Sihlala sibuzwa malunga nokuguquguquka. Kakade ke, kutheni ungadinga ibhodi "eguquguqukayo"?
"Ngaba ibhodi eguquguqukayo iza kuqhekeka ukuba isebenzisa i-ED copper kuyo?"
Kweli nqaku singathanda ukuphanda izinto ezimbini ezahlukeneyo (i-ED-Electrodeposited kunye ne-RA-rolled-annealed) kwaye sibone impembelelo yazo kwixesha elide leesekethe. Nangona ziqondwa kakuhle lishishini le-flex, asifumani loo myalezo ubalulekileyo kumyili webhodi.
Masithathe umzuzwana sihlolisise ezi ntlobo zimbini zefoyile. Nantsi indlela ebonwa ngayo i-RA Copper kunye ne-ED Copper:
Ukuguquguquka kobhedu kuvela kwizinto ezininzi. Kakade ke, okuncinci yikopolo, kokukhona ibhodi iguquguquka ngakumbi. Ukongeza kubukhulu (okanye ukubhitya), iinkozo zobhedu nazo zichaphazela ukuguquguquka. Kukho iintlobo ezimbini eziqhelekileyo zobhedu ezisetyenziswa kwiimarike ze-PCB kunye nezesekethe ze-flex: i-ED kunye ne-RA njengoko kukhankanyiwe ngaphambili.
I-Roll Anneal Copper Foil (i-RA copper)
I-Rolled Annealed (RA) Copper isetyenzisiwe kakhulu kwimveliso yesekethe eziguquguqukayo kunye noshishino lokwenziwa kwe-PCB eziqinileyo kangangamashumi eminyaka.
Ulwakhiwo lwengqolowa kunye nomphezulu ogudileyo zilungele ukusetyenziswa kwesekethe eziguquguqukayo neziguquguqukayo. Enye indawo enomdla kwiintlobo zekopolo ezigoqiweyo ikhona kwiisignali kunye nokusetyenziswa kwe-high-frequency.
Kuye kwafunyaniswa ukuba uburhabaxa bomphezulu wobhedu bunokuchaphazela ukulahleka kokufakwa rhoqo kwaye umphezulu wobhedu ogudileyo uluncedo.
I-Electrolysis Deposition Copper Foil (i-ED copper)
Nge-ED copper, kukho iintlobo ngeentlobo zeefoils malunga noburhabaxa bomphezulu, unyango, ulwakhiwo lweenkozo, njl. Njengengxelo eqhelekileyo, i-ED copper inesakhiwo seenkozo ezithe nkqo. I-ED copper eqhelekileyo idla ngokuba nomphezulu ophakamileyo okanye orhabaxa xa ithelekiswa neRolled Annealed (RA) Copper. I-ED copper idla ngokuswela ukuguquguquka kwaye ayikhuthazi ukuthembeka okuhle kwesiginali.
I-EA copper ayifanelekanga kwimigca emincinci kunye nokumelana nokugoba okubi ngoko ke i-RA copper isetyenziselwa i-PCB eguquguqukayo.
Nangona kunjalo, akukho sizathu sokoyika i-ED copper kwizicelo eziguqukayo.
Nangona kunjalo, akukho sizathu sokoyika i-ED copper kwizicelo ezitshintshayo. Ngokuchaseneyo, lukhetho oluqhelekileyo kwizicelo zabathengi ezincinci nezilula ezifuna amazinga aphezulu omjikelo. Ingxaki kuphela kukulawula ngononophelo apho sisebenzisa khona iplating "eyongeziweyo" kwinkqubo ye-PTH. I-RA foil yeyona ndlela ifumanekayo kwiisisindo zobhedu ezinzima (ngaphezulu kwe-1 oz.) apho kufuneka khona izicelo zamandla ombane ezinzima kunye nokuguquguquka okuguquguqukayo.
Ukuze uqonde iingenelo kunye nokungalungi kwezi zinto zimbini, kubalulekile ukuqonda iingenelo kwixabiso kunye nokusebenza kwezi ntlobo zimbini zefoyile yobhedu, kwaye kubaluleke ngokufanayo, oko kufumaneka kurhwebo. Umyili kufuneka acinge kungekuphela nje ukuba yintoni eza kusebenza, kodwa nokuba ingafumaneka ngexabiso elingayi kuyisusa imveliso yokugqibela kwimarike ngokwexabiso.
