Ntlafatsa sebopeho sa HDI Flex PCB le likhokahano ho ntlafatsa boleng ba matšoao le ho fokotsa bolelele ba ho latella

Tsebisa:

Ka poso ena ea blog, re tla hlahloba lintlha tsa bohlokoa le mekhoa eo re lokelang ho e latela ho fokotsa bolelele ba ho latela 'me qetellong re ntlafatse boleng ba pontšo ea HDI flex PCB.

High-density interconnect (HDI) flexible printed circuit boards (PCBs) ke khetho e ntseng e tuma haholo ho lisebelisoa tsa elektronike tsa sejoale-joale ka lebaka la ho momahana le ho feto-fetoha ha tsona.Leha ho le joalo, ho rala le ho kenya tšebetsong mokhoa o nepahetseng oa ho beha likarolo le mekhoa ea khokahano bakeng sa li-PCB tse tenyetsehang tsa HDI e ka ba mosebetsi o boima.

Bohlokoa ba ho beha likarolo le mekhoa ea ho hokahanya:

Moralo oa likarolo le mekhoa ea khokahano e na le tšusumetso e kholo ts'ebetsong e akaretsang ea li-PCB tse feto-fetohang tsa HDI.Ho beha likarolo ka nepo le mekhoa ea ho tsamaisa melaetsa e ka ntlafatsa boleng ba matšoao le ho fokotsa ho khopama ha mats'oao.Ka ho fokotsa bolelele ba mohala, re ka fokotsa tieho ea phetisetso le tahlehelo ea matšoao, kahoo ra ntlafatsa ts'epahalo le ts'ebetso ea sistimi.

Lintho tse lokelang ho nahanoa ha u khetha moralo oa likarolo:

1. Tlhahlobo ea phallo ea lets'oao:

Pele o qala ho beha likarolo, ho bohlokoa ho utloisisa phallo ea matšoao le ho tseba tsela ea bohlokoa.Ho sekaseka litsela tsa mats'oao ho re fa monyetla oa ho ntlafatsa ho beoa ha likarolo tse amang haholo botšepehi ba mats'oao.

2. Ho beoa ha likarolo tsa lebelo le phahameng:

Likarolo tsa lebelo le phahameng, joalo ka li-microprocessors le li-memory chips, li hloka tlhokomelo e khethehileng.Ho beha likarolo tsena haufi le tse ling ho fokotsa tieho ea phatlalatso ea matšoao 'me ho fokotsa tlhoko ea mesaletsa e telele.Ho feta moo, ho beha likarolo tse lebelo le phahameng haufi le phepelo ea motlakase ho thusa ho fokotsa impedance ea marang-rang ea phepelo ea matla (PDN), ho thusa ho tšepahala ha matšoao.

3. Ho arola likarolo tse amanang:

Ho arola likarolo tse amanang le tsona (joalo ka likaroloana tsa digital le analog) ka sebopeho ho thibela tšitiso le ho buisana.Ho boetse ho kgothaletswa ho arola matshwao a dijithale le analoge ka lebelo le phahameng ho qoba ho kopanya le ho kena-kenana.

4. Decoupling capacitor:

Li-decoupling capacitor li bohlokoa ho boloka matla a tsitsitseng ho li-circuits tse kopaneng (ICs).Ho li beha haufi le likhoele tsa motlakase tsa IC ho fokotsa inductance le ho eketsa katleho ea phepelo ea motlakase.

Lintho tseo u lokelang ho li ela hloko ha u khetha mokhoa oa ho hokahanya:

1. Litsela tse peli tse fapaneng:

Lipara tse fapaneng li sebelisoa hangata bakeng sa phetiso ea data e potlakileng.Tsela e nepahetseng ea lipara tse fapaneng ke ea bohlokoa ho boloka botšepehi ba matšoao.Ho boloka mesaletsa e bapile le ho boloka sebaka se sa feleng lipakeng tsa mesaletsa ho thibela lets'oao le ho fokotsa tšitiso ea motlakase (EMI).

2. Taolo ea tšitiso:

Ho boloka impedance e laoloang ke ea bohlokoa bakeng sa phetisetso ea matšoao a lebelo le phahameng.Ho sebelisa mekhoa e laoloang ea impedance bakeng sa matshwao a lebelo le phahameng ho ka fokotsa ho bonahatsa le ho sotha ha matshwao.Ho kenyelletsa li-calculator tsa impedance le lisebelisoa tsa ketsiso ts'ebetsong ea moralo ho ka thusa haholo ho fihlela taolo e nepahetseng ea impedance.

3. Tsela e tobileng:

Ho fokotsa bolelele ba tsela, ho kgothaletswa ho khetha litsela tse otlolohileng neng kapa neng ha ho khoneha.Ho fokotsa palo ea vias le ho sebelisa bolelele bo khuts'oane ba ho latela mohlala ho ka ntlafatsa haholo boleng ba matšoao ka ho fokotsa tahlehelo ea matšoao.

4. Qoba ho kobeha le likhutlong:

Ho kobeha le likhutlo tse latelang ho hlahisa ho se sebetse ho eketsehileng le ho khaotsa ho etsa lipontšo, ho bakang ho fokotseha ha lets'oao.Ho tsamaisa litseleng tse otlolohileng kapa li-curve tsa radius tse kholo ho thusa ho fokotsa ponahalo ea matšoao le ho boloka botšepehi ba matšoao.

Liphetho le melemo:

Ka ho latela menahano le mekhoa e boletsoeng ka holimo, baqapi ba ka fihlella ho beoa ha likarolo ka botlalo le mekhoa ea khokahano bakeng sa li-PCB tse feto-fetohang tsa HDI.U ka fumana melemo e latelang:

1. Ntlafatsa boleng ba lets'oao:

Ho fokotsa bolelele ba mohala ho fokotsa tieho ea phetisetso, tahlehelo ea mats'oao, le ho sotha mats'oao.Sena se ntlafatsa boleng ba matšoao le ho ntlafatsa ts'ebetso ea sistimi.

2. Fokotsa lipuisano le tšitiso:

Karohano e nepahetseng ea likarolo le karohano e ka fokotsa puisano le tšitiso, ka ho etsa joalo ea ntlafatsa botsitso ba matšoao le ho fokotsa lerata la sistimi.

3. Ts'ebetso e ntlafalitsoeng ea EMI/EMC:

Mekhoa e nepahetseng ea cabling le taolo ea impedance e fokotsa tšitiso ea motlakase le ho ntlafatsa tšebelisano ea motlakase ea sistimi.

4. Kabo ea matla e sebetsang hantle:

Ho beoa ka leano la likarolo tsa lebelo le phahameng le li-capacitor tse kopanyang ho ntlafatsa katleho ea kabo ea matla, ho matlafatsa ts'epo ea matšoao.

Ha re phethela:

Ho ntlafatsa boleng ba lets'oao le ho fokotsa bolelele ba trace ho HDI flex PCBs, baqapi ba tlameha ho nahana ka hloko ka sebopeho sa likarolo le mekhoa ea khokahano.Ho sekaseka phallo ea mats'oao, ho beha likarolo tsa lebelo le holimo hantle, ho sebelisa li-capacitor tsa decoupling, le ho kenya ts'ebetsong mekhoa e ntlafalitsoeng ea ho tsamaisa li bapala karolo ea bohlokoa ho fihlelleng botšepehi bo nepahetseng ba matšoao.Ka ho latela litataiso tsena, baetsi ba lisebelisoa tsa elektronike ba ka etsa bonnete ba nts'etsopele ea li-PCB tse sebetsang hantle le tse tšepahalang tsa HDI.
