초록 | In practical wet process of PCB manufacturing such as etching, rinsing and developing process, reactive or non-reactive liquid would be sprayed on the PCB panel through nozzles collectively connected to the manifold. As one PCB panel in manufacturing process has the pre-determined number of PCB products(units), the uniformity of these wet processes which is defined as the performance difference within a panel is one of the most important features of wet process. In this paper, the prediction of nozzle trajectory has been performed by the combination of algebraic formula and numerical simulation. With the pre-determined geometrical factors of nozzle distribution, the trajectories of individual nozzles were predicted with the change of process operational conditions such as panel speed, nozzle swing frequency and so on. With the help of this newly developed tool, it is possible to predict the uniformity of etching, developing and rinsing performance. It is expected to be very useful way to improve the wet process at manufacturing any PCB products. |
