I-BB enemibala eguquguqukayo ye-BB, eyaziwa njenge Flex PCBIqukethe ifilimu ye-polyimide yokwambathisa kunye nepatheni yesekethe eprintiweyo. Iipolyimides zi-insulators, ke indlela inokugqitywa kuphela xa ipateni yesekethe iqhuba. Kanye “njengesigqumathelo sewelding” se-PCB esiqinileyo, i-PCB eguqukayo igutyungelwe “ngokugubungela” okucekethekileyo okufaka isekethe kuyo nayiphi na uphazamiseko lwe-electromagnetic. I-Flex PCB ngoku ixhaphake kwii-smartphone kunye nokusetyenziswa kwezonyango, ngakumbi xa iisekethe ziphantsi kotshintsho olunamandla lobushushu ngelixa zihlala ziguquguqukayo.

I-PCBS eguqukayo ithathwa njenge “bhetyebhetye” ngenxa yezizathu ezininzi ezahlukeneyo. Eyona nto icace gca kukuba isekethe yabo inokuhlengahlengiswa ukuze ithelekise nemveliso uqobo. Oku kuluncedo ngakumbi xa kuziwa kwiiparameter ezinje ngozinzo, ukuzinza, ubunzima obuphantsi kunye nokuguquguquka. Iibhodi zesekethe zemveli azinakho ukufikelela kumgangatho ofanayo wokuqina, ubuqina kunye nokusebenza ngokukuko.

Iibhodi eziguquguqukayo zingaphezulu kweebhodi ezingqongqo zemveli xa kufikwa kwimida yemveliso. Umzekelo, ukusebenzisa i-PCB eguqukayo endaweni yento eqinileyo kunokunciphisa kakhulu ubungakanani bemveliso. Ziyakwazi ukugoba kunye nokutshintshela ukulungelelanisa imveliso engundoqo. Imveliso iyonke ingenziwa ikhaphukhaphu isebenzisa izinto ezifanayo njengamacandelo angqingqwa kwaye anzima. However, flexible plates are not completely flexible. Ezi PCBS zinendawo ezithile eziqinileyo, kodwa isekethe ikakhulu ibekwe kwiindawo eziguqukayo, ke inokuhlengahlengiswa ngokwemveliso. Gcina iinxalenye eziqinileyo ezisetyenziselwa ukuxhasa izinto eziphathekayo ukuze igcinwe kwelona nqanaba lisezantsi.

1. Ukwakhiwa:

I-PCB eguqukayo enokuhambelana nokuqina kwayo inokwakhiwa ngeendlela ezahlukeneyo. Ngokwetekhnoloji, inqanaba kunye nezinto eziphathekayo, sizihlela ngolu hlobo lulandelayo:

Isekethe eguquguqukayo enamacala amabini (i-SSFC) inolungelelwaniso olunye oluqukethe isinyithi okanye isinyithi esigcwele isinyithi kwifilimu eguqukayo ye-dielectric; Ngokwesiqhelo i-polyimide isebenzisa i-THT (nge-hole-hole) indlela yokunyusa icandelo, oko kuthetha ukuba ungasebenzisa icala elinye ukulungisa kunye nokutshintsha icandelo. I-PCB emacaleni ibhetyebhetye kunye okanye ngaphandle kokuthintela ukombiwa kunokwenziwa kusetyenziswa ifilimu yokwambathisa; Nangona kunjalo, ukusetyenziswa kwesambatho sokukhusela kwisekethe yeyona nto ixhaphakileyo kuba kuthintela isekethe kunye nayiphi na i-EMI. The structure and insulation of a single-layer flexible PCB are explained as follows:

Umzobo we-PCB eguqulweyo yi-subset enomtsalane ye-PCB eguqukayo, uyilo lwangoku lubhekisa kwindlela ethile eguqukayo yokuvelisa evelisa isekethe eguqukayo kunye nabaqhubi bezobhedu bobukhulu obahlukeneyo ngobude bayo. The conductor is thinner in the flexible region and thicker in the rigid region. This method involves selective etching of copper foil to obtain depth in various areas of the circuit.

Ukukrola ubuchwephesha be-PCB ekhethiweyo bahlala bekhethwa ukuvelisa oonxibelelwano bezinyithi ezingenanto ukwenza oku kwenzeke. Yandiswa ukusuka kumda ukuya kwi-plug-in yokuxhuma. Indawo eyandisiweyo yenza ukuba amalungu adibeneyo azinze kwaye ahlale ixesha elide kuneesekethe eziqhelekileyo eziguquguqukayo.

I-PCB eguquguqukayo ye-Multilayer inesekethe efanayo eguqukayo enemigca emininzi. Olu luhlu luxhunyiwe ngamacwecwe acabalele. Imaleko PCB multi-maleko bhetyebhetye gqolo ngaplastiki ngemingxuma. Ezi zi-PCBS ze-multilayer ziyafana ne-PCBS eziqinileyo ngaphandle kokuhluka kwezinto, umgangatho, iimpawu kunye nexabiso. Imijikelezo emininzi eguqukayo yemijikelezo ibiza kakhulu kunabalingane bayo, kodwa iqinisekise umgangatho ongcono. Apha ngezantsi kukho umbono wePCB eyahlukeneyo.

Elona candelo lingqongqo yinxalenye esetyenziselwa ukujoyina. Elinye ibhodi yesekethe iyaguquguquka.

2. isicelo:

I-PCBS eguqukayo isetyenziswa kwezi ndawo zilandelayo:

Iibhodi zesekethe eziprintiweyo eziguqukayo zihlala zisetyenziswa xa kufuneka ukuthembeka, ukulungeleka kunye neemveliso ezingasindi, njengoko kunjalo kwizixhobo zonyango. Ipilisi yokugwinya yekhamera ebizwa ngokuba yiPilisi Cam isebenzisa isekethe ecekeceke kakhulu ekufuneka igqunyiwe ngokufanelekileyo kwaye yomelele. Emva kokuginya ipilisi, oogqirha kunye neengcali banokujonga ngokuchanekileyo izicubu ngaphakathi komzimba. Iipilisi kufuneka zincinci kakhulu kwaye kufuneka zihambe ngokuguquguqukayo emzimbeni, ngenxa yoko ii-PCBS eziguqukayo lukhetho olufanelekileyo, ngokungafaniyo nezingqongqo kunye nebrittle.

B) Iifowuni eziphathwayo:

Imfuno yeefowuni “ezikrelekrele” zifuna izixhobo eziphathwayo ukuba zenziwe ngamacandelo amancinci kunye neesekethe eziguqukayo. Ke, iiPCBS eziguqukayo zidlala indima ebalulekileyo kwimijikelezo esetyenziswa kwezinye iindawo ezibalulekileyo zesekethe, ezinje nge “amplifiers power”. Ke iifowuni zinokuba zilumkile kwaye zingasindi.

C) Izixhobo zeKhompyutha:

Iimveliso zombane kwibhodi yomama sisiseko kunye nomphefumlo wekhompyuter yanamhlanje. Uyilo lweesekethe kufuneka lwenziwe ngendlela encinci, emfutshane. Ke ngoko, iibhodi zesekethe eziguqukayo zisetyenziselwa ukugcina yonke into izinzile kwaye incinci.
