Tact hloov 6 × 6 SMTyog ib qho ntawm cov khoom siv hluav taws xob zoo tshaj plaws, vim tias siv dav hauv kev siv, tau txais kev pom zoo los ntawm cov neeg siv khoom feem ntau, txawm li cas los xij cov khoom lag luam zoo li tus neeg zoo, tsis muaj qhov zoo tag nrho, muaj qee yam tsis xws luag thiab tsis muaj peev xwm.Muaj qee qhov teeb meem nrog cov khoom no, tab sis nws yog OK nyob rau hauv cov nqe lus ntawm kev siv tag nrho thiab zoo.Cov teeb meem tuaj yeem tswj tau thiab zam, xws li hauv kev siv thiab tu.Kev siv thiab tu kom zoo tuaj yeem ua rau lub neej ntev.Cov hauv qab no feem ntau yog hais txog tACT hloov 6 × 6 teeb meem tshwm sim.
Tact hloov 6 × 6 SMT teeb meem tshwm sim
Tus nqi siab tsis kam: tam sim no, ntau tus neeg siv khoom tsis paub txog tus nqi tiv thaiv ntawm TACT hloov 6 × 6.Feem ntau, qhov kev tiv thaiv tus nqi ntawm peb qhov kev hloov pauv yog tswj hauv qab 30m Ohms, yog li kev sib cuag thiab lub neej ntawm kev hloov pauv tau zoo heev, tab sis qee qhov hloov pauv yog qhov muaj txiaj ntsig zoo tom qab lub qhov cub kub thiab lub neej sim.Dab tsi yog qhov cuam tshuam ntawm kev ua haujlwm siab ntawm tACT hloov 6 × 6?Yog tias qhov kev tiv thaiv siab, qhov chaw tiv tauj ntawm lub shrapnel thiab tus PIN PIN ntawm tus tes hloov yog me me.Qhov chaw sib cuag me me yuav ua rau qhov hloov tsis sib cuag.Thaum tus hloov tsis tau hu, nws yuav phem.
Yog li ntawd, peb yuav tsum tau ceev faj txog qhov kev tiv thaiv ntawm kev hloov, shrapnel thiab PIN rau electroplating yuav tsum muaj siab, electroplating zoo kuj tus nqi yuav tsawg.Hloov hauv kev sim lub neej, qhov saum npoo ntawm cov shrapnel yuav hnav, yog tias cov plating yog nyias, qhov tsis kam yog siab, qhov hloov tsis zoo.
Ob, adhesion: ultra-nyias TACT hloov 6 × 6 feem ntau hu ua nyias zaj duab xis hloov, nyias hloov yuav tsum nyias zaj duab xis, thiaj li ua tiav nyias nyias.Tab sis ntau zaj duab xis kub kev ua haujlwm tsis zoo, tom qab lub cub tawg yuav poob tawm qhov tshwm sim.Peb cov lus hais tias adhesion, qhov tseeb, zaj duab xis viscosity thiab ntshuam PI zaj duab xis zoo heev tswj qhov no, nws adhesion yog 400 g, heev accord nrog hloov mus siv, yuav ua li cas dhau lub teeb feem ntau poob, yog hnyav heev yuav hloov raws li taag. , ntau manufacturers thiaj li yuav txuag tau nqi los xaiv domestic pheej yig PI zaj duab xis, hloov yog yooj yim heev rau adhesion teeb meem, Qhia txhua tus neeg mus nug cov chaw tsim tshuaj paus zoo ua ntej yuav.
Peb, tom qab lub cub tawg tsis tuaj yeem nias: qhov hloov pauv zoo, tom qab rov qab vuam kev paub tsis tuaj yeem nias, tsis zoo heev.Ntau tus neeg siv khoom kuj tau teb rau qhov teeb meem no, yog li cas yog vim li cas?Lub patch hloov yog snug nrog PCB, thiab tus PIN yog glued rau solder paste.Yog hais tias lub qhov ntawm cov hlau mesh loj dua me ntsis, cov tshuaj txhuam hniav yog yooj yim ntws mus rau sab hauv ntawm qhov hloov.Yog tias muaj lub cev txawv teb chaws nyob rau sab hauv ntawm qhov hloov pauv, nws yeej yuav cuam tshuam nws txoj kev mus ncig.Qhov feem ntau yog tsis txav.Lwm qhov xwm txheej yog tias qhov hloov pauv sealing kev ua haujlwm tsis zoo, flux rau hauv qhov hloov hauv, yog li qhov teeb meem tuaj.
Yog li ntawd, nws tau hais tias cov neeg siv khoom yuav tsum tau them sai sai rau qhov teeb meem no hauv cov txheej txheem tsim khoom.
Plaub, lub hau tawm: nyob rau hauv cov txheej txheem tsim khoom, yuav muaj cov kua dej tawm ntawm lub hau nrog cov neeg siv khoom hloov pauv.Yuav ua li cas hloov lub hau npog zoo?Ua ntej tshaj plaws, peb yuav tsum nkag siab txog cov qauv ntawm kev hloov pauv, lub hau npog ntawm qhov hloov pauv yog qab lub hau, qhov no yog ib lab xyoo ntawm cov txheej txheem tsim khoom tas li.
Yog tias koj paub txog nws, koj yuav pom tias lub hau npog yog kho los ntawm plaub lub ntsiab lus riveting ntawm lub hauv paus.Ntev npaum li plaub lub ntsiab lus riveting yog xoob lossis cov ntsiab lus riveting yog shrunk los yog deformed tom qab kub kub, lub hau yuav poob.Tsuas yog xyuam xim rau ob qho teeb meem hauv qab no los tiv thaiv lub hau, lub hauv paus siv cov ntaub ntawv kub, ob lub ntsiab lus riveting rau riveting tsau, ua ib txoj hauj lwm zoo ntawm ob qho teeb meem saum toj no, qhov teeb meem no daws tau zoo kawg nkaus.
5. Kev xav ntawm tes: Ntau tus neeg siv khoom tau teb, thiab kev xav ntawm tes ntawm cov qauv xa los ntawm ntau tus neeg muag khoom zoo sib xws, tab sis thaum nws los txog rau ntau lawm, tes kev xav txawv.Qhov tseeb, qhov teeb meem no muaj ntau heev, peb txhua tus paub tias qhov hloov pauv xav tau thiab khawm quab yuam yog tswj los ntawm shrapnel.Peb feem ntau hais tias shrapnel muab faib ua phosphorus tooj liab shrapnel thiab stainless hlau shrapnel.Tam sim no, ntau manufacturers xaiv phosphorus tooj liab shrapnel thiaj li yuav txuag tau nqi.Phosphorus tooj liab shrapnel yog tus nqi-zoo, uas kuj yog vim li cas rau siv dav.Tab sis phosphor tooj liab shrapnel tom qab lub cub tawg kub yuav tsim transformation, shrinkage yog loj, yog li ua rau tsis zoo txhais tes.
Kev siv stainless hlau shrapnel yuav tsis muaj qhov teeb meem no, tab sis tus nqi ntawm stainless hlau shrapnel yog tus nqi siab, uas ua rau ntau manufacturers xaiv qhov kev pheej hmoo ntawm phosphorus tooj liab shrapnel, yog li nyob rau hauv kev yuav khoom ntawm TACT hloov 6 × 6 yuav tsum nug meej cov lus nug. .
Rau, lub teeb xovxwm tsis conductive: ntau tus neeg siv khoom, nyob rau hauv kev siv cov khoom feem ntau pom tias lub khawm xovxwm tsis teb, yuav nyuaj rau nias, cov khoom muaj cov lus teb ua haujlwm.Vim tias peb cov keyboards raug rau huab cua, ntau cov khoom tiav tsis raug kaw, thiab cov neeg siv khoom siv hluav taws xob xav tau cua sov dissipation.Nyob rau hauv cov huab cua ntub, qhov hloov shrapnel yog ib qho yooj yim rau oxidized, kev sib cuag kev ua tau zoo tom qab oxidation tsis zoo li ua ntej, uas yog, muaj ib lub teeb xovxwm tsis conductive teeb meem.
Thaum peb tshem tawm qhov hloov pauv, peb pom tias muaj qhov me me dub ntawm lub shrapnel, thiab qhov me me dub no yog cov nyhuv ntawm oxidation ntawm shrapnel.Yog li, nws raug pom zoo tias cov khoom siv hluav taws xob uas peb tsis siv nyob rau lub sijhawm zoo tib yam yuav tsum muab tso rau hauv qhov chaw qhuav, thiab cov khoom siv hluav taws xob them ua ntej yuav tsum tau oxidized.
