Kumvetsetsa kusiyana pakati pa bolodi ya aluminium ndi PCB

Kodi zotayidwa ndi chiyani

 

Aluminiyamu board ndi mtundu wachitsulo chovekedwa ndi chitsulo chokhala ndi bolodi labwino lomwe limatha kutentha. Nthawi zambiri, gulu limodzi limapangidwa ndi zigawo zitatu, zomwe ndizosanjikiza dera (zojambulazo zamkuwa), zotchinjiriza zosanjikiza ndi zitsulo zosanjikiza. Ndizofala pazowunikira za LED. Pali mbali ziwiri, mbali imodzi yoyera ndi pini lotsogozedwa, mbali inayo ndi mtundu wa aluminium, womwe umakhala wokutidwa ndi phala loyendetsa ndikumalumikizana ndi gawo lotentha. Palinso bolodi la ceramic ndi zina zotero.

 

PCB ndi chiyani?

 

PCB bolodi nthawi zambiri limatanthawuza kusindikiza kwa bolodi. PCB (PCB board), yomwe imadziwikanso kuti PCB, ndi yomwe imathandizira kulumikizana kwamagetsi kwamagetsi. Zakhala zikuchitika kwa zaka zoposa 100; Mamangidwe ake makamaka masanjidwe kapangidwe; Ubwino waukulu wogwiritsa ntchito bolodi la dera ndikuchepetsa zolakwika za zingwe ndi msonkhano kwambiri, ndikuwongolera magwiridwe antchito ndi kuchuluka kwa ntchito.

 

Malinga ndi kuchuluka kwa zigawo zama board, amatha kugawidwa pagulu limodzi, mbali ziwiri, bolodi lazitsulo zinayi, bolodi lachisanu ndi chimodzi ndi ma board ena azigawo zingapo. Popeza kusindikiza kwa board board sikumakhala kotuluka konse, ndizosokoneza pang'ono tanthauzo la dzina. Mwachitsanzo, bolodi la amayi pamakompyuta amatchedwa mavabodi, koma osatchedwa mwachindunji board board. Ngakhale pali bolodi lamayendedwe mu bolodi lalikulu, silofanana, kotero sikofunikira kunena chimodzimodzi poyesa makampani. Mwachitsanzo, chifukwa pali magawo a IC omwe amanyamula pa board board, atolankhani amamutcha kuti IC board, komatu, siwofanana ndi board board. Nthawi zambiri timakonda kunena za bolodi loyenda ngati bolodi lopanda kanthu - ndiye kuti, bolodi loyendetsa popanda chopangira chapamwamba.

 

Kusiyana pakati pa bolodi ya aluminiyamu ndi bolodi la PCB

 

Kwa anzawo ang'onoang'ono omwe angoyamba kumene kupanga bizinesi yama aluminiyamu, padzakhala funso lotere. Ndiye kuti, pali kusiyana kotani pakati pa bolodi ya aluminium ndi bolodi ya PCB. Pafunso ili, gawo lotsatirali likuwuzani zenizeni zomwe pali kusiyana pakati pa awiriwa?

 

PCB board ndi board ya aluminiyamu yapangidwa molingana ndi zofunikira za PCB. Pakadali pano, board ya aluminium yochokera ku PCB pamsika nthawi zambiri imakhala yama aluminiyamu amodzi. PCB board ndi mtundu waukulu, board ya aluminium ndi mtundu umodzi wokha wa board ya PCB, ndi mbale ya aluminium yozikidwa ndi chitsulo. Chifukwa cha kutentha kwake kotentha, imagwiritsidwa ntchito kwambiri pamakampani a LED.

 

Bokosi la PCB nthawi zambiri limakhala bolodi lamkuwa, lomwe limagawidwanso pagulu limodzi komanso gulu lokhala ndi mbali ziwiri. Zomwe zimagwiritsidwa ntchito pakati pa ziwirizi ndizosiyana kwambiri. Zinthu zazikulu za bolodi ya aluminiyamu ndi mbale ya aluminiyamu, ndipo zinthu zazikulu za board ya PCB ndi mkuwa. Aluminium board ndiyapadera pazinthu zake za PP. Kutaya kutentha ndikwabwino. Mtengo ulinso wokwera mtengo

 

Poyerekeza ndi kutaya kwa kutentha, magwiridwe antchito a zotayidwa amatentha kwambiri kuposa PCB, ndipo matenthedwe ake otentha ndiosiyana ndi a PCB, ndipo mtengo wa board ya aluminium ndiwokwera mtengo.
