Ho feto-fetoha ha Maboto a Rigid-Flex ho Amohelang Matšoao a Lebelo le Phahameng

Tsebisa:

Ka blog ena, re tla hlahloba ho feto-fetoha ha liboto tse thata-thata le bokhoni ba tsona ba ho sebetsana le matšoao a lebelo le phahameng.

Lefatšeng la kajeno la theknoloji e tsoetseng pele, moo lisebelisoa tsa elektroniki li ntseng li fetoha tse nyane, tse bobebe le tse rarahaneng, tlhoko ea liboto tsa potoloho tse hatisitsoeng ka lebelo le holimo (PCBs) e ntse e eketseha.Liboto tse thata-thata li hlahile e le tharollo e sebetsang e kopanyang melemo ea li-PCB tse thata le tse tenyetsehang, e leng se etsang hore e be tse loketseng bakeng sa ho amohela matšoao a lebelo le phahameng.

Karolo ea 1: Ho utloisisa Maboto a Rigid-Flex

Rigid-flex ke mofuta oa lebasetere oa PCB o kopanyang likarolo tsa lisebelisoa tse thata le tse tenyetsehang.Liboto tsena li na le lipotoloho tse tenyetsehang tse hokahaneng le likarolo tse thata, tse fanang ka botsitso ba mochini le ho fetoha habonolo.Motsoako oa likarolo tse thata le tse tenyetsehang li lumella boto hore e kobehe kapa e mene ha ho hlokahala ntle le ho ama ts'ebetso ea eona.

Karolo ea 2: Phetiso ea Letšoao le Lebelo le Phahameng

Matšoao a lebelo le phahameng a fetoha ka potlako matšoao a motlakase a fetang moeli o itseng oa maqhubu.Lipontšo tsena li hloka ho nahanoa ka mokhoa o khethehileng nakong ea moralo le sebopeho sa PCB ho qoba litaba tsa bots'epehi ba matšoao joalo ka crosstalk, impedance mismatch, le tšitiso ea matšoao.Li-Rigid-flex board li na le melemo e ikhethang ea ho sebetsana le matšoao a lebelo le phahameng ka lebaka la ho feto-fetoha ha tsona le sebaka se khuts'oane sa phetisetso ea matšoao.

Karolo ea 3: Lintlha tsa moralo o thata-tenyetsehang bakeng sa matshwao a lebelo le phahameng

3.1 Impedans e laoloang:
Ho boloka impedance e laoloang ke ea bohlokoa bakeng sa botšepehi ba pontšo ea lebelo le phahameng.Liboto tse thata-thata li lumella taolo e ntle ea impedance hobane likarolo tse feto-fetohang li ka etsoa ka li-geometri le bophara bo nepahetseng.Sena se lumella hore ho be le liphetoho tse fokolang tsa litsamaiso bakeng sa matšoao a matšoao, ho netefatsa hore ho na le tšitiso e tsitsitseng ho pholletsa le boto.

3.2 Ho tsamaisa mats'oao le ho phuthela ka mekhahlelo:
Mokhoa o nepahetseng oa ho tsamaisa mats'oao le ho bokellana ka sekhahla ho bohlokoa ho fokotsa phallo ea matšoao le ho fihlela ts'ebetso e nepahetseng.Mapolanka a rigid-flex a lumella ho behoa habonolo ha matšoao a lebelo le phahameng, kahoo a khutsufatsa sebaka sa phetisetso le ho fokotsa likamano tse sa batleheng tsa matšoao.Ho feta moo, bokhoni ba ho bokella mekhahlelo e mengata ka har'a compact form factor e nolofalletsa karohano e sebetsang ea matla le lifofane tsa fatše, e leng ho matlafatsang botšepehi ba matšoao.

3.3 EMI le phokotso ea crosstalk:
Ho kena-kenana le motlakase (EMI) le crosstalk ke liqholotso tse tloaelehileng ha u sebetsana le matšoao a lebelo le phahameng.Monyetla oa mapolanka a thata-thata ke motsoako oa tšireletso le tlhophiso e nepahetseng ea sefofane sa fatše, se fokotsang kotsi ea EMI le crosstalk.Sena se tiisa hore letšoao le lula le tsitsitse ebile le se na tšitiso, ho ntlafatsa tshebetso ea tsamaiso ka kakaretso.

Karolo ea 4: Melemo le ts'ebeliso ea liboto tsa lebelo le phahameng tsa rigid-flex

4.1 Moralo o bolokang sebaka:
Liphanele tsa rigid-flex li na le melemo e mengata lits'ebetsong moo sebaka se lekanyelitsoeng.Bokhoni ba bona ba ho kobeha le ho ikamahanya le sebaka se fumanehang bo lumella tšebeliso e nepahetseng ea sebaka, ho etsa hore e be tse loketseng lisebelisoa tsa elektroniki tse kopaneng.

4.2 Ho tšepahala le ho tšoarella:
Liboto tse thata-thata li fana ka ts'epo e kholo ho feta li-PCB tse thata tsa setso ka lebaka la palo e fokotsehileng ea khokahano le lintlha tse ka bang teng tsa ho hloleha.Ho feta moo, ho ba sieo ha likhokahano le likhoele tsa ribone ho fokotsa kotsi ea ho senyeha ha matšoao le ho netefatsa ho tšoarella ha nako e telele.

4.3 Tšebeliso:
Li-Rigid-flex board li sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa sefofane, lisebelisoa tsa bongaka, lisebelisoa tsa elektroniki tsa bareki le likoloi.Ke khetho ea pele bakeng sa lits'ebetso moo boholo, boima le ts'epahalo li leng bohlokoa le moo ho hlokahalang phetiso ea mats'oao a lebelo.

Ha re phethela:

Ha tlhoko ea phetisetso ea mats'oao a lebelo le holimo e ntse e hola, liboto tse thata tse feto-fetohang li fetohile tharollo e fapaneng.Motsoako oa bona o ikhethang oa ho feto-fetoha ha maemo, moralo o bolokang sebaka le likarolo tsa botšepehi ba matšoao li etsa hore e be tse loketseng bakeng sa ho amohela matšoao a lebelo le phahameng.Ka ho kopanya impedance e laoloang, mokhoa o nepahetseng oa ho tsamaisa lipontšo le mekhoa e nepahetseng ea ho fokotsa EMI/crosstalk, liboto tse thata-thata li netefatsa ts'ebetso e tšepahalang le e nepahetseng lits'ebetsong tse fapaneng.
