Self-layer-thickness-adaptive slicing method and printing system

The invention provides a self-layer-thickness-adaptive slicing method and a printing system. The self-layer-thickness-adaptive slicing method comprises the steps that a 3D model of a to-be-printed object is acquired; the 3D model is dispersed into d1, d2 to dn layers of models with an identical layer thickness; the midperpendicular of the 3D model is acquired; the 3D model is divided with the sameangle by taking the midperpendicular as the center, so that a plurality of vertical slices are obtained; the vertical slices are dispersed into a plurality of layers with the same layer thickness h,so that a plurality of comparison points on the outlines of the vertical slices are acquired; every two adjacent comparison points on each vertical slice are connected to form a slash, and an includedangle a between each slash and the horizontal direction is calculated; and the angles a are compared with a threshold S, and whether two adjacent layers are combined for slicing or not is determined.By adopting the self-layer-thickness-adaptive slicing method, self-adaptive slicing is performed on the 3D model of the to-be-printed object with different layer thicknesses; and the printing systemis provided for directly printing the self-layer-thickness-adaptive layer models; and printing speed is accelerated on the premise of not affecting printing precision and printing object quality.

Fluvial facies sand body discontinuous boundary fine characterization seismic interpretation method

The invention relates to a fluvial facies sand body discontinuous boundary fine characterization seismic interpretation method. The method comprises the following steps: 1) according to fluvial facies sand body positive rhythmic deposition characteristics, in combination with demands on property extraction time window by subsequent property analysis, a sand body enveloping method is adopted to interpret construction of a sand body unit; 2) an ant tracking property and a curvature property are extracted on a target reservoir section; 3) the interpreted sand body is used for enveloping an extracted amplitude plane property, a curvature plane property and an ant tracking plane property with top bottom as time window; 4) a curvature plane property and an ant tracking plane property of a seismic profile are taken for comparison and analysis, and thus a sand body discontinuous boundary is judged; 5) vertical slice interpretation is carried out on the amplitude property, the discontinuous boundary caused by vertical overlapping of sand bodies are judged auxiliarily and a sand body deposition period is divided; 6) according to the discontinuous boundary plane judgment result acquired in the fourth step and the vertical sand body period dividing conclusion acquired in the fifth step, building of sedimentary facies recognition is assisted.

ICD (Internal Connection Defect) detection method for PCB

The invention discloses an ICD detection method for a PCB. The method comprises the flowing steps that a vertical slice of a PCB sample is made, and a metallographic microscope is used to observe whether there is a crack between an electro-coppering layer and an internal copper ring in the vertical slice; if there is, an outside force is used to separate the whole electro-coppering layer from the internal copper ring, an unthreaded hole is formed in the PCB; if there is not, it is shown that no residual glue exists between the electro-coppering layer and the internal copper ring, and no detection is needed any longer; and a scanning electron microscope is used to detect the internal copper ring to observe whether residual glue exists on the internal copper ring. Vertical slicing and copper wire pulling are carried out on the circuit board sample, the electro-coppering layer is directly separated from the internal copper ring, and the scanning electron microscope is used to directly observe whether residual glue exists on the electro-coppering layer; and thus, the detection method can be used to detect whether cracks and residual glue exist between the electro-coppering layer and the internal copper ring is a more direct, effectively and accurate manner, and the ICD detection efficiency of the PCB is greatly improved.

Delamination failure detection method of printed circuit board

The invention relates to a printed circuit board layering failure detection method, which comprises the following steps that a layering fracture printed circuit board is subjected to vertical slicing so as to judge whether the layering position is between a glass fiber layer and a resin layer or between a core plate and the resin layer or between a browning layer and the resin layer; if the layering position is between the glass fiber layer and the resin layer, the layering failure reason is judged according to the water absorption rate before and after the board baking treatment of the printed circuit board; if the layering position is between the core plate and the resin layer, the layering failure reason is judged according to the element ingredients and the microstructure image of the core plate and the resin layer; if the layering position is between the browning layer and the resin layer, the layering failure reason is judged according to the element ingredients and the microstructure image of the browning layer and the resin layer. The method provided by the invention can be used for detecting the layering reason by aiming at different layering positions of the printed circuit board, so that the subsequent pasting process can be improved.
