Kev soj ntsuam ntawm Yog vim li cas rau Solder Mask Stripping

Ink yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm Circuit Court boards, thiab tus cwj mem tsis zoo kuj yog ib qho laj thawj rau kev tshem tawm ntawm cov roj ntsuab ntawm cov boards. Cia wb mus saib dab tsi yuav tsum tau them sai sai rau thaum siv cov ntawv luam tawm Circuit Board number case?

 

Muaj peb lub laj thawj tseem ceeb rau kev tshem tawm ntawm tus cwj mem ntsuab los ntawm pcb solder mask:

 

1. Thaum luam ntawv number case rau ntawm pcb, kev kho ua ntej tsis ua kom zoo, xws li stains, plua plav, lossis impurities ntawm lub rooj tsavxwm, lossis qee qhov chaw raug oxidized. Qhov tseeb, kev daws qhov teeb meem no yooj yim heev. Tsuas yog ua qhov kev kho ua ntej dua, tab sis siv zog los ntxuav cov stains, impurities, lossis oxide txheej ntawm cov ntawv luam tawm ntawm lub rooj tsavxwm. Qhov no yog vim qhov yuam kev ntawm cov neeg ua haujlwm tsim khoom hauv kev ua haujlwm thiab kev tswj tsis zoo.

 

2. Lub sij hawm ci ntawm lub rooj tsav xwm luam tawm luv luv los yog qhov kub tsis txaus, vim tias cov ntawv luam tawm Circuit Board yuav tsum tau kub kub tom qab luam ntawv tus number case thermosetting. Yog tias qhov kub thiab lub sijhawm ci tsis txaus, nws yuav ua rau lub zog ntawm tus cwj mem ntawm lub rooj tsavxwm tsis txaus. Tom qab cov txheej txheem txuas ntxiv, cov khoom kawg raug xa mus, thiab cov neeg siv khoom tau txais lub rooj tsavxwm rau kev ua SMT. Thaum lub sij hawm SMT ua, qhov kub siab nyob rau hauv lub cub tawg tuaj yeem ua rau tus number case ntawm lub rooj tsavxwm luam tawm poob.

 

3. Cov teeb meem zoo ntawm tus number case, xws li tus number case tas sij hawm lossis kev yuav khoom tsis paub hom number case, kuj tuaj yeem ua rau PCB number case poob thaum dhau los ntawm lub cub tawg. Qee lub tuam txhab me me yuav cov kua nplaum uas tsis tau siv ntev, thiab muaj qhov sib txawv ntawm cov xim thiab kev ua tau zoo tom qab siv ntau yam, ua rau nws yooj yim dua rau tus number case poob.

 

Kuv yuav tsum ceev faj dab tsi thaum siv tus cwj mem? Hauv kev lag luam pcb, cov tuam ntxhab feem ntau muaj kev paub txog kev siv tus cwj mem thiab yuav tsum xa mus rau cov kev cai cuam tshuam thaum siv tus cwj mem:

 

Daim duab: Full -auto exposure

 

1. Kev ntsuas kub: Txawm li cas los xij, qhov kub ntawm tus number case yuav tsum tau khaws cia hauv qab 20-25 degree , thiab qhov kub hloov pauv yuav tsum tsis txhob loj dhau, txwv tsis pub nws yuav cuam tshuam rau viscosity ntawm tus number case thiab qhov zoo thiab ua haujlwm ntawm kev tshuaj ntsuam luam ntawv. Tshwj xeeb tshaj yog thaum tus number case khaws cia sab nraum zoov lossis ntawm qhov kub sib txawv, nws yuav tsum muab tso rau ntawm qhov kub thiab txias rau ob peb hnub ua ntej rov siv dua lossis kom txog thaum tus number case chim mus txog qhov tsim nyog ua haujlwm kub. Qhov no yog vim tias siv tus cwj mem txias tuaj yeem ua rau kev tshuaj ntsuam luam ntawv ua haujlwm tsis zoo thiab ua rau muaj teeb meem tsis tsim nyog. Yog li ntawd, txhawm rau tswj qhov zoo ntawm tus number case, nws yog qhov zoo tshaj los khaws nws nyob rau hauv ib txwm kub txheej txheem txheej txheem.

 

2. Ua ntej siv, tus number case yuav tsum tau ua kom zoo thiab ua tib zoo sib xyaw manually lossis mechanically. Yog tias huab cua nkag mus rau hauv tus cwj mem, nws yuav tsum tau tso tseg kom sawv ntsug rau lub sijhawm ua ntej siv. Yog tias yuav tsum tau dilution, ua ntej sib tov kom huv si thiab tom qab ntawd sim nws cov viscosity. Lub thoob dej yuav tsum tau muab kaw tam sim tom qab siv. Nyob rau tib lub sijhawm, tsis txhob muab tus cwj mem rau ntawm qhov screen rov qab rau hauv lub thoob dej thiab sib tov nrog tus cwj mem tsis siv.

 

3. Nws yuav tsum tau nruab nrog tus neeg saib xyuas tshwj xeeb tsim los ntxuav tus number case, thiab nws yuav tsum tau ua kom huv thiab huv. Tsis muaj teeb meem dab tsi ntawm tus cwj mem nws yog, nws yuav tsum tau ntxuav hauv ib qho mus, nyiam dua siv cov kuab tshuaj huv, thiaj li tsis cuam tshuam rau kev siv lwm cov xim ntawm tus number case.

 

4. Thaum ziab tus number case, nws yuav tsum tau ua nyob rau hauv ib tug ntaus ntawv nrog ib tug zoo pa system kom paub meej tias qhov zoo ntawm tus number case tsis hloov loj.

 

Nyob rau hauv cov txheej txheem luam ntawv tiag tiag, nws yog ib qho tsim nyog yuav tsum tau ua haujlwm raws li tus qauv thiab tswj xyuas cov kev ua haujlwm uas ua tau raws li cov kev cai ntawm cov txheej txheem rau kev tshuaj ntsuam luam ntawv.
