DIP (Dual I n-line P ackage)
D rau hauv - kab pob yog ib qho hluav taws xob pob nrog lub tsev nyob thiab ob txoj kab sib txuas ntawm cov hluav taws xob sib txuas. Lub pob yog dhau ntawm qhov chaw mus rau ib lub koom txoos uas luam tawm (PCB) lossis tso rau hauv lub qhov (socket).
SMD (Cov Mounted D evices )
Cov qauv siv tshuab ( SMT ) yog ib txoj hauv kev tsim hluav taws xob hauv cov khoom siv uas tau txuas los yog muab tso ncaj qha mus rau saum npoo ntawm cov ntawv cog lus Circuit Board (PCBs). Ib qho khoom siv hluav taws xob ua yog hu ua tus nplai-mount ntaus ntawv ( SMD ).
Hauv qab no yog cov pics qhia DIP thiab SMD cov lus qhia rau koj cov neeg ua tim khawv
DIP LED npo yog ib yam ntawm cov laus ib qho yog muab piv nrog cov cuab yeej tshiab ntawm SMD. Tab sis nws kuj yog ib qho ntawm cov qauv ruaj khov thiab ruaj khov rau sab nrauv coj qhia. SMD coj zaub yog ib qho tshiab technology xyoo no thiab nws tiav niam txiv ntau dua tam sim no vim nws zoo duab zoo thiab ntau dua qhov daws teeb meem.Following yog qhov sib txawv, qhov zoo thiab qhov tsis zoo ntawm lawv rau koj cov neeg ua tim khawv
Qhov zoo ntawm DIP thiab qhov tsis zoo ntawm SMD
1, Rau DIP tias txhua pixel yog ua los ntawm peb tus kheej xim (RGB) LED qij . Txhua lub teeb muaj ob txhais ko taw . Cov kauj taw ntev yog tso rau hauv PCB ncoo, yog li tom qab los ntawm lub qhov khoob rau qhov uas yuav tsis tshua mob hnyav txias. Lub SMD LED zaub muaj luv taw thiab teeb lub teeb tau txuas rau PCB ncoo uas yog yooj yim dua ua rau muaj teeb meem txias dua li ntawm DIP ib qho.
2, Qhov ntev taw pab kom qhov qij txha coj tau zoo dua ntawm kev siv cua sov. Cov cua kub zoo dua qub txhais tau tias ntev lub neej rau kev coj qhia. Yog li cov DIP LEDs yuav ua ntev tshaj li SMD ib qho los ntawm cov mus dhia ntev.
3, Lub DIP LED teeb loj yog loj, nws tso cai rau cov ntxaij vab tshaus coj tau ntau dua ci ntsa iab. Feem ntau qhov kev kajsiab DIP coj qhia muaj peev xwm ncav cuag tau 7,500nits thaum lub siab ua kom siab tshaj 10,000nits. Feem ntau rau sab nraum zoov SMD coj qhia tias qhov ci ci nyob ze li ntawm 6,000nits.
4, DIP led screens txhob siv zog tsawg dua yog muab piv nrog tib yam SMD. Feem ntau qhov kev siv fais fab ntawm DIP LED cov lus qhia yog 1/3 tsawg tshaj li qhov SMD.
Qhov zoo ntawm SMD thiab qhov tsis zoo ntawm DIP
1, Vim hais tias qhov luaj li cas ntawm qhov DIP coj teeb yog loj thiab txhua pixel yog ua los ntawm 3 qhov muag teev, yog li tsis muaj qhov chaw pub DIP coj cov zaub kom ncav cuag lub pixel suab me tshaj 10 hli. Tam sim no rau DIP LED lus tsuas yog muaj p10mm, p12mm, p16mm thiab p20mm pixel pitch muaj. Tab sis SMD LEDs me me thiab tuaj yeem tso ze ze ua ke. Lub tsev kawm ntawv qhov chaw nkag tau zoo dua qub. Lub pixel pitch ntawm SMD coj qhia tau ua los ntawm 0.9-10 hli.
2, Lub kaum sab xis pom ntawm DIP LED zaub yog me dua yog muab piv nrog lub SMD. Nws tsuas txhawb H120 ° thiab V60 ° thaum SMD LED lus pom lub kaum ntse ntse yog dav uas muaj peev xwm ncav cuag H160 ° thiab V160 °. Li ntawd, yog tias koj muaj ntse saib lub kaum ntse ntse uas yuav tsum muaj SMD LED cov ntxaij vab tshaus.
3, Kev tsim cov khoom siv thiab kev tsim khoom ntau dua rau DIP, raws li muaj 3 qhov muag teev rau txhua lub pixel, ntxig ib pixel mus rau PCB rau DIP module yuav tsawg kawg yog 3 zaug qeeb dua li ua hauj lwm rau SMD ib. Thiab lawv yog cov tshiab SMT cov tshuab tshiab uas tuaj yeem ua cov SMD kev txhim kho ntau yam ceev tshaj DIP. Qhov no yog ib qhov laj thawj uas muaj cov tsawg thiab tsawg cov tuam txhab tsim DIP LED lus qhia tam sim no.
4, Feem ntau tus nqi ntawm DIP coj cov duab yog siab dua tus SMD yog raws li qhov kev qhia tshwj xeeb thiab pixel suab.
Feem ntau lawv ob leeg muaj qhov zoo thiab qhov tsis zoo. Yog hais tias rau koj cov chaw sab nrauv installation installation uas yuav tsum tau muaj kev ci ntsa iab thiab daim ntawv thov kom ruaj ntxiv ces koj tuaj yeem xaiv lus qhia DIP LED. Yog hais tias koj xav tau kev daws teeb meem dua thiab dav saib dav dav ces SMD sawv daws yuav yog qhov zoo. Rau hauv tsev kawm ntawv sab nraud, txoj kev pom kev nrug luv luv thiab feem ntau peb nrhiav kev zoo tshaj plaws hauv daim duab thiab tsis tas yuav tsum muaj teeb ci heev, yog li SMD coj cov ntxaij vab tshaus yuav tsum yog qhov kev xaiv zoo tshaj plaws.
