Kwihlabathi le-electronics, iiBhodi zeSekethe eziShicileleyo (iiPCB) zidlala indima ebalulekileyo ekudibaniseni amacandelo ahlukeneyo kunye nokuqinisekisa ukusebenza kakuhle.Imfuno yezixhobo ze-elektroniki ezincinci, ezisebenza ngakumbi, eziphucuke kakhulu zikhokelele kuhlumo olukhulu kwitekhnoloji ye-PCB ekuhambeni kweminyaka.Olunye uphuculo olunjalo yi-PCB enamaleko amaninzi, eya ithandwa ngakumbi kwizinto zombane zanamhlanje.Le bhlog ijolise ekukhanyiseleni ngokubaluleka kunye noncedo lwee-PCB zamanqanaba amaninzi kubuchwephesha obuguqukayo.
Funda malunga neePCB zamanqanaba amaninzi.
Ukuqonda ukubaluleka kwePCB enamaleko amaninzi, umntu kufuneka aqonde ubume bayo obusisiseko.Ngokungafaniyo nee-PCBs zemveli zodidi olunye okanye oluphindwe kabini, ii-PCB ze-multilayer zenziwe ngamacandelo amaninzi ezinto zokuqhuba ezahlulwe ngemathiriyeli ye-dielectric.Ezi maleko ziqhagamshelwe nge-vias, ezivumela imiqondiso yombane ukuba ihambe ngaphandle komthungo kwibhodi yesekethe.Inani leengqimba linokuvela kwisine ukuya kwishumi elinambini, kuxhomekeke kubunzima besekethe kunye neemfuno zesixhobo.
Izinto ezilungileyo zeI-PCB yamandla amaninzi:
1. Uyilo olubambeneyo: Ii-PCB ezininzi zenza ukuba abaqulunqi benze izixhobo zombane ezixineneyo nezincinci ngaphandle kokuphazamisa ukusebenza kwazo.Ukukwazi ukupakisha iileya ezininzi ngokuthe nkqo kuvumela ukusetyenziswa ngokufanelekileyo kwendawo kwaye kufanelekile kwiimveliso ezinje ngee-smartphones, izinto ezinxitywayo kunye nezixhobo zonyango.
2. Ukwandiswa komsebenzi: Iileya ezininzi kwi-PCB enamaleko amaninzi zinendawo eyongezelelweyo yokudibanisa amacandelo amaninzi kunye neesekethe ezinzima.Oku kuvumela ukubandakanywa kweempawu eziphambili ezifana nezakhono ezingenazintambo, iinkqubo zokulawula amandla, ukuhanjiswa kwedatha ye-high-speed, kunye nokunye.Ukusebenza okuphuculweyo okubonelelwa zii-PCB zamanqanaba amaninzi kwenza abavelisi bahlangabezane neemfuno ezikhulayo zentengiso.
3. Ingqibelelo yomqondiso kunye nokunciphisa i-EMI: Njengoko isantya sedatha siqhubeka sikhula kwaye ukuhanjiswa kwesignali ephezulu kuyadingeka, ii-PCB ezinamanqwanqwa amaninzi zigqwesa ekuqinisekiseni intembeko yesignali kunye nokunciphisa ukuphazamiseka kwe-electromagnetic (EMI).Ngokwahlula amandla kunye neenqwelomoya zomhlaba kwiindiza zesignali, ezi bhodi zinciphisa i-crosstalk kwaye zigcina ingqibelelo yeempawu ezibuthathaka.Oku kwandisa amazinga okudluliselwa kwedatha kwaye kunciphisa ithuba leempazamo okanye ukuphazamiseka.
4. Ukuthembeka okuphuculweyo: Xa kuthelekiswa ne-single-layer okanye i-double-layer PCB, i-PCB enemigangatho emininzi inokuthembeka okungcono.Ukusasazwa kunye nokuhanjiswa kwamacandelo kumacandelo amaninzi kunciphisa umngcipheko wenqaku elinye lokungaphumeleli.Ukongeza, ukucolwa komngxuma kunye ne-vias kuphucula ubume buphela kwaye kwenza ukuba ibhodi imelane noxinzelelo lwe-thermal kunye nokungcangcazela, iyenze ilungele usetyenziso kumacandelo eemoto, i-aerospace kunye neshishini.
5. Ukuguquguquka koyilo: Ukuguquguquka kwe-PCBs ye-multi-layer kwenza abaqulunqi basebenzise iiplani eziyinkimbinkimbi, ukudibanisa i-analog kunye neesekethe zedijithali.Oku bhetyebhetye kunika iinjineli inkululeko ethe kratya yokuvelisa izinto ezintsha kunye nokulungelelanisa inkqubo yoyilo.Ukongezelela, ukuguqulwa koyilo lweesekethe kunye neenguqu zingenziwa ngaphandle kokuchaphazela yonke ibhodi yebhodi, ukunciphisa ixesha lophuhliso kunye neendleko.
Ukuhlangabezana neemfuno zale mihla zombane:
Imfuno ekhulayo yezixhobo zombane ezincinci, ezikrelekrele zifuna ukusetyenziswa kweePCB ezinamaleko amaninzi.Ukukwazi kwabo ukwamkela ukusebenza okuthe kratya, ukubonelela ngemfezeko yophawu oluphuculweyo, ukuphucula ukuthembeka kunye nokubonelela ngobubhetyebhetye boyilo kubenza babe lukhetho olunobulumko kubavelisi abafuna ukuhlala phambi kobuchwephesha obuvela ngokukhawuleza.
Ii-PCB zeMultilayer ziye zaliguqula ishishini le-elektroniki ngokunikezela ngeenzuzo ezininzi kwiibhodi zesekethe zemveli.Njengoko imfuno yezixhobo ze-elektroniki ezidityanisiweyo ezihlanganisiweyo neziphucukileyo ziqhubeka nokukhula, ukubaluleka kweePCB ezinamaleko amaninzi kuya kucaca ngakumbi.Ngokwamkela le teknoloji, abavelisi banokuhlangabezana nemfuno yabathengi beemveliso ezintsha ngelixa beqinisekisa ukuthembeka, ukusebenza kunye nokwaneliseka jikelele kwabathengi.
