A purpose of the present invention is to provide a conductive paste which is capable to prevent the structural defect and to provide a method for producing electronic components including an internal electrode layer formed by the conductive paste. A conductive paste comprises metallic particles, solvent, rein, a first inhibitor, a second inhibitor and a third inhibitor, wherein sintering start temperatures of the first inhibitor, the second inhibitor and the third inhibitor are higher than a sintering start temperature of the metallic particles, when an average particle size of the first inhibitor is defined as "a", an average particle size of the second inhibitor is defined as "b", an average particle size of the third inhibitor is defined as "c", "a", "b" and "c" fulfill a predetermined relation.

The stack frame of multiple chips includes carrier for chips, first chipset, cushion piece, and second chipset. The first chipset possesses multiple chips. Possessing unilateral weld pads, these chips are stacked on carrier for chips in stair shape. The cushion piece is joined to the first chipset. Possessing unilateral weld pads, the first chipset possesses multiple chips. Bottommost chip in the second chipset is joined to the cushion piece in deflection towards direction of weld pads of the first chipset. Then, the second chipset is stacked on carrier in stair shape. Weld pads are revealable in order to prevent stack of chips from exceeding packaging region. The invention encapsulates chips in multiple layers to package without increasing area of package. Being able to be stacked in package, multiple chips does not deviate stack in single direction so as to facilitate throwing for weld part of chip.

The invention provides a sectional material conveying bracket which comprises a bracket body. A fixing block is arranged at one end of the bracket body, a plurality of installation blocks are arranged at the other end of the bracket body, and a hook for hoisting is further arranged above the end, where the fixing block is arranged, of the bracket body. Sectional materials are fixed to the bracket body with ropes and prevented from sliding off and causing accidents, work efficiency is improved, and conveying safety is increased.

The invention discloses a six-wavelength on-site physical evidence laser detector. The physical evidence laser detector is characterized in that the laser detector comprises two laser generation systems and a single laser output channel; in the two laser generation systems, one laser generation system comprises a first laser emission module, a first wavelength generation optical path, a second wavelength generation optical path and a third wavelength generation optical path, and the first wavelength generation optical path, the second wavelength generation optical path and the third wavelength generation optical path are arranged at the output side of the first laser emission module; the other laser generation system comprises a second laser emission module, a fourth wavelength generation optical path, a fifth wavelength generation optical path and a sixth wavelength generation optical path, and the fourth wavelength generation optical path, the fifth wavelength generation optical path and the sixth wavelength generation optical path are arranged at the output side of the second laser emission module. lasers outputted from the six wavelength generation optical paths are collected to a single laser output channel through a plurality of reflectors for output. Six-wavelength integration of main wave bands covering physical evidence detection is achieved, requirements of searchlighting with different traces and different wavelengths during the scene investigation process in the criminal science and technology are met furthest, and the provided laser detector has advantages of compact structure, stable performances, convenient operation, high conversion efficiency and the like.
