the utility model provides a PCB board with recess, include: the device comprises a PCB, a metal ring, a first component and a second component; the metal ring and the first component are arranged on the PCB, a groove is formed in the inner side of the metal ring, and the pin of the second component is fixed in the groove.

Further, the number of the metal rings is multiple.

Further, the first component is arranged in an area enclosed by the plurality of metal rings.

Further, the depth of the groove is 0.1-0.228 mm.

Further, the surface of the metal ring is provided with a gold-plated treatment layer or a silver-plated treatment layer or a nickel-palladium-gold treatment layer or a tin-plated treatment layer or an OSP treatment layer.

Further, the number of the metal rings is greater than or equal to the number of pins of the second component.

Furthermore, the pins of the second component are fixed in the grooves in a glue bonding mode.

Further, the pins of the second component are fixed in the grooves by welding.

The utility model has the advantages that:

1. the second component can be accurately installed by accurately arranging the metal rings;

2. the pins of the second component are bonded or welded in the grooves of the metal ring, so that the second component can be fixed, the mounting efficiency of the second component is improved, meanwhile, the occupied area of the PCB can be saved through the design, holes are not needed, and the PCB is more suitable for a PCB with a compact structure;

3. the quantity of becket can set up a plurality ofly, and first component setting is in a plurality of becket region for enclosing, installs the back in the recess on the becket that corresponds with the second component, can form the overlapping of covering of first component and second component, and the area occupied of PCB board has further been saved to this mode, covers superimposed mode through the device simultaneously, enables components and parts and obtains better output effect.
