Description

Technical Field

[0001] This utility model relates to the field of PCB technology, specifically to a cover paper for PCBs. Background Technology

[0002] A PCB (Printed Circuit Board) is the core carrier used to fix and interconnect electronic components in electronic devices. A PCB is an electronic interconnection platform that uses an insulating substrate (such as fiberglass or epoxy resin) as a base and forms conductive lines by etching copper foil. However, existing PCB cover paper cannot be easily folded to all four sides during use, thus failing to effectively wrap the PCB board and achieve full coverage, reducing its coverage efficiency. Furthermore, it cannot effectively guide airflow and adhere to the surface, hindering air circulation and reducing its stability, adhesion, and airflow efficiency. Therefore, we propose a PCB cover paper. Utility Model Content

[0013] like Figures 1 to 4 As shown, a PCB cover paper includes: a cover paper body 1, with horizontal folding grooves 4 respectively opened on the top of the cover paper body 1 near the front and rear sides, and vertical folding grooves 5 respectively opened on the top of the cover paper body 1 near the left and right sides, and two sets of several evenly distributed horizontal guide grooves 8 opened on the top of the cover paper body 1, and the several horizontal guide grooves 8 in each set are staggered. In this embodiment, the top of the cover paper body 1 is provided with several evenly distributed vertical guide grooves 6. The vertical guide grooves 6 and the horizontal guide grooves 8 are set at right angles, which allows it to be easily folded to four sides, thereby enabling it to effectively wrap the PCB board and achieve effective full coverage, thus improving its coverage efficiency. Implementation plan: Each group of several horizontal guide channels 8 are connected by a connecting channel 7, which is connected to the vertical guide channel 6. Several evenly distributed honeycomb channels 3 are opened on the top of the cover paper body 1, and honeycomb sheets 2 are connected in the honeycomb channels 3. A V-shaped channel 9 is connected to the left side of the vertical guide channel 6. Several evenly distributed bonding sheets 10 are attached to the bottom of the cover paper body 1, so that it can effectively guide and bond, thereby enabling effective air circulation, improving its stability, bonding and guiding efficiency.

[0014] Working principle: In use, this technical solution first folds the front and rear edges of the cover paper body 1 downwards through two horizontal folding slots 4, and folds the left and right edges of the cover paper body 1 downwards through two vertical folding slots 5. The bonding sheet 10 can be bonded to the PCB board, allowing it to be easily folded to all four sides, thus effectively wrapping the PCB board and achieving full coverage, improving its coverage efficiency. During operation, air can flow through the horizontal guide slots 8 and vertical guide slots 6, which are connected by the connecting slots 7 and blocked by the V-shaped slots 9 to achieve rapid flow. The honeycomb sheet 2 can effectively bond to it, enabling effective airflow and bonding, thus improving its stability, bonding, and airflow efficiency.
