7. Kev paub txog BGA
BGA CHIP PLACEMENT THIAB Routing RULE
BGA yog cov khoom siv feem ntau ntawm PCB, feem ntau yog CPU, NORTH BRIDGE, SOUTH BRIDGE, AGP CHIP, CARD BUS CHIP, thiab lwm yam. Feem ntau ntawm lawv yog nyob rau hauv hom bga ntim. Hauv luv luv, 80% ntawm cov teeb liab zaus thiab cov cim tshwj xeeb yuav rub tawm hom pob no. Yog li ntawd, yuav ua li cas los daws cov teeb meem ntawm BGA pob yuav muaj kev cuam tshuam zoo rau cov cim tseem ceeb.
Qhov me me uas feem ntau nyob ib puag ncig BGA tuaj yeem muab faib ua ob peb pawg raws li lawv qhov tseem ceeb
hla dhau.
Lub moos Terminal RC Circuit Court.
damping (pom nyob rau hauv series resistor, bank hom; piv txwv li, nco BUS teeb liab)
EMI RC Circuit Court (tshem tawm hauv damping, C, rub qhov siab style; xws li USB teeb liab).
Lwm yam tshwj xeeb circuits (tshwj xeeb circuits ntxiv raws li CHIP sib txawv; piv txwv li, qhov ntsuas kub ntawm CPU).
Cov pab pawg hluav taws xob me me ntawm 40mil lossis tsawg dua (hauv daim ntawv C, L, R, thiab lwm yam.; hom Circuit Court no feem ntau tshwm nyob ze ntawm AGP CHIP lossis CHIP nrog AGP muaj nuj nqi, thiab ntau pawg hluav taws xob sib cais los ntawm R, L).
Rub qis R, C.
General me me Circuit Court pawg (tso nyob rau hauv R, C, Q, U, thiab lwm yam.
Rub qhov siab R, RP.
1-6- khoom Circuit Court feem ntau yog qhov tseem ceeb ntawm kev tso kawm, thiab nws yuav tsum tau npaj kom ze rau BGA li sai tau, uas yuav tsum tau kho tshwj xeeb. Qhov tseem ceeb ntawm xya Circuit Court yog qhov thib ob, tab sis nws tseem yuav nyob ze rau BGA. 8, 9 yog ib lub voj voog dav dav, nws yog lub teeb liab tuaj yeem txuas nrog.
Kev txheeb ze ntawm qhov tseem ceeb ntawm qhov tseem ceeb ntawm qhov me me nyob ib puag ncig ntawm BGA saum toj no, cov cai ntawm ROUTING yog raws li hauv qab no:
by pass =>Thaum nws nyob ntawm tib sab li CHIP, nws txuas ncaj qha los ntawm CHIP tus pin mus dhau, ces dhau los ntawm kev rub tawm ntawm lub dav hlau; thaum nws txawv ntawm CHIP, nws tuaj yeem sib koom ua ke ntawm BGA's VCC thiab GND pins. 100 mil.
Clock terminal RC circuit =>Cable dav, xaim sib nrug, xaim ntev, lossis pob GND; Khaws cov cim kom luv thiab du raws li qhov ua tau, tsis hla VCC faib.
Damping =>Wireline dav, kab sib nrug, kab ntev, thiab pab pawg kab; cov kab yuav tsum yog luv thiab du li sai tau, thiab ib txheej ntawm cov kab yuav tsumtsis txhob sib xyaw nrog lwm cov cim..
EMI RC Circuits =>Cable dav, kab sib nrug, kab sib txuas, pob GND thiab lwm yam yuav tsum tau ua; ua tiav raws li cov neeg siv khoom xav tau.
Other special circuits =>Wireline dav, pob GND lossis cov kev cai tshem tawm; ua tiav raws li cov neeg siv khoom xav tau.
40milthe following small power circuit group =>Cable dav thiab lwm yam kev xav tau; Ua kom tiav cov txheej txheej saum npoo kom ntau li ntau tau kom khaws cia tag nrhosab hauv qhov chaw rau cov teeb liab kab, thiab sim kom tsis txhob muaj hluav taws xob teeb liab hla cov khaubncaws sab nraud povtseg
hauv cheeb tsam BGA, ua rau muaj kev cuam tshuam tsis tsim nyog.
Pull low R, C =>Tsis muaj kev cai tshwj xeeb; cov kab du.
General small circuit group =>Tsis muaj kev cai tshwj xeeb; cov kab du.
Pull height R,RP =>Tsis muaj kev cai tshwj xeeb; cov kab du.
