11. Muaj kev paub txog

Yuav ua li cas yog lub motherboard (board) tsim?

PCB manufacturing txheej txheem los ntawm iav epoxy (GlassEpoxy) los yog PCB "substrate" ua los ntawm cov ntaub ntawv zoo sib xws pib. Thawj kauj ruam hauv

kev tsim khoom yog los ua kom pom kev sib txuas ntawm qhov chaw, siv kev hloov pauv tsis zoo (Subtractive)

 

Txoj kev hloov pauv "prints" cov ntawv luam tawm ntawm lub rooj tsav xwm luam tawm mus rau tus neeg xyuas pib hlau.

 

Qhov ua kom yuam kev yog nteg ib txheej nyias ntawm tooj liab rau tag nrho saum npoo thiab tshem tawm qhov dhau. Yog tias muaj ob lub vaj huam sib luag ua, lub substrate

ntawm PCB yuav raug them nrog tooj liab ntawv ntawm ob sab. Lub rooj tsavxwm ntau txheej tuaj yeem siv los "nias" ob qho tib si ob sab

panels nrog tshwj xeeb adhesives.

 

Tom ntej no, koj tuaj yeem laum thiab phaj cov khoom xav tau ntawm PCB. Tom qab drilling lub tshuab raws li qhov xav tau drilling-

ements, lub qhov yuav tsum tau plated (plated los ntawm lub qhov technology, Plated-Through-Qhov

 

Technology, PTH). Tom qab kev kho hlau hauv lub qhov, cov txheej txheem sab hauv tuaj yeem txuas rau ib leeg.

 

Ua ntej pib plating, cov khib nyiab hauv lub qhov yuav tsum tau muab tshem tawm. Qhov no yog vim cov resin epoxy yuav muaj qee yam tshuaj

hloov tom qab cua sov, thiab nws yuav npog lub puab PCB txheej, yog li nws yuav tsum tau muab tshem tawm ua ntej. Ob qho kev tshem tawm thiab plating ua haujlwm-

ions tau ua tiav hauv cov txheej txheem tshuaj. Tom ntej no, nws yog tsim nyog los npog lub solder resist (solder resist number case) nyob rau sab nrauv wiri

ng kom cov xaim tsis kov cov plating feem.

 

Tom qab ntawd, ntau yam cim cim tau luam tawm ntawm lub rooj tsav xwm hauv Circuit Court los qhia qhov chaw ntawm txhua qhov chaw. Nws tsis tuaj yeem npog

ib qho xov hlau lossis cov ntiv tes kub, txwv tsis pub nws yuav txo tau cov solderability lossis kev ruaj ntseg ntawm kev sib txuas tam sim no. Ntxiv rau, yog tias

muaj kev sib txuas ntawm cov hlau, qhov "golden ntiv tes" feem ntau yog plated nrog kub, yog li ntawd qhov kev sib txuas zoo tam sim no ca-

n yuav tsum tau xyuas kom meej thaum muab tso rau hauv lub expansion qhov.

 

Thaum kawg, nws raug sim. Kuaj PCB rau luv luv lossis qhib circuits thiab sim nws optically lossis electronically. Optical scanning yog siv rau

nrhiav qhov tsis xws luag hauv txhua txheej, thiab kev ntsuas hluav taws xob feem ntau ua nrog Flying-Probe los xyuas txhua qhov kev sib txuas. Electronic test-

s yog qhov tseeb dua hauv kev nrhiav cov luv luv lossis qhib circuits, tab sis kev kuaj pom pom tau yooj yim dua pom cov teeb meem nrog qhov tsis raug-

t qhov sib txawv ntawm cov conductors.

 

Tom qab lub Circuit Court board substrate tiav lawm, ib tug tiav lawm motherboard yog nruab nrog ntau yam Cheebtsam ntawm lub PCB sub-

xaiv raws li xav tau. Ua ntej, SMT tsis siv neeg tso tshuab yog siv los "weld" IC nti thiab cov khoom siv nti, thiab th-

en manually txuas nws. Ntxig qee lub tshuab uas tsis tuaj yeem ua haujlwm, thiab txhim kho cov ntsaws-hauv cov khoom ntawm PCB thr-

Ough cov txheej txheem yoj / reflow soldering, yog li lub motherboard yog tsim.

 

Tsis tas li ntawd, yog tias lub rooj tsavxwm yuav tsum tau siv los ua cov motherboard ntawm lub khoos phis tawj, nws yuav tsum tau ua rau cov boards sib txawv. AT boar-

d hom yog ib qho ntawm cov txheej txheem yooj yim tshaj plaws ntawm pawg thawj coj saib, uas muaj cov qauv yooj yim thiab tus nqi qis. Nws tus qauv loj yog 33.2cmX30.48

cm. AT board yuav tsum tau siv ua ke nrog AT chassis fais fab mov thiab tau raug tshem tawm. ATX board zoo li ib

loj AT board. Qhov no ua rau nws yooj yim rau ATX chassis kiv cua kom dissipate CPU. Feem ntau ntawm cov chaw nres nkoj sab nraud ntawm lub rooj tsavxwm yog int-

egrated ntawm lub motherboard, tsis zoo li ntau COM ports ntawm AT board. Lub chaw luam ntawv yuav tsum cia siab rau kev sib txuas rau cov zis.

Tsis tas li ntawd, ATX kuj muaj Micro

 

ATX daim ntawv me me txhawb nqa txog li plaub qhov kev nthuav dav, txo qhov loj thiab siv zog thiab nqi.
