SMT yog dab tsi?

Feem ntau ntawm cov khoom siv hluav taws xob ua lag luam yog txhua yam hais txog kev sib txuas sib txuas hauv cov chaw me me.Txhawm rau ua qhov no, cov khoom yuav tsum tau txuas ncaj qha mus rau lub rooj tsav xwm hauv Circuit Court es tsis yog xaim.Qhov no yog qhov tseem ceeb dab tsi nto mount technology yog.

Puas yog Surface Mount Technology tseem ceeb?

Feem ntau ntawm cov khoom siv hluav taws xob niaj hnub no yog tsim los ntawm SMT, lossis cov cuab yeej siv saum npoo av.Cov cuab yeej siv thiab cov khoom siv SMT muaj ntau qhov zoo dua li cov kab hluav taws xob ib txwm muaj;Cov khoom siv no hu ua SMDs, lossis cov khoom siv saum npoo av.Cov txiaj ntsig zoo no tau ua kom ntseeg tau tias SMT tau tswj hwm lub ntiaj teb PCB txij li nws lub tswv yim.

Qhov zoo ntawm SMT

• Lub ntsiab kom zoo dua ntawm SMT yog tso cai rau automated ntau lawm thiab soldering.Qhov no yog tus nqi thiab txuag lub sijhawm thiab tseem tso cai rau kev sib tw ntau dua.Kev txuag ntawm cov nqi tsim khoom feem ntau dhau mus rau cov neeg siv khoom - ua kom muaj txiaj ntsig zoo rau txhua tus.
• Tsawg qhov yuav tsum tau drilled ntawm Circuit Court boards
• Cov nqi qis dua qhov sib npaug ntawm qhov sib npaug
• Ob sab ntawm lub rooj tsav xwm Circuit Court tuaj yeem muaj cov khoom tso rau ntawm nws
• SMT Cheebtsam yog deb me me
• Cov khoom siv ntau dua
• Kev ua tau zoo dua nyob rau hauv co thiab vibration tej yam kev mob.

Disadvantages ntawm SMT

• Qhov loj lossis lub zog loj yog qhov tsis tsim nyog tshwj tsis yog siv los ntawm lub qhov.
• Kev kho ntawm phau ntawv tuaj yeem nyuaj heev vim qhov tsis tshua muaj qhov loj ntawm cov khoom.
• SMT tuaj yeem tsis tsim nyog rau cov khoom siv uas tau txais kev sib txuas thiab kev sib txuas tsis tu ncua.

Cov khoom siv SMT yog dab tsi?

Surface mount devices lossis SMDs yog cov khoom siv uas siv thev naus laus zis nto.Cov khoom siv ntau yam siv tau tsim tshwj xeeb los ua kom ncaj qha rau ntawm lub rooj tsavxwm es tsis yog xaim ntawm ob lub ntsiab lus, ib yam li cov ntaub ntawv los ntawm lub qhov tshuab.Muaj peb pawg tseem ceeb ntawm SMT Cheebtsam.

Passive SMDs

Feem ntau ntawm passive SMDs yog resistors lossis capacitors.Cov pob ntau thiab tsawg rau cov no yog cov qauv zoo, lwm yam khoom xws li coils, muaju thiab lwm yam zoo li yuav tsum muaj ntau qhov tshwj xeeb.

Integrated circuits

Raucov ntaub ntawv ntau ntxiv txog kev sib xyaw ua ke hauv circuits feem ntau, nyeem peb blog.Hais txog SMD tshwj xeeb, lawv tuaj yeem sib txawv raws li qhov xav tau kev sib txuas.

Transistors thiab diodes

Transistors thiab diodes feem ntau pom nyob rau hauv ib lub hnab yas me me.Ua cov ntawv sib txuas thiab kov lub rooj tsavxwm.Cov pob no siv peb lub taub hau.

Keeb kwm luv luv ntawm SMT

Nto mount thev naus laus zis tau siv dav hauv xyoo 1980s, thiab nws qhov chaw tsuas yog loj hlob los ntawm qhov ntawd.Cov neeg tsim khoom PCB tau pom sai sai tias SMT cov khoom siv tau zoo dua los tsim dua li cov txheej txheem uas twb muaj lawm.SMT tso cai rau kev tsim khoom kom ua tau zoo heev.Yav dhau los, PCBs tau siv cov xov hlau los txuas lawv cov khoom.Cov xov hlau no tau muab los ntawm tes siv txoj hauv kev los ntawm qhov.Qhov nyob rau saum npoo ntawm lub rooj tsavxwm muaj cov xov hlau threaded los ntawm lawv, thiab cov no, nyob rau hauv lem, txuas cov khoom siv hluav taws xob ua ke.Ib txwm PCBs xav tau tib neeg los pab hauv kev tsim khoom.SMT tshem tawm cov kauj ruam nyuaj no los ntawm cov txheej txheem.Cheebtsam tau hloov pauv mus rau cov ntaub qhwv ntawm cov laug cam xwb - yog li 'nto mount'.

SMT txuas rau

Txoj kev uas SMT qiv nws tus kheej rau mechanization txhais tau hais tias kev siv kis tau sai thoob plaws hauv kev lag luam.Tag nrho cov txheej txheem tshiab tau tsim los nrog rau qhov no.Cov no feem ntau me dua lawv qhov sib npaug ntawm lub qhov.SMDs tuaj yeem muaj tus lej ntau dua.Feem ntau, SMTs kuj tseem muaj ntau qhov sib txuam ntau dua li ntawm lub qhov hluav taws xob Circuit Court boards, tso cai rau cov nqi tsheb thauj mus los qis dua.Zuag qhia tag nrho, cov khoom siv tsuas yog ntau npaum li cas thiab kev lag luam.Lawv muaj peev xwm ntawm kev siv technology tshiab uas tsis tuaj yeem xav txog kev siv los ntawm lub qhov.

Kev siv hauv xyoo 2017

Surface mount los ua ke muaj yuav luag tag nrho domination ntawm PCB tsim txheej txheem.Tsis tsuas yog lawv muaj peev xwm tsim tau, thiab me me rau kev thauj mus los, tab sis cov khoom siv me me no kuj muaj txiaj ntsig zoo.Nws yog ib qho yooj yim pom vim li cas PCB ntau lawm tau txav los ntawm txoj kev xaim los ntawm lub qhov.
