3. For thick copper PCB, the requirement of hole copper is very strict. The standard of hole copper of PCBONLINE is IPC-600G Level 3 standard, that is, hole copper is equal or greater than 25um. Some customers also require hole copper to be equal or greater than 70um, we can also do that.
4. For more thick copper PCB manufacturers, solder mask processing is the most difficult, if the use of traditional manufacturing technology can not solve the problem of ink inhomogeneity, wrinkle, bubble, line Angle oil. Our factory uses electrostatic spraying equipment , so there will be no such problem in the process of soldering. The working principle of the equipment is to spray soldering ink on the board in a dust-free vacuum environment. The schematic diagram is as follows:
