Example Embodiment
[0044] Example 1
[0045] This embodiment provides a PCB 1, including a first groove 2 and a second groove 3, wherein the first groove 2 is opened on one side of the PCB 1, and the groove bottom and groove wall of the first groove 2 are metallized , the first groove 2 is provided with solder paste 4, the second groove 3 is a non-metallized groove, which is spaced around the first groove 2, and the first groove 2 notch and the second groove 3 groove No graphics between ports.
[0046] In this embodiment, the PCB 1 is formed by pressing three core boards, but the number is not limited to this. For example, it can also be formed by pressing two or four core boards. Before lamination, at least one prepreg is stacked between two adjacent core boards, and the number of prepregs is selected according to the actual lamination situation.
[0047] This embodiment also provides a PCBA (Printed Circuit Board+Assembly), such as Figure 4As shown, the PCBA includes a component 5 and the ...
Example Embodiment
[0072] Embodiment 2
[0073] This embodiment provides a PCB 1, which is basically the same as the first embodiment. For the sake of simplicity, only the differences between the present embodiment and the first embodiment are described. The structure of the second groove 3 in this embodiment is different from that of the first embodiment.
[0074] like Figure 8 As shown, the second groove 3 includes an annular groove 31 and a plurality of epitaxial grooves 32. The annular groove 31 is opened on the outer circumference of the first groove 2 and is not communicated with the first groove 2. A plurality of epitaxial grooves 32 are arranged in the annular groove 31 at intervals. The outer perimeter of the groove 32 is connected with the annular groove 31. The opening position of the epitaxial groove 32 is selected according to the distribution of the circuit patterns on the surface layer of the PCB 1. Specifically, the epitaxial groove 32 avoids the circuit pattern and is set. Th...
