Musiyano mukuru pakati peHDI nePCB yakajairika - nguva itsva yekubatana kwehuwandu hwakawanda
HDI (High Density Interconnection) ibhodhi redunhu rakagadzirwa nevashandisi vane vhoriyamu shoma. Kana tichienzanisa nemaPCB akajairwa, chinhu chakakosha cheHDI ndechekuti ine waya yakawanda. Musiyano uripo pakati pezviviri izvi unonyanya kuratidzwa muzvikamu zvina zvinotevera.
1. HDI idiki uye yakareruka pakurema
Mabhodhi eHDI akagadzirwa nemabhodhi echinyakare ane mativi maviri semabhodhi makuru uye anonamirwa ne continuous lamination. Rudzi urwu rwemabhodhi edunhu akagadzirwa ne continuous lamination anonziwo Build-up Multilayer board (BUM). Kana tichienzanisa nemabhodhi edunhu echinyakare, maHDI ane zvakanakira zvekuti "akareruka, matete, mapfupi, uye madiki".
Kubatana kwemagetsi pakati pemabhodhi eHDI kunowanikwa kuburikidza nekuisa maburi anofambisa mhepo, akavigwa/asingaonekwe kuburikidza nekubatanidza. Maumbirwo awo akasiyana nemabhodhi ecircuit ane maburi akawanda. Mazhinji ema micro-buried/blind vias anoshandiswa mumabhodhi eHDI. HDI inoshandisa laser direct drilling, nepo standard PCB inowanzo shandisa mechanical drilling, saka huwandu hwema layers uye aspect ratio zvinowanzo deredzwa.
2. Maitiro ekugadzira motherboard yeHDI
Kuwanda kwemabhodhi eHDI kunonyanya kuratidzwa nekuwanda kwemaburi, mitsetse, mapedhi, uye ukobvu hwepakati pezvikamu.
Maburi madiki: Bhodhi reHDI rine magadzirirwo emaburi madiki akadai semaburi madiki, ayo anonyanya kuratidzwa muhunyanzvi hwekugadzira maburi madiki ane dhayamita iri pasi pe150um uye zvinodiwa zvakanyanya maererano nemutengo, kushanda zvakanaka kwekugadzira uye kutonga kwakarurama kwenzvimbo yemaburi. Kune maburi madiki chete mumabhodhi echinyakare ane layer circuit uye hapana maburi madiki akavigwa/asina mapofu.
Kugadziriswa kwehupamhi/nzvimbo yemutsara: Izvi zvinonyanya kuratidzwa mukuwedzera kwezvinodiwa zvezvikanganiso zvemutsara uye kuomarara kwenzvimbo yemutsara. Kazhinji, hupamhi/nzvimbo yemutsetse hahufanirwe kudarika 76.2um.
Kuwanda kwepad: huwandu hwekubatana kwe soldering hwakakura kupfuura 50/cm2
Kutetepa kweukobvu hwe dielectric: Izvi zvinonyanya kuratidzwa mumafambiro eukobvu hwe dielectric pakati pema layer kusvika 80um uye pasi, uye zvinodiwa zvekuenzana kweukobvu zviri kuramba zvichiwedzera kuoma, kunyanya kumabhodhi ane density yakakura uye substrates dzekurongedza dzine hunhu hwe impedance control.
3.Kushanda kwemagetsi kwebhodhi reHDI kuri nani
HDI haingogonese chete kuti magadzirirwo ezvigadzirwa zvekupedzisira ave madiki, asiwo inosangana nezvinodiwa zvepamusoro zvekushanda kwemagetsi uye kushanda zvakanaka.
Kuwedzera kwehuwandu hweHDI hunobatanidza masaini kunoita kuti masaini awedzere simba uye kuvimbika kwawo kuve kwakasimba. Pamusoro pezvo, maHDI board ane kuvandudzwa kuri nani mukukanganiswa kweRF, kukanganiswa kwemafungu emagetsi, kubudiswa kwemagetsi, kufambiswa kwekupisa, nezvimwewo. HDI inoshandisawo tekinoroji yakazara yedhijitari (DSP) uye matekinoroji akati wandei ane patent, ine mukana wekugadzirisa mutoro wemagetsi uye kugona kwenguva pfupi kudzoreredza simba.
4. Mabhodhi eHDI ane zvinodiwa zvakanyanya zvekuvhara kuburikidza nekubatanidza.
Ingava saizi yebhodhi kana mashandiro emagetsi, HDI iri nani pane PCB yakajairika. Mari yega yega ine mativi maviri. Rumwe rutivi rweHDI nderekuti sezvo ichigadzirwa sePCB yepamusoro-soro, muganho wayo wekugadzira uye kuoma kwemaitiro kwakakwira zvakanyanya kupfuura kwePCB yakajairika. Kunewo nyaya dzakawanda dzinofanira kutariswa panguva yekugadzira - kunyanya dzakavigwa kuburikidza nekubatanidza.
Parizvino, dambudziko guru uye kuoma kwekugadzira HDI kunovigwa kuburikidza nekubatanidza. Kana HDI yakavigwa isina kuvharwa zvakanaka, matambudziko makuru emhando yepamusoro anomuka, kusanganisira mipendero yebhodhi isina kuenzana, ukobvu hwe dielectric husina kuenzana, uye mapitted pads, nezvimwewo.
Pamusoro pebhodhi hapana kuenzana uye mitsetse haina kutwasuka, zvichikonzera mamiriro ekunze ari mugungwa, izvo zvinogona kukonzera zvikanganiso zvakaita semigero yemitsetse uye kupatsanurwa kwemiganhu.
Kusagadzikana kwehunhu kuchachinjawo nekuda kwehukobvu hwe dielectric husina kuenzana, zvichikonzera kusagadzikana kwechiratidzo.
Kusaenzana kwepedhi rekusonesa kuchaita kuti pave nemhando isina kunaka yekurongedza uye kurasikirwa kwezvikamu zvinotevera.
Saka, havasi vese vagadziri vePCB vane kugona nesimba rekuita basa rakanaka paHDI. Neruzivo rwemakore anopfuura makumi maviri mukugadzira maPCB, RICHPCBA inopa matekinoroji ekugadzira mabhodhi edunhu akadhindwa uye mwero wepamusoro-soro weindasitiri yezvemagetsi. Zvigadzirwa zvinosanganisira: 1-68 layers PCB, HDI, multilayer PCB, FPC, rigid pcb, flex pcb, rigid-flex pcb, ceramic pcb, high frequency pcb, nezvimwewo. Sarudza RICHPCBA semugadziri wako wePCB akavimbika muChina.
