Icala-linye elibhetyebhetye ibhodi yesekethe eprintiweyo (PCB) zineenzuzo ezininzi xa zisetyenziselwa ukupakishwa okanye njengenxalenye yenkqubo. Ezi PCBS bezikho ukusukela ngeminyaka yoo-1950 kwaye zisathandwa. Eli nqaku liphonononga izizathu zophononongo lwabo oluqhubekayo oluhle.

Ulwakhiwo olusisiseko lwesekethe eguquguqukayo enecala elinye

I-PCBS enecala elinye iqulathe umaleko omnye wezinto zokuqhuba kwaye ilungele uyilo olunoxinano oluphantsi. Ulwakhiwo olusisiseko lwe-PCB enecala elinye eguquguqukayo lubandakanya:

Umaleko we-polyimide

Uluhlu lweglue

I-conductor layer – ubhedu

Uluhlu lwepolyamide

Iimeko zokusebenzisa iPCB enecala elinye

I-conductor layer – ubhedu

umaleko weglu

Inkonzo eguquguqukayo/ufakelo

Usetyenziso lwePCB enecala elinye

I-PCBS enecala elinye ilula kakhulu, kodwa inokusetyenziswa kwiisekethe eziyinkimbinkimbi. Nazi ezinye izicelo ezidumileyo zePCBS enecala elinye.

Ukunikezelwa kwamandla

Isiphaluka sexesha

Ikhalityhuleyitha yedijithali

Ukukhanya kwe-LED

Izixhobo zokupakisha

Usasazo kunye nezixhobo zestereo

Inkqubo yekhamera

Umeshini wokuthengisa

Imbiza yekofu

Ukuqhuba kukarhulumente oqinileyo

Izibonelelo zesekethe enye eguqukayo

Ezi zibonelelo zilandelayo zePCBS enecala elinye zibonisa ukuthandwa kwazo:

Ubuncinci beengxaki zokuvelisa: Ngeendlela zokuvelisa ezizenzekelayo kunye noyilo oluchanekileyo, iisekethe eziguquguqukayo zecala elinye zinciphisa ukubakho kwempazamo yomntu. Oku kuphakamisa amathuba amancinci okudala ingxaki.

Iyafikeleleka: Lo ngoyena mqhubi uphambili wokuthandwa kwePCBS enamacala obhedu akwicala elinye. Eziisekethi zifuna abasebenzi abancinci ukuba bahlangane. Ngokwesiqhelo, iinkqubo zokudibanisa ezipheleleyo ziyatshintshwa okanye zifakwe kwibhodi nganye yePC engqongqo. Oku kunceda ukunciphisa iimpazamo kunye nokulawula iindleko zokuvelisa. Ngoko ke, nokuba isetyenziselwa iprototyping, ukuyila umthamo omncinci okanye omkhulu, ixabiso liphantsi kwaye ixesha lokuguqula lifutshane.

Ukuthembeka: I-PCB enecala elinye eguquguqukayo inokugotywa kwaye ihanjiswe ngaphandle kwamathuba okusilela. Uzinzo thermal polyamides kwenza PCBS ukumelana amaqondo aphezulu kunye namaqondo obushushu.

Ubunzima obuncitshisiweyo kunye nobungakanani bepakethe: I-PCBS ethambileyo enecala elinye ineenxalenye ezincinci. Oku kubhitya kuthetha ukuyilwa lula, ukuguquguquka kunye nokunwebeka. Oku kunceda ukugcina ubunzima kunye nokunciphisa ubungakanani bephakheji. I-PCBS enecala elinye ngokuqinisekileyo iya kuqhubeka ithandwa njengoko imfuno yeesekethe ezinobunzima obuphantsi iqhubeka ikhula.
