Dab tsi yog qhov txawv ntawm PCB ib txheej board, ob-txheej board thiab multi-layer board
1. Ib leeg-Sided Boards
Peb nyuam qhuav hais tias ntawm qhov yooj yim tshaj plaws PCB, cov khoom yog concentrated ntawm ib sab thiab cov xov hlau yog concentrated rau sab nraud. Vim hais tias cov xov hlau tsuas yog tshwm sim ntawm ib sab, peb hu qhov no PCB lub rooj tsavxwm ib leeg.
Vim hais tias lub rooj tsavxwm ib txheej muaj ntau qhov kev txwv nruj ntawm cov qauv tsim (vim tias tsuas muaj ib sab xwb, cov xov hlau tsis tuaj yeem hla thiab yuav tsum mus ncig ntawm ib qho kev sib cais), yog li tsuas yog cov khoom siv hluav taws xob thaum ntxov siv hom board, lossis qee qhov yooj yim PCBAs. yuav siv lub rooj tsavxwm no.
2. Ob Chav Sided Boards
Lub rooj tsavxwm no muaj cov hlua ntawm ob sab. Txawm li cas los xij, txhawm rau siv ob sab ntawm cov hlau, yuav tsum muaj kev sib txuas kom raug ntawm ob sab. Xws li "choj" ntawm circuits yog hu ua vias. Vias yog qhov me me ntawm PCB, ntim lossis pleev xim nrog hlau, uas tuaj yeem txuas nrog cov xov hlau ntawm ob sab. Vim hais tias thaj tsam ntawm lub rooj tsavxwm ob txheej yog ob zaug loj dua li ntawm ib txheej txheej txheej, thiab vim hais tias cov xaim tuaj yeem cuam tshuam (tuaj yeem raug mob rau sab nraud), nws yog qhov tsim nyog rau kev siv ntawm ntau lub voj voog ntau dua. ib txheej boards. Hais txog kev hais lus, qhov no yog siv ntau dua.
3. Multi-Layer Boards
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Multi-txheej boards siv ob peb txheej txheej boards, thiab muab ib txheej ntawm insulating txheej ntawm txhua txheej ntawm cov laug cam thiab ces nplaum lawv (nias). Tus naj npawb ntawm cov khaubncaws sab nraud povtseg sawv cev rau ob peb txheej txheej txheej txheej, feem ntau cov txheej txheem yog txawm, thiab suav nrog ob txheej txheej sab nraud. Feem ntau cov motherboards yog 4 mus rau 8 txheej ntawm cov qauv, tab sis technically nws muaj peev xwm ua tiav ze li ntawm 100 txheej ntawm PCB boards.
Peb BQC tshwj xeeb hauv PCBA kev tsim khoom rau ntau tshaj 19 xyoo, peb ib txwm yuav cov txheej txheem ib nrab ntawm cov khoom siv hluav taws xob raws li cov neeg siv khoom xav tau.
