Mumakore achangopfuura, kuitira kuzadzikisa zvido zve miniaturization yeimwe yepamusoro-yekupedzisira vatengi zvigadzirwa zvemagetsi, iyo chip kusangana iri kuwedzera kukwira uye kukwirira, iyo BGA pini nzvimbo iri kuswedera padyo nepedyo (isingasviki kana yakaenzana ne 0.4pitch), iyo Pcb dhizaini iri kuramba ichiwedzera kuumbana, uye iyo routing density iri kuve yakakura uye yakakura. Chero chero mutambi (odha zvisina tsarukano) tekinoroji inoshandiswa kuitira kugadzirisa dhizaini pasina kukanganisa mashandiro akaita sekuvimbika kwechiratidzo, Iyi ndiyo ALIVH chero dura IVH chimiro multilayer yakadhindwa wiring board.
Unyanzvi hunhu hwemhando ipi neipi kuburikidza negomba
Zvichienzaniswa nehunhu hwetekinoroji yeHDI, mukana weALIVH ndewekuti rusununguko rwekugadzira rwakawedzerwa zvakanyanya uye maburi anogona kurohwa akasununguka pakati pezvikamu, izvo zvisingakwanisike nehunyanzvi hweHDI. Kazhinji, vagadziri vekumba vanowana akaomeswa mamiriro, ndiko kuti, dhizaini yekugadzira yeHDI ndiyo yechitatu-odhiyo HDI bhodhi. Nekuti HDI haigamuchire zvizere laser yekuchera, uye gomba rakavigwa mukatikati remukati rinotora maburi emuchina, izvo zvinodiwa mugomba disc zvakakura kwazvo kupfuura maburi eraser, uye maburi emakanika anotora nzvimbo pane inopfuura dura. Naizvozvo, kazhinji kutaura, tichienzanisa nekuchera zvisina tsarukano kweALIVH tekinoroji, iyo pore dhayamita yemukati weplate ndiro inogona zvakare kushandisa 0.2mm micropores, iro richiri rakakura mukaha. Naizvozvo, iyo wiring nzvimbo yeALIVH bhodhi ingangodaro iri yepamusoro zvakanyanya kupfuura iyo yeHDI. Panguva imwecheteyo, kudhura uye kugadzirisa kunetsekana kweALIVH kwakakwirirawo kupfuura kweiyo HDI maitiro. Sezvinoratidzwa muMufananidzo 3, iwo mufananidzo wechirongwa weALIVH.
Dhizaini matambudziko ezvias mune chero dura
Yekupokana nhete kuburikidza netekinoroji inokanganisa zvachose iyo yechinyakare nenzira yekugadzira nzira. Kana iwe uchiri kuda kuseta vias mumatanho akasiyana, zvinowedzera kuoma kwemanejimendi. Dhizaini yekugadzira inoda kuve nekwanisi yekuchera zvine hungwaru, uye inogona kusanganiswa uye kupatsanurwa pakuda.
Cadence inowedzera iyo wiring yekutsiva nzira inoenderana nekushanda rukoko kune yechinyakare wiring nzira inoenderana netambo yekutsiva nhete, sekuratidzwa mumufananidzo 4: unogona kutarisa iyo dura iyo inogona kuita chiuno tambo mune rinoshanda dura pani, wobva wadzvanya kaviri gomba kusarudza chero dura rekutsiva newaya.
Muenzaniso we ALIVH dhizaini uye kugadzira ndiro:

Kuvigwa kuramba, kuvigwa kugona uye midzi midzi
Kubatanidzwa kwepamusoro uye miniaturization yemidziyo inochengetwa nemaoko inodiwa kuti kumhanyisa-kumhanyisa mukana weInternet nemasocial network. Parizvino vimba ne4-n-4 HDI tekinoroji. Nekudaro, kuti uwane kuzadzikiswa kwepamusoro kwekubatana kwechizvarwa chinotevera chetekinoroji nyowani, mune ino ndima, kupinza zvisina basa kana zvikamu zvinoshanda muPCB uye substrate zvinogona kusangana nezvinodiwa pamusoro. Paunogadzira nharembozha, kamera dzemadhijitari uye zvimwe zvigadzirwa zvemagetsi zvevatengi, ndiyo sarudzo yemazuva ano yekufunga maitiro ekupinza mativi anoshanda uye anoshanda muPCB uye substrate. Iyi nzira inogona kuve yakati siyanei nekuti iwe unoshandisa akasiyana vatengesi. Imwe mukana wezvikamu zvakadzamidzirwa ndezvekuti tekinoroji inopa yekuchengetedza midziyo yehungwaru kubva pane zvinonzi reverse design. Allegro PCB mupepeti anogona kupa mhinduro dzemabhizimusi. Allegro pcb mupepeti inogona zvakare kushanda zvakanyanya neHDI bhodhi, inoshanduka bhodhi uye yakadzamidzirwa zvikamu. Iwe unogona kuwana iyo chaiyo parameter uye zvipingamupinyi kupedzisa dhizaini yezvikamu zvakadzamidzirwa. Dhizaini yemidziyo yakadzamidzirwa haigone chete kurerutsa maitiro eSMT, asi zvakare inovandudza zvakanyanya kuchena kwezvigadzirwa.
Kuvigwa kuramba uye kugona dhizaini
Kuvigwa nemishonga, aizivikanwawo akavigwa nemishonga kana firimu nemishonga, ndiko kumanikidza chaiyo nemishonga zvinhu pamusoro insulating substrate, ipapo kuwana zvaida nemishonga ukoshi kuburikidza kudhinda, etching uye nezvimwewo, uye ipapo achizviendesa pamwe nevamwe pcb akaturikidzana kuumba munhu ndege yekudzivirira rukoko. Iyo yakajairika yekugadzira tekinoroji yePTFE yakavigwa kuramba multilayer yakadhindwa bhodhi inogona kuwana inodikanwa kuramba.
Iyo yakavigwa capacitance inoshandisa izvo zvinhu zvine yakakwira capacitance density uye inoderedza chinhambwe pakati pezvikamu kuita yakakura yakakura inter ndiro ndiro capacitance yekutamba chinzvimbo chekudzvanya uye kusefa kweiyo magetsi magetsi system, kuitira kuti ideredze iyo discrete capacitance inodiwa pabhodhi uye kuwana zvirinani kwepamusoro-frequency kusefa hunhu. Nekuti iyo infasitic inductance yekuvigwa capacitance idiki kwazvo, yayo resonant frequency poindi ichave iri nani pane yakajairwa capacitance kana yakaderera ESL capacitance.
Nekuda kwekukura kwemaitiro uye tekinoroji uye kudiwa kweiyo-yekumhanyisa dhizaini yemagetsi magetsi system, yakavigwa kugona tekinoroji kunoiswa zvakanyanya uye nekuwedzera. Tichishandisa yakavigwa kugona tekinoroji, isu chekutanga tinofanirwa kuverenga saizi yefurateti yeplate capacitance Mufananidzo 6 flat flat capacitance calculation fomula
Izvo izvo:
C ndiyo capacitance yeakavigwa capacitance (ndiro capacitance)
A inzvimbo yemahwendefa akapfava. Mune akawanda magadzirirwo, zvinonetsa kuwedzera nzvimbo iri pakati pemaplate akapetwa kana chimiro chakatemwa
D_ K ndiyo dielectric inogara iri pakati nepakati pamahwendefa, uye iyo capacitance pakati pemahwendefa yakanangana zvakananga neiyo dielectric nguva dzose.
K inobvumidza kubvumidza, inozivikanwawo sevhisi yekubvumidza. Icho chinogara chiri chemuviri chine kukosha kwe8.854 187 818 × 10-12 farad / M (F / M);
H ndiko hukobvu pakati pendege, uye iyo capacitance pakati pemahwendefa inopindirana zvakaenzana neukobvu. Naizvozvo, kana isu tichida kuwana yakakura capacitance, isu tinofanirwa kudzikisa iyo interlayer ukobvu. 3M c-ply yakavigwa capacitance zvinhu inogona kuwana interlayer dielectric ukobvu hwe0.56mil, uye dielectric kugara kwe16 kunowedzera zvakanyanya capacitance pakati pamahwendefa.
Mushure mekuverenga, 3M c-ply yakavigwa capacitance zvinhu inogona kuwana inter plate ndiro capacitance ye 6.42nf pa square square.
Panguva imwecheteyo, zvinodawo kuti ushandise PI simulation chishandiso kutevedzera iyo impedance yeiyo PDN, kuitira kuona capacitance dhizaini yebhodhi rimwe chete uye kudzivirira iyo yakasarudzika dhizaini yekuviga capacitance uye discrete capacitance. Mufananidzo 7 inoratidza iyo PI simulation mhedzisiro yeakavigwa kugona dhizaini, ichingotarisa mhedzisiro yepakati bhodhi capacitance isina kuwedzera mhedzisiro ye discrete capacitance. Izvo zvinogona kuonekwa kuti chete nekuwedzera huwandu hwakavigwa, iko kushanda kwesimba rese impedance curve kwakagadziridzwa zvakanyanya, kunyanya pamusoro pe500MHz, inova frequency bhendi umo iro bhodhi renzvimbo discrete firita capacitor yakaoma kushanda. Iyo bhodhi capacitor inogona kunyatso kuderedza simba impedance.
