Kab lus no muab cov lus qhia ntxaws ntxaws rau PCB Circuit Board baking txheej txheem thiab cov lus pom zoo kom txuag hluav taws xob.Nrog rau qhov teeb meem loj zuj zus thoob ntiaj teb hluav taws xob thiab kev ntxiv dag zog ntawm ib puag ncig cov cai, PCB cov tuam txhab tau muab cov kev xav tau siab dua rau cov khoom siv txuag hluav taws xob.Ci yog txheej txheem tseem ceeb hauv cov txheej txheem tsim khoom PCB.Cov ntawv thov nquag siv hluav taws xob ntau.Yog li ntawd, kev txhim kho cov khoom siv ci los txhim kho kev txuag hluav taws xob tau dhau los ua ib txoj hauv kev rau PCB board manufacturers kom txuag hluav taws xob thiab txo cov nqi.
Cov txheej txheem ci yuav luag khiav los ntawm tag nrho cov txheej txheem ntawm PCB Circuit board ntau lawm.Cov hauv qab no yuav qhia koj txog cov txheej txheem ci uas yuav tsum tau ua rau PCB Circuit board ntau lawm.
1. Cov txheej txheem txheej txheem yuav tsum tau ua rau ci PBC boards
1. Lamination, raug, thiab browning nyob rau hauv zus tau tej cov txheej txheej panels yuav tsum tau nkag mus rau hauv lub qhuav chav tsev rau ci.
2. Lub hom phiaj, edging thiab sib tsoo tom qab lamination yuav tsum tau tshem tawm cov dej noo, hnyav thiab kev ntxhov siab sab hauv, ua kom cov qauv ruaj khov thiab txhim khu adhesion, thiab yuav tsum tau ua kev kho mob ci.
3. Thawj tooj liab tom qab drilling yuav tsum tau ci los txhawb kev ruaj ntseg ntawm cov txheej txheem electroplating.
4. Kev kho ua ntej, lamination, raug thiab kev loj hlob nyob rau hauv txheej txheej txheej tag nrho yuav tsum tau ci kub los tsav cov tshuaj tiv thaiv los txhim kho cov ntaub ntawv kev ua tau zoo thiab kev cuam tshuam.
5. Printing, pre-baking, raug, thiab kev loj hlob ua ntej solder daim npog qhov ncauj yuav tsum tau ci los xyuas kom meej stability thiab adhesion ntawm solder daim npog qhov ncauj.
6. Pickling thiab luam ntawv ua ntej luam ntawv yuav tsum tau ci los txhawb cov tshuaj tiv thaiv thiab cov khoom ruaj khov.
7. Ci tom qab kev kho deg ntawm OSP yog qhov tseem ceeb rau kev ruaj ntseg thiab adhesion ntawm OSP cov ntaub ntawv.
8. Nws yuav tsum tau ci ua ntej molding los xyuas kom meej lub dryness ntawm cov khoom, txhim kho cov adhesion nrog lwm yam ntaub ntawv, thiab xyuas kom meej cov molding nyhuv.
9. Ua ntej qhov kev sojntsuam ya ya, txhawm rau kom tsis txhob muaj qhov tsis zoo thiab kev txiav txim siab tsis zoo los ntawm kev cuam tshuam ntawm cov dej noo, kev ua haujlwm ci kuj yuav tsum tau ua.
10. Kev kho mob ci ua ntej FQC tshuaj xyuas yog tiv thaiv kom tsis txhob ya raws ntawm qhov chaw lossis sab hauv PCB lub rooj tsavxwm los ntawm kev ua qhov kev ntsuam xyuas tsis raug.
2. Cov txheej txheem ci feem ntau muab faib ua ob theem: qhov kub-kub ci thiab qis-kub ci:
1. Kev kub-kub kub yog feem ntau tswj ntawm ib ncig ntawm 110°C, thiab lub sijhawm ntev yog li 1.5-4 teev;
2. Tsawg-kub ci kub yog feem ntau tswj ntawm ib ncig ntawm 70°C, thiab lub sijhawm ntev li 3-16 teev.
3. Thaum lub sij hawm PCB Circuit Board board ci txheej txheem, cov khoom siv ci hauv qab no yuav tsum tau siv:
Ntsug, txuag hluav taws xob qhov cub, tag nrho tsis siv neeg lub voj voog nqa ci cov kab ntau lawm, infrared qhov cub thiab lwm yam khoom siv hluav taws xob PCB luam tawm.
Cov khoom sib txawv ntawm PCB qhov cub yog siv rau cov kev xav tau sib txawv, xws li: PCB board qhov plugging, solder mask screen printing baking, uas yuav tsum muaj cov haujlwm loj loj.Kev txuag hluav taws xob qhov cub qhov cub feem ntau yog siv los txuag ntau tus neeg ua haujlwm thiab cov khoom siv thaum ua tiav kev ua haujlwm siab.Kev ua haujlwm zoo ci, kev ua haujlwm siab thermal thiab kev siv hluav taws xob, kev lag luam thiab ib puag ncig tus phooj ywg, yog siv dav hauv kev lag luam hauv Circuit Court board rau solder mask pre-baking thiab text post-baking of PCB boards;Thib ob, nws yog siv ntau dua rau ci thiab ziab ntawm PCB board ya raws thiab kev ntxhov siab sab hauv.Nws yog ntsug cua kub ncig qhov cub nrog cov khoom siv qis dua, hneev taw me me thiab tsim nyog rau ntau txheej hloov tau yooj yim ci.
4. PCB Circuit board ci kev daws teeb meem, cov khoom siv qhov cub pom zoo:
Raws li cov ntsiab lus, nws yog ib qho kev hloov tsis tau uas PCB Circuit Board tuam ntxhab muaj ntau dua thiab siab dua rau cov khoom siv txuag hluav taws xob.Nws yog ib qho tseem ceeb heev rau kev txhim kho qib txuag hluav taws xob, txuag cov nqi thiab txhim kho kev tsim khoom los ntawm kev txhim kho lossis hloov cov txheej txheem ci khoom.Kev txuag hluav taws xob qhov cub qhov cub muaj qhov zoo ntawm kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev ua haujlwm siab, thiab tam sim no tau siv dav.Qhov thib ob, cov cua kub cua kub muaj qhov zoo tshwj xeeb hauv high-end PCB boards uas xav tau kev ua haujlwm siab thiab ua kom huv si xws li IC carrier boards.Tsis tas li ntawd, lawv kuj muaj infrared rays.Qhov cub thiab lwm yam khoom siv qhov cub yog tam sim no paub tab kom qhuav thiab kho cov kev daws teeb meem.
Raws li tus thawj coj hauv kev txuag hluav taws xob, Xinjinhui txuas ntxiv txhim kho thiab ua kom muaj kev hloov pauv hloov pauv.Hauv xyoo 2013, lub tuam txhab tau tsim thawj tiam PCB ntawv tom qab ci qhov-hom tshuaj ntsuam luam ntawv qhov cub qhov cub, uas txhim kho kev txuag hluav taws xob los ntawm 20% piv nrog cov khoom siv niaj hnub.Nyob rau hauv 2018, lub tuam txhab tau tshaj tawm lub thib ob tiam PCB ntawv tom qab ci qhov cub, uas ua tiav ib tug leapfrog upgrade ntawm 35% nyob rau hauv lub zog txuag piv rau thawj tiam.Nyob rau hauv 2023, nrog rau kev tshawb fawb thiab kev loj hlob ntawm ib tug xov tooj ntawm invention patents thiab tshiab technologies, lub tuam txhab lub zog-txuag theem tau nce mus txog 55% piv nrog rau thawj tiam, thiab tau txais kev pom zoo los ntawm ntau 100 lub tuam txhab saum toj kawg nkaus hauv PCB. kev lag luam, suav nrog Jingwang Electronics.Cov tuam txhab no tau raug caw los ntawm Xin Jinhui tuaj xyuas thiab sib txuas lus nrog lub Hoobkas kuaj vaj huam sib luag.Nyob rau hauv lub neej yav tom ntej, Xinjinhui tseem yuav tshaj tawm cov cuab yeej siv high-tech.Thov sawv daws pab txhawb nqa thiab nawb, thov hu tuaj rau peb tau sib tham thiab teem caij tuaj ntsib peb kom sib tham tim ntsej tim muag.
