Kev khawb av
Lub Hom Phiaj
Tho qhov/qhov dig muag ntawm CCLs los tsim kev sib txuas ntawm cov txheej circuit thiab ntawm cov khoom siv thiab cov circuits.
Al: cua sov dissipation
Tooj liab ntawv ci: txheej conductive
Baseboard: tiv thaiv kev puas tsuaj ntawm lub laum
Cov xwm txheej thiab peev xwm ntawm kev khawb av
1. Cov xwm txheej ntawm kev khawb av:
* Pub: Qhov tob ntawm kev khawb ib feeb
* Kev Ceev: Tus naj npawb ntawm kev tig ib feeb
* Tus nqi tshem tawm cov khib nyiab: Qhov tob uas tuaj yeem nkag mus los ntawm txhua qhov kev sib hloov yog nws cov nqi tshem tawm cov khib nyiab
2. Muaj peev xwm khawb tau:
* Qhov tsawg kawg nkaus qhov loj me: yog tias muaj qhov drilled mechanically, qhov tsawg kawg nkaus qhov loj me yog 0.2 hli
* Qhov chaw kam rau siab (feem ntau ± 3mil)
* Qhov loj me kam rau siab (feem ntau + 0 / -1mil)
