PCB board empty iron refers to the formation of an extremely tiny through-hole on the surface of the PCB board through a special processing technology and laying a layer of metal or alloy on the surface of the through-hole. This processing method is widely used in mobile devices, automation equipment, communication equipment and medical equipment.
In PCB board empty iron, the two adjacent through-holes must maintain a certain distance between the two holes, which is the difference between it and ordinary through-holes. Empty iron through-hole processing is more difficult, requires high-precision processing equipment and fine control of the process, but also to consider the choice of materials and process safety.
The emergence of the PCB board empty iron for the development of electronic equipment precision and miniaturization provides a technical guarantee, so that the circuit board line compression is more tightly packed, the weight of the product is also lighter, while the existence of empty iron through-hole can also play the effect of the cooler. Therefore, the application of empty iron through-hole will become more and more widely used, and become a modern electronic manufacturing industry is highly favored by a technology.
