Theknoloji ea tlhahiso ea liboto tsa potoloho tse hatisitsoeng tse thata-flex

Ka poso ena ea blog, re tla hlahloba mahlale a fapaneng a tlhahiso a sebelisoang ho hlahisa li-PCB tse sa fetoheng le ho hlahloba bohlokoa ba tsona ts'ebetsong ea tlhahiso.

Liboto tse hatisitsoeng tse thata tse hatisitsoeng (PCBs) li ntse li ata haholo indastering ea lisebelisoa tsa elektroniki ka lebaka la melemo ea tsona e mengata ho feta li-PCB tsa setso tse thata kapa tse tenyetsehang. Liboto tsena tse ncha li kopanya ho tenyetseha le ho tšoarella, ho li etsa tse loketseng lits'ebetso moo sebaka se lekanyelitsoeng le ho tiea ho leng bohlokoa. Ho etsa mapolanka a rigid-flex ho kenyelletsa mekhoa e fapaneng ea theknoloji ho etsa bonnete ba hore ho etsoa ka mokhoa o nepahetseng le ho kopanya liboto tsa potoloho.

1. Lintlha tsa moralo le khetho ea thepa:

Pele o qala ho sheba theknoloji ea tlhahiso, moralo le likarolo tsa thepa ea li-PCB tse sa fetoheng li tlameha ho nahanoa. Moralo o tlameha ho hlophisoa ka hloko, ho nahanoa ka ts'ebeliso e reriloeng ea boto, litlhoko tsa ho feto-fetoha le maemo a mangata a hlokahalang. Khetho ea thepa e bohlokoa ka ho lekana kaha e ama ts'ebetso ka kakaretso le ho ts'epahala ha boto. Ho khetha motsoako o nepahetseng oa li-substrates tse tenyetsehang le tse thata, likhomaretsi le lisebelisoa tse tsamaisang ho bohlokoa ho netefatsa liphetho tse lakatsehang.

2. Ho etsoa ha potoloho e bonolo:

Ts'ebetso ea tlhahiso ea potoloho ea flex e kenyelletsa ho theha likarolo tse feto-fetohang ho sebelisa polyimide kapa filimi ea polyester joalo ka substrate. Filimi e sebetsana le letoto la lits'ebetso tse kang ho hloekisa, ho roala, ho nka litšoantšo, etching le electroplating ho etsa mokhoa o lakatsehang oa potoloho. Joale lera le tenyetsehang le kopanngoa le lera le thata ho etsa PCB e tsitsitseng e tsitsitseng.

3. Ho etsa potoloho e thata:

Karolo e thata ea PCB e sa fetoheng e etsoa ho sebelisoa mekhoa ea setso ea ho etsa PCB. Sena se kenyelletsa lits'ebetso tse kang ho hloekisa, ho nka litšoantšo, ho khabisa le ho roala li-laminate tse thata. Ka mor'a moo, lera le thata lea lumellana 'me le tlamahanngoa le lera le tenyetsehang ka ho sebelisa sekhomaretsi se khethehileng.

4. Ho cheka le ho rala:

Ka mor'a hore li-circuits tse feto-fetohang le tse thata li entsoe, mohato o latelang ke ho phunya masoba ho lumella ho beoa ha likarolo le likhokahano tsa motlakase. Ho phunya masoba ka har'a PCB e thata-fetohang ho hloka hore ho behoe ka nepo ho etsa bonnete ba hore masoba a likarolo tse flex le tse thata a hokahantsoe. Ka mor'a hore ts'ebetso ea ho cheka e phethoe, likoti li kenngoa ka thepa ea conductive ho theha likhokahano tsa motlakase pakeng tsa lihlopha tse fapaneng.

5. Kopano ea likarolo:

Kopano ea likarolo ho li-PCB tse thata-flex e ka ba phephetso ka lebaka la motsoako oa lisebelisoa tse tenyetsehang le tse thata. Theknoloji ea Traditional surface Mount (SMT) e sebelisoa bakeng sa likarolo tse thata, athe theknoloji e khethehileng e kang flex bonding le flip-chip bonding e sebelisetsoa libaka tse feto-fetohang. Mekhoa ena e hloka basebetsi ba nang le litsebo le lisebelisoa tse khethehileng ho etsa bonnete ba hore likarolo li kenngoa ka nepo ntle le ho baka khatello ea kelello likarolong tse tenyetsehang.

6. Teko le tlhahlobo:

Ho netefatsa boleng le ts'epahalo ea mapolanka a thata-thata, ho hlokahala mekhoa e matla ea ho hlahloba le ho hlahloba. Etsa liteko tse fapaneng tse kang tlhahlobo ea tsoelo-pele ea motlakase, tlhahlobo ea botšepehi ba matšoao, ho palama baesekele e futhumetseng le tlhahlobo ea vibrate ho lekola bokhoni ba tšebetso ba boto ea potoloho. Ho feta moo, etsa tlhahlobo e phethahetseng ea pono ho bona hore na ha ho na liphoso kapa liphoso tse ka amang tšebetso ea boto.

7. Qetello ea ho qetela:

Mohato oa ho qetela oa ho etsa PCB e thata-flexible ke ho sebelisa lesela le sireletsang ho sireletsa potoloho ho tloha linthong tsa tikoloho tse kang mongobo, lerōle le ho fetoha ha mocheso. Li-coatings li boetse li phetha karolo ea bohlokoa ho ntlafatsa ho tšoarella ka kakaretso le ho hanyetsa ha boto.

Ka kakaretso

Ho hlahisa mapolanka a rigid-flex ho hloka motsoako oa mekhoa e khethehileng ea tlhahiso le ho nahanela ka hloko. Ho tloha ho moralo le khetho ea thepa ho ea ho tlhahiso, kopano ea likarolo, tlhahlobo le ho qeta, mohato o mong le o mong ke oa bohlokoa ho netefatsa ts'ebetso le nako e telele ea boto ea potoloho ea hau. Ha indasteri ea lisebelisoa tsa elektroniki e ntse e tsoela pele, ho lebelletsoe hore theknoloji ea tlhahiso e tsoetseng pele le e sebetsang e tla tsoela pele ho nts'etsapele nts'etsopele ea liboto tse thata, ho bula menyetla e mecha ea ts'ebeliso ea tsona lits'ebetsong tse fapaneng tsa maemo a holimo.
