Example Embodiment

[0032] Example 1

[0033] like figure 2 and image 3 The shown device for correcting a PCB board includes an oven 210 and a carrier 220 that can enter and exit the oven. The bottom of the carrier 220 is provided with a roller 221, and the bottom of the oven 210 is provided with a guide rail 211 matching the roller.

[0034] The above-mentioned carrier 220 is also provided with a pressurizing component. In this embodiment, the above-mentioned pressing component includes a pressing steel plate 230 .

[0035] In addition, there are heat transfer components under the pressurized steel plate, including 4 heat transfer steel plates 231 that can be arranged at intervals between the stacked PCB boards. The thickness of the heat transfer steel plates is 1mm, and the surface of the heat transfer steel plates is plated with 0.05mm aluminum Thermal conductive layer.

[0036] The method of using the above device to correct the PCB board is as follows:

[0037] a. Stack the PCB board...

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 ...
