PCB correction method and correction device

Abstract

The invention discloses a PCB correction method which comprises the steps as follows: a, stacking a plurality of pieces of PCBs into PCB groups, and stacking the PCB groups into a pile, wherein a heat transmission component is placed between every two PCB groups; b, applying pressure to the top of the whole pile of stacked PCB groups and heating for roasting; and c, performing cold pressing on the pile of PCBs. The invention further discloses a PCB correction device which comprises a roaster, and a carrier used for stacking and placing PCBs to be corrected; and the PCB correction device is characterized in that the carrier can be arranged in the roaster in an in-out manner, and is provided with a pressurizing component capable of applying pressure to the whole pile of PCBs simultaneously, and heat transmission components. According to the invention, pressure is applied to the top of the whole pile after the plurality of groups of PCBs to be corrected are stacked into the whole pile, so that the pile of PCBs can be corrected simultaneously, and production efficiency is improved; and compared with the traditional method, the PCB correction method and device for correcting the PCBs, disclosed by the invention, have the advantage that, double-area products can be processed every time.

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 ...

AI Technical Summary

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
