The invention discloses an electroplating method for a circuit board, which comprises: sequentially transporting a plurality of circuit boards into a plating tank in a chain-type continuous forward manner; detecting each circuit board entering the entrance of the plating tank ; When it is detected that the full tank current of the current entering circuit board is different from the full tank current of the previous entering circuit board, start timing, and according to the length of timing, the full tank current of the currently entering circuit board and The full tank current of the circuit board entering the previous one adjusts the working current of the plating tank; the full tank current refers to the working current when the circuit boards accommodated in the plating tank have the same electroplating parameters; according to the adjustment The final working current is used to electroplate the circuit board in the plating tank. Correspondingly, the invention also discloses a circuit board electroplating device. By adopting the embodiment of the present invention, seamless switching of electroplating of different circuit boards can be realized, and the production utilization rate of circuit boards can be improved.

The present invention discloses a type of sea industry for molding device and molding method. This device includes: support blocks, support blocks include support surface one and support surface two, and support surface one and support surface two.Type slot, V -shaped grooves are used to support the part of the workpiece to be processed; the upper anvil, the upper anvil includes a horizontal working face, and the horizontal working surface is used to squeeze the workpiece on the support block of the center line of the V -shaped slot;The upper -type anvil, the upper -type anvil includes the formation surface that matches the outer contour surface of the coastal -to -ring forging. The molding surface is used for horizontal working surface to squeeze and then along the central line of the V -shaped slotextrusion.The present invention has changed the tradition of the tradition of the coastal tolerance to the tradition of the ring forging, avoiding the problem of folding and low imitation of the peeling molding method, and improving the molding efficiency and product utilization of the sea industry for the type of ring forging.

The invention discloses an MOCVD (Metal-organic Chemical Vapor Deposition) system with multiple extensional reaction cavities, and the system provided by the invention is used for carrying out extensional reaction on a plurality of substrates arranged on a tray. The MOCVD system comprises a transmission cavity provided with a mechanical arm, a plurality of transit stations and at least two extensional reaction cavities, wherein the plurality of transit stations are connected with the transmission cavity; the substrates can be simultaneously subjected to extensional reaction in the extensionalreaction cavities; and according to mechanical automation operation, the trays in the extensional reaction cavities can be taken out and put in without opening extensional reaction cavity covers, thereby improving the system capacity, saving the time for cooling the extensional reaction cavities and changing trays, and improving the production use ratio of equipment. Because the plurality of extensional reaction cavities share one set of transmission cavity, mechanical arm and the like, one and several other sets of corresponding equipment are saved, the setup cost and operation cost are lowered, and installing sites of the equipment are saved. Because the transit stations have the function of a pre-processing cavity, the tray can be precooled and preheated according to the production requirement so as to further improve the production efficiency.
