Iko kukurumidza kuvandudza kwemagetsi tekinoroji kwakaitawo kuti zvigadzirwa zvemagetsi zvirambe zvichienda kune miniaturization, kuita kwepamusoro uye kuwanda-kushanda. Sechinhu chakakosha chezvigadzirwa zvemagetsi, kushanda uye kugadzirwa kwemapuranga edunhu kunobata zvakananga kunaka uye kushanda kwechigadzirwa chose. Mabhodhi edunhu echinyakare kuburikidza negomba ari kutarisana nezvipingamupinyi zvishoma nezvishoma mukusangana nezvinodiwa zvakaoma zvemidziyo yemagetsi yemazuva ano, saka iyo yakawanda-layer chimiro dhizaini yeHDI bofu uye yakavigwa kuburikidza nemabhodhi edunhu yakabuda sezvinodiwa nenguva, ichiunza mhinduro nyowani kumagetsi edunhu dhizaini. Nemagadzirirwo ayo ega ega maburi mapofu uye maburi akavigwa, zvakatosiyana nemabhodhi echinyakare kuburikidza nemaburi. Inoratidza mabhenefiti akakosha muzvinhu zvakawanda uye ine simba rakadzika pakuvandudzwa kweindasitiri yemagetsi.
一、 Kuenzanisa pakati peakawanda-layer chimiro dhizaini yeHDI bofu uye yakavigwa kuburikidza nemabhodhi edunhu uye kuburikidza-gomba mabhodhi.
(一) Hunhu hwekupfuura-gomba bhodhi chimiro
Traditional through-hole circuit boards ane through-maburi akaboorwa mukati mehukobvu hwebhodhi kuti awane kubatanidza magetsi pakati pematanho akasiyana. Iyi dhizaini iri nyore uye yakananga, uye tekinoroji yekugadzira inenge yakakura. Nekudaro, kuvepo kwemaburi-maburi kunotora nzvimbo yakakura uye kunodzikamisa wiring density. Kana chidimbu chepamusoro chekubatanidza chichidiwa, ukuru uye nhamba ye-maburi-maburi zvichakanganisa zvakanyanya wiring, uye mu-high-frequency signal transmission, kuburikidza-maburi anogona kuunza mamwe maratidziro ezviratidzo, crosstalk uye mamwe matambudziko, anokanganisa kutendeseka kwechiratidzo.
(二) HDI bofu uye kuvigwa kuburikidza nedunhu bhodhi akawanda-layer chimiro dhizaini
HDI mapofu uye akavigwa kuburikidza nemabhodhi edunhu anoshandisa dhizaini yakanyanyisa. Blind vias ndiwo makomba kuti batanidza kubva okunze pamusoro kuti chaiyo yomukati akaturikidzana, uye havaiti kumhanya yose redunhu bhodhi. Akavigwa vias maburi kuti batanidza yomukati akaturikidzana uye regai kuwedzera kusvika pamusoro redunhu bhodhi. Iyi dhizaini yakawanda-yakapetwa dhizaini inogona kuwana nzira dzakaomarara dze wiring nekuronga zvine musoro zvinzvimbo zvemapofu uye akavigwa vias. Mune multi-layer board, zvidimbu zvakasiyana zvinogona kubatanidzwa nenzira yakanangwa kuburikidza nebofu uye yakavigwa vias, kuitira kuti masaini anogona kufambiswa zvakanaka munzira inotarisirwa nemugadziri. Semuyenzaniso, nokuda mana-layer HDI bofu uye akavigwa kuburikidza redunhu bhodhi, rokutanga uye rechipiri akaturikidzana anogona kwakabatana kuburikidza nemapofu vias, rechipiri uye rechitatu akaturikidzana anogona kwakabatana kuburikidza akavigwa vias, uye zvichingodaro, izvo zvikuru kunonatsiridza kuchinjika. wiring.
二、Zvakanakira HDI bofu uye kuvigwa kuburikidza nedunhu bhodhi multi-layer chimiro dhizaini
(一,) Higher wiring density Sezvo mapofu uye akavigwa vias haadi kutora yakawanda nzvimbo senge kuburikidza-makomba, HDI bofu uye kuvigwa kuburikidza redunhu mapuranga anogona kuwana akawanda wiring munzvimbo imwe chete. Izvi zvakakosha zvakanyanya kune inoenderera miniaturization uye inoshanda kuoma kwezvinhu zvemazuva ano zvigadzirwa zvemagetsi. Semuenzaniso, mumadiki madiki emafoni akadai sema smartphones uye mahwendefa, nhamba huru yezvigadzirwa zvemagetsi uye masekete zvinoda kubatanidzwa munzvimbo shoma. Iyo yakakwira wiring density mukana weHDI bofu uye yakavigwa kuburikidza nemabhodhi edunhu inogona kuratidzwa zvizere, iyo inobatsira kuwana yakawedzera compact yedunhu dhizaini.
(二、) Zvirinani chiratidzo chekuvimbika Panyaya ye-high-frequency signal transmission, HDI bofu uye kuvigwa kuburikidza nemabhodhi ematunhu anoita zvakanaka. Dhizaini yemapofu uye yakavigwa vias inoderedza kutarisisa uye crosstalk panguva yekufambisa kwemasaini. Zvichienzaniswa nemabhodhi epaburi, masaini anogona kushandura zvakanyanya pakati pezvikamu zvakasiyana muHDI bofu uye kuvigwa kuburikidza nemabhodhi edunhu, kudzivirira kunonoka kwechiratidzo uye kukanganisa kunokonzerwa neakareba simbi mbiru maitiro epaburi-maburi. Izvi zvinogona kuve nechokwadi chekufambisa data kwakaringana uye nekukurumidza uye kuvandudza mashandiro ehurongwa hwese hwemamiriro ekushandisa akadai se5G yekutaurirana mamodule uye akakwira-kumhanya processors ane zvakanyanyisa zvinodikanwa zvechiratidzo chemhando.
(三、) Kuvandudza mashandiro emagetsi Iyo yakawanda-layer chimiro cheHDI bofu uye yakavigwa kuburikidza nemabhodhi edunhu inogona kudzora zvirinani kukanganiswa kwedunhu. Nekunyatso gadzira maparameter emapofu uye akavigwa vias uye dielectric ukobvu pakati pezvikamu, iyo impedance yeimwe dunhu inogona kugadziridzwa. Kune mamwe maseketi ane zvakaomesesa impedance yekufananidza zvinodiwa, seredhiyo frequency maseketi, izvi zvinogona kunyatso kudzikisa zviratidzo zvechiratidzo, kunatsiridza kutapurirana kwemagetsi kushanda zvakanaka, uye kuderedza kukanganiswa kwemagetsi, nekudaro zvichivandudza mashandiro emagetsi edunhu rese.
四、 Yakavandudzwa dhizaini inochinjika Vagadziri vanogona kuchinjika dhizaini nzvimbo uye nhamba yemapofu uye yakavigwa vias zvichibva pane chaiyo yedunhu inoshanda zvinodiwa. flexibility ichi haingoratidzwi chete mu wiring, asi inogonawo kushandiswa optimize simba kuparadzirwa network, pasi ndege marongerwo, etc. Somuenzaniso, simba akaturikidzana uye pasi rukoko zvinogona zvine musoro kwakabatana kuburikidza bofu uye akavigwa vias kuderedza simba rekupa ruzha, kunatsiridza kugadzikana kwemagetsi, uye siya yakawanda wiring nzvimbo kune mamwe masaini mitsara kusangana akasiyana dhizaini zvinodiwa.
Iyo yakawanda-layer chimiro dhizaini yeHDI bofu uye yakavigwa kuburikidza nedunhu bhodhi ine yakatosiyana dhizaini dhizaini kubva kune kuburikidza-gomba bhodhi, ichiratidza zvakakosha muhukuru hwe wiring density, kusarongeka kwechiratidzo, kuita kwemagetsi uye dhizaini inoshanduka, nezvimwewo, uye i mazuva ano Kuvandudzwa kweindasitiri yemagetsi kunopa rutsigiro rwakasimba uye kunokurudzira zvigadzirwa zvemagetsi kuti zvive zvidiki, nekukurumidza, uye zvakanyanya kugadzikana.
