Description
Technical field
The utility model relates to a kind of wiring board, belongs to wiring board manufacturing technology field.
Background technology
Pcb board is the abbreviation of printed substrate, and LED aluminum base plate and FR-4 glass wiring board all belong to PCB together.LED aluminum base plate is printed wire in the reasonable aluminium plane of thermal conductivity, then by welding electronic elements in above.The main purpose adopting aluminium base is exactly that he has good thermal diffusivity, and great power LED is larger owing to generating heat, so most of aluminium base is used for the production of LED illumination lamp.FR-4 glass fibre circuit plate is traditional electronic product wiring board, owing to having good insulation, anticorrosive, resistance to compression, the feature such as multi-sheet printed, is widely used.The product quality of LED aluminum base plate mainly considers it is the material model of aluminium, hardness, surface and thickness, and the caloric value according to product also will be followed to select the gauge size be applicable to.FR-4 glass wiring board is the product of comparative maturity, is all with FR-4 glass wiring board as many on LED display.
LED is the abbreviation of English light emitting diode (light emitting diode); its basic structure is one piece of electroluminescent chip of semiconductor material; with elargol or latex solidified on support; then chip and circuit board is connected with silver-colored line or gold thread; then surrounding epoxy sealing; play the effect of protection internal core, last mounting casing, so the anti-seismic performance of LED is good.
LED light source has energy-conservation, life-span length, stable feature, be widely used in every field, such as in daily life, the lamp of family expenses commonly uses LED as light source, by some LED lamp bead are installed on wiring board, again epoxy resin layer is arranged to wiring board skin, then wiring board is fixed on lamp socket, and then transparent or semitransparent lampshade is buckled on lamp socket.Current LED wiring board, in order to increase radiating effect, when arranging epoxy resin layer, usually can reduce the thickness of epoxy resin layer as far as possible, but the reduction of epoxy resin layer thickness makes epoxy resin layer easily come off.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome defect of the prior art, thus provides a kind of wiring board with better thermal diffusivity.
To achieve these goals, a kind of wiring board of the present utility model, comprise square aluminum wiring board body, described body external sheath has alumina layer; Described alumina layer is furnished with multiple LED lamp bead group, and each described LED lamp bead group comprises multiple LED lamp bead of setting close to each other; Described body is provided with the groove for placing LED lamp bead group, described groove is bowl-shape; The side of described body is provided with at least one depressed part, and described depressed part is provided with the groove being communicated with described body both sides; Described multiple LED lamp bead group is connected mutually, and in each LED lamp bead group, described multiple LED lamp bead is parallel with one another.
Described body offers wiring hole.
Described depressed part is two.
One end of described body is provided with locating notch.
Adopt technique scheme, wiring board of the present utility model, body arranges depressed part, and groove, when wiring board is installed after LED lamp bead group outside increase epoxy resin protective layer time, first the full described depressed part of epoxy resin filling is made, then epoxy resin flows to body opposite side by groove, groove can play drainage, after epoxy resin is air-dry, owing to being filled with epoxy resin and epoxy resin is communicated to the epoxy resin layer of body opposite side by groove in depressed part, can hold at body surface after making epoxy resin air-dry, difficult drop-off, and then when the thickness of epoxy resin layer can be reduced, improve LED circuit board radiating effect, ensure that epoxy resin layer can not come off.

Detailed description of the invention
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1,2,3, 4, the present embodiment provides a kind of wiring board, and comprise square aluminum wiring board body 1, described body external sheath has alumina layer 2; Described alumina layer 2 is furnished with multiple LED lamp bead group 3, and each described LED lamp bead group 3 comprises multiple LED lamp bead of setting close to each other; Described body 1 is provided with the groove 11 for placing LED lamp bead group, described groove 11 is bowl-shape; The side of described body 1 is provided with at least one depressed part 12, and described depressed part 12 is provided with the groove 13 being communicated with described body 1 both sides; Described multiple LED lamp bead group 3 is connected mutually, and in each LED lamp bead group 3, described multiple LED lamp bead is parallel with one another.
Described body 1 offers wiring hole 14.
Described depressed part 12 is two.
One end of described body is provided with locating notch 15.
Adopt technique scheme, wiring board of the present utility model, body arranges depressed part, and groove, when wiring board is installed after LED lamp bead group outside increase epoxy resin protective layer time, first the full described depressed part of epoxy resin filling is made, then epoxy resin flows to body opposite side by groove, groove can play drainage, after epoxy resin is air-dry, owing to being filled with epoxy resin and epoxy resin is communicated to the epoxy resin layer of body opposite side by groove in depressed part, can hold at body surface after making epoxy resin air-dry, difficult drop-off, and then when the thickness of epoxy resin layer can be reduced, improve LED circuit board radiating effect, ensure that epoxy resin layer can not come off.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
