Ifoyile yobhedu yePCB

Ngenxa yokwanda kokusetyenziswa kwezixhobo zombane, imfuno yezi zixhobo ibisoloko iphezulu kwintengiso. Ezi zixhobo ngoku zisijikelezile njengoko sixhomekeke kakhulu kuzo ngeenjongo ezahlukeneyo. Ngesi sizathu, ndibheja ukuba ufumene isixhobo sombane okanye uhlala usisebenzisa ekhaya. Ukuba usebenzisa ezi zixhobo, unokuzibuza ukuba zifakwe njani iintambo zezixhobo ze-elektroniki, zisebenza njani, kwaye isixhobo sinokuqhagamshelwa njani kwezinye izinto. Izixhobo zombane esizisebenzisayo ekhaya zenziwe ngezinto ezingasebenzisi mbane. Zineendlela ezifakwe kwizinto zobhedu eziqhubayo kumphezulu wazo, zivumela umqondiso ukuba ugeleze ngaphakathi kwesixhobo xa sisebenza.

Ke ngoko, itekhnoloji yePCB isekwe ekuqondeni ukusebenza kwezixhobo zombane. I-PCB isoloko isetyenziswa kakhulu kwizixhobo zombane ezenzelwe imidiya. Nangona kunjalo, kwisizukulwana sanamhlanje, ziphunyezwa kuzo zonke izixhobo zombane. Ngesi sizathu, akukho sixhobo sombane sinokusebenza ngaphandle kwePCB. Le blog igxile kwifoyile yobhedu PCB, kunye nendima edlalwe yiifoyile yobhedukushishino lwebhodi yesekethe.

ITekhnoloji yeBhodi yeSekethe eShicileleyo (PCB).

I-PCBs ziindlela ezihamba ngombane njengemikhondo kunye neengoma, ezilaminethiweyo ngefoyile yobhedu. Oku kubenza baqhagamshele kwaye baxhase amanye amacandelo e-elektroniki aqhagamshelwe ngoomatshini kwisixhobo. Ngesi sizathu, umsebenzi ophambili wezi PCB kwizixhobo zombane kukubonelela ngenkxaso kwiindlela. Kwiimeko ezininzi, izinto ezifana ne-fiberglass kunye neeplastiki zibamba ngokulula i-foil yobhedu kwisekethe. I-foil yobhedu kwi-PCB ihlala i-laminated kunye ne-non-conductive substrate. Kwi-PCB, ifoyile yobhedu idlala indima ebalulekileyo ekuvumeleni ukuhamba kombane phakathi kwamacandelo ahlukeneyo esixhobo, ngaloo ndlela ixhasa unxibelelwano lwabo.

Amajoni ahlala eqhagamshela ngokufanelekileyo phakathi komphezulu wePCB kunye nezixhobo zombane. Ezi solder zenziwe kusetyenziswa intsimbi eyenza ibe yinto encamathelayo eyomeleleyo; ngenxa yoko, banokuthenjwa ekunikezeni inkxaso yomatshini kumacandelo. Umendo we-PCB udla ngokudityaniswa namaleya amaninzi ezinto ezahlukeneyo ezifana nescreen sesilika kunye neentsimbi ezilaminethiweyo ngesubstrate ukuze zibe PCB.

Indima yefoyile yobhedu kwishishini lebhodi yesekethe

Ubuchwephesha obutsha obuhamba phambili namhlanje buthetha ukuba akukho sixhobo sombane sinokusebenza ngaphandle kwePCB. I-PCB, kwelinye icala, ithembele ngakumbi kubhedu kunamanye amacandelo. Oku kungenxa yokuba ubhedu lunceda ukwenza imikhondo edibanisa onke amacandelo kwi-PCB ukuvumela ukuhamba kwentlawulo ngaphakathi kwesixhobo. Umkhondo unokuchazwa njengemithambo yegazi kumathambo e-PCB. Yiyo loo nto iPCB ayinakusebenza xa imikhondo ilahlekile. Xa iPCB isilela ukusebenza, isixhobo sombane siya kuphulukana nombono waso, sisenze singabi namsebenzi. Ke ngoko, ubhedu yeyona nxalenye iphambili yePCB. I-foil yobhedu kwi-PCB iqinisekisa ukuhamba rhoqo kweempawu ngaphandle kokuphazamiseka.

Izinto zobhedu zihlala ziyaziwa ngokuba ne-conductivity ephezulu kunezinye izinto ngenxa yee-electron zamahhala ezikhoyo kwigobolondo layo. Ii-electron zikhululekile ukuhamba ngaphandle kokuchasana nayo nayiphi na i-athomu eyenza ubhedu olukwazi ukuthwala iintlawulo zombane ezihambayo ngokufanelekileyo ngaphandle kokulahlekelwa okanye ukuphazamiseka kwiimpawu. Ubhedu, olwenza i-electrolyte engalunganga egqibeleleyo, isoloko isetyenziswa kwiiPCB njengomaleko wokuqala. Ngenxa yokuba ubhedu aluchatshazelwa kangako yioksijini engaphezulu, lunokusetyenziswa ziintlobo ezininzi ze-substrates, i-insulating layers, kunye nesinyithi. Xa isetyenziswe kunye nala ma-substrates, yenza iipatheni ezahlukeneyo kwisekethe, ngakumbi emva kokudibanisa. Oku kuhlala kwenzeka ngenxa yesakhono sobhedu ukwenza ibhondi egqibeleleyo kunye neeleya zokugquma ezisetyenziselwa ukwenza iPCB.

Kudla ngokubakho iileya ezintandathu zePCB eziyilwe, kuzo ezine umaleko kwiPCB. Ezinye iileya ezimbini zidla ngokudityaniswa kwiqela elingaphakathi. Ngesi sizathu, ezi maleko zimbini zezokusetyenziswa kwangaphakathi, kukwakho ezimbini zokusetyenziswa ngaphandle, kwaye ekugqibeleni, ezimbini ezishiyekileyo kwimigangatho emithandathu iyonke kukuphucula iiphaneli ngaphakathi kwePCB.

Ukuqukumbela

Ifoyile yobheduyinxalenye ebalulekileyo yePCB evumela ukuhamba kweentlawulo zombane ngaphandle kokuphazamiseka. Ine-conductivity ephezulu kwaye yenza ngokugqibeleleyo ibhondi eyomeleleyo kunye nezinto ezahlukeneyo zokugquma ezisetyenziswa kwibhodi yesekethe yePCB. Ngesi sizathu, i-PCB ixhomekeke kwifoyile yobhedu ukuze isebenze njengoko isenza udibaniso lwamathambo e-PCB lusebenze.
