Zotayidwa m'munsi pcb , tonse tikudziwa kuti zotayidwa ndi chitsulo, magetsi madutsidwe;

Kodi ntchito monga zakuthupi PCB?

Chifukwa gawo la aluminiyamu limapangidwa ndi zigawo zitatu, monga: mkuwa wojambula, zotchinjiriza zosanjikiza ndi zotayidwa zachitsulo. Popeza pali zotchinjiriza, kuphatikiza pakuzimitsa kutentha, matenthedwe owonjezera a coefficient, matenthedwe otentha, mphamvu, kuuma, kulemera, mawonekedwe apadziko ndi mtengo wa gawo lapansi lazitsulo liyeneranso kuganiziridwa.

Mwambiri, poganizira za mtengo ndi magwiridwe antchito, zotayidwa gawo lapansi ndiye chisankho choyenera.Zopezeka mbale ya aluminium 6061,5052,1060, ndi zina zotero zigawo zamkuwa zimapezekanso pazotentha, zamagetsi, zamagetsi, ndi zina zapadera, koma ndizokwera mtengo .

Amawonekera kwambiri mbali zonse za PCB. Mbali imodzi yokhala ndi mafuta okutira imakhala ndi zikhomo za LED, pomwe mbali inayo ikuwonetsa mtundu woyambirira wa aluminium. Nthawi zambiri, matenthedwe otentha amatha kugwiritsidwa ntchito kenako kulumikizana ndi gawo lotentha. Chimodzi mwazabwino zazikulu zamagawo a aluminiyamu pachikhalidwe cha FR-4 ndikuti amatha kukhala ndi mtunda wapamwamba.Ndipo kutentha kofulumira, magwiridwe antchito otentha.

Gawo la aluminiyamu limatha kuchepetsa kutentha kwakanthawi, kotero kuti gawo la aluminiyamu limakhala ndi magwiridwe antchito abwino otentha; Poyerekeza ndi gawo la ceramic, makina ake ndiabwino kwambiri.

Gawo la Aluminium lilinso ndi zotsatirazi:

Mogwirizana ndi zofunikira za RoHS zoteteza zachilengedwe, ndizoyenera kwambiri kuntchito za SMT zokhala ndi mphamvu yayitali yothanirana ndi kufalikira kwamakina pakapangidwe kazipangizo, kuti muchepetse kutentha kwa gawo, kukulitsa moyo wautumiki, ndikuwonjezera mphamvu zamagetsi ndi kudalirika;

Kuchepetsa kusonkhana kwa ma radiator ndi zida zina (kuphatikiza zida zamagetsi zamagetsi), kuchepetsa kuchuluka kwa zinthu, ndikuchepetsa zida zamagetsi ndi zamisonkhano; Konzani kuphatikiza kwa dera lamagetsi ndikuwongolera dera.

Zomwe zili pamwambazi ndizabwino za gawo la aluminiyamu, ndikhulupilira kuti mungakonde! Ndife PCB fakitale , tikukulandirani kuti mufunsane ndi zinthu zathu za PCB ~
