A pob kab sib chaws (BGA) yog ib hom ntim ntim ntim (ib lub thawv ntim khoom) siv rau kev sib xyaw ua keBGA pob siv los mus tas li mount cov khoom xws li microprocessors. BGA tuaj yeem muab cov pins sib txuas ntau dua li tuaj yeem muab tso rau ntawm ob sab hauv kab lossis pob tiaj tus.
Dab tsi yog Ball Grid Array Cheebtsam?
Ball grid array (BGA) yog ib hom kev siv thev naus laus zis (SMT) uas yog siv rau kev ntim khoom sib xyaw ua ke. … BGA Cheebtsam tau ntim khoom siv hluav taws xob rau hauv cov pob khoom txheem uas suav nrog ntau cov duab thiab ntau thiab tsawg.
Plastic Ball Grid Array yog dab tsi?
Plastic Ball Grid Array lossis PBGA pob, tsim nyog thiab ramped los ntawm Texas Instruments Philippines yog a kab noj hniav-up laminate raws li substrate pob nyob rau hauv uas cov tuag yog txuas rau lub substrate nyob rau hauv ib txwm tuag li. … PBGA pob khoom muaj nyob rau hauv 2 thiab 4 txheej substrate designs.
YPuas BGA a SMD?
BGA yog dab tsi? Lub Pob Grid Array Integrated Circuit yog a nto mount ntaus ntawv (SMD) tivthaivuas tsis muaj txhuas. Cov pob SMD no siv cov hlau spheres uas yog ua los ntawm cov hlau nplaum hu ua cov khoom siv rau kev sib txuas rau PCB (Printed Circuit Board).
BGA ua li cas?
A Ball Grid Array lossis BGA Assembly yog ib hom kev siv thev naus laus zis (SMT) uas siv cov pob me me hauv qab pob IC txhawm rau txuas rau lub substrate lossis PCB Cov kub no Cov khoom siv hluav taws xob xaim hluav taws xob rau cov cim rau BGA. BGA cov rooj sib txoos tau siv ntau zuj zus rau kev sib xyaw ua ke.
