Latest Patents

Isaji's latest patents include a laser processing method and equipment specifically designed for printed circuit boards. This innovative method involves using a laser to process a circuit board that consists of at least two layers: a conductive layer with multiple holes and an insulating layer. The conductive layer is positioned on the surface of the insulating layer, which is processed by applying a laser beam to areas of the insulating layer that correspond to the holes in the conductive layer. The circuit board is irradiated with the laser beam, and a reflected laser beam is detected. If the detected value of the reflected laser beam deviates from a desired value, the laser processing of the insulating layer corresponding to an abnormal hole in the conductive layer is halted. Conversely, if the detected value aligns with the desired value, the insulating layer corresponding to the hole is processed.

Another notable patent is a laser machining method and apparatus that facilitates drilling holes while ensuring secure conduction between adjacent conductive layers. This invention allows for adequate detection of the machining state of a workpiece and effective control of the machining process. The method involves presetting the number of laser pulse outputs necessary for secure machining. During the laser machining process, both the reflected laser beam intensity from the workpiece and the incident laser beam intensity are monitored. The machining state is assessed, and if the workpiece reaches the desired state before the set number of laser pulse outputs is achieved, the machining is completed. If not, the process continues until the preset number is reached. This innovation results in high-quality hole drilling with improved yield and reduced machining cycle time.
