Uyilo olungqongqo lwePcb lubonelela ngenkqubo eyodwa kunye neguquguqukayo edibanisa iingenelo zePCB eziqinileyo kunye neziguquguqukayo. Olu yilo luyilayo lunikeza ukuguquguquka okuphuculweyo ngelixa ugcina ingqibelelo yolwakhiwo efumaneka kwiiPCB eziqinileyo. Ukuze udale iibhodi zeesekethe eziprintiweyo ezisebenzayo kunye nezizinzileyo, izinto ezithile zisetyenziselwa inkqubo yokuvelisa. Ukuqhelana nezi zixhobo kubalulekile kubavelisi kunye neenjineli ezifuna ukuthatha inzuzo yee-PCBs eziguquguqukayo. Ngokuphonononga izinto ezibandakanyekayo, umntu unokuqonda ngcono imisebenzi kunye nokusetyenziswa okunokwenzeka kwezi bhodi zesekethe eziphambili.

I-Copper Foil:

I-foil yobhedu yinto ephambili kwi-rigid-flex production. Eli phepha elicekethekileyo lobhedu yeyona nto iphambili eyenza i

iindlela zokuqhuba ezifunekayo ukuze ibhodi isebenze ngokufanelekileyo.

Esinye sezizathu eziphambili zobhedu olukhethwayo kule njongo kukuhamba kombane okugqwesileyo. I-Copper yenye yezona zinto zihamba phambili kwiintsimbi, ezivumela ukuba zithwale ngokufanelekileyo umbane ngokuhamba kwiindlela zesekethe. Le conductivity ephezulu iqinisekisa ilahleko encinci yesignali kunye nokusebenza okuthembekileyo kwiiPCB eziguquguqukayo. Ukongezelela, i-foil yobhedu inokumelana nokushisa okuphawulekayo. Olu phawu lubalulekile kuba iiPCB zihlala zivelisa ubushushu ngexesha lokusebenza, ngakumbi kwizicelo ezisebenza kakhulu. I-Copper inamandla okumelana nokushisa okuphezulu, okukulungele ukutshabalalisa ukushisa kunye nokukhusela ibhodi ekushiseni. Ukuze kufakwe i-foil yobhedu kwisakhiwo se-PCB esiqinileyo, ngokuqhelekileyo i-laminated kwi-substrate njenge-conductive layer. Inkqubo yokuvelisa ibandakanya ukudibanisa i-foil yobhedu kwi-substrate material usebenzisa i-adhesives okanye i-glues efakwe ukushisa. I-foil yobhedu iye ifakwe ukwenza ipateni yesekethe efunekayo, yenza iindlela zokuqhuba ezifunekayo ukuze ibhodi isebenze ngokufanelekileyo.

Inkqutyana yezinto eziphathekayo:

I-substrate material yinxalenye ebalulekileyo ye-PCB eqinile-flex kuba inika inkxaso yesakhiwo kunye nokuzinza kwibhodi. Izinto ezimbini ze-substrate eziqhelekileyo ezisetyenziswa kwi-rigid-flex PCB yokuvelisa i-polyimide kunye ne-FR-4.

I-Polyimide substrates ziyaziwa ngokugqwesa kweempawu zokushisa kunye nezomatshini. Banobushushu obuphezulu beglasi yokutshintsha, ngokuqhelekileyo malunga ne-260 ° C, oku kuthetha ukuba banokumelana namaqondo aphezulu ngaphandle kokulahlekelwa yimfezeko yesakhiwo. Oku kwenza i-polyimide substrates ilungele iindawo eziguquguqukayo zePCB kuba zinokugoba kwaye zigobe ngaphandle kokwaphuka okanye ukuthoba.

I-Polyimide substrates zikwanazo nozinzo olululo lwe-dimensional, nto leyo ethetha ukuba zigcina imilo kunye nobukhulu bazo naxa zisesichengeni sokutshintsha kweqondo lobushushu kunye neemeko zokufuma. Olu uzinzo lubalulekile ekuqinisekiseni ukuchaneka nokuthembeka kwePCB.
Ukongeza, i-polyimide substrates inokumelana nekhemikhali ebalaseleyo. Ukuxhathisa kwabo kuluhlu olubanzi lweekhemikhali, kuquka i-solvents kunye ne-acids, inceda ukuqinisekisa ixesha elide kunye nokuqina kwe-PCB. Oku kubenza bafanelekele izicelo apho iibhodi zeesekethe zinokuthi zivelele kwiindawo ezinobunzima okanye izinto ezinobungozi.

Ngokwahlukileyo koko, ii-substrates ze-FR-4 zilukwe kwimicu yeglasi eyomelezwe yi-epoxy. Iqinile kwaye izinzile, ezi zixhobo zifanelekile kwiindawo eziqinileyo zeesekethe eziprintiweyo eziqinileyo. Ukudityaniswa kwe-fiberglass kunye ne-epoxy kudala i-substrate eyomeleleyo kwaye ehlala ixesha elide enokumelana nokutshintsha kobushushu obuphezulu ngaphandle kokuphazamiseka okanye ukuqhekeka. Oku kuzinza kwe-thermal kubalulekile kwizicelo ezibandakanya amacandelo ombane aphezulu avelisa ubushushu obuninzi.

Isibophelelo:

I-epoxy adhesives isetyenziswa ngokubanzi kwi-rigid-flex board production ngenxa yesakhono sazo esinamandla sokubambisana kunye nokumelana nobushushu obuphezulu. Izincamathelisi ze-epoxy zenza ibhondi ehlala ixesha elide kwaye eqinile enokumelana neemeko ezirhabaxa zokusingqongileyo, izenze zilungele usetyenziso olufuna iindibano zePCB ezinamandla nezihlala ixesha elide. Baneempawu ezibalaseleyo zoomatshini, kubandakanywa amandla aphezulu kunye nokumelana nempembelelo, ukuqinisekisa ingqibelelo yePCB naphantsi koxinzelelo olugqithisileyo.

I-epoxy adhesives nayo inokumelana nekhemikhali ebalaseleyo, izenza zilungele ukusetyenziswa kwiibhodi zesekethe eziguquguqukayo eziprintiweyo ezinokudibana neekhemikhali ezahlukeneyo okanye izinyibilikisi. Baxhathisa ukufuma, ioli, kunye nezinye izinto ezingcolisayo, ziqinisekisa ixesha elide le-PCB kunye nokuthembeka.

I-adhesives ye-Acrylic, ngakolunye uhlangothi, iyaziwa ngokuguquguquka kunye nokuchasana nokungcangcazela. Banamandla asezantsi ebhondi kuneepoxy ezincamathelayo, kodwa babe nokuguquguquka okuhle, okuvumela iPCB ukuba iguquke ngaphandle kokubeka esichengeni ibhondi. Izincamathelisi ze-Acrylic nazo zinokuxhathisa okuhle kokungcangcazela, zizenza zilungele usetyenziso apho iPCB inokubekwa phantsi kwentshukumo eqhubekayo okanye uxinzelelo lomatshini.

Ukukhethwa kwe-epoxy kunye ne-adhesive ye-acrylic kuxhomekeke kwiimfuno ezithile ze-rigid flex circuits application. I-epoxy adhesives yinto yokuqala yokukhetha ukuba ibhodi yesiphaluka idinga ukujamelana nokushisa okuphezulu, iikhemikhali ezinobunzima, kunye neemeko ezinzima zendalo.Ngakolunye uhlangothi, ukuba ukuguquguquka kunye nokuxhatshazwa kwe-vibration kubalulekile, i-adhesive ye-acrylic yinto engcono kakhulu.

Kubalulekile ukukhetha ngononophelo i-adhesive ngokweemfuno ezithile ze-PCB ukuze kuqinisekiswe ibhondi eyomeleleyo kwaye ezinzileyo phakathi kwamaleko ahlukeneyo. Izinto ezifana nobushushu, ukuguquguquka, ukuxhathisa imichiza, kunye neemeko zokusingqongileyo kufuneka ziqwalaselwe xa ukhetha i-adhesive efanelekileyo.

Ukhuseleko:

Ukwaleka yinxalenye ebalulekileyo yebhodi yesekethe eprintiweyo (PCB) njengoko ikhusela umphezulu wePCB kwaye iqinisekisa ubomi bayo obude. Iindidi ezimbini eziqhelekileyo zokwaleka zisetyenziswa kwi-PCB yokwenziwa: izigqubuthelo ze-polyimide kunye ne-liquid solder mask solder mask (LPSM) umaleko.

Ukwaleka kwePolyimide kujongwa kakhulu ngenxa yokuguquguquka okugqwesileyo kunye nokumelana nobushushu. Olu lwalekayo lufaneleke ngokukodwa iindawo zePCB ezifuna ukugotshwa okanye ukugotshwa, njengeePCB eziguquguqukayo okanye izicelo ezibandakanya intshukumo ephindaphindwayo. Ukuguquguquka kwesigqubuthelo se-polyimide kuqinisekisa ukuba i-flex flex printed circuits inokumelana noxinzelelo lomatshini ngaphandle kokuphazamisa ingqibelelo yayo. Ukongezelela, ukugqithiswa kwe-polyimide kunokumelana ne-thermal egqwesileyo, evumela ukuba ikwazi ukumelana namaqondo okushisa aphezulu ngaphandle kwefuthe elibi ekusebenzeni okanye kubomi bebhodi ye-flexible eqinile.

Kwelinye icala, ii-LPSM ezingaphezulu zidla ngokusetyenziswa kwiindawo eziqinileyo zePCB. Ezi zigqubuthelo zibonelela ngokugqwesileyo kokugquma kunye nokukhuselwa kwizinto ezisingqongileyo ezifana nokufuma, uthuli kunye neekhemikhali. Ukwaleka kwe-LPSM kusebenza ngokukodwa ekuthinteleni i-solder paste okanye i-flux ekusasazeni kwiindawo ezingafunekiyo kwi-PCB, ukuqinisekisa ukwahlula okufanelekileyo kombane kunye nokuthintela imijikelezo emfutshane. Iipropati ezigqumayo ze-LPSM zokwaleka ziphucula ukusebenza ngokubanzi kunye nokuthembeka kwe-flex rigid pcb.

I-Polyimide kunye ne-LPSM ii-overlays zidlala indima ebalulekileyo ekugcineni ukusebenza kunye nokuqina kwebhodi yesekethe eguquguqukayo eqinile. Ukukhetha okufanelekileyo kokwaleka kuxhomekeke kwiimfuno ezithile zoyilo lwePCB, kuquka nesicelo esicetywayo, iimeko zokusebenza, kunye neqondo lokubhetyebhetye olufunekayo. Ngokukhetha ngononophelo imathiriyeli yokugquma eyiyo, abavelisi be-PCB banokuqinisekisa ukuba umphezulu we-PCB ukhuselwe ngokufanelekileyo, ukwandisa ubomi bayo kunye nokuphucula ukusebenza kwayo ngokubanzi.

Isishwankathelo:

Ukukhetha izinto eziphathekayo kwiRigid Flex Pcb Fabrication ibalulekile ekuqinisekiseni impumelelo yezi bhodi zesekethe eziphambili. I-foil yobhedu inika i-conductivity egqwesileyo yombane, ngelixa i-substrate inika isiseko esiqinileyo sesekethe. I-Adhesives kunye ne-overlays zikhusela kwaye zifake i-insulate amacandelo ukwenzela ukuqina kunye nokusebenza. Ngokuqonda iipropathi kunye neenzuzo zezi zixhobo, abavelisi kunye neenjineli banokuyila kwaye bavelise iiPCB ezikumgangatho ophezulu eziqinileyo ezihlangabezana neemfuno ezizodwa zezicelo ezahlukeneyo. Ukudibanisa ulwazi kwinkqubo yokuvelisa kunokudala izixhobo ze-elektroniki ezinqamlekileyo ezinokuguquguquka okukhulu, ukuthembeka kunye nokusebenza kakuhle. Njengoko itekhnoloji iqhubeka nokuhambela phambili, imfuno yeePCBs eziguquguqukayo ziya kukhula kuphela, ke kuyafuneka ukuba uhlale usazi kuphuhliso lwamva nje lwemathiriyeli kunye nobuchule bokwenza.
