12-Layer PCB: Ho Lekola Moralo oa Boto ea Potoloho, Boqapi, Boiketlo, le Likopo

Lefapheng la lisebelisoa tsa elektronike tsa morao-rao, lipotoloho tse rarahaneng li tloaelehile, 'me ho amohela meralo ena e rarahaneng ho hloka hore ho sebelisoe li-PCB tse ngata. Tharollo e 'ngoe e joalo e feto-fetohang ke PCB ea mekato e 12. Patlisisong ena e felletseng, re tla batlisisa lefats'eng la li-PCB tse mekato e 12, tse akaretsang moralo oa tsona, maqheka, pokello le lits'ebetso tse fapaneng.

Ho utloisisa 12-Layer PCB

PCB ea mekato e 12 ke karolo ea mantlha tikolohong ea lipotoloho tsa elektroniki tse tsoetseng pele, haholo indastering ea likoloi. E bapala karolo ea bohlokoa ho theheng likhokahano tse tšepahalang, 'me e etsa hore e be ea bohlokoa haholo lits'ebetsong tse kang tsamaiso ea ho tsamaea, likarolo tsa taolo ea phetisetso, likopano tsa elektronike le likarolo tse ling tse fapaneng tsa koloi.

E 'ngoe ea litšobotsi tse hlalosang PCB ea 12-layer ke bokhoni ba eona ba ho mamella maemo a thata a tikoloho le mocheso o phahameng. Li-PCB tsena hangata li hahiloe ho sebelisoa polyimide, e leng ntho ea tlhaho e tsebahalang ka ho hanyetsa mocheso o ikhethang. Ho feta moo, bahlahisi ba bang ba sebelisa khauta bakeng sa ho qeta bokaholimo, ho matlafatsa botsitso ba PCB libakeng tse thata. Licheso tsa mocheso ka linako tse ling li kenyellelitsoe ho thusa ho qhala mocheso hantle, ho matlafatsa ts'ebetso ea nako e telele ea PCB.

Ha ho tluoa tabeng ea khatello ea mocheso, PCB ea mekhahlelo e 12 e ka mamella mocheso o fihlang ho likhato tse 288 tsa Celsius ho fihlela metsotsoana e 20, ka taolo ea impedance hangata e ka har'a +/-10%. Ho feta moo, ha e bapisoa le li-PCB tse ling tse nang le mekhahlelo e mengata joalo ka mefuta ea mekhahlelo e 8 le mekhahlelo e 10, li-PCB tsa mekhahlelo e 12 li theko e tlase, e leng se etsang hore e be khetho e khahlang bakeng sa lits'ebetso tse fapaneng.

Bohlokoa ba 12-Layer PCB Stackup

12-layer PCB stackup ke karolo ea bohlokoa ea moralo oa boto ea potoloho e hatisitsoeng ka mekhahlelo e mengata. E kenyelletsa litlhoko tse khethehileng bakeng sa botenya ba thepa le ho latela bophahamo ho thusa ho hlophisa lihlopha tse fapaneng holim'a boto e le 'ngoe. Sebopeho sa stackup se bohlokoa bakeng sa ho fihlela ts'ebetso le ts'ebetso e lakatsehang ea motlakase.

Lisebelisoa tse peli tsa mantlha li bohlokoa ho aheng PCB ea mekato e 12: botenya ba mantlha le prepreg. Lisebelisoa tsa mantlha li sebetsa e le lera le bohareng ka har'a stackup ea PCB, e fana ka thepa e thata le ea motlakase e hlokahalang. Lisebelisoa tsa Prepreg, ka lehlakoreng le leng, li entsoe ka likhalase tse entsoeng ka resin 'me li sebelisoa ho tlatsa likheo pakeng tsa lifolakha tsa koporo, haholo-holo likarolong tse kopanyang le li-cores tsa ka ntle.

Ha ho ralwa mealo e ka ntle ya PCB, ho sebediswa difoile tsa koporo tse nang le boima bo fapaneng, hangata bonyane di-ounces tse 0.5, ho sebediswa. Maemong a mangata, di-PCB tse nang le mealo e 12 di hlahiswa ka katleho hodima diboto tse nang le botenya bo tloaelehileng ba 1.6mm. Bakeng sa meralo e rarahaneng haholoanyane, mealo e eketsehileng (mealo e 14 ho isa ho e 16) e ka kenngwa ka hara diboto tsena tse teteaneng. Palo e nepahetseng ya mealo e itshetlehile ka bokgoni ba moetsi ba ho hlahisa diboto tsa kgokelo ya maqhubu a phahameng (HDI).

12-Layer PCB Fabrication Process

Ho etsoa ha 12-layer PCB ho kenyelletsa letoto la lits'ebetso tse rarahaneng tse qetellang ka tlhahiso ea boto ea potoloho ea multilayer e sebetsang ka botlalo. Ts'ebetso ena e akaretsa mekhahlelo e fapaneng, e 'ngoe le e' ngoe e sebeletsa morero o itseng oa ho etsa hore PCB e phele.

1. Ho etsa litšoantšo: Moralo oa dijithale oa PCB oa phethahala ebe o fetisetsoa botong ho sebelisoa mekhoa e tsamaisoang ke software.
2. Etching: Tšepe e feteletseng e tlosoa boto ea potoloho e hatisitsoeng ho sebelisoa li-solvents tsa indasteri, ho hloekisa mekhoa ea potoloho.
3. Lamination: Likarolo tse 12 tsa PCB li kopantsoe hammoho ho sebelisoa mochini o hatisang, e leng se hlahisang boto e kopaneng.
4. Ho cheka: Ho cheka ka lesoba le ka lesoba ho etsoa ho theha likhokahano lipakeng tsa likarolo tse 12 tsa PCB.
5. Plating: Qetello ea tšepe e sebelisoa ho li-vias le likoti, ho netefatsa khokahano e nepahetseng ea motlakase.
6. Kopo ea Mask ea Solder: Lera le sireletsang la polymer, le tsejoang ka hore ke solder mask, le sebelisoa holim'a PCB ho thibela oxidation le marokho a solder lipakeng tsa lipampiri tse arohaneng haufi.
7. Khatiso ea Silkscreen: Lintlha le matšoao li hatisoa holim'a PCB, li thusa ho kopanya le ho tsebahatsa.
8. Tiisetso ea Boleng: PCB e felileng e etsa liteko tse matla ho netefatsa hore na e sebetsa joang le ho latela melao ea moralo.

Karolo ea Boto ea Potoloho ea PCB ea Melato e 12

Boto ea potoloho ea 12-layer PCB e ikhetholla ka boholo ba eona bo kopaneng ha bo bapisoa le balekane ba eona ba le bang kapa ba habeli. compactness ena e finyelloa ka stacking 12 magato a holim'a e mong le e hokela bona ka vias. Sephetho ke boto ea potoloho e hatisitsoeng ka bongata, e hatisitsoeng, e loketseng lits'ebetso tse kang lilaptop, mehala ea cellular le tse ling.

Ho sa tsotellehe boholo ba eona bo fokotsehileng, boto ea potoloho ea 12-layer PCB e matla ebile e tšoarella ka nako e telele, ka lebaka la mohaho oa eona oa 12 le mocheso o phahameng oo o o mamellang nakong ea tlhahiso. Li-laminate tse sebelisetsoang ho kopanya lihlopha li phetha karolo ea bohlokoa ho matlafatsa nako ea tsona.

Ho feta moo, boto ea potoloho ea 12-layer PCB e ithorisa ka sekhahla se phahameng sa potoloho ha se bapisoa le mapolanka a le mong kapa a mabeli. Sena se lumella ho soasoa ha likarolo tse ling ka har'a sebaka se lekanyelitsoeng, ho ntlafatsa haholo ts'ebetso ea PCB. Boemo bo bonyenyane, boima bo phahameng ba potoloho, le ho tšoarella li etsa hore li-PCB tse 12 li loketse lits'ebetso tse boima joalo ka li-supercomputers, likarete tsa litšoantšo, lisebelisoa tsa merafo tsa cryptocurrency, lisebelisoa tsa komporo ea quantum, le lisebelisoa tsa mahlale a maiketsetso.

Lisebelisoa tsa 12-Layer PCBs

Liboto tsa potoloho tse hatisitsoeng tse 12 li fumana lits'ebetso liindastering le lihlahisoa tse fapaneng, ho kenyelletsa:

1. Consumer Electronics

fihlela qeto e

Ka kakaretso, li-PCB tse nang le mekhahlelo e 12 li emela tharollo e feto-fetohang bakeng sa ho amohela meralo e rarahaneng ea potoloho ka mokhoa o kopaneng le o tšoarellang. Ho utloisisa mathata a li-PCB tse nang le mekhahlelo e 12, ho kenyeletsoa le moralo oa tsona, ho bokellana le lits'ebetso tsa tlhahiso, ho bohlokoa bakeng sa ho sebelisa bokhoni ba tsona bo felletseng lits'ebetsong tse fapaneng.

Ha o sebetsa le li-PCB tse 12-layer, ho bohlokoa ho sebelisana 'moho le bahlahisi ba tsebahalang ho netefatsa hore ho sebelisoa mekhoa e nepahetseng ea ts'ebetso le moralo oa ho qetela o tsamaellana le litlhoko tsa hau tse ikhethileng. Ho khetha moetsi ea nepahetseng ho bohlokoa ho fihlela ts'ebetso e lakatsehang le ts'epahalo ea li-PCB tsa hau tse 12.

Bakeng sa li-PCB tsa boleng bo holimo tse 12 le lits'ebeletso tse tšepahalang tsa tlhahiso, ikopanye le rona kajeno ho buisana ka litlhoko tsa projeke ea hau.

Ha projeke e tloha ho dipatlisiso ho ya ho RFQ, hlahloba tlhahlobo ya rigid-flex stackup le PCB ya motheo wa tshepe e futhumetseng e le hore ditlhoko tsa thepa, tshebetso le tlhahlobo di dule di tsamaellana.
