Description

Technical Field

[0001] This invention relates to the field of PCB manufacturing technology, specifically to a method and apparatus for manufacturing PCBs using PTFE material. Background Technology

[0002] With the rapid development of fields such as autonomous driving, smart cities, and active phased array radar, the performance requirements for printed circuit boards (PCBs) are increasing. PTFE material itself has excellent high and low temperature resistance, aging resistance, low dielectric constant, and low loss characteristics, which has led to the rapid improvement of the application of PTFE material in printed circuit boards. This has driven continuous innovation in the industry in terms of material research and development, manufacturing processes, and quality testing.

[0003] However, existing printed circuit boards produce burrs during processing. Traditional drills can damage the hole walls, affecting the product. Furthermore, manual burr removal is inefficient, resulting in slow production.

[0004] To address the aforementioned shortcomings, Chinese Patent Publication No. CN217454192U discloses a PCB drilling and deburring stacking device. This device features a PCB gripper connected to a transverse moving rod, a slider, and a longitudinal sliding groove. The transverse moving rod is movably connected to the slider, and the slider is slidably connected to the longitudinal sliding groove, allowing the gripper to hold the PCB to be processed. This enables the device to perform integrated punching and deburring operations on the PCB, improving production efficiency. Furthermore, the gripper can move longitudinally... The chute and transverse moving rod enable movement in both horizontal and vertical directions, thereby positioning the punching and deburring holes and improving work efficiency. The punching mechanism of this device is equipped with an upper and lower pressure plate set vertically by a pressing mechanism. Several connecting rods are set between the upper and lower pressure plates. The connecting rods pass through the upper pressure plate and slide and are slidably connected to it. The connecting rods are fixedly connected to the lower pressure plate. This ensures that when punching PCBs, the lower pressure plate presses down on the PCB to prevent it from warping and moving during punching, thus improving the production quality and efficiency of the device.

[0005] Furthermore, in the existing technology, Chinese patent CN217750746U discloses an automatic PCB deburring device. This device features a worktable with a transmission channel and a receiving cavity, and a movable, lifting, sealed baffle to seal the channel and cavity, placing the grinding process within a closed space. This prevents dust generated during deburring from spreading to the outside and polluting the working environment. The fixing component uses hinges to secure the PCB, easily fixing PCBs of different thicknesses. The grinding component is designed with movable lifting, facilitating adjustment of the grinding rollers to grind PCBs of varying thicknesses. A maintenance channel on the processing section allows for quick replacement of the grinding rollers, facilitating maintenance and updates. A negative pressure suction nozzle inside the receiving cavity adsorbs and collects the large amount of dust generated during grinding, effectively maintaining the cleanliness of the processing device and the PCB board, thus ensuring processing quality and possessing significant potential for widespread application.

[0006] In the above-mentioned device, the slider drives the jaws to clamp the PCB during use, which facilitates the removal of burrs. However, in the above-mentioned device, the slider only drives the jaws to clamp the PCB. Using a drill bit to remove burrs can easily damage the PCB and affect the quality of the product. Therefore, in actual use, there will be situations where the PCB is damaged due to the removal of burrs with a drill bit. Summary of the Invention

[0007] The purpose of this invention is to provide a method and apparatus for manufacturing PCBs using PTFE material, in order to solve the problem mentioned in the background art where the removal of burrs by a drill bit causes damage to the PCB.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a PTFE material PCB manufacturing apparatus, comprising a control console and a base, and further comprising:

[0017] Furthermore, a support column is fixedly installed on the inner side of the chuck, and a clamp is movably installed on the outer surface of the support column. The deburring mechanism includes the clamp, and pressure blocks are fixedly installed on both sides of the clamp.

[0018] Furthermore, a clamping plate is fixedly installed on the outer surface of the pressure block, a positioning screw is threaded on the inner side of the pressure block, and a support column is movably installed on the outer surface of the clamping plate.

[0019] Furthermore, a spiral component is fixedly installed on the outer surface of the fixing rod, an installation disc is threaded onto the outer surface of the spiral component, a pressing component is fixedly installed on the outer surface of the installation disc, and a positioning disc is fixedly installed on the outer surface of the pressing component.

[0020] Furthermore, the process includes the following steps: S1, conventional single-sided and double-sided boards; S2, conventional multilayer boards; S3, auxiliary design; S4, surface copper acquisition; S5, outline milling; S6, surface copper removal.

[0021] S1: The PTFE material is drilled, copper plating is applied, and electroplating is performed to complete the metallization of the hole and the thickening of the copper on the surface;

[0022] S2: The PTFE material is used to create an inner core board with a pattern through the inner layer pattern. The inner core board and the prepreg are then laminated into a multilayer board, and drilling, copper plating, and electroplating are performed to complete the metallization of the holes and the copper thickening of the surface.

[0023] S3: Add a pre-designed surface copper a to the outline of the exposed area of ​​the PTFE material, and cover it along the outline to form an outer graphic design;

[0024] S4: The outer layer pattern design is formed by conventional processes such as film lamination, exposure, development, and etching to create the design circuitry and surface copper a.

[0026] S6: The surface copper b is peeled off by mechanical peeling. First, a part of the surface copper b is picked up with a blade. The end of the picked-up surface copper b is clamped by a clamp. The rotating column drives the support plate to rotate. The rotating shaft drives the support column to rotate. The support column drives the clamp to rotate. By rotating, it is peeled off from the PCB, thus making a complete PCB. This achieves burr-free and shaving-free production of PTFE material, reducing the difficulty, cost and efficiency of the process.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] The specific details of the PTFE material PCB fabrication method and apparatus are as follows:

[0029] 1. The printed circuit board is placed on a plastic tray manually. The positioning rod limits the sliding block. The sliding block drives the magnet to move. The magnet clamps the printed circuit board, thereby increasing the stability of the printed circuit board and achieving the purpose of stable processing.

[0030] Furthermore, by starting the stepper motor, the stepper motor drives the output shaft to rotate, the output shaft drives the limit plate to drive the rotating column to rotate, and the rotating column drives the steel support plate to rotate. The printed circuit board is clamped by the magnetic force of the steel support plate and the magnet block to prevent the printed circuit board from falling off. The steel support plate is wrapped by the plastic plate, thereby increasing the surface friction and protecting the printed circuit board.

[0031] Furthermore, the magnet block is covered with plastic to protect the printed circuit board. By starting the hydraulic pump, the hydraulic pump drives the telescopic rod to rise and fall, the telescopic rod drives the support plate, and the support plate drives the servo motor to rise and fall, thus making it easy to adjust the height of the support column and make it easy for the clamp to hold the rough edges.

[0032] 2. By starting the servo motor, the servo motor drives the rotating shaft to drive the fixed rod to rotate, the fixed rod drives the positioning plate to drive the chuck to rotate, the chuck drives the support column to rotate, and the support column drives the clamp to rotate, which facilitates the clamping of rough edges;

[0033] Furthermore, a portion of the surface burrs is manually lifted with a cutting tool, and then a portion is manually peeled off. The burrs are held in place by clamps. The rotational speed of the steel support plate and the rotating shaft are set proportionally. The rotational shaft speed is set to a fixed 78 rpm, while the steel support plate speed is set to an adjustable range of 2 rpm to 16 rpm to ensure compatibility during peeling. This ensures that the surface burrs are positioned in a certain area below the support column at the peeling point. The clamping plate is then used to hold the burrs on the support column, and the clamping plate is fixed by positioning screws, thus fixing the clamps to the support column for stable processing.

[0034] Furthermore, the mounting plate is fixed by a screw, limited by a pressing component, and engaged with a positioning plate by a fixing rod. The positioning plate can be manually rotated, facilitating its disassembly and thus enabling personnel maintenance and increasing equipment safety. Attached Figure Description
