Kuyaziwa ukuba iibhodi zesekethe eziprintiweyo (Ii-PCBs) ziyinxalenye ebalulekileyo yazo zonke izixhobo ze-elektroniki kunye zombane. Iindidi ezininzi ze-PCB ziyafumaneka kulungelelwaniso kunye neelayile, kuxhomekeke kwiimfuno zesicelo. I-PCB inokuba nayo okanye ingenayo ingundoqo yesinyithi. Uninzi lwee-PCB zesiseko zentsimbi zenziwe ngealuminium, ngelixa iiPCB ezisemgangathweni zenziwe zangaphantsi kwesinyithi ezinje ngeceram, iplastikhi, okanye ifilglass. Ngenxa yendlela ezakhiwe ngayo, kukho umahluko phakathi kweepleyiti zealuminium kunye neePCB eziqhelekileyo. Yeyiphi engcono? Zeziphi ezi ntlobo zimbini ze-PCB ezilungele iimfuno zakho zesicelo? Masifumane into efanayo apha.

Thelekisa kunye nolwazi: IAluminiyam xa ithelekiswa neePCB eziqhelekileyo

Ukuthelekisa ialuminiyam neePCB eziqhelekileyo, kubalulekile ukuqwalasela iimfuno zakho zesicelo kuqala. Ukongeza kuyilo, ubhetyebhetye, uhlahlo-lwabiwo mali, kunye nokunye ukuthathelwa ingqalelo, kubalulekile ngokulinganayo. Ke, nolu ulwazi oluthe kratya kwi-PCB esemgangathweni kunye nealuminium ukukunceda ubone i-PCB oyifunayo.

Olunye ulwazi malunga neePCB eziqhelekileyo

Njengoko igama lisitsho, ii-PCB ezisemgangathweni zenziwe kwezona ndawo zisemgangathweni kwaye zisetyenziswa ngokubanzi. Ezi PCB zihlala zenziwe nge-FR4 substrates kwaye zinobungakanani obuqhelekileyo malunga ne-1.5mm. Ziyabiza kakhulu kwaye zinokuqina okuphakathi. Kuba izinto ze-substrate zee-PCB eziqhelekileyo zii-conductor ezihlwempuzekileyo, zine-lamination ye-copper, i-solder ethintela ifilimu, kunye nokushicilela kwesikrini ukubenza baqhube. Ezi zinokuthi zingatshatanga, ziphindwe kabini, okanye zininzi. Icala elinye lezixhobo ezisisiseko ezinje ngee-calculators. Izixhobo ezibekiweyo zisetyenziswa kwizixhobo ezintsonkothe ​​ngakumbi, ezinje ngeekhompyuter. Ke, kuxhomekeke kwinani lezinto ezisetyenzisiweyo kunye neendlela ezisetyenzisiweyo, zisetyenziswa kwizixhobo ezininzi ezilula nezintsonkothileyo. Uninzi lweepleyiti ze-FR4 alunako ukumelana nobushushu okanye ubushushu, ngenxa yoko ukubekwa ngokuthe ngqo kumaqondo obushushu aphezulu kufuneka kuthintelwe. Ngenxa yoko, baneesinki zokufudumeza ubushushu okanye izithuba zobhedu ezizaliswe yimingxunya ethintela ubushushu ekungeneni kwisekethe. Unokukuphepha ukusebenzisa ii-PCB eziqhelekileyo kwaye ukhethe ii-aluminium PCBS xa amaqondo obushushu aphezulu engafuneki ukuba asebenze kumaqondo obushushu aphezulu. Nangona kunjalo, ukuba iimfuno zesicelo sakho zizinzile, ubekwe kakuhle ukuba ukhethe ii-PCB zemigangatho ye-fiberglass efanelekileyo neyoqoqosho.

Kukho ulwazi oluthe kratya malunga ne-aluminium PCB

I-Aluminium PCB ifana nayo nayiphi na enye i-PCB apho i-aluminium isetyenziswa njenge-substrate. Zisetyenziswa ngokubanzi kwizicelo ezininzi ezisebenza kwindawo ezigadalala kunye namaqondo obushushu agqithisileyo. Kodwa azisetyenziswanga kuyilo oluntsonkothileyo olufuna ukuba kufakelwe izinto ezininzi. I-Aluminium ngumqhubi ofanelekileyo wobushushu. Nangona kunjalo, ezi PCBs zisenalo ukuprinta kwescreen, ubhedu kunye nemaleko yokumelana ne-solder. Ngamanye amaxesha i-aluminium inokusetyenziswa njenge-substrate ngokudibeneyo kunye nezinye izinto ezingasebenziyo, ezinjengeentsinga zeglasi. IAluminiyam i-PCB ubukhulu becala ayitshatanga okanye iphindwe kabini. Banqabile ukuba banemigangatho emininzi. Ke ngoko, nangona zibahambisa ubushushu, ukubekwa kwePCB yealuminium kuzisa imiceli mngeni yayo. Zisetyenziswa ngokubanzi kwiinkqubo zokukhanyisa ze-LED zangaphakathi nangaphandle. Zirhabaxa kwaye ziyanceda ukunciphisa ifuthe kwindalo esingqongileyo.
