Kumvetsetsa Kusiyana Pakati pa Aluminiyamu Board Ndi PCB

Kodi aluminium board ndi chiyani

Aluminiyamu board ndi mtundu wazitsulo zopangidwa ndi zitsulo zamkuwa zokhala ndi ntchito yabwino yoziziritsira kutentha.Nthawi zambiri, gulu limodzi limapangidwa ndi zigawo zitatu, zomwe ndi zosanjikiza zozungulira (zojambula zamkuwa), zosanjikiza zotsekera ndi zitsulo.Ndizofala muzinthu zowunikira za LED.Pali mbali ziwiri, mbali imodzi ya woyera ndi welded led pini, mbali inayo ndi aluminiyamu mtundu, zambiri yokutidwa ndi kutentha conduction phala ndi kukhudzana ndi kutentha conduction gawo.Palinso bolodi la ceramic ndi zina zotero.

PCB ndi chiyani

PCB board nthawi zambiri imatanthawuza bolodi losindikizidwa.PCB (PCB board), yomwe imadziwikanso kuti PCB, ndi omwe amalumikizana ndi zida zamagetsi zamagetsi.Yakhala ikukula kwa zaka zoposa 100;Kapangidwe kake ndi kamangidwe kake;Ubwino waukulu wogwiritsa ntchito bolodi la dera ndikuchepetsa zolakwika zama waya ndi msonkhano kwambiri, ndikuwongolera kuchuluka kwa zochita zokha komanso kuchuluka kwa ntchito.

Malingana ndi chiwerengero cha zigawo za matabwa a dera, akhoza kugawidwa mu gulu limodzi, bolodi lokhala ndi mbali ziwiri, bolodi lamagulu anayi, bolodi lachisanu ndi chimodzi ndi matabwa ena ozungulira.Popeza kusindikizidwa dera bolodi si ambiri mapeto mankhwala, ndi pang'ono kusokonezeka mu tanthauzo la dzina.Mwachitsanzo, mavabodi kompyuta munthu amatchedwa mavabodi, koma osati mwachindunji amatchedwa dera bolodi.Ngakhale pali matabwa ozungulira mu bolodi lalikulu, sizili zofanana, choncho sikoyenera kunena zomwezo poyesa makampani.Mwachitsanzo, chifukwa pali zigawo za IC zopakidwa pa bolodi ladera, atolankhani amamutcha IC board, koma kwenikweni, sali wofanana ndi bolodi losindikizidwa.Nthawi zambiri timatchula bolodi losindikizidwa ngati bolodi lopanda kanthu - ndiko kuti, bolodi lopanda zinthu zapamwamba.

Kusiyana pakati pa bolodi la aluminiyamu ndi bolodi la PCB

Kwa abwenzi ena ang'onoang'ono omwe angoyamba kumene mu malonda a aluminiyamu, padzakhala funso lotere.Ndiko kuti, pali kusiyana kotani pakati pa bolodi la aluminiyamu ndi bolodi la PCB.Kwa funso ili, gawo lotsatirali likuuzani ndendende kusiyana komwe kulipo pakati pa awiriwa?

PCB bolodi ndi zitsulo zotayidwa bolodi amapangidwa malinga ndi zofunikira za PCB.Pakadali pano, bolodi ya aluminium yochokera ku PCB pamsika nthawi zambiri imakhala yambali imodzi.PCB bolodi ndi mtundu waukulu, zotayidwa bolodi ndi mtundu umodzi wa bolodi PCB, ndi zotayidwa zitsulo mbale.Chifukwa cha matenthedwe ake abwino, amagwiritsidwa ntchito m'makampani a LED.

PCB bolodi zambiri mkuwa bolodi, amenenso anawagawa gulu limodzi ndi awiri mbali bolodi.Zomwe zimagwiritsidwa ntchito pakati pa ziwirizi ndizosiyana kwambiri.Zinthu zazikulu za aluminiyumu bolodi ndi mbale zotayidwa, ndipo zinthu zazikulu za PCB board ndi mkuwa.Aluminium board ndi yapadera pazinthu zake za PP.Kutentha kwapakati ndikwabwino kwambiri.Mtengo wake ndiwokweranso ndithu

Poyerekeza ndi awiri mu kutentha dissipation, ntchito ya bolodi zotayidwa kutentha dissipation ndi kuposa PCB bolodi, ndi matenthedwe madutsidwe ake ndi osiyana PCB, ndi mtengo wa bolodi zotayidwa ndi okwera mtengo.
