Description

Technical Field

[0001] This utility model relates to the field of electronic circuit technology, specifically to a device for roughening electronic components in PCB manufacturing. Background Technology

[0002] Coarsening refers to altering the microscopic geometry and physicochemical properties of a material surface through physical or chemical methods without affecting the bulk properties of the base material. Its purpose is to increase surface area, enhance surface energy, and strengthen mechanical interlocking forces, thereby improving the adhesion of subsequent materials (such as copper layers).

[0003] The shortcomings of existing technology: Currently, when making embedded projects, electronic components need to be embedded in the PCB board. Due to the small size of the electronic components, normal horizontal roughening lines cannot be made. Embedding electronic components without roughening into the PCB board will result in poor bonding between the electronic components and the PP, leading to cracks. Utility Model Content

[0004] The purpose of this invention is to provide a roughening device for electronic components in PCB manufacturing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB manufacturing electronic component roughening device, comprising several roughening placement areas for placing electronic components in an FR4 board, wherein the roughening placement areas are stepped around the perimeter, and the distance between opposite sides of the roughening placement areas is less than the length and width of the electronic components, wherein the electronic components are installed in the roughening placement areas and the bottom is hollowed out.

[0006] Preferably, a plurality of drainage holes are provided on the side walls around the roughening placement area, and the drainage holes are used for immersion in the roughening solution.

[0007] Preferably, the top and bottom of the FR4 plate are covered with perforated wire mesh for support and protection.

[0008] Preferably, the stepped area of ​​the roughened placement region has gaps.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This PCB manufacturing electronic component roughening device improves roughening efficiency and bonding strength of electronic components embedded in the PCB board by setting up a roughening placement area for placing electronic components, avoiding cracks, and has low manufacturing cost and can be reused.

[0010] 2. The roughening device for PCB manufacturing electronic components has several drainage holes on the side walls around the roughening placement area. The drainage holes are used for roughening solution immersion and side wall drying to improve roughening efficiency. Attached Figure Description

[0016] Example Please see Figure 1-3 As shown, this utility model provides a technical solution for a roughening device for electronic components in PCB manufacturing: It includes several roughening placement areas 3 formed in an FR4 board 1 for placing electronic components 2. The roughening placement areas 3 are stepped around their perimeter, and the distance between opposite sides of the roughening placement areas 3 is less than the length and width of the electronic components 2, ensuring that the bottom of the electronic components 2 is supported when placed in the roughening placement areas 3, preventing scratches during roughening. The electronic components 2 are installed in the roughening placement areas 3 with a hollowed-out bottom, which is beneficial for roughening and drying. Several drainage holes 4 are formed on the side walls of the roughening placement areas 3, which are used for impregnation with roughening chemicals and drying of the side walls. The top and bottom of the FR4 board 1 are covered with perforated mesh 5 for support and protection, preventing the electronic components 2 from jumping out due to spray pressure. Gaps 6 are formed in the stepped areas of the roughening placement areas 3, which is beneficial for roughening and drying of the electronic components 2.

[0017] In use, electronic component 2 is placed in roughening placement area 3 for roughening. Roughening solution is used to roughen electronic component 2. The roughening solution is fully soaked through drainage hole 4 and gap 6 to improve roughening efficiency and enhance the bonding force of electronic component 2 into PCB board.
