Abstract
The invention discloses a PCB for on-board integration of an LED. The PCB for on-board integration of the LED comprises the PCB, a positive plate and a negative plate, wherein the positive plate and the negative plate are arranged at the two ends of the PCB respectively; a positive electrode lead sheet is arranged on the positive plate and extends to the middle of the PCB; a negative electrode lead sheet is arranged on the negative plate and also extends to the middle of the PCB; the positive electrode lead sheet and the negative electrode lead sheet are respectively provided with a silver coating; the positive plate and the negative plate are respectively provided with gold plating. Compared with the traditional mode that electrodes and pole pieces of the PCB are provided with simplex plating, the PCB for on-board integration of the LED improves the light source effect of an LED lamp body, the stability of the PCB is enhanced, and the overall service life of the LED is prolonged.
Description
Technical field
The present invention relates to a kind of PCB, particularly relate to a kind of for PCB integrated on LED board.
Background technology
PCB(PrintedCircuitBoard), printed circuit board, claims again printed circuit board (PCB), printed substrate, is important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.Because it is to adopt electron printing to make, therefore be called as " printing " circuit board.Before printed circuit board occurs, the interconnection between electronic devices and components is all to rely on electric wire directly to connect realization, and now, printed circuit board (PCB) has occupied the status of empery in electronics industry.According to the circuit number of plies, PCB is divided into single sided board, double sided board and multi-layer sheet.Common multi-layer sheet is generally 4 laminates or 6 laminates, and complicated multi-layer sheet can reach tens layers.Single sided board (Single-Sided Boards) is on the most basic PCB, part concentrates on wherein one side, wire concentrates on another side, because single sided board has many strict restrictions (because only have one side in designed lines, between wiring, can not intersect and must be around path alone), so only have early stage circuit just to use this class plate.There is wiring on the two sides of double sided board (Double-Sided Boards), but will use the wire on two sides, must between two sides, have suitable circuit to connect, and " bridge " between sort circuit is called guide hole (via).Guide hole is on PCB, be full of or the duck eye of coated with metal, it can be connected with the wire on two sides, because the Area Ratio single sided board of double sided board is large one times, double sided board has solved in single sided board because the staggered difficult point (can be conducting to another side by hole) of wiring, and it is more suitable for being used in than on the more complicated circuit of single sided board.Multi-layer sheet (Multi-Layer Boards) has been used more single or two-sided wiring plates, with one two-sided do internal layer, two one sides do outer or two two-sidedly make internal layer, two one sides are made outer field printed substrate, by navigation system and adhesive material alternately together and the printed substrate that interconnects by designing requirement of conductive pattern just become four layers, six-layer printed circuit board, also referred to as multilayer printed circuit board.If most motherboard is all the structure of 4 to 8 layers.
In illuminating industry, the advantages such as LED is efficient because of having, energy-saving and environmental protection, long service life, have replaced the traditional lighting light fixture that consumes energy high, the life-span is short gradually.And in LED, PCB has very important status.At present, in the PCB of LED lamp body, conventionally only at anodal leader and negative pole leader, be provided with Gold plated Layer or silver coating, if all adopt Gold plated Layer, can cause high cost, and illumination effect is bad, if all adopt silver coating, although improved illumination effect, the positive plate on PCB, negative plate are easily subject to thermal oxidation, thereby cause LED not long useful life.
Summary of the invention
For addressing the above problem, the invention discloses a kind ofly for PCB integrated on LED board, not only can make LED illumination effect good, and electrode slice on its PCB is not oxidizable, longer service life.
Disclosed by the invention a kind of for PCB integrated on LED board, comprise PCB, positive plate and negative plate, described positive plate and negative plate are separately positioned on PCB two ends, and described positive plate is provided with anodal leader to middle extension of PCB, and described negative plate is provided with negative pole leader to middle extension of PCB.
A kind of a kind of improvement for PCB integrated on LED board disclosed by the invention, described anodal leader and negative pole leader are provided with silver coating.
A kind of another improvement for PCB integrated on LED board disclosed by the invention, described positive plate and negative plate are provided with Gold plated Layer.
Disclosed by the invention a kind of for PCB integrated on LED board, by the anodal leader and the negative pole leader that arrange, can increase the reflecting surface of LED lamp body when luminous, improve LED illumination effect; Positive plate and negative plate by arranging, can make PCB better be connected with external power source, PCB played to support effect simultaneously, guarantees that PCB's is firm; By the silver coating arranging on anodal leader and negative pole leader, can make light source better at the background colour of reflex time, and reduce cost; By the Gold plated Layer arranging on positive plate and negative plate, can guarantee that the part being connected with power supply is not oxidizable, and more firm to the support of PCB, improved the bulk life time of LED lamp body.The present invention, with respect on a traditional electrode at PCB and pole piece, single coating being set, has not only improved the little height of light source of LED lamp body, and has increased the steadiness of PCB, has extended the whole service life of LED.
