Kwishishini le-elektroniki elikhawulezayo, ixesha lidla ngokuba ngundoqo xa kuziswa iimveliso ezintsha kwintengiso. I-PCB e-Rigid-flex (iBhodi yeSekethe eShicileleyo) ukuveliswa ngummandla othile apho ukuguqulwa ngokukhawuleza kubaluleke kakhulu. Ukudibanisa iingenelo zePCB eziqinileyo neziguquguqukayo, ezi bhodi zesekethe eziphambili zithandwa ngenxa yokukwazi ukuhlangabezana neemfuno zoyilo oludibeneyo kunye nokumelana neemeko ezirhabaxa zokusingqongileyo.Kweli nqaku, siza kuphonononga izinto ezahlukeneyo ezichaphazela indleko yokwenziwa kwePCBs ekhawulezayo yokujika eqinile.

Ukuphonononga iziseko zee-PCBs eziguquguqukayo:

Phambi kokuntywila kwimiba yeendleko, kubalulekile ukuqonda iipropathi ezisisiseko zee-PCB eziguquguqukayo.

I-PCB eguquguqukayo eqinileluhlobo olukhethekileyo lwebhodi yesekethe edibanisa izinto eziqinileyo kunye neziguquguqukayo ekwakhiweni kwayo. Ziyilwe ngokutshintshanisa iileya eziqinileyo neziguquguqukayo, ezidityaniswe yimizila ye-conductive kunye ne-vias. Le ndibaniselwano yenza i-PCB imelane nokugoba, ukugoba kunye nokujija, ivumela ukubumba okune-dimensional ezintathu kunye nokungena kwizithuba ezincinci okanye ezingaqhelekanga.

Inxalenye engqongqo yebhodi yenziwe kwizinto ze-PCB eziqinileyo ezifana ne-fiberglass (FR-4) okanye i-epoxy edibeneyo. La macandelo abonelela ngenkxaso yesakhiwo, amacandelo ezindlu, kunye neempawu zokudibanisa. Ngakolunye uhlangothi, iindawo eziguquguqukayo zenziwa nge-polyimide okanye izinto ezifanayo eziguquguqukayo ezinokumelana nokugoba ngokuphindaphindiweyo kunye nokugoba ngaphandle kokuphuka okanye ukulahlekelwa ngumsebenzi. Umkhondo conductive kunye vias ezidibanisa umaleko kwi PCB engqongqo-flex nazo bhetyebhetye kwaye zingenziwa ngobhedu okanye ezinye iintsimbi conductive. Zenzelwe ukudala ukudityaniswa kombane okufunekayo phakathi kwamacandelo kunye neengqimba ngelixa zihlalisa i-flex kunye nebhodi.

Xa kuthelekiswa neePCBs zemveli ezingqongqo, iiPCB eziguquguqukayo zineengenelo ezininzi:

Ukuqina: Ukudityaniswa kwezinto eziqinileyo kunye neziguquguqukayo kwenza ii-PCB eziguquguqukayo zichane ngakumbi noxinzelelo lomatshini kunye nokungcangcazela, ukunciphisa umngcipheko womonakalo okanye ukungaphumeleli kwizicelo ezihamba rhoqo okanye ukothuka.
Ukonga isithuba: IiPCB eziguquguqukayo eziguquguqukayo zinokugotywa okanye zigotywe zibe ziimo ezixineneyo, zenze ukusetyenziswa ngokufanelekileyo kwendawo ekhoyo. Oku kunenzuzo ngakumbi kwizicelo apho ubukhulu kunye nobunzima zizinto ezibalulekileyo.
Ukuthembeka: Ukuphelisa izixhumi kunye neentambo kwi-PCB eqinile-flex idizayini kunciphisa inani lamanqaku anokuthi angaphumeleli, ngaloo ndlela kuphuculwe ukuthembeka okupheleleyo. Isakhiwo esidibeneyo sinciphisa umngcipheko wokuphazamiseka komqondiso okanye ukulahleka kokuhanjiswa. Ubunzima obuncitshisiweyo: Ngokuphelisa imfuno yokudibanisa okongeziweyo, iintambo, okanye i-hardware yokunyuka, ii-PCB eziguquguqukayo zinceda ukunciphisa ubunzima obupheleleyo bezixhobo ze-elektroniki, zibenze zilungele i-aerospace, i-automotive, kunye nezicelo eziphathekayo.

Imiba ePhambili echaphazela iNdleko yokuVelisa iFlex eZimeleyo ngokukhawuleza:

Izinto ezininzi zichaphazela iindleko zizonke zokuvelisa iPCB eguqukayo ekhawulezayo eguquguqukayo:
