Problems solved by technology
The structure of the above-mentioned device is complicated, and the utilization rate of the equipment is low. Only 2-3 stacks of PCB boards can be corrected each time. Since the hot pressing and cold pressing steps are all carried out in the oven, the processing takes a long time and the efficiency is very low.
When using the above-mentioned device to correct the PCB board, in order to carry out the follow-up process, the PCB board needs to be moved many times, and the operation is inconvenient and it is easy to scratch the PCB board, resulting in scrapped products

Abstract
The invention discloses a method for rectifying a PCB board, which comprises the following steps: a. stacking several PCB boards into a PCB group, and stacking several PCB board groups into a stack, and placing a transmission line between each stack of PCB boards. Hot components; b. Apply pressure and heat to the top of the stack of PCB boards; c. Cold press the stack of PCB boards. The invention also discloses a PCB straightening device, which includes an oven and a carrier for stacking PCB boards to be straightened. A pressurizing component capable of simultaneously applying pressure to a whole stack of PCB boards; the carrier is also provided with a heat transfer component. In the present invention, several stacks of PCB boards to be corrected are stacked into a whole stack and then pressure is applied on the top of the whole stack, thereby correcting the stack of PCB boards at the same time and improving production efficiency. The PCB board correction method and device disclosed in the present invention are used to correct PCBs Board, each time can process twice the area of products compared with traditional methods.
Description
technical field [0001] The invention relates to the technical field of PCB board correction, in particular to a PCB board correction method and a correction device. Background technique [0002] When making a PCB (Printed Circuit Board, printed circuit board), if the finished PCB has board bending, board warping, etc., it is generally corrected directly by pressing and baking during the testing and visual inspection process. see figure 1 , the traditional straightening device is set in the plate bending and straightening machine 100, which includes an oven 101, an upper table 102 and a lower table 103, the upper table 102 can slide up and down in the oven 101, and the lower table 103 is fixed in the oven 101 in. When using the correcting device, first stack several bad PCB boards into a stack and place them on the lower table 103, then move the upper table 102 downwards and directly press it on the PCB on the lower table 103 and keep it for a period of time. The flatness ...
