Kunakisa HDI pcb

Ngatinyatso tarisei kukanganisa. Kuwedzera kwepacity density kunotibvumira kupfupisa nzira dzemagetsi pakati pezvinhu. NeHDI, isu takawedzera huwandu hwenzvimbo dzewiring pamatanho emukati ePBB, nekudaro tichideredza huwandu hwese hwedenga hunodiwa mukugadzirwa. Kuderedza huwandu hwematanho kunogona kuisa kwakawanda kubatana pane imwechete bhodhi uye kugadzirisa chinzvimbo kuiswa, wiring uye kubatana. From there, we can focus on a technique called interconnect per Layer (ELIC), which helps design teams move from thicker boards to thinner flexible ones to maintain strength while allowing the HDI to see functional density.

HDI PCB rely on lasers rather than mechanical drilling. In turn, the HDI PCB design results in a smaller aperture and smaller pad size. Kuderedza kuzarura kwakabvumira timu yekugadzira kuti iwedzere marongerwo enzvimbo yebhodhi. Kupfupisa nzira dzemagetsi uye kugonesa kuwedzeredza wiring kunovandudza chiratidzo chekuvimbika kweiyo dhizaini uye inomhanyisa kugadzirisa chiratidzo. Isu tinowana yakawedzera bhenefiti muhuwandu nekuti isu tinodzora mukana we inductance uye capacitance matambudziko.

HDI PCB dhizaini haishandisi kuburikidza nemakomba, asi mapofu uye akaviga maburi. Kudzadzarika uye kuiswa kwakaringana kwekuvigwa uye maburi mapofu kunoderedza kumanikidza kumanikidza pahwendefa uye kunodzivirira chero mukana wekupokana. Uye zvakare, iwe unogona kushandisa yakaturikidzana kuburikidza-maburi kusimudzira ekubatanidza mapoinzi uye nekuvandudza kuvimbika. Kushandisa kwako pamapadhi kunogona zvakare kudzikisa kurasikirwa kwemasaini nekuderedza kunonoka kwemuchinjikwa uye kudzikisira hutachiona.

Kugadzirwa kweHDI kunoda kubatana

Kugadzira dhizaini (DFM) inoda inofungidzirwa, chaiyo pcb dhizaini nzira uye inowirirana kutaurirana nevagadziri uye vagadziri. Sezvo isu patakawedzera HDI kune iyo DFM portfolio, kutarisa kune zvakadzama pane dhizaini, kugadzira, uye kugadzira masitepisi kwakatonyanya kukosha uye kusangana uye kuyedza nyaya dzaifanira kugadziriswa. Muchidimbu, dhizaini, prototyping uye yekugadzira yeHDI PCBS inoda kubatana kwekubatana uye kutarisisa kune yakatarwa DFM mitemo inoshanda kune chirongwa.

Chimwe chezvinhu zvakakosha zveiyo HDI dhizaini (kushandisa laser kuchera) inogona kuve inopfuura kugona kwemugadziri, muunganidzi, kana mugadziri, uye inoda kutaurirana kunongedzera maererano nekururamisa uye mhando yemhando yekuchera inodiwa. Nekuda kweiyo yepazasi yekuvhura chiyero uye yepamusoro dhizaini yeiyo HDI PCBS, dhizaini dhizaini yaifanira kuona kuti vagadziri nevagadziri vanogona kusangana neungano, rework uye kuwelda zvinodiwa zveHDI dhizaini. Naizvozvo, magadzirirwo zvikwata anoshanda paHDI pcb magadzirirwo anofanirwa kuve nehunyanzvi mumatekiniki akaomarara anoshandiswa kugadzira mapuranga.

Ziva rako redunhu bhodhi zvinhu uye maratidziro

Nekuti kugadzirwa kweHDI kunoshandisa akasiyana maseru ekuchera laser, hurukuro pakati peboka rekugadzira, mugadziri uye mugadziri anofanirwa kutarisa pamhando yemabhodhi pavanenge vachikurukura nezvekuchera kwacho. Icho chigadzirwa chishandiso chinokurudzira dhizaini dhizaini inogona kuva nehukuru uye huremu zvinodiwa izvo zvinofambisa hurukuro mune imwe nzira kana imwe. Yakakwira frequency maficha ingangoda zvigadzirwa kunze kweyakajairwa FR4. Pamusoro pezvo, zvisarudzo nezverudzi rweFR4 zvinhu zvinokanganisa sarudzo nezve kusarudzwa kwenzira dzekuchera kana zvimwe zviwanikwa zvekugadzira. Nepo mamwe masisitimu achibaya nemhangura zviri nyore, mamwe haapindire mukati megirazi magirazi.

Pamusoro pekusarudza chaicho mhando yezvinhu, dhizaini dhizaini inofanirwa zvakare kuona kuti mugadziri nemugadziri vanogona kushandisa chaiyo ndiro ukobvu uye marata maitiro. Nekushandisa kwe laser kuchera, iyo aperture reshiyo inoderera uye kudzika reshiyo yemakomba anoshandiswa pakuzadza kuzadza anoderera. Kunyangwe mahwendefa mukobvu achibvumidza apasi madiki, izvo zvinoda kuitwa zveprojekti zvinogona kudoma mahwendefa matete ayo anogona kukundikana pasi pemamwe mamiriro ezvakatipoteredza. Dhizaini yekugadzira yaifanirwa kutarisa kuti mugadziri aive nekwanisi yekushandisa nzira ye “interconnect layer” nekuboora maburi pakadzika kwakaringana, uye nekuona kuti mushonga wemakemikari unoshandiswa pakuzadza magetsi unozadza maburi.

Uchishandisa ELIC tekinoroji

Iyo Dhizaini yeHDI PCBS yakatenderedza ELIC tekinoroji yakagonesa iyo dhizaini dhizaini kukudziridza yakafambira mberi PCBS, iyo inosanganisira akawanda akaturikidzana eakaunganidzwa emhangura akazadzwa microholes mune iyo pad. Nekuda kweEELIC, zvigadzirwa zvePCBB zvinogona kutora mukana wekubatana kwakakomba, kwakaomarara kunodiwa kumatunhu epamusoro-soro. Nekuti ELIC inoshandisa makobvu-akazara emhangura-akazara ekubatanidza, inogona kubatanidzwa pakati pematanho maviri pasina kushomeka bhodhi redunhu.

Chinhu chinosarudzwa chinokanganisa marongerwo

Chero kutaurirana nevagadziri uye vagadziri zvine chekuita neHDI dhizaini inofanirwa zvakare kutarisisa pamatanho chaiwo ezvinhu zvakakurisa-kuwanda. Iko kusarudzwa kwezvinhu kunokanganisa wiring upamhi, chinzvimbo, stack uye gomba saizi. Semuenzaniso, HDI pcb magadzirirwo anowanzo sanganisira dense bhora grid array (BGA) uye yakapatsanuka BGA BGA inoda pini kutiza. Zvinhu zvinokanganisa magetsi uye nekuvimbika chiratidzo pamwe nekuvimbika kwepanyama kwebhodhi zvinofanirwa kuzivikanwa kana uchishandisa izvi zvishandiso. Izvi zvinhu zvinosanganisira kuwana kusarudzika kwakakodzera pakati pematanho epamusoro uye ezasi kudzikisira kuwiriranisa crosstalk uye kudzora EMI pakati pezvikamu zvemasaini zvemukati.Symmetrically spaced zvinhu zvinobatsira kudzivirira kusaenzana kushushikana pane iyo PCB.

Teerera kune chiratidzo, simba uye kutendeka kwemuviri

Kunze kwekuvandudza kuvimbika kwemasaini, iwe unogona zvakare kuwedzera kusimba kwesimba. Nekuti iyo HDI PCB inofambisa iyo yekumisikidza padenga padyo nepamusoro, simba rekuvimbika rinovandudzwa. Denga repamusoro pebhodhi rine denderedzwa rekusimbisa uye dura rekugovera magetsi, iro rinogona kusunganidzwa kune iyo yekumisidzana nhete kuburikidza nemakomba mapofu kana microholes, uye inoderedza huwandu hwemaburi endege.

HDI PCB inoderedza huwandu hwemakomba-kuburikidza nemukati mebhodhi. Nekudaro, kudzikisa huwandu hwekuputika mundege yemagetsi kunopa zvikomborero zvitatu zvikuru:

Iyo yakakura nzvimbo yemhangura inodyisa AC uye DC yazvino muchip simba pini

L kuramba kunoderera munzira yazvino

L Nekuda kwekudzikira kwakadzika, iko iko iko kushandura ikozvino kunogona kuverenga pini yemagetsi.

Imwe poindi yakakosha yekukurukurirana ndeyekuchengetedza yakaderera tambo upamhi, yakachengeteka nzvimbo uye track yakafanana. Pane yekupedzisira nyaya, tanga kuwana yunifomu yemhangura ukobvu uye wiring zvakafanana panguva yekugadzira maitiro uye enderera neyakagadzirwa uye yekugadzira maitiro.

Kusava nenzvimbo dzakachengeteka kunogona kutungamira mukuwandisa kwemafirimu panguva yemukati yakaoma firimu maitiro, ayo anogona kutungamira kumatunhu mapfupi. Pazasi peiyo shoma dhayamita upamhi inogona zvakare kukonzera matambudziko panguva yekumachira maitiro nekuda kwekusasimba kwekutora uye yakavhurika redunhu. Dhizaina matimu uye vagadziri vanofanirwa zvakare kufunga nezvekuchengetedza njanji senzira yekudzora chiratidzo chetambo impedance.

Gadzira uye shandisa yakatarwa dhizaini mitemo

Yakakwirira-density masisitimu anoda madiki ekunze zviyero, zvakanakisa wiring uye akasimba chikamu chinzvimbo, uye nekudaro zvinoda akasiyana dhizaini maitiro. Iyo HDI pcb yekugadzira maitiro inotsamira pane laser kuchera, CAD uye CAM software, laser yakananga imaging maitiro, akasarudzika ekugadzira michina, uye opareta hunyanzvi. Kubudirira kweichi chiitiko chose kunoenderana muchikamu nemitemo yekugadzira iyo inoratidza impedance zvinodiwa, conductor upamhi, saizi gomba, uye zvimwe zvinhu zvinokanganisa marongerwo. Developing detailed design rules helps select the right manufacturer or manufacturer for your board and lays the foundation for communication between teams.
