Li-circuits tse feto-fetohang, tse tsejoang hape e le liboto tsa potoloho tse hatisitsoeng (PCBs), ke likarolo tsa bohlokoa tsa lisebelisoa tse ngata tsa kajeno tsa elektroniki. Ho tenyetseha ha tsona ho li lumella ho ikamahanya le libopeho le boholo bo fapaneng, ho etsa hore e be tse loketseng lits'ebetso tse hlokang ho kobeha kapa ho kobeha. Ho etsoa ha li-circuits tsa flex ho kenyelletsa mehato e mengata, ho kenyelletsa le khetho ea lisebelisoa tse loketseng.Ka poso ena ea blog, re tla hlahloba lisebelisoa tse tloaelehileng tse sebelisoang ho etsa flex circuit le karolo eo li e bapalang ho netefatsa ho tšoarella le ho sebetsa ha lipotoloho tsena.
E 'ngoe ea lisebelisoa tsa mantlha tse sebelisoang tlhahisong ea potoloho ea flex ke polyimide. Polyimide ke thepa ea polasetiki e hanyetsanang le mocheso o phahameng e ka mamellang maemo a thata.E na le botsitso bo botle ba mocheso le thepa ea ho thibela motlakase, e etsang hore e loketse ho sebelisoa lipotolohong tse tenyetsehang tse ka 'nang tsa pepesehela mocheso o phahameng kapa maemo a feteletseng. Polyimide hangata e sebelisoa e le thepa ea motheo kapa substrate bakeng sa lipotoloho tse tenyetsehang.
Ntho e 'ngoe e atisang ho sebelisoa ha ho etsoa flex circuit ke koporo.Copper ke conductor e ntle haholo ea motlakase, e etsang hore e be se loketseng bakeng sa ho fetisa mats'oao a motlakase lipotolohong tse feto-fetohang. Hangata e na le laminated ho substrate ea polyimide ho etsa litsela tse tsamaisang kapa lithapo holim'a potoloho. Hangata foil ea koporo kapa maqephe a masesaane a koporo a sebelisoa ha ho etsoa tlhahiso. Botenya ba lera la koporo bo ka fapana ho ea ka litlhoko tse khethehileng tsa kopo.
Lisebelisoa tse khomarelang le tsona li bohlokoa haholo tlhahisong ea potoloho ea flex.Likhomaretsi li sebelisetsoa ho kopanya likarolo tse fapaneng tsa potoloho e feto-fetohang hammoho, ho netefatsa hore potoloho e lula e tiile ebile e tenyetseha. Lisebelisoa tse peli tse tloaelehileng tsa sekhomaretsi tse sebelisoang tlhahisong ea potoloho ea flex ke likhomaretsi tse thehiloeng ho acrylic le li-adhesives tse thehiloeng ho epoxy. Likhomaretsi tse thehiloeng ho Acrylic li fana ka maemo a bonolo, ha li-adhesives tse thehiloeng ho epoxy li thata ebile li tšoarella.
Ntle le lisebelisoa tsena, li-coverlay kapa lisebelisoa tsa mask a solder li sebelisoa ho sireletsa mesaletsa ea conductive ho potoloho ea flex.Lisebelisoa tse koaheletsoeng hangata li entsoe ka polyimide kapa liquid photoimaging solder mask (LPI). Li sebelisoa mekhoeng ea conductive ho fana ka insulation le ho li sireletsa linthong tsa tikoloho joalo ka mongobo, lerōle le lik'hemik'hale. Sekoahelo sa sekoahelo se boetse se thusa ho thibela lipotoloho tse khutšoanyane le ho ntlafatsa botšepehi ba kakaretso ba potoloho ea flex.
Ntho e 'ngoe e atisang ho sebelisoa ha ho etsoa flex circuit ke likhopo.Hangata likhopo li entsoe ka FR-4, e leng lelakabe la fiberglass epoxy material. Li sebelisetsoa ho matlafatsa libaka tse itseng tsa potoloho ea flex e hlokang tšehetso e eketsehileng kapa ho satalla. Likhopo li ka eketsoa libakeng tseo ho tsona lihokelo kapa likarolo li kenngoa ho fana ka matla a eketsehileng le botsitso ho potoloho.
Ntle le lisebelisoa tsena tse ka sehloohong, likarolo tse ling tse kang li-solders, liaparo tse sireletsang le lisebelisoa tsa ho sireletsa li ka sebelisoa nakong ea tlhahiso ea potoloho ea flex.E 'ngoe le e' ngoe ea lisebelisoa tsena e phetha karolo ea bohlokoa ho netefatsa ts'ebetso, ho tšoarella le ho ts'epahala ha lipotoloho tse tenyetsehang lits'ebetsong tse fapaneng.
Ka kakaretso, lisebelisoa tse atisang ho sebelisoa ha ho etsoa flex circuit fabric li kenyelletsa polyimide e le substrate, koporo e le mekhoa e tsamaisang, thepa e khomarelang bakeng sa ho kopanya, ho koahela likarolo tsa ho pata le ho sireletsa, le likhopo bakeng sa ho matlafatsa.E 'ngoe le e' ngoe ea lisebelisoa tsena e sebeletsa morero o itseng 'me hammoho e ntlafatsa ts'ebetso le ts'epahalo ea li-circuits tsa flex. Ho utloisisa le ho khetha thepa e nepahetseng ho bohlokoa bakeng sa ho hlahisa lipotoloho tse feto-fetohang tsa boleng bo holimo tse fihlelang litlhoko tse thata tsa lisebelisoa tsa sejoale-joale tsa elektroniki.
