Kev Paub Ntawm Ib Pawg Sab Tom Qab
Jun 12, 2017

Dab Tsi yog Ib Pawg Neeg Sab Nrauv. Ib pawg khib nyiab yog ib lub rooj sib tham ib zaug xwb, nws yog siv ntau yam khoom hauv tshuab hluav taws xob sib txuas ua ke, cov khoom siv hluav taws xob yog ib qho tseem ceeb ntawm kev khiav lag luam. Nws qhov tseem ceeb yog sib npaug rau lub hauv paus ntawm lub tsev hais txog, tsuas yog nrog kev ua tau zoo ntawm ib Pawg Neeg Sab Ib Sab, yuav raug tsim ntawm no hauv cov hauv paus khoom zoo. Me me rau xov tooj cua mus rau LCD TV sab hauv cov qauv yuav pom nws cov duab ntxoov ntxoo. Rau cov phooj ywg uas tsis yog-kev paub, nws tsis nkag siab txog cov khoom siv rau ib leeg. Tsis txhob txhawj, hnub no kuv yuav qhia koj universal txog txoj kev paub ntawm Pawg Neeg Sab Ib Sab, nrog rau cov khoom siv ib ntu thiab nws cov yeeb yam.

Tib Tog Neeg Hnub Nyoog

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, cov Japanese Circuit Board pawg tuam txhab lag luam, kev lag luam ntawm ib lub vaj huam sib luag tsim tawm sai sai. Nyob rau hauv cov khoom, thaum ntxov rau cov ntaub ntawv raws li phenolic copper ntawv nyiaj raws li, tab sis vim yog cov khoom thaum lub sij hawm ntawm hluav taws xob rwb thaiv tsev tsis muaj, tsis kub tsis kam siv vuam, sib ntswg thiab lwm yam, tom qab lwm daim ntawv nplhaib ream, iav epoxy re thiab lwm yam ntaub ntawv Kev txhim kho, kev siv cov khoom siv hluav taws xob uas yuav tsum muaj rau Ib Pawg Neeg Sab Nraud, yuav luag siv ntawv ntawv phenolic substrate board.

Tib Sab Laj Xwm

Lub Rooj Sab Laj Ib Sab ntawm tus PCB yooj yim tshaj plaws, cov khoom siv 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 uas tau hu ua thiab ib leeg-ib tog. 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;

Ib qho ntawm ib daim duab thaiv kab hlau txuas rau network printing (Vijtsam Printing), uas yog, luam tawm ntawm qhov chaw xaim ntawm tus neeg ua haujlwm tsis kam, tom qab lub sijhawm thiab tom qab ntawd tiv thaiv kab kos rau ntawm lub cim, thiab thaum kawg punching ua tiav qhov chaw qhia qhov thiab qhov zoo . Tsis tas li ntawd, ib qho tsawg ntawm ntau ntau hom khoom, kev siv photoresist tsim ib tug qauv ntawm photography.

Cov khoom siv sab nraud tib

Lub rooj sib tham ib zaug xwb yog pib thaum xyoo 1950 los ntawm kev pib ntawm transistors, Tebchaws Asmeskas uas yog qhov chaw ntawm cov khoom tsim, thaum txoj kev tsim ntau yam los siv cov qauv khib nyiab coj los siv rau txoj kev kawm. 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, cov Japanese Circuit Board pawg tuam txhab lag luam, kev lag luam ntawm ib lub vaj huam sib luag tsim tawm sai sai. Nyob rau hauv cov khoom, thaum ntxov rau cov ntaub ntawv raws li phenolic copper ntawv nyiaj raws li, tab sis vim yog cov khoom thaum lub sij hawm ntawm hluav taws xob rwb thaiv tsev tsis muaj, tsis kub tsis kam siv vuam, sib ntswg thiab lwm yam, tom qab lwm daim ntawv nplhaib ream, iav epoxy re thiab lwm yam ntaub ntawv Kev txhim kho, kev siv cov khoom siv hluav taws xob uas yuav tsum muaj rau Ib Pawg Neeg Sab Nraud, yuav luag siv ntawv ntawv phenolic substrate board.
