The present invention provides a method for manufacturing a printed circuit board and a print circuit board manufactured thereby, in which through holes of a core board are filled by reverse pulse plating so that it allows to manufacture a core board having greater than 100 μm of a thickness which has been a processing limitation with conventional technologies and form bumps on a thick insulation layer, which has been difficult till now, and thus providing resistance against pressure of paste bumps produced during stacking due to the increased strength of a core board, convenience to join between layers, excellent heat-releasing effect, and collectively stacking of core boards, which was not possible with conventional methods.

The core member constitutes a core substrate of a circuit board. The core member comprises: a carbon fiber-reinforced core section, in which prepregs including carbon fibers are thermocompression-bonded; and copper foils being respectively thermocompression-bonded on the both side faces of the carbon fiber-reinforced core section with prepregs including glass fibers. The pregregs including glass fibers are composed of resin, whose melting temperature range is higher than that of resin composing the pregregs including carbon fibers.

A ceramic core used for fabricating a hollow turbine blade for a turbine engine using the lost wax casting technique, the blade including calibrated dust-removal holes emanating from a top of at least one cavity and opening out into a bathtub of the blade, wherein each of the calibrated dust-removal holes is formed in a core portion of height that is determined to be sufficient to guarantee mechanical strength, the core portion including a through orifice of axis perpendicular to a longitudinal axis of the calibrated dust-removal hole and defining on either side of the through orifice firstly a core cylinder having a determined diameter corresponding to the dust-removal hole that is to be formed, and secondly a remaining core volume that is to be plugged after casting, such that the calibrated dust-removal hole is obtained without drilling and without using connection rods.

A method for densification of the surface layer of an optionally sintered powder metal component comprising the steps of decarburizing the surface layer for softening the surface layer of the component, and densifying the surface layer of the component.

The invention discloses a balance beam core stable strength training and monitoring device based on a projector, and relates to a balance training device. The device solves the problems that an existing balance beam is single in training means, and lacks the balance beam core stable strength training and monitoring means combined with a projection system. The balance beam core stable strength training and monitoring device based on the projector conducts image transmission on a surrounding projection screen through the projector to enable a trainer to conduct training under the visual impact environment, so that the aim of intercoordination whole between the visual sense and the body is achieved. The device can reflect the balance state of the trainer in real time and enable the trainer to know the balance state of himself in real time, and therefore the trainer can adjust the training state of himself initiatively. The device has the communication function and can transmit the detected balance state in the training process to other devices. The balance beam core stable strength training and monitoring device based on the projector is suitable for the fields such as physical education, medical treatment, aviation and navigation.
