A multi-layer circuit board, as the name suggests, can only be called a multi-layer circuit board if it has two or more layers, such as four layers, six layers, eight layers, and so on. Of course, some designs have three or five layers of circuitry, also known as multi-layer PCB circuit boards.

With the increasing demand for PCB circuit boards in the market, many PCB manufacturers will reduce material costs to obtain higher profits. However, the quality of the PCB boards produced in this way will definitely not be qualified. So how to distinguish the quality of PCB circuit boards among many manufacturers?

During SMT production of circuit boards, poor soldering may occur, which is generally related to the cleanliness of the PCB bare surface. If there is no dirt, there is basically no poor soldering. Secondly, poor soldering flux and temperature during soldering. So, what are the specific manifestations of common tin defe……

When making a PCB circuit board, a detailed description of the PCB surface treatment process is attached. The choice of PCB surface treatment process has a direct impact on the product quotation. Of course, different process treatments have their advantages and disadvantages, and the most important thing is to see wher……
