The flexible P-colored BB, eo ka tloaelo e tsejoang e le Flex PCB, e na le filimi ea polyimide e sireletsang le mokhoa oa potoloho o hatisitsoeng. Polyimide ke li-insulators, kahoo tsela e ka phethoa feela haeba mokhoa oa potoloho o tsamaisa. Joalo ka “mask ea ho cheselletsa” ea PCB e thata, PCB e tenyetsehang e koahetsoe ka “mokokotlo” o mosesaane o sirelletsang potoloho ho tsoa tšitiso efe kapa efe ea motlakase. Flex PCB joale e se e tloaelehile ho li-smartphone le lits’ebetso tsa bongaka, haholo ha lipotoloho li ba le liphetoho tse matla tsa mocheso ha li ntse li fetoha le maemo.

PCBS e tenyetsehang e nkuoa e le “e tenyetsehang” ka mabaka a mangata a fapaneng. Ntho e totobetseng ka ho fetisisa ke hore potoloho ea bona e ka fetoloa hore e lumellane le sehlahisoa ka boeona. Sena se thusa haholo ha ho tluoa litekanyetsong tse kang ho tsitsa, ho tšoarella, boima bo tlase le ho tenyetseha. Liboto tsa setso tsa potoloho li ke ke tsa fihlela maemo a ts’oanang a ho tšoarella, ho tiea le ho sebetsa hantle.

Liboto tse feto-fetohang li phahametse mapolanka a tloaelehileng a thata ha ho tluoa tabeng ea mefokolo ea lihlahisoa. Mohlala, ho sebelisa PCB e tenyetsehang ho fapana le e thata ho ka fokotsa boholo ba sehlahisoa haholo. Li ka kobeha le ho phetloa ho ikamahanya le sehlahisoa sa mantlha. Sehlahisoa sohle se ka etsoa hore se be bobebe ho sebelisa likarolo tse tšoanang le likarolo tse thata le tse boima. However, flexible plates are not completely flexible. Li-PCBS tsena li na le libaka tse thata, empa potoloho e behiloe haholo likarolong tse tenyetsehang, kahoo e ka fetoloa ho latela sehlahisoa. Boloka likarolo tse thata tse sebelisetsoang tšehetso ea lintho tse bonahalang hore li bolokoe boemong bo tlase haholo.

1. Kaho:

PCB e tenyetsehang e ka lumellanang le ho tiea ha eona e ka hahuoa ka mekhoa e mengata e fapaneng. Ho latela mahlale, boemo le thepa, re li arola ka tsela e latelang:

Single-sided flexible circuit (SSFC) consists of a single conductive layer consisting of a metal or metal-filled polymer on a flexible dielectric film; Ka tloaelo polyimide e sebelisa mokhoa oa THT (through-hole) ho kenya karolo, ho bolelang hore o ka sebelisa lehlakore le le leng ho lokisa le ho fetola karolo. PCB e tenyetsehang ka lehlakore le le leng e nang le kapa ntle le tšireletso e ka etsoa ho sebelisoa filimi e sireletsang; Leha ho le joalo, ts’ebeliso ea tšireletso e sireletsang potolohong ke mokhoa o tloaelehileng haholo hobane o thibela potoloho le EMI efe kapa efe. The structure and insulation of a single-layer flexible PCB are explained as follows:

Sculpted flexible PCB is an attractive subset of flexible PCB, the present invention relates to a particular flexible manufacturing method that produces a flexible circuit with copper conductors of varying thickness along its length. 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.

Mekhoa ea ho ngola e tenyetsehang ea PCB hangata e khethoa ho hlahisa likhokahano tse se nang letho tsa tšepe ho etsa hore sena se khonehe. E atoloha ho tloha bohale ho isa khokahanong ea plug-in. The increased area makes the solder joints more stable and durable than ordinary flexible circuits.

Multilayer tenyetsehang PCB na le e tšoanang tenyetsehang oa potoloho le le dikarolo tse ngata. Lisebelisoa tsena li kopantsoe ke lipoleiti tse bataletseng. Likarolo tsa PCB tse ngata tse tenyetsehang li lula li entsoe ka likoti. These multilayer PCBS are similar to rigid multilayer PCBS except for variations in material, quality, characteristics, and cost. Li-circuits tsa multilayer flexible li theko e boima ho feta balekane ba tsona, empa li netefatsa boleng bo ntlafetseng. Ka tlase ke pono ea PCB e nang le mekato e mengata.

Karolo feela e thata ke karolo e sebelisetsoang ho kenela. Tse ling kaofela tsa boto ea potoloho lia fetoha.

2. e sebetsa joang:

PCBS e tenyetsehang e sebelisoa libakeng tse latelang:

Hangata liboto tsa potoloho tse hatisitsoeng li sebelisoa ha ho tšepahala, ho ikamahanya le maemo le lihlahisoa tse bobebe ho hlokahala, joalo ka tabeng ea lisebelisoa tsa bongaka. Pilisi ea kh’amera e metsang e bitsoang Pill Cam e sebelisa potoloho e tšesaane haholo e tlamehang ho koaheloa hantle le ho tšoarella hantle. Ka mor’a ho koenya pilisi, lingaka le litsebi li khona ho sheba ka nepo lesela le tsoang ka har’a ‘mele. Lipilisi li hloka ho ba nyane haholo ‘me li tlameha ho tsamaea habonolo’ meleng, kahoo li-PCBS tse tenyetsehang ke khetho e ntle, ho fapana le tse thata le tse bobebe.

B) Mehala e bohlale:

Tlhokahalo ea lifono tse “bohlale” e hloka hore lisebelisoa tsa mohala li entsoe ka likaroloana tse nyane le lisekete tse tenyetsehang. Kahoo, li-PCBS tse tenyetsehang li bapala karolo ea bohlokoa lipotolohong tse sebelisoang likarolong tse ling tsa bohlokoa tsa potoloho, joalo ka “li-amplifiers tsa motlakase”. Mehala e ka ba bohlale ebile e bobebe.

C) Lisebelisoa tsa Khomphutha:

Lihlahisoa tsa elektroniki tse lebopeng la ‘m’a tsona ke mantlha le moea oa komporo ea sejoale-joale. Moralo oa potoloho o lokela ho kengoa tšebetsong ka mokhoa o monyane, o mokhuts’oane. Ka hona, liboto tsa potoloho tse tenyetsehang li sebelisoa ho boloka tsohle li tsitsitse ebile li le nyane.
