Innerlayer panels are provided with high density fiducials during manufacture. The fiducials can be identified using X-rays without etching away portions of the innerlayer panel to expose the fiducials.
Abstract:
A display module includes a display panel having a substrate as a base at least provided with conductive circuits and external connection pins; and a circuit board electrically connected with the external connection pins of the substrate through a conductive material for driving the display panel. The substrate could be electrically connected with the circuit board without the need of flexible printed circuit boards, thereby simplifying structure of the display module.
Abstract:
A first set of fiducials is formed in fiducial locations on a workpiece such as a ceramic greensheet; a pattern is formed in the workpiece; a best fit set of fiducials is formed by a least squares technique based on the pattern; and a second set of fiducials is formed over the fiducial locations of the best fit set.
Abstract:
A manufacturing method for wiring substrates for photographing a positioning mark formed with a high precision using reflected light and executing a relative positioning operation between a wiring substrate workpiece and an exposure mask based thereon. The method steps include successively laminating a conductor layer and dielectric layer on a plate-like core and forming a positioning mark by irradiating the main surface of dielectric layer with laser light. By irradiating the positioning mark with position detecting light from the side of the main surface of the dielectric layer and detecting reflected light, relative positioning between the wiring substrate workpiece and the exposure mask is based on the detection result.
Abstract:
A method of creating a mathematical model which is employed in the determination of at least one work location in a multi-layered laminated circuit panel. The mathematical model for modifying drill data takes into consideration translational and rotational compensations caused by the encountered stretching or shrinking of the multi-layered panel subsequent to pressing or due to thermally processing, whereby the mathematical model may be utilized to modify drill data in order to accurately predict hole or via locations.
Abstract:
In the high-frequency module of the present invention, an insulating resin is formed so as to seal a high-frequency semiconductor element mounted on a surface of a substrate and further to seal electronic components. Furthermore, a metal thin film is formed on the surface of the insulating resin. This metal thin film provides an electromagnetic wave shielding effect.
