Commercial applications of digital printing technologies on PCBs

摘要

The PCB industry is quickly gearing up for the digital printing age. While photo imaging and screen-printing have been commonly used as recognized and established techniques in the PCB industry, their high tooling costs and time-consuming procedures are willingly exchanged by digital printing, following the establishment of this technology both in everyday office uses and in a variety of industrial applications. In the PCB industry, a number of companies emerged lately to offer various digital printing system configurations. The article discusses basic requirements from PCB inkjet printing systems. Possible solutions and basic system engineering considerations are presented, in order to show the optimal system configuration.
