Dab tsi yog ib qho cam pob qhov tsis xws luag?
Ib lub pob nyem yog ib qho ntawm cov kev tiv thaiv feem ntau tshwm sim thaum ua ntawv thov cov rooj tsav tsheb nplaim hluav taws xob. Muaj tseeb rau lawv lub npe, lawv yog ib pob ntawm solder uas tau sib cais los ntawm lub cev tseem ceeb uas ua rau cov sib koom ua ke ntawm cov rooj sib tham rau hauv pawg thawj coj.
Cov khoom siv ntiv tes yog cov khoom siv customer, cov ntsiab lus uas yog tias lawv tuaj yeem ua rau hluav taws xob luam tawm, lawv tuaj yeem cuam tshuam rau kev ntseeg tau ntawm cov ntawv luam tawm hluav taws xob.
IbIPC-A-610, tus PCB uas muaj ntau dua 5 quav khoom (<= 0.13mm) tsis pub dhau 6003mm) tsis pub dhau 6003mm ua txhaum qhov tsawg tshaj plaws clearance clearance. Txawm li cas los xij, txawm hais tias cov cai no lub xeev tias cov pob uas cam tuaj yeem sab laug yog tias lawv tau daig ntawm kev nyab xeeb, tsis muaj txoj kev paub tseeb yog tias lawv yog.
Yuav ua li cas kom tau cov khoom sib dhos ua ntej tshwm sim
Cov khoom sib dhos tuaj yeem tshwm sim los ntawm ntau yam, ua kev kuaj mob ntawm qhov teeb meem me ntsis nyuaj. Muaj qee kis, lawv tuaj yeem ua tiav. Ntawm no yog ob peb ntawm cov laj thawj ua teb cov laj thawj Colder Pob hauv PCB los ua ke txheej txheem.
Kev vaum-Dejtau nce zuj zus los ua ib qho ntawm cov teeb meem loj tshaj plaws rau luam tawm Circuit Court board manufacturers niaj hnub no. Ib cag ntawm cov khoom siv hluav taws kub thiab cov me me tawg, nws kuj tuaj yeem ua rau cov khoom siv sib zog los ua cov huab cua khiav tawm lossis dej. Xyuas kom meej tias cov ntawv luam tawm hluav taws xob tau qhuav kom zoo ua ntej daim ntawv thov kev siv tshuaj, lossis hloov kho kom tswj cov av noo hauv kev tsim khoom.
Solder Muab Tshuaj Txhuam- Cov teeb meem hauv cov ham muab tshuaj txhuam nws tus kheej tuaj yeem pab txhawb rau kev tsim tawm ntawm kev ua si sib tsoo. Yog li, nws tsis tau qhia kom rov siv cov muab tshuaj txhuam lossis tso cai rau cov kev siv ntawm cov tshuaj txhuam cev yav dhau los nws hnub tas sij hawm. SOLDER muab tshuaj yuav tsum tau muab khaws cia kom zoo thiab ua kom raws li cov txheej txheem ntawm cov chaw tsim khoom. Dej Soluble ham muab tshuaj txhuam kuj tseem tuaj yeem pab txhawb kom noo noo ntau.
Stencil tsim- SOLDER BROODING tuaj yeem tshwm sim thaum ib tus stencil tau raug ntxuav tsis raug, lossis thaum tus stencil tau raug tsis raug cai. Yog li, ntseeg ibKev paub luam tawm cov board fabriccuiticThiab Rooj Sib Tham Lub Tsev tuaj yeem pab koj kom tsis txhob ua yuam kev no.
Refow Cov Ntsuas Kub- FLEY SYMVENT xav kom yaj ntawm tus nqi raug. Ibsiab ramp-uplossis tus nqi ua ntej ua ntej yuav ua rau muaj kev tsim tawm ntawm kev ua haujlwm sib tsoo. Txhawm rau daws qhov no, ua kom koj lub ramp-up yog tsawg dua 1.5 ° C / sec los ntawm chav nruab nrab chav rau 150 ° C.
Tolder Pob Tshem Tawm
Txau hauv cov tshuab cua tshuabyog txoj kev zoo tshaj plaws rau kev tshem tawm pob pob tsis huv. Cov tshuab no siv cov cua tshuab siab hlau hluav taws xob uas tau yuam kev cov pob zeb tawm los ntawm cov chaw luam tawm ua tsaug ua tsaug rau lawv cov kev cuam tshuam siab.
Txawm li cas los xij, hom kev tshem tawm no tsis zoo thaum lub hauv paus ua rau cov txiv ntoo tsis raug cai thiab ua kom muaj kev tiv thaiv cov teeb meem ua ntej muab cov teeb meem.
Raws li qhov tshwm sim, nws yog qhov zoo tshaj plaws los kuaj qhov ua rau pob zeb ua kom ntxov li sai tau, raws li cov txheej txheem no tuaj yeem cuam tshuam koj cov pcb tsim thiab ntau lawm. Kev tiv thaiv muaj qhov txiaj ntsig zoo tshaj plaws.
Hla qhov tsis xws luag nrog Inc
Thaum muaj kev xav, peb nkag siab tias kev paub yog txoj kev zoo tshaj plaws kom tsis txhob hiccups uas los nrog pcb fabrication thiab kev sib txoos. Peb muab qhov zoo tshaj plaws-hauv-chav ua haujlwm zoo tau ntseeg hauv cov tub rog thiab cov ntawv thov Aerospace, thiab muab cov tshuaj tiv thaiv thiab ntau lawm.
