Description

Technical Field

[0001] The invention relates to the technical field of PCB manufacturing, and in particular to a method and device for manufacturing a PTFE material PCB. Background Art

[0002] With the rapid development of autonomous driving, smart cities, active phased array radars and other fields, the performance requirements for printed circuit boards (PCBs) are increasing. PTFE materials themselves have excellent high and low temperature resistance and aging resistance, low dielectric constant, and low loss characteristics, so the application of PTFE materials in printed circuit boards has been rapidly improved, which has promoted the industry's continuous innovation in material research and development, manufacturing processes, quality inspection and other aspects.

[0003] However, existing printed circuit boards will produce burrs during processing, and traditional drills will damage the hole walls, thus affecting the product. In addition, manual burr removal is inefficient, resulting in slower production.

[0004] In order to solve the above-mentioned defects, in the prior art, a Chinese patent with publication number CN217454192U discloses a PCB drilling and deburring stacking device, which is provided with a lateral shift rod, a slider and a longitudinal slide groove connected to the PCB clamping jaws, and the lateral shift rod is movably connected to the slider, and the slider is slidably connected to the longitudinal slide groove so that the clamping jaw can clamp the PCB to be processed, so that the clamping jaw of the device can clamp the PCB and perform integrated punching and deburring on the PCB, thereby improving the production efficiency of punching and deburring, and the clamping jaw can be moved longitudinally. The slide groove and the lateral shift rod can realize movement in both lateral and longitudinal directions, so as to locate the holes for punching and deburring, thereby improving work efficiency. The punching mechanism is arranged in the device, and the upper pressing plate and the lower pressing plate are arranged vertically up and down by the pressing mechanism. A plurality of connecting rods are arranged between the upper pressing plate and the lower pressing plate. The connecting rods pass through the upper pressing plate and are slidably connected to the upper pressing plate. The connecting rods are fixedly connected to the lower pressing plate. Therefore, when punching the PCB, the lower pressing plate presses the PCB to prevent it from warping and moving during punching, thereby improving the production quality and efficiency of the device.

[0005] In the prior art, a Chinese patent with publication number CN217750746U discloses an automatic PCB deburring device, which is designed with a workbench with a transmission slot and a receiving cavity, and a movable lifting closed baffle is designed to seal the slot and the receiving cavity, so that the grinding process is set in a closed space, so that the dust generated during the deburring process will not spread to the outside and pollute the working environment; the fixing component fixes the PCB by hinge pressing, which can conveniently fix PCBs of different thicknesses; the grinding component is designed to be movable and lifting, which is convenient for adjusting the grinding roller so that it can grind PCBs of different thicknesses; and the maintenance slot on the processing part is convenient for quickly replacing the grinding roller, which is convenient for maintenance and updating of the grinding roller; a negative pressure suction nozzle is arranged in the receiving cavity to absorb and collect a large amount of dust generated during the grinding process, which can effectively keep the processing device and the PCB board clean, thereby ensuring the processing quality, and has a strong promotion significance.

[0006] During use of the above device, the slider drives the clamp to clamp the PCB, thereby facilitating the removal of burrs. However, in the above device, the slider only drives the clamp to clamp the PCB, and using a drill to remove burrs can easily damage the PCB, affecting product quality. Therefore, in actual use, the PCB may be damaged by using a drill to remove burrs. Summary of the invention
