Lub rooj sib dhos ceev yog qhov siab, cov khoom siv hluav taws xob me me thiab lub teeb hauv cov khoom hnyav tsuas yog hais txog 1/10 ntawm cov tsoos plug-inctration

Tom qab kev xaiv dav dav ntawm SMT, qhov ntim ntawm cov khoom siv hluav taws xob raug txo los ntawm 40% mus rau 60%, thiab qhov hnyav yog txo los ntawm 60% mus rau 80%.

Kev ntseeg siab thiab muaj zog vibration kuj.Tsawg defect tus nqi ntawm solder joint.

Cov yam ntxwv zoo siab zaus.Txo electromagnetic thiab RF cuam tshuam.

Yooj yim kom ua tiav automation, txhim kho kev tsim khoom.Txo tus nqi los ntawm 30% ~ 50%.Txuag cov ntaub ntawv, lub zog, khoom siv, neeg ua haujlwm, sijhawm, thiab lwm yam.

Vim li cas thiaj siv Surface Mount Skills (SMT)?

Cov khoom siv hluav taws xob nrhiav miniaturization, thiab cov perforated plug-in Cheebtsam uas tau siv lawm yuav tsis raug txo.

Kev ua haujlwm ntawm cov khoom siv hluav taws xob tau ua tiav ntau dua, thiab cov khoom siv sib xyaw ua ke (IC) xaiv tsis muaj cov khoom siv perforated, tshwj xeeb tshaj yog cov nplai loj, cov ics sib xyaw ua ke, thiab cov khoom sib xyaw ua ke yuav tsum tau xaiv.

Cov khoom loj, ntau lawm automation, lub Hoobkas kom qis tus nqi siab tso zis, tsim cov khoom zoo kom tau raws li cov neeg siv khoom xav tau thiab ntxiv dag zog rau kev lag luam kev sib tw

Kev txhim kho ntawm cov khoom siv hluav taws xob, kev txhim kho ntawm kev sib xyaw ua ke (ics), kev siv ntau yam ntawm cov ntaub ntawv semiconductor

Kev hloov pauv hluav taws xob thev naus laus zis yog qhov tseem ceeb, chasing lub ntiaj teb sib txawv

Vim li cas thiaj siv cov txheej txheem tsis huv hauv qhov kev txawj ntse saum npoo av?

Hauv cov txheej txheem tsim khoom, cov dej khib nyiab tom qab cov khoom tu coj cov dej tsis zoo, lub ntiaj teb thiab tsiaj txhu thiab cov nroj tsuag.

Ntxiv nrog rau kev ntxuav dej, siv cov kuab tshuaj organic uas muaj chlorofluorocarbons (CFC & HCFC) Kev ntxuav kuj ua rau muaj kuab paug thiab puas tsuaj rau huab cua thiab huab cua.Cov residue ntawm tu tus neeg saib xyuas yuav ua rau corrosion ntawm lub tshuab board thiab cuam tshuam rau qhov zoo ntawm cov khoom.

Txo cov kev ua haujlwm tu thiab cov nqi kho tshuab.

Tsis muaj kev ntxuav tuaj yeem txo qhov kev puas tsuaj los ntawm PCBA thaum lub sijhawm txav thiab tu.Tseem muaj qee yam khoom uas tsis tuaj yeem ntxuav tau.

Cov flux residue tswj tau thiab tuaj yeem siv tau raws li cov khoom xav tau los tiv thaiv qhov muag pom ntawm kev ntxuav.

Cov dej ntws seem tau raug txhim kho tas li rau nws txoj haujlwm hluav taws xob los tiv thaiv cov khoom tiav los ntawm cov hluav taws xob xau, ua rau muaj kev raug mob.

Dab tsi yog SMT thaj nrhiav kom tau txoj hauv kev ntawm SMT thaj ua cov nroj tsuag?

Kev kuaj xyuas hauv SMT ua haujlwm yog ib qho tseem ceeb heev los xyuas kom meej qhov zoo ntawm PCBA, cov txheej txheem tseem ceeb ntawm kev tshawb pom muaj xws li phau ntawv pom kev pom, solder paste thickness gauge nrhiav kom tau, tsis siv neeg kho qhov muag, kuaj X-ray, kuaj online, xeem rab koob, thiab lwm yam. vim qhov sib txawv ntawm kev tshawb nrhiav cov ntsiab lus thiab cov yam ntxwv ntawm txhua tus txheej txheem, cov txheej txheem tshawb nrhiav siv hauv txhua txoj kev kuj txawv.Nyob rau hauv txoj kev tshawb pom ntawm smt thaj ua cov nroj tsuag, phau ntawv pom kev pom thiab kev tshuaj xyuas tsis siv neeg Optical thiab X-ray tshuaj xyuas yog peb txoj hauv kev siv ntau tshaj plaws hauv kev soj ntsuam cov txheej txheem saum npoo.Kev sim online tuaj yeem yog ob qho kev sim zoo li qub thiab kev sim dynamic.

Ntiaj teb no Wei Technology muab koj cov lus qhia luv luv rau qee txoj kev tshawb pom:

Ua ntej, phau ntawv qhia kev pom kev pom.

Txoj kev no muaj cov tswv yim tsawg dua thiab tsis tas yuav tsim cov kev sim ntsuas, tab sis nws qeeb thiab cov ntsiab lus thiab xav tau kev pom qhov muag ntsuas qhov ntsuas.Vim tsis muaj kev tshuaj xyuas qhov muag, nws tsis tshua muaj siv los ua qhov tseem ceeb ntawm kev tshuaj ntsuam xyuas qhov zoo ntawm SMT tam sim no, thiab feem ntau nws yog siv rau rework thiab lwm yam.

Thib ob, optical detection method.

Nrog kev txo qis ntawm PCBA nti pob qhov loj me thiab qhov nce ntawm Circuit Court board thaj ceev, SMA kev tshuaj xyuas tau dhau los ua nyuaj, kev tshuaj xyuas qhov muag tsis muaj zog, nws qhov kev ruaj ntseg thiab kev ntseeg siab yog qhov nyuaj rau kev ua kom tau raws li qhov xav tau ntawm kev tsim khoom thiab kev tswj kom zoo, yog li kev siv cov kev tshawb nrhiav dynamic tau dhau los ua qhov tseem ceeb.

Siv automated optical inspection (AO1) ua ib qho cuab yeej los txo qhov tsis xws luag.

Nws tuaj yeem siv los nrhiav thiab tshem tawm qhov yuam kev thaum ntxov hauv cov txheej txheem kev ua haujlwm kom ua tiav cov txheej txheem tswj tau zoo.AOI siv cov tshuab tsis pom kev zoo, cov txheej txheem tshiab lub teeb pub, kev nthuav dav dav thiab cov txheej txheem ua haujlwm nyuaj kom ua tiav qhov tsis xws luag ntes tus nqi ntawm kev ntsuas siab.

AOl txoj haujlwm ntawm SMT cov kab ntau lawm.Feem ntau muaj 3 hom AOI cov cuab yeej ntawm SMT cov kab ntau lawm, thawj zaug yog AOI uas tau muab tso rau ntawm lub vijtsam luam ntawv txhawm rau txheeb xyuas qhov ua txhaum ntawm cov tshuaj nplaum, uas yog hu ua post-screen printing AOl.

Qhov thib ob yog AOI uas tau muab tso rau tom qab thaj chaw txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws yog AOI.

Hom thib peb ntawm AOI yog muab tso rau tom qab reflow los kuaj xyuas cov cuab yeej txuas thiab vuam faults tib lub sijhawm, hu ua post-reflow AOI.
