Printed circuit manufacturers want to use good dry film to ensure the quality of printed boards, stable production and improve efficiency. In recent years, with the rapid development of the electronics industry, the precision density of printed boards has been continuously improved. In order to meet the needs of printed board production, new dry film products have been introduced, and the performance and quality have been greatly improved and improved.
PCB light painting process is a very important part of PCB in the circuit transfer process. Any errors that occur in this link may bring serious problems to the subsequent process, so each step inside must be strictly controlled.
As an electronic engineer, designing a circuit is a must-have hard work, and the principle design is perfect. If the board design is unreasonable, the performance will be greatly reduced, and even if it is serious, it will not work properly.
Now that we know that PCBs can provide mechanical support and electrical connections for electronic components, how are these electronic components mounted on the PCB?
To secure the parts to the PCB, we soldered their pins directly to the wiring. On the most basic PCB (single panel), the parts are concentrated on one side and the wires are concentrated on the other side. In this case, we need to make holes in the board so that the pins can pass through the board to the other side, so the parts are soldered to the other side. Because of this, the front and back sides of the PCB are called the Component Side and the Solder Side.
