LGF metal dome array , which full name is Light Guide Film , it is a new design . which used to replace LED in function , in comparsion with LED , lighting Uniformity; When we add a LGF on current normal double layer or EMI dome array, it becomes a LGF dome array. It can achieve great result of light distribution.see from the design , the light under keypad is coming from the LED on PCB motherboard. We need to put about 8-10 pieces LED on each board, but if the design changed to use LGF, then we can save several LED, as well as SMT fee.What is the LGF DESIGN PRINCIPLE & What is the Advantage ?LGF, at least one surface out of front and rear surfaces of the light guide film is formed with a pattern such that density increases as distanced from a light source to allow light to be uniformly supplied to the keypad, or is concentratively formed with a pattern at a particular region of the light guide film to allow the light to be concentratively supplied to a particular region of the keypad.MajorTechnicalParameters&AdvantagesofmetalDomeArrayItemDescriptionTECHNICALINDEX1LONGLIFE-TIMERound,Oval,four-legged,triangular,rectangular,three-pointside,irregularStainlessSteel,NickelPlating,SilverPlating&goldPlatingDimpleNumbers:0/1/3/4/5dimpleLIFE-TIME:300~3000ThousandTimesIncompareofinitialvalue,Thechangerate<30%after1Mpress-test2Click%Force:100gf~450gf,Tolerance:±20gfNormalCondition3StrokeCustomizeinaccordancewithCustomer'srequirement0.12~0.6mm,Spec.variousbydifferentmetaLDOME4DimensionTolerancePositiondimensiontolerance:+/-0.1mm5GoodWeatherproofResistanceUndertheconditionsof55±2ºC,R.H.95%,Replacement24H,andthenresume2Hunderthenormalroomtemperature6GoodCorrosionResistanceHighTemperaturecanbear:+70ºCLowerTemperaturecanbear:-40ºC7TapeAdhesiveTest0.6↑(Unit:kgf/inch)8StableTapeShrinkagerateMD(%):0.5↓CD(%):0.3↓(Unit:100ºC*40mins)9SmallInstantaneousContactResistance(NickelPlating)<1Ω,(StainlessSteel)<3Ω10TotalThicknessofbasematerials0.05mm,0.075mm,0.1mm,0.125mm,0.15mm;NormalThicknessSpec.11Light-Guide-filmUniformity>75%Q1: Are you Trading company or manufacturer ?A: We are a Professional Trading & Manufacturer Integrated .Q2 : Can you offer OEM Service ?A: Surely Okay , we have Seasoned OEM service experience .Q3: what is the Lead time of sample ?A : It takes 2-7working days depends .Q4: How fast can i get the Quotation ?A: 30mins ~ 24Hours depends .Please do not hesitate to contact with us , if you have any inquires .
