Umahluko phakathi kwe-RA Copper kunye ne-ED Copper

Sisoloko sibuzwa malunga nokuba bhetyebhetye.Ewe kunjalo, kutheni ufuna enye ibhodi "flex"?

“Ingaba ibhodi eguquguqukayo iya kuqhekeka ukuba isebenzisa ubhedu lwe-ED kuyo?''

Ngaphakathi kweli nqaku singathanda ukuphanda izinto ezimbini ezahlukeneyo (i-ED-Electrodeposited kunye ne-RA-rolled-annealed) kwaye sibone impembelelo yazo kubude besiphaluka.Nangona siqondwa kakuhle lishishini eliguqukayo, asifumani umyalezo obalulekileyo kumyili webhodi.

Makhe sithathe umzuzwana sihlolisise ezi ntlobo zimbini zefoyile.Nalu uqwalaselo olunqamlezileyo lweRA Copper kunye ne-ED Copper:

ED COPPER VS RA COPPER

Ukuguquguquka kobhedu kuvela kwizinto ezininzi.Ngokuqinisekileyo, i-thinner i-copper, ibhodi eguquguqukayo ngakumbi.Ukongeza kwi-thickness (okanye encinci), ingqolowa yobhedu nayo ichaphazela ukuguquguquka.Kukho iintlobo ezimbini eziqhelekileyo zobhedu ezisetyenziswa kwi-PCB kunye neemarike zeesekethe ze-flex: ED kunye ne-RA njengoko kukhankanywe ngasentla.

Roll i-Anneal Copper Foil (i-RA yobhedu)
I-Rolled Annealed (RA) I-Copper isetyenziswe kakhulu kwi-flex flex circuits ukuveliswa kunye ne-rigid-flex-flex imboni ye-PCB yokwenza i-PCB amashumi eminyaka.
Ukwakhiwa kweenkozo kunye nomphezulu ogudileyo ulungele ukusetyenziswa okuguquguqukayo, okuguquguqukayo kweesekethe.Enye indawo enomdla kunye neentlobo zobhedu eziqengqelekayo zikhona kwiimpawu ze-high-frequency kunye nezicelo.
Kufunyaniswe ukuba uburhabaxa bomphezulu wobhedu bunokuchaphazela ilahleko yokufaka i-frequency ephezulu kwaye umphezulu wobhedu ogudileyo unenzuzo.

Electrolysis Deposition Copper Foil (ED copper)
Ngobhedu lwe-ED, kukho ukwahlukana okukhulu kweefoyile malunga noburhabaxa bomphezulu, unyango, ukwakheka kweenkozo, njl.Ubhedu oluqhelekileyo lwe-ED lunenkangeleko ephezulu okanye indawo erhabaxa xa kuthelekiswa neRolled Annealed (RA) Copper.Ubhedu lwe-ED ludla ngokuswela ukuguquguquka kwaye alukhuthazi ingqibelelo yesiginali elungileyo.
Ubhedu lwe-EA alufanelekanga kwimigca emincinci kunye nokumelana nokugoba okubi ukuze i-RA yobhedu isetyenziswe kwi-PCB eguquguqukayo.
Nangona kunjalo, akukho sizathu sokwesaba ubhedu lwe-ED kwizicelo ezinamandla.

COPPER FOIL -cHINA

Nangona kunjalo, akukho sizathu sokwesaba ubhedu lwe-ED kwizicelo ezinamandla.Ngokuchasene noko, lukhetho lwe-de facto kwizicelo zabathengi ezincinci, ezikhaphukhaphu ezifuna iireyithi eziphezulu zomjikelo.Ekuphela kwenkxalabo kulawulo olunyamekileyo apho sisebenzisa "i-additive" plating yenkqubo ye-PTH.I-RA foil iyona kuphela ekhethiweyo ekhoyo yobunzima bobhedu obunzima (ngaphezu kwe-1 oz.) apho usetyenziso olunzima lwangoku kunye nokuguquguquka okuguquguqukayo kuyadingeka.

Ukuqonda iingenelo kunye nokungonakali kwezi zinto zimbini, kubalulekile ukuqonda inzuzo kwiindleko zombini kunye nokusebenza kwezi ntlobo zimbini zefoyile yobhedu kwaye, kubaluleke kakhulu, yintoni ekhoyo ngokurhweba.Umyili kufuneka aqwalasele kungekuphela nje into eza kusebenza, kodwa nokuba inokuthengwa ngexabiso elingayi kutyhala imveliso yokugqibela ngaphandle kwexabiso lemarike.
