Abstract
The utility model relates to a moisture-proof and dust-proof circuit plate with an electronic component. The utility model comprises a printed circuit plate and the electronic element. The surface which is exposed of the printed circuit plate and the electronic element are coated with an insulating protective film. The insulating protective film is stuck with the printed circuit plate through adhesive material. The utility model has the advantages that firstly, the utility model can prevent moisture, dust and short circuit, and the utility model can be used in harsh environment, such as wet environment, dust environment, etc.; secondly, the lighting emitting effect of a light emitting element can not be influenced; thirdly, the heat radiation effect is good; fourthly, the service life of the circuit plate is improved; fifthly, the cost is low; sixthly, components can be conveniently replaced; seventhly, the utility model can be used for a circuit plate of larger area.
Description
Technical field: the utility model relates to a kind of dustproof wiring board of protection against the tide that contains electronic component.
Background technology: at present, the protection against the tide of wiring board is dustproof, it mainly is the way that adopts epoxy resin that the wiring board that contains electronic component is cured sealing or adopts shell to encapsulate, its weak point is: luminous poor with radiating effect, influence the useful life of wiring board, replacing element inconvenience, the cost height is not suitable for the bigger wiring board of area.
Summary of the invention: the utility model mainly is problems such as the protection against the tide that solves wiring board, dustproof, heat radiation and illumination effect.Printed substrate 1 and the electronic component 2 of comprising of the present utility model all covers insulating protective film 3 at the exposed surface and the electronic component of printed substrate 1, pastes by adhesive material 4 between insulating protective film 3 and the printed substrate 1 to form.
The beneficial effects of the utility model are: 1, have the effect of moistureproof dustproof anti-short circuit, can use under adverse circumstances such as humidity and dust are big; 2, do not influence the illumination effect of light-emitting component; 3, radiating effect is good; 4, improve the useful life of wiring board; 5, cost is low; 6, components and parts are changed conveniently; 7, can be used for the bigger wiring board of area.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
1 is printed substrate, the 2nd among the figure, electronic component, the 3rd, insulating protective film, the 4th, adhesive material.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
Referring to Fig. 1; all exposed printed substrate 1 and electronic components 2 of the utility model have all covered insulating protective film 3; to playing the effect of protection against the tide, dustproof and anti-short circuit between printed substrate 1 and the electronic component 2; the utility model can all can normally be used under adverse circumstances such as moist and dust is big, and the useful life of energy extension wire plate.In addition, the utility model is owing to adopt printing opacity and heat dispersion good insulation performance diaphragm 3, therefore, do not have influence on the luminous and radiating effect of the electronic component 2 of luminous, heating etc.The utility model is applicable to plug-in unit welding, surface mounted, surface exposed and contain the wiring board of electronic components such as luminous, heating.
