Hauv cov txheej txheem ntawm kev kawm hluav taws xob, peb feem ntau paub txog cov ntawv luam tawm Circuit Board (PCB) thiab kev sib koom ua ke (IC), ntau tus neeg "tsis meej pem" txog ob lub ntsiab lus no. Qhov tseeb, lawv tsis yog qhov nyuaj, hnub no peb yuav qhia meej qhov txawv ntawm PCB thiab kev sib koom ua ke.
PCB yog dab tsi?
Printed Circuit Board, tseem hu ua Printed Circuit Board hauv Suav, yog ib qho tseem ceeb hauv hluav taws xob, lub cev kev txhawb nqa ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob. Vim nws yog tsim los ntawm hluav taws xob luam ntawv, nws yog hu ua "printed" Circuit Court board.
Lub rooj tsav xwm tam sim no, feem ntau yog tsim los ntawm cov kab thiab Nto (Cov Qauv), Dielectric txheej (Dielectric), lub qhov (Los ntawm lub qhov / ntawm), tiv thaiv vuam number case (Solder resistant / Solder Mask), tshuaj ntsuam luam ntawv (Legend / Marking / Silk screen ), Kev kho deg, Nto tiav), thiab lwm yam.
Qhov zoo ntawm PCB: siab ceev, kev ntseeg siab, tsim qauv, tsim tau, kuaj tau, sib dhos, ruaj khov.
Dab tsi yog ib qho kev sib xyaw ua ke?
Ib qho kev sib xyaw ua ke yog ib qho khoom siv hluav taws xob me me lossis ib feem. Siv cov txheej txheem tshwj xeeb, cov khoom sib txuas thiab kev sib txuas xws li transistors, resistors, capacitors thiab inductors xav tau nyob rau hauv ib lub voj voog yog tsim los ntawm ib qho me me los yog ob peb daim me me ntawm cov semiconductor nti lossis dielectric substrate thiab tom qab ntawd muab ntim rau hauv lub plhaub kom dhau los ua microstructure. nrog rau kev ua haujlwm hauv Circuit Court. Tag nrho cov khoom sib xyaw ua ke, ua rau cov khoom siv hluav taws xob ua ib kauj ruam loj ntawm kev siv hluav taws xob tsawg, kev siv hluav taws xob tsawg, kev txawj ntse, thiab kev ntseeg siab. Nws yog sawv cev los ntawm tsab ntawv "IC" hauv Circuit Court.
Raws li kev ua haujlwm thiab cov qauv ntawm kev sib xyaw ua ke, nws tuaj yeem muab faib ua analog integrated circuits, digital integrated circuit thiab digital / analog sib xyaw ua ke.
Integrated Circuit Court muaj qhov zoo ntawm qhov me me, lub teeb yuag, tsis tshua muaj hlau lead, thiab vuam taw tes, lub neej ntev, kev ntseeg siab, kev ua haujlwm zoo, thiab lwm yam.
Kev sib raug zoo ntawm PCB thiab integrated circuit.
Kev sib xyaw ua ke feem ntau yog hu ua chip kev sib koom ua ke, zoo li cov niam ntawv ntawm lub qaum qaum teb, CPU sab hauv, hu ua kev sib koom ua ke, lub npe qub tseem hu ua integrated block. Thiab PCB yog lub rooj tsav xwm Circuit Court peb feem ntau paub nws thiab luam tawm ntawm lub rooj tsav xwm Circuit Court welding chips.
Ib qho kev sib xyaw ua ke (IC) yog welded rau PCB board. PCB board yog tus cab kuj ntawm ib qho kev sib koom ua ke (IC).
Hauv cov ntsiab lus yooj yim, ib qho kev sib xyaw ua ke yog ib qho kev sib txuas ua ke rau hauv ib lub nti, uas yog tag nrho. Thaum nws puas lawm sab hauv, lub nti yuav puas. PCB tuaj yeem vuam cov khoom ntawm nws tus kheej, thiab cov khoom tuaj yeem hloov tau yog tias tawg.
