Intshayelelo
I-PCB eguquguqukayo luhlobo olulodwa lwe-PCB onokuthi ugobe kwimilo oyifunayo.Ngokuqhelekileyo zisetyenziselwa ukuxinana okuphezulu kunye nokusebenza kobushushu obuphezulu.
Ngenxa yokumelana nobushushu obugqwesileyo, uyilo oluguquguqukayo lufanelekile kumacandelo okufakwa kwe-solder.Ifilimu ye-polyester ecacileyo esetyenziselwa ukwakha i-flex designs isebenza njenge-substrate material.
Ungahlengahlengisa umaleko wobhedu ukusuka ku-0.0001″ ukuya ku-0.010″, ngelixa imathiriyeli yedielectric inokuba phakathi kwe-0.0005″ kunye ne-0.010″ ubukhulu.Uqhagamshelo olumbalwa kuyilo olubhetyebhetye.
Ke ngoko, kukho imidibaniso ethengisiweyo embalwa.Ukongezelela, ezi zijikelezo zithatha kuphela i-10% yendawo yebhodi eqinile
ngenxa yokugoba kwabo bhetyebhetye.
Izinto eziphathekayo
Izinto eziguquguqukayo nezishukumayo zisetyenziselwa ukwenza iiPCB eziguquguqukayo.Ukuguquguquka kwayo kuvumela ukuba iguqulwe okanye ihanjiswe ngaphandle komonakalo ongenakuguqulwa kumacandelo ayo okanye ukudibanisa.
Onke amacandelo e-PCB eguqukayo kufuneka asebenze kunye ukuze asebenze.Uya kufuna izixhobo ezahlukeneyo ukudibanisa ibhodi eguqukayo.
I-Cover Layer Substrate
I-conductor carrier kunye ne-insulating medium inquma umsebenzi we-substrate kunye nefilimu.Ukongezelela, i-substrate kufuneka ikwazi ukugoba kunye nokugoba.
I-Polyimide kunye ne-polyester sheets zisetyenziswa ngokuqhelekileyo kwiisekethe eziguquguqukayo.Ezi zimbalwa zeefilimu ezininzi zepolymer onokuzifumana, kodwa zininzi ezinye onokukhetha kuzo.
Kungcono ukukhetha ngenxa yexabiso eliphantsi kunye ne-substrate ephezulu.
I-PI polyimide yeyona nto isetyenziswa kakhulu ngabavelisi.Olu hlobo lwentlaka ye-thermostatic lunokuxhathisa amaqondo obushushu agqithisileyo.Ngoko ukunyibilika akuyongxaki.Emva kwe-polymerization ye-thermal, igcina i-elasticity kunye nokuguquguquka kwayo.Ukongeza koku, ineempawu ezintle zombane.
Izinto zokuqhuba
Kufuneka ukhethe into yomqhubi ogqithisa amandla ngokufanelekileyo.Phantse zonke iisekethe ezithintela ugqabhuko-dubulo zisebenzisa ubhedu njengoyena mqhubi uphambili.
Ngaphandle kokuba ngumqhubi osebenza kakuhle kakhulu, kulula ukuyifumana.Xa kuthelekiswa nexabiso lezinye izinto zokuqhuba, ubhedu luyinto yokuthengiselana.I-Conductivity akwanele ukukhupha ukushisa ngokufanelekileyo;kufuneka kwakhona ibe ngumqhubi olungileyo we-thermal.Iisekethe eziguquguqukayo zinokwenziwa kusetyenziswa izinto ezinciphisa ubushushu ezibuvelisayo.
Izinto zokuncamathelisa
Kukho i-adhesive phakathi kwephepha le-polyimide kunye nobhedu kuyo nayiphi na ibhodi yesekethe ye-flex.I-epoxy kunye ne-acrylic zezona zincamathelisi zimbini onokuzisebenzisa.
Ukunamathiswa okuqinileyo kuyafuneka ukuphatha ubushushu obuphezulu obuveliswa ngobhedu.
