Amasekhethi aguquguqukayo, awaziwa nangokuthi amabhodi esekethe aphrintiwe (ama-PCB), ayizingxenye ezibalulekile zemishini eminingi kagesi yanamuhla. Ukuguquguquka kwazo kuzivumela ukuthi zivumelane nezimo nosayizi abahlukene, kuzenze zilungele izinhlelo zokusebenza ezidinga izinga elithile lokugoba noma ukugoba. Ukwakhiwa kwama-flex circuits kuhilela izinyathelo eziningana, kuhlanganise nokukhethwa kwezinto ezifanele.Kulokhu okuthunyelwe kwebhulogi, sizohlola izinto ezijwayelekile ezisetshenziswa ekwenziweni kwesekethe eguquguqukayo kanye nendima eziyidlalayo ekuqinisekiseni ukuqina nokusebenza kwalawa masekethi.
Enye yezinto eziyinhloko ezisetshenziswa ekukhiqizeni i-flex circuit i-polyimide. I-Polyimide iyimpahla yepulasitiki ekwazi ukumelana nokushisa okuphezulu engamelana nezindawo ezinokhahlo.Inokusimama okuhle kakhulu kwe-thermal kanye nezakhiwo zokuvikela ugesi, okuyenza ifanelekele ukusetshenziswa kumasekhethi aguquguqukayo angase abekwe emazingeni okushisa aphezulu noma izimo ezimbi kakhulu. I-Polyimide ivamise ukusetshenziswa njengento eyisisekelo noma i-substrate yamasekethe aguquguqukayo.
Enye impahla evame ukusetshenziswa ekukhiqizeni i-flex circuit ithusi.I-Copper iyi-conductor kagesi enhle kakhulu, iyenza ilungele ukudlulisa amasignali kagesi kumasekhethi aguqukayo. Ngokuvamile i-laminated ku-polyimide substrate ukuze yenze iminonjana eqhubayo noma izintambo kusekethe. I-foil yethusi noma amashidi ethusi amancane avame ukusetshenziswa enkambweni yokukhiqiza. Ubukhulu bengqimba yethusi bungahluka ngokuya ngezidingo ezithile zohlelo lokusebenza.
Izinto zokunamathisela nazo zibalulekile ekwenziweni kwesekethe ye-flex.Ama-Adhesive asetshenziselwa ukuhlanganisa izingqimba ezihlukene zesekethe eguquguqukayo ndawonye, ukuqinisekisa ukuthi isifunda sihlala sinjalo futhi sivumelana nezimo. Izinto ezimbili zokunamathela ezijwayelekile ezisetshenziswa ekwenziweni kwesekethe eguquguqukayo yizinamathiselo ezisuselwa ku-acrylic nezinamatheliso ezisuselwa ku-epoxy. Izinamathiselo ezisekelwe ku-Acrylic zinikeza ukuguquguquka okuhle, kuyilapho izinamathiselo ezisekelwe epoxy ziqinile futhi zihlala isikhathi eside.
Ngaphezu kwalezi zinto zokwenziwa, izinto zokumboza noma imaski ye-solder zisetshenziselwa ukuvikela imikhondo ye-conductive ku-flex circuit.Izinto zokumbondelana ngokuvamile zenziwe nge-polyimide noma imaski ye-solder yezithombe eziwuketshezi (LPI). Asetshenziswa emithonjeni ye-conductive ukuze ahlinzeke ngokufakelwa futhi avikeleke ezintweni zemvelo ezifana nomswakama, uthuli namakhemikhali. Isendlalelo sekhava futhi sisiza ukuvimbela izifunda ezimfushane futhi sithuthukise ukwethembeka okuphelele kwe-flex circuit.
Enye into evame ukusetshenziswa ekukhiqizeni i-flex circuit izimbambo.Izimbambo zivame ukwenziwa nge-FR-4, i-fiberglass epoxy impahla ebuyisela ilangabi. Zisetshenziselwa ukuqinisa izindawo ezithile ze-flex circuit ezidinga ukwesekwa okwengeziwe noma ukuqina. Izimbambo zingangezwa ezindaweni lapho izixhumi noma izingxenye zifakwe khona ukuze zinikeze amandla engeziwe nokuzinza kumjikelezo.
Ngaphezu kwalezi zinto eziyinhloko, ezinye izakhi ezinjengama-solder, ama-coatings okuvikela, nezinto zokuvikela zingasetshenziswa ngesikhathi sokukhiqiza isifunda se-flex.Ngayinye yalezi zinto ezisetshenziswayo idlala indima ebalulekile ekuqinisekiseni ukusebenza, ukuqina nokuthembeka kwamasekhethi aguquguqukayo ekusetshenzisweni okuhlukahlukene.
Kafushane, izinto ezivame ukusetshenziswa ekwenziweni kwesekethe eguquguqukayo zifaka i-polyimide njenge-substrate, ithusi njenge-conductive traces, into enamathelayo yokubopha, izendlalelo zokumboza zokuvikela nokuvikela, nezimbambo zokuqinisa.Ngayinye yalezi zinto zisebenzisa inhloso ethile futhi ndawonye zithuthukisa ukusebenza nokuthembeka kwamasekhethi aguqukayo. Ukuqonda nokukhetha izinto ezifanele kubalulekile ekukhiqizeni amasekhethi ekhwalithi ephezulu avumelana nezimo ezihlangabezana nezidingo eziqinile zemishini yesimanje kagesi.
