Detailed description of the invention
In order to allow those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with the accompanying drawings to this Utility model is further elaborated.
As shown in Figures 4 to 6, the LED circuit board of a kind of side paster, including the wiring board 1 of 2N Rotating fields be fixed on Wiring board sidewall and the pad 2 connected with wiring board internal layer circuit circuit.Described multiple pads 2 are separately positioned on wiring board Sidewall, by the assembling being implemented in combination with LED chip and wiring board of pad Yu LED chip.
The wiring board 1 of described 2N Rotating fields includes two sandwich circuit boards and (N-1) layer internal layer circuit plate, its typesetting and pressing Order is followed successively by outer-layer circuit plate, (N-1) layer internal layer circuit plate, outer-layer circuit plate.The sidewall of described wiring board 1 is provided with N number of Boring 11, N number of boring 11 is separately positioned between outer-layer circuit plate and internal layer circuit plate, internal layer circuit plate and internal layer circuit plate it Between.Described boring is drilled in the sidewall of wiring board by boring nozzle, facilitates postorder production and processing, improves the adhesive force of pad.
Described pad 2 be fixed on by the way of heavy copper is electroplated wiring board 1 sidewall and with wiring board internal layer circuit circuit Connection.The lateral part of pad is vertical with wiring board plate face.Needs according to client and the requirement of LED chip, specifically arrange pad Quantity, the quantity of general pad is multiple.Described pad 2 includes being arranged on wiring board sidewall and hanging down with wiring board plate face Straight weld part 21 and be connected to fixing for pad connecting portion 22 in the circuit board with weld part, described connecting portion 22 with Weld part 21 is structure as a whole.Described connecting portion 22 is arranged in boring 11, between the upper surface of wiring board 1 and lower surface.
