Tib Sab Lom Zem Thiab Ob Tog Tuaj Rau Cov Rooj Vaj Huam Sib Luag Distinction
Jun 23, 2017

Lub Cheeb Tsam Xub Thawj Xwb:

Lub rooj sib tham ib zaug xwb yog pib thaum xyoo 1950 los ntawm kev pib ntawm transistor, Tebchaws Meskas raws li qhov chaw tsim cov khoom, thaum lub tswv yim tseem ceeb rau cov khib nyiab khib nyiab ua rau txoj kev sib luag. Xyoo 1953 ~ 1955, Nyiv tuaj rau tooj liab cov ntawv rau thawj zaug ua ntawm daim ntawv phenolic tooj liab ntawv substrate, thiab coob tus siv hauv xov tooj cua. Nyob rau hauv 1956, lub Japanese Circuit Court Board cov kws lag luam, Tib Sab Liab tsim technology tam sim ntawd ceev nrooj. Nyob rau hauv cov khoom, thaum ntxov raws li ntawv raws li fenolic tooj liab ntawv nyiaj, tab sis vim lub phenolic khoom hluav taws xob rwb thaiv kom tsis muaj, tsis kub tsis kam vuam, sib ntswg thiab lwm yam, tom qab lwm daim ntawv ci ci, iav fiber epoxy resin kev loj hlob , tam sim no noj ntawm cov khoom siv hluav taws xob uas yuav tsum muaj rau Ib Pawg Neeg Sab Muag, yuav luag siv ntawv ntawv phenolic substrate board.

Tsav Tus Sab Nraud Sab Nraud:

Lub Rooj Sab Laj Ib Sab Ib Leeg nyob rau ntawm cov PCB yooj yim tshaj plaws, cov khoom ntim ntawm ib sab, cov xov hlau muaj concentrated rau sab nraud. Vim tias cov xov hlau tsuas tshwm ntawm ib sab, peb hu ua hom PCB no hu ua single-sided. Vim tias muaj ntau txoj cai txwv tsis pub hnyav rau qhov tsim ntawm pawg neeg sib sab laj (vim tias tsuas muaj ib sab xwb, qhov thaiv tsis hla thiab yuav tsum nyob ib ncig ntawm txoj kev), yog li tsuas yog lub sij hawm thaum siv lub rooj sib tham;

Tsuas yog cov kab sib txuas ntawm cov kab sib txuas ua haujlwm rau Network printing (ScreennPrinting), uas yog, lub npoo npooj luam tawm ntawm cov neeg ua haujlwm tsis sib haum, tom qab etching thiab ces mus rau ntawm cov neeg ua haujlwm ntawm cov pov thawj, thiab thaum kawg xuas tes ua tiav qhov chaw ntawm lub qhov thiab cov duab Lub Tshaj Tawm, muaj tsawg tsawg ntawm ntau ntau hom khoom, kev siv photoresist los tsim ib qho qauv ntawm kev thaij duab

Ob Taws Ob Tog (Ob Sab Teev) rau ob sab ntawm lub thaiv. Tab sis, siv ob tog ntawm cov hlau, yuav tsum yog nruab nrab ntawm ob tog muaj qhov kev sib txuas lus txuas rau Caixing. Tus "choj" ntawm qhov kev sib txuas li no hu ua ntawm. Qhov chaw qhia yog nyob rau ntawm PCB, muaj puv lossis coated nrog hlau qhov, nws tuaj yeem txuas nrog ob sab ntawm cov hlau. Vim tias ob npaug ntawm lub voj voog yog ob zaug loj loj li ib cov khib nyiab, thiab vim cabling tau stagered (tuaj yeem mus rau sab nraud), nws yog qhov tsim nyog rau kev siv ntau tshaj li Ib Sab Sab Hauv Ib Pawg.

Cov nram qab no yog tib yam li "

Nws yog ib qho tseem ceeb hauv pawg thawj coj saib xyuas PCB, nws siv zoo heev, kom pom pawg PCB Board tsis yog ib qho yooj yim heev, Kuv ntseeg tias cov phooj ywg nyob rau kev nkag siab ntawm ib Pawg Neeg Sab Nraud yog tag Ntsuas lub vaj huam sib luag ob sab yog qhov txuas ntxiv ntawm Ib Pawg Neeg Sab Ib Sab, lub ntsiab lus hais tias ib txoj kab sib tw nkaus xwb tsis txaus mus rau sab nraum qab, muaj cov tseem ceeb ntawm ob lub phom thaiv uas muaj kev sib tw. Ib qho yooj yim taw tes yog ob kab sib dhos, ob tog muaj ib txoj kab! Lub siab dav yog: kev sib tw ob tog tib si yog ob lub rooj tsav khoom! Qee tus phooj ywg yuav nug, piv txwv li, pawg thawj coj ntawm ob tog sib txuas, tab sis tsuas yog ib sab ntawm cov khoom siv hluav taws xob, xws li lub rooj zaum kawg yog lub vaj huam sib luag lossis ib Pawg Neeg Ib Sab? Cov lus teb yog pom zoo, lub rooj tsav xwm no yog ib lub vaj huam sib luag rau ob qho, tab sis tsuas yog nyob hauv ob lub phaj ntawm lub phaj tuaj rau ntawm qhov chaw xwb.
