of solder paste does not meet the processing standards;
3. The thermal expansion coefficients of welding and various electric materials are no
