Some basic knowledge of patch components

Now there are more and more patches for welding machine circuit boards because of its high efficiency and low cost. At present, the vast majority of welding machine maintenance personnel on the patch is still very strange. They have already become accustomed to plug-in components and are generally repulsive to patch welders. The headache of the patch is that the component is too small, there is no identification model on the component, the circuit board of the patch is too dense, and the patch component is unfamiliar. These factors have caused the patch welder to need to change the board to get it done, and there are very few people who can skillfully repair the patch circuit board. Welding machine circuit board patch is a major trend, maintenance personnel are faced with the urgent need to upgrade knowledge. Survival of the fittest, those who can't keep up with the pace of upgrading, the road will become narrower and narrower until they are eliminated. Here are some basics about patch components.

Main Failure Causes of Chip Capacitor

There are two main causes of mechanical cracking. The first is an extrusion crack, which is generated during the operation of the component pick-up on the PCB board. The second is the deformation crack caused by the bending or twisting of the PCB board. Extrusion cracks are mainly caused by incorrect pick-and-place machine parameter settings, while bending cracks are mainly caused by excessive bending of the rear plate of the PCB board on which the components are welded.

Solid capacitor all solid state motherboard is what do you mean?

We know that the three major accessories of CPU, memory and graphics card directly determine the performance of the whole machine. Whether the purchased motherboard can provide sufficient and stable power supply environment for these three accessories has become a very important factor. The power supply circuit of CPU is usually composed of three parts: capacitor, inductor coil and field effect transistor (MOSFET). In addition to providing a more pure and stable current for the CPU, it also plays a role in reducing the current limit to ensure the normal operation of the CPU. In the power supply circuit of the main board, the higher the specifications of the capacitor and the inductor coil and the more the number of field effect transistors, the better the quality of the power supply circuit.
