PCB ink is generally divided into three types: PCB etching ink, solder mask ink and text ink. Others are conductive carbon oil (also known as conductive carbon ink) and conductive silver oil (also known as conductive silver paste). The latter two generally use less.

Blistering on the board surface of the circuit board is actually a problem of poor adhesion of the board surface. Further extension is the surface quality of the board surface, which includes two aspects:

PCB is almost the same on the surface regardless of its internal quality. It is through the surface that we see the differences, which are crucial to the durability and function of PCB in the whole life. Whether in the manufacturing and assembly process or in practical use, PCB should have reliable performance, which is very important. In addition to relevant costs, defects in the assembly process may be brought into the final product by PCB, and faults may occur in the actual use process, resulting in claims. Therefore, from this point of view, it is not too much to say that the cost of a high-quality PCB is negligible. In all market segments, especially those producing products in key application areas, the consequences of such failures are unimaginable. These aspects should be kept in mind when comparing PCB prices. Although the initial cost of reliable, guaranteed and long-life products…
