Description

Substrate stacked breathable structure

This creation is a substrate-stacked air-permeable structure, especially one that protects the substrate on the substrate through the arrangement of the receiving element and the air-permeable part, and can conduct heat, and can ventilate and dissipate heat in the upper and lateral directions.

When processing is required, the substrate and the carrier are processed, and then the substrate can be separated from the carrier for application. The process is often used for intermediate products such as printed circuit boards.

When the conventional sheet-like substrate is heated on the carrier, it often suffers from the lack of surface unevenness due to thermal expansion. Therefore, the conventional maturation of the soft board material is due to the fact that the lower surface of the metal heat-conducting plate is provided at both ends The steel strip is provided with fine holes, so that during the production process, the soft plate material is flatly attached to the upper surface of the metal heat conduction plate, and the post-winding process is performed, and the soft plate material is always It is laminated with the metal heat conduction plate to achieve its flatness and does not require the use of glue to locate the soft plate material; however, the method disclosed above is not easy to process the thin holes on the side ends of the steel strip, which leads to the manufacture of the steel strip The process and cost are increased, and the thickness of the steel strip required is relatively high, which makes the overall volume after coiling bulky, which makes the storage and transportation efficiency poor; moreover, its installation can only conduct heat convection at the side end.

As far as the setting of the receiving element 2 is concerned, it can be set on the upper or lower end surface of the substrate 1; thereby, when the substrate 1 is directly stacked or rolled up and stacked, the receiving element 2 can abut against it. At the air-permeable portion 11 of the adjacent substrate 1, as shown in Figure 3, air circulation is provided between the adjacent substrates 1, so that heating and heat dissipation can be uniformized. In the lateral direction, the two-phase The air between the adjacent substrates 1 will be convective from the receiving element 2 between them, through the gap 12 above or below it, through the air-permeable portion 11, to another corresponding gap 12, so that heat can bypass the receiving element 2 And disperse

In addition, since the heat has the characteristic of flowing upward due to its density, when the air-permeable portion 11 is a through hole, as shown in Figure 3, because the receiving element 2 abuts against the air-permeable portion 11 of the adjacent substrate 1 At the same time, a gap 12 is also formed, so the heat can also directly pass through the gap 12 and convection upwards, so as to enhance the ventilation and heat dissipation effect of the present invention.
