Description

Technical Field

[0001] This invention relates to the technical field of micropore directional filling and positioning structure for black hole plating solution, specifically a micropore directional filling and positioning structure for black hole plating solution used in FPC. Background Technology

[0002] Black hole metallization is an important process for metallizing vias in printed circuit boards (PCBs). It utilizes nano-carbon black particles to adsorb onto the walls of micropores and blind vias to form a conductive carbon film, replacing the traditional chemical copper plating process. This process offers advantages such as simple wastewater treatment and minimal damage to flexible substrates, and is widely used in the fabrication of micro-blind vias in flexible printed circuit boards (FPCs) and high-displacement (HDI) systems. With the miniaturization of electronic products, the pore size of FPC micropores is continuously decreasing, and the aspect ratio of blind vias is increasing, placing higher demands on the chemical penetration, fluid exchange within the vias, and colloidal dispersion stability of black hole tooling.

[0003] In existing microporous directional filling and positioning structures for black hole medicines, the nano-carbon particles of the black hole medicine tend to settle and accumulate in the base and at the bottom of the negative pressure chamber. The flexible clamping frame is displaced, twisted, and misaligned due to the impact of the medicine jet. At the same time, the agglomerated particles already formed in the circulating medicine directly enter the guide hole ring, causing the hole ring to be blocked. Summary of the Invention

[0004] The purpose of this invention is to provide a micropore directional filling and positioning structure for black hole solution used in FPC plating, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A micropore directional filling and positioning structure for a black hole plating solution used in FPC (Flexible Printed Circuit) includes an FPC carrier substrate, planar positioning posts, an ultrasonic vibrating plate, and a directional filling assembly. The planar positioning posts are fixed at mounting points on the FPC carrier substrate, and the ultrasonic vibrating plate is positioned at a positioning point on each planar positioning post. The planar positioning posts and the ultrasonic vibrating plate are mounted at assembly points on the directional filling assembly. The assembly also includes... The flow guiding assembly is mounted on the FPC carrier plate base; An anti-clogging component is disposed on the FPC carrier plate base; The FPC carrier base has a shunt cavity at the shunt point, a flexible clamping frame is assembled at the bottom of the FPC carrier base, a microporous directional flow guide frame is fixed at the mounting point on the flexible clamping frame, an ultrasonic disturbance module is provided at the buckle on the microporous directional flow guide frame, an ultrasonic vibration plate is provided at the bottom of the ultrasonic disturbance module, and a negative pressure manifold is installed inside the ultrasonic vibration plate.

[0006] The micropore directional filling and positioning structure of the black hole solution for FPC plating as described above: the micropore directional guide frame is installed on the negative pressure manifold through a flexible clamping frame.

[0007] As described above, the micro-pore directional filling and positioning structure for black hole solution used in FPC plating: the flow distribution cavity passes through the FPC carrier plate base threaded through the micro-pore directional flow guide frame.

[0008] The micropore directional filling and positioning structure of the black hole solution for FPC plating as described above: the flow guiding component includes a polyester column fixedly installed on a flexible clamping frame, and a flow-diverting annular hole ring is fixed at the connection point on the micropore directional flow guiding frame.

[0009] The micropore directional filling and positioning structure of the black hole solution for FPC plating as described above: the diversion annular hole ring and the micropore directional guide frame are mounted on the ultrasonic disturbance module by a flexible clamping frame.

[0010] The micropore directional filling and positioning structure of the black hole solution for FPC plating as described above: the anti-clogging component includes a tapered spiral rod slidably connected to the middle of the FPC carrier base, and a spiral blade is connected to the fixed part of the tapered spiral rod.

[0011] The micropore directional filling and positioning structure of the black hole solution for FPC plating as described above: the anti-clogging component also includes a built-in ultrasonic generator installed on the diversion and collection cavity, and a vibrating plate is provided at the drive point of the built-in ultrasonic generator.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: When the black hole solution first enters the diversion and collection cavity, the suspended vibrating plate in the cavity, together with the built-in ultrasonic generator, performs pre-ultrasonic dispersion treatment on the solution, breaking up the nano carbon black agglomerates, making the colloid uniformly dispersed, reducing bubble residue, and preventing the boundary layer from being too thick and the carbon film at the bottom of the hole from being too thin. After being homogenized by ultrasound, the solution completes uniform diversion and pressure stabilization in the diversion and collection cavity. Subsequently, the solution enters the diversion annular hole ring to achieve primary and secondary diversion and directional jet spraying.

[0013] During the injection of black hole solution into the FFPC carrier substrate cavity, the rotating disturbance of the conical spiral rod and spiral blades shears, disperses, and prevents sedimentation of the black hole solution within the cavity, inhibiting the agglomeration of nano carbon black particles and the accumulation of scale at the bottom. This prevents the black hole solution from settling, accumulating scale, and agglomerating particles. Before entering the FPC carrier substrate cavity, the black hole solution is first passed through the diversion and collection cavity to achieve overall uniform diversion and pressure stabilization, ensuring consistent flow rate and pressure throughout the solution. After pressure stabilization, the solution then enters the diversion annular ring for primary and secondary diversion.

[0014] The micro-orifice directional guide frame and the diversion annular orifice ring are assembled as a single flow guiding component. They are suspended and fixed above the ultrasonic disturbance module by multiple polyester columns set on the flexible clamping frame. The micro-orifice directional guide frame and the diversion annular orifice ring can vibrate synchronously with the ultrasonic disturbance module at high frequency through the flexible clamping frame. At the same time, the polyester columns achieve rigid guidance, anti-torsion limit, and anti-displacement, and prevent metal ion contamination of the medicine. The black hole medicine first enters the diversion and collection cavity to complete uniform diversion and pressure stabilization, and then enters the diversion annular orifice ring for primary and secondary diversion and directional spraying. It is then precisely guided by the micro-orifice directional guide frame to be aligned with the FPC micro-orifice. Attached Figure Description

[0019] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0020] Please see Figures 1-5A micropore directional filling and positioning structure for black hole solution used in FPC plating is proposed, including an FPC carrier base 1, a planar positioning post 2, an ultrasonic vibration plate 7, and a directional filling component.

[0021] A planar positioning post 2 is fixed at the mounting point on the FPC carrier plate base 1. An ultrasonic vibration plate 7 is set at the positioning point on the planar positioning post 2. The planar positioning post 2 and the ultrasonic vibration plate 7 are installed at the assembly point on the directional filling assembly. A flow guiding assembly is installed on the FPC carrier plate base 1. An anti-clogging assembly is set on the FPC carrier plate base 1. The FPC carrier base 1 is fixedly installed on the ultrasonic vibration plate 7 by the planar positioning column 2. The black hole solution is injected into the cavity of the FPC carrier base 1. The ultrasonic vibration plate 7 transmits mechanical vibration to the FPC carrier base 1 through the planar positioning column 2, which drives the FPC board inside the FPC carrier base 1 to vibrate, realizing the FPC plating hole vibration auxiliary treatment. Among them, the FPC carrier base 1 has a diversion and collection cavity 8 at the diversion point, the bottom of the FPC carrier base 1 is equipped with a flexible clamping frame 3, the mounting point of the flexible clamping frame 3 is fixed with a microporous directional guide frame 4, the buckle of the microporous directional guide frame 4 is provided with an ultrasonic disturbance module 5, the bottom of the ultrasonic disturbance module 5 is provided with an ultrasonic vibration plate 7, and a negative pressure collection cavity 6 is installed inside the ultrasonic vibration plate 7.

[0022] In this embodiment, before the black hole solution is injected into the cavity of the FPC carrier base 1, it is first uniformly diverted and stabilized through the diversion and collection cavity 8 to ensure uniform flow and consistent pressure. After diversion, the black hole solution is vertically oriented and guided by the micro-hole directional guide frame 4 to accurately align with the FPC micro-hole array, thereby achieving forced filling of the holes and displacement of air in the holes. The flexible clamping frame 3 clamps the FPC, prevents warping, and ensures accurate alignment. During the process of the solution entering the FPC carrier base 1 and contacting the FPC micro-holes, it is continuously treated by the bottom ultrasonic disturbance module 5 with high-frequency vibration to break the micro-hole fluid boundary layer, inhibit carbon particle agglomeration, and accelerate the precipitation of bubbles in the holes. Finally, a stable negative pressure difference is formed below the FPC board through the negative pressure collection cavity 6, allowing the black hole solution to directionally penetrate the micro-holes from top to bottom.

[0023] Preferably, the microporous directional flow guide frame 4 is installed on the negative pressure manifold 6 through the flexible clamping frame 3, and the microporous directional flow guide frame 4 is elastically floating at the upper cavity position of the negative pressure manifold 6 through the flexible clamping frame 3; so that the microporous directional flow guide frame 4 can generate a small elastic floating displacement relative to the negative pressure manifold 6.

[0024] Preferably, the diversion and collection cavity 8 is threaded through the FPC carrier plate base 1 onto the micro-hole directional guide frame 4. When the black hole medicine is injected into the equipment cavity, it first completes uniform diversion and pressure stabilization through the diversion and collection cavity 8, so that the medicine pressure and flow distribution are consistent. The diverted black hole medicine enters the micro-hole directional guide frame 4, and achieves vertical directional jet guidance through the internal holes of the micro-hole directional guide frame 4, accurately aligning with the FPC micro-holes on the FPC carrier plate base 1 below.

[0025] Please refer to Figure 2 and Figure 3 In this embodiment, the flow guiding component includes a polyester column 10 fixedly installed on the flexible clamping frame 3, and a diversion annular hole ring 9 is fixed at the connection point on the microporous directional flow guiding frame 4.

[0026] The polyester column 10 is fixedly installed on the flexible clamping frame 3, and the diversion annular hole ring 9 is distributed and installed inside the microporous directional guide frame 4. When the diverted black hole medicine enters the microporous directional guide frame 4, the black hole medicine achieves vertical directional jet guidance through the hole position of the diversion annular hole ring 9 inside the microporous directional guide frame 4.

[0027] Preferably, the diversion annular ring 9 and the micro-orifice directional guide frame 4 are mounted on the ultrasonic disturbance module 5 via a flexible clamping frame 3. The micro-orifice directional guide frame 4 and the diversion annular ring 9 are mounted on the ultrasonic disturbance module 5 via polyester pillars 10 on the flexible clamping frame 3. The micro-orifice directional guide frame 4 and the diversion annular ring 9 are assembled as a single flow guiding component. The micro-orifice directional guide frame 4 and the diversion annular ring 9 are suspended and fixed above the ultrasonic disturbance module 5 via multiple polyester pillars 10 on the flexible clamping frame 3. The micro-orifice directional guide frame 4 and the diversion annular ring 9 can vibrate synchronously with the ultrasonic disturbance module 5 at high frequency via the flexible clamping frame 3. At the same time, the polyester pillars 10 achieve rigid guidance, anti-torsion limiting, and anti-deviation, preventing metal ion contamination of the solution. The black hole solution first enters the diversion and collection cavity 8 to complete uniform diversion and pressure stabilization, and then enters the diversion annular ring 9 for primary and secondary diversion and directional spraying. It is then precisely guided and aligned with the FPC micro-orifices via the micro-orifice directional guide frame 4.

[0028] Please refer to Figure 4 and Figure 5 In this embodiment, the anti-clogging component includes a tapered spiral rod 11 slidably connected to the middle of the FPC carrier plate base 1, and a spiral blade 12 is connected to the fixed part of the tapered spiral rod 11.

[0029] During the injection of black hole medicine into the cavity of FFPC carrier plate base 1, the rotational disturbance of the conical spiral rod 11 and spiral blade 12 shears, disperses and prevents sedimentation of the black hole medicine in the cavity, inhibiting the agglomeration of nano carbon black particles and the accumulation of scale at the bottom, and avoiding the sedimentation, scale accumulation and particle agglomeration of black hole medicine. Before entering the cavity of FPC carrier plate base 1, the black hole medicine is first passed into the diversion and collection cavity 8 to complete the overall uniform diversion and pressure stabilization, so that the medicine flow and pressure are consistent throughout the entire range. After pressure stabilization, the medicine enters the diversion annular hole ring 9 for primary and secondary diversion, and forms a directional jet through the central main channel hole and the circumferentially inclined auxiliary spray hole, realizing precise, uniform and multi-angle micro-hole directional injection drug delivery.

[0030] Please refer to Figure 4 and Figure 5 In this embodiment, the anti-clogging component also includes a built-in ultrasonic generator 13 installed on the diversion and collection cavity 8, and a vibrating plate 14 is provided at the drive position of the built-in ultrasonic generator 13.

[0031] The built-in ultrasonic generator 13 is installed on the diversion and collection cavity 8, so that the vibrating plate 14 on the diversion and collection cavity 8 is suspended inside the diversion and collection cavity 8. When the black hole medicine first enters the diversion and collection cavity 8, the suspended vibrating plate 14 in the cavity, together with the built-in ultrasonic generator 13, performs pre-ultrasonic dispersion treatment on the medicine, breaks up the nano carbon black agglomerates, makes the colloid uniformly dispersed, reduces the residual bubbles, and prevents the boundary layer from being too thick and the carbon film at the bottom of the hole from being too thin. After being homogenized by ultrasound, the medicine completes uniform diversion and pressure stabilization in the diversion and collection cavity 8. Then the medicine enters the diversion annular hole ring 9 to achieve primary and secondary diversion and directional jet spraying.

[0032] As can be seen from the above, during use, the clamping frame 3 clamps the FPC, prevents warping, and ensures precise alignment. When the solution enters the FPC carrier plate base 1 and comes into contact with the FPC micropores, it is continuously treated by the bottom ultrasonic disturbance module 5 with high-frequency vibration, which breaks the micropore fluid boundary layer, inhibits carbon particle agglomeration, and accelerates the precipitation of bubbles in the pores. A stable negative pressure difference is formed below the FPC plate through the negative pressure manifold 6. The vibrating plate 14 on the diversion and collection cavity 8 is suspended inside the diversion and collection cavity 8. When the black hole solution first enters the diversion and collection cavity 8, the suspended vibrating plate 14 in the cavity, together with the built-in ultrasonic generator 13, performs pre-ultrasonic dispersion treatment on the solution, breaks up the nano carbon black agglomerate particles, makes the colloid dispersed evenly, and reduces the residue of bubbles.

[0033] The diversion annular rings 9 are distributed and installed inside the microporous directional guide frame 4. When the diverted black hole medicine enters the microporous directional guide frame 4, the black hole medicine is guided vertically through the holes of the diversion annular rings 9 inside the microporous directional guide frame 4. The microporous directional guide frame 4 and the diversion annular rings 9 are assembled as a whole into a guide component. The whole is suspended and fixed above the ultrasonic disturbance module 5 by multiple polyester columns 10 set on the flexible clamping frame 3. The microporous directional guide frame 4 and the diversion annular rings 9 can vibrate synchronously with the ultrasonic disturbance module 5 through the flexible clamping frame 3. At the same time, the polyester columns 10 achieve rigid guidance, anti-torsion limit, and anti-deviation.
