Iisekethe eziguquguqukayo, ezikwaziwa ngokuba ziibhodi zesekethe eziguquguqukayo (iiPCBs), ziyinxalenye ebalulekileyo yezixhobo ezininzi zombane zanamhlanje.Ukuba bhetyebhetye kwabo kubavumela ukuba baziqhelanise neemilo kunye nobukhulu obahlukeneyo, okubenza ukuba balungele usetyenziso olufuna inqanaba elithile lokugoba okanye ukugoba.Ukwenziwa kweesekethe ze-flexible kubandakanya amanyathelo amaninzi, kubandakanywa nokukhethwa kwezinto ezifanelekileyo.Kule post yebhlog, siza kuphonononga izixhobo eziqhelekileyo ezisetyenziswa kulwakhiwo lwesekethe eguqukayo kunye nendima abayidlalayo ekuqinisekiseni ukuqina kunye nokusebenza kwezi sekethe.
Enye yezinto eziphambili ezisetyenziselwa ukuvelisa i-flex circuit yi-polyimide.I-Polyimide sisixhobo seplastiki esimelana nobushushu obuphezulu obunokumelana nemekobume erhabaxa.Inozinzo oluhle kakhulu lwe-thermal kunye neempawu zokukhusela umbane, okwenza ukuba zilungele ukusetyenziswa kwiisekethe eziguquguqukayo ezinokubonakala kubushushu obuphezulu okanye iimeko ezigqithisileyo.I-Polyimide isetyenziswa ngokuqhelekileyo njengento esisiseko okanye i-substrate yeesekethe eziguquguqukayo.
Enye into esetyenziswa ngokuqhelekileyo kwimveliso yesekethe ye-flex yobhedu.I-Copper yi-conductor egqwesileyo yombane, iyenza ilungele ukuhambisa imiqondiso yombane kwiisekethe eziguqukayo.Ngokuqhelekileyo i-laminated kwi-substrate ye-polyimide ukwenza i-conductive traces okanye i-wiring kwisekethe.I-foil yobhedu okanye amaphepha obhedu amancinci ahlala esetyenziswa kwinkqubo yokuvelisa.Ubunzima bomgangatho wobhedu bunokwahluka ngokweemfuno ezithile zesicelo.
Izinto ezincamathelayo nazo zibalulekile kwimveliso yesekethe ye-flex.I-Adhesives isetyenziselwa ukudibanisa iileyile ezahlukeneyo zesekethe ye-flex kunye, ukuqinisekisa ukuba isiphaluka sihlala silungile kwaye siguquguquka.Izinto ezimbini eziqhelekileyo zokuncamathelisa ezisetyenziswa kwimveliso yesekethe eguqukayo zizincamathelisi ezisekwe kwi-acrylic kunye ne-epoxy-based adhesives.I-adhesives esekelwe kwi-Acrylic inika ukuguquguquka okulungileyo, ngelixa i-epoxy-based adhesives iqinile kwaye iqinile.
Ukongeza kwezi zixhobo, ii-coverlays okanye izixhobo ze-mask ze-solder zisetyenziselwa ukukhusela i-conductive traces kwi-flex circuit.Izixhobo zokwaleka ngokwesiqhelo zenziwe nge-polyimide okanye imaski ye-solder ye-photoimaging engamanzi (LPI).Zisetyenziswa kwiindlela zokuqhuba ukubonelela nge-insulation kunye nokukhusela kwizinto ezisingqongileyo ezifana nokufuma, uthuli kunye neekhemikhali.Uluhlu lwekhava lukwanceda ukukhusela iisekethe ezimfutshane kunye nokuphucula ukuthembeka okupheleleyo kwesekethe ye-flex.
Enye into esetyenziswa ngokuqhelekileyo kwimveliso yesekethe ye-flex iimbambo.Iimbambo zidla ngokwenziwa nge-FR-4, i-fiberglass eretardant idangatye imathiriyeli epoxy.Zisetyenziselwa ukuqinisa iindawo ezithile zesekethe ye-flex efuna inkxaso eyongezelelweyo okanye ukuqina.Iimbambo zinokudibaniswa kwiindawo apho iziqhagamshelo okanye amacandelo afakwe khona ukunika amandla okongeziweyo kunye nokuzinza kwisekethe.
Ukongeza kwezi zixhobo eziphambili, amanye amacandelo afana nee-solders, iingubo zokukhusela, kunye nezixhobo zokukhusela zingasetyenziselwa ngexesha lokuvelisa isekethe ye-flex.Ngasinye sezi zixhobo zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza, ukuqina kunye nokuthembeka kweesekethe eziguquguqukayo kwizicelo ezahlukeneyo.
Isishwankathelo, izinto ezisetyenziswa ngokuqhelekileyo kwi-flexible circuit fabrication ziquka i-polyimide njenge-substrate, i-copper njenge-conductive traces, i-adhesive material for bonding, i-cover layers ye-insulation kunye nokukhusela, kunye neembambo zokuqinisa.Nganye kwezi zixhobo zisebenza ngenjongo ethile kwaye kunye kunye nokuphucula ukusebenza kunye nokuthembeka kweesekethe ze-flex.Ukuqonda kunye nokukhetha izixhobo ezifanelekileyo kubalulekile ekuveliseni umgangatho ophezulu weesekethe eziguquguqukayo ezihlangabezana neemfuno ezingqongqo zezixhobo zombane zanamhlanje.
