Primer is laid in die bond functional areas surface and recessed point；
LED chip is bonded on the primer.The primer is conductive silver glue.
Preferably, the metal base is copper, iron or its alloying metal sheet material.
Preferably, the metal base is with a thickness of 0.12 ~ 0.2mm.
The metal base further includes the conductive feet connecting with die bond functional areas.
Preferably, the recessed point shape is lower spill, including but not limited to regular circle shapes, triangle, quadrangle, five
Side shape or hexagon.
Preferably, backbone metal structure division encapsulating ambroin and form bowl, the ambroin include but
It is not limited to PPA or EMC material.
Preferably, the mode of the recessed point array arrangement is rectangular array or annular array.
The utility model has the following beneficial effects:
This implementation is novel to arrange recessed point on metallic support die bond functional areas, and the recessed point is equal in each unit
Have arrangement, carry out a conductive silver glue in the recessed area, be filled into conductive silver glue in recessed point, increase conductive silver glue with
Rack surface is bonded contact surface.Recessed point is set as different shape, to be suitble to use under different condition, the recessed fiber crops of polygon
Point can effectively increase the contact surface of conductive silver glue, and effectively fixed conductive silver glue is applied to display encapsulation, can substantially improve conduction
The risk of the red failure of display LED caused by elargol removing.

Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below, but the utility model
Protection scope be not limited to these examples, it is all without departing substantially from the utility model design change or equivalent substitute be included in
Within the protection scope of the utility model.
Embodiment 1
This bracket uses PPA or EMC material, but is not limited to PPA and EMC material, can be other resinae insulating materials；
The backbone metal substrate is copper, iron or its alloying metal sheet material, thickness about 0.12-0.2mm, in punch forming
When die bond functional areas utilize the recessed point of mould punching, length and width dimensions 0.01-0.08mm, depth 0.02-0.06mm, recessed fiber crops
Point quantity 3-25 are lined up array；
Primer is laid in die bond functional areas surface and recessed point；LED chip is bonded on the primer.The primer is to lead
Electric elargol.
The recessed point shape is the recessed of the regular shapes such as recessed rectangle, triangle, circle, pentagon, hexagon
The cross section in hole, the recessed point is trapezoidal, inverted trapezoidal, but is not limited to above several shapes, as long as in die bond functional areas
The concave shape of production array arrangement belongs to protection scope；
Transverse groove or salient point can also be arranged in the recessed point side wall, it is therefore intended that increase the knot of primer and recessed point
With joint efforts, the transverse groove is one or more, and the salient point is multiple.As shown in Figure 6.
The recessed point is arranged as array arrangement, and array manner is rectangular array, annular array, linear array or interlocks
Array, but above several array arrangements are not limited to, all concave shape arrangements for making 1 or more in die bond functional areas are equal
Belong to protection scope.
It after the backbone metal substrate punches recessed point first, then completes functional areas punching, stretch, be then electroplated,
Form bracket material.Injection step is carried out again, forms the encapsulating of plastic packaging bowl, is finally carried out pin bending and is formed bracket finished product；
