The invention relates to a protruding point luminescent diode, wherein a protruding point lower metal is plated on an electrode of a protruding point luminescent diode chip, metallic protruding points are grown on the upper portion of the protruding point lower metal, a passivation layer is grown on the surface of the upper portion of the luminescent diode chip excepting the surface of an electrode, a welding pad is made on a packing support, the metallic protruding points of the protruding point luminescent diode are inversely welded on the welding pad of the packing support. The method for preparing the diode comprises the following steps: making the passivation layer, sputtering a metal sacrificial layer, making a photoresist mask, forming the metallic protruding points, removing the photoresist mask, removing the metal sacrificial layer, reducing, cutting into separated chips and inversely welding on an SMD support, and then forming an inversely welded LED die set. The method enables the chip of the luminescent diode to be without the gold wire bonding and the die bond technique, directly switches a circuit and assembles the chip on a base plate or a metallic support, realizes the miniaturized package and the die set with multiple chips, and successfully solves the problem of the heat dissipation of the luminescent diode.

Lithium ion battery assembly method and lithium ion battery

The invention belongs to the technical field of lithium ion batteries, and particularly relates to a lithium ion battery assembly method which comprises the following steps: baking a positive plate, anegative plate and a diaphragm to obtain a baked positive plate, a baked negative plate and a baked diaphragm; laminating and / or winding the baked positive plate, the baked negative plate and the baked diaphragm; welding a tab to obtain a bare battery cell; soaking the bare battery cell in an electrolyte to obtain a battery cell soaked in the electrolyte; putting the battery cell soaked in the electrolyte into a shell, and performing packaging; and forming and re-packaging the packaged battery cell to obtain the lithium ion battery. According to the method, the bare battery cell is directly soaked in the electrolyte, so that the battery pole piece and the diaphragm are fully soaked by the electrolyte; then the liquid supplementing procedure is added according to the designed weight, so that the electrical consistency among battery batches can be ensured; and the standing time of a battery after liquid injection can be shortened, and the production efficiency is improved. The lithium ion battery prepared by the method disclosed by the invention is high in safety performance and good in cycle performance.

Manufacturing method for integral LED light source module

The invention relates to a manufacturing method for an integral LED light source module. The manufacturing method comprises the following technological steps that: a metal substrate is precut; an LED support is manufactured on the metal substrate through plastic encapsulation; chips are placed in the LED support one by one through adhesive dispensing and die bonding, and the electrodes of the chips are connected with the electrode pin of the LED support through pressure welding and routing; adhesive is injected to encapsulate and protect the LED chips and the routing; precut connecting parts on the two sides of the LED support are punched to be cut to form an integral LED light source assembly; an integral test is conducted to all LED light emitting elements; and finally punching discretion is conducted to obtain the required integral LED light source module according to the required series and parallel circuits and the number of the LED light emitting elements. The invention properly uses the metal substrate as the base material, uses high-reflectivity plastics to be combined with the metal substrate for series and parallel circuit connection to manufacturing the integral LED light source module, omits the manufacturing process of pin bending and semi-discretion and the tape armoring and the manufacturing process of the existing SMT on the basis of the existing SMD manufacturing process, and greatly shortens the manufacturing process of the elements.
