Mumunda wemagetsi, akawanda-layer PCB (Printed Circuit Board) inoita basa rakakosha.Magadzirirwo ayo uye magadzirirwo ane simba guru pakuita uye kuvimbika kwezvigadzirwa zvemagetsi zvemazuva ano.Ichi chinyorwa chichaongorora mukati mayo akakosha maficha, magadzirirwo ekufunga, uye nzvimbo dzekushandisa kuitira kuti ipe maonero akazara.Nekuiongorora, tinogona kunzwisisa zviri nani kukosha kwayo muhunyanzvi hwemagetsi.
1, dhizaini yeakawanda-layer PCB board haisi nyore kurongedza kweakawanda single-layer mabhodhi, asi yakaoma engineering chirango.Muchikamu chekugadzira, chinhu chekutanga kufunga ndechekuoma uye kuwanda kwedunhu.Nekuenderera mberi kwekutsvaga kwekushanda muzvigadzirwa zvemagetsi zvemazuva ano, kuoma kwemaseketi kuri kuwedzerawo, saka dhizaini yayo inoda kukwanisa kuzadzisa zvinodiwa zvehupamhi hwepamusoro uye huwandu hwekushanda.Panguva imwecheteyo, zvinodiwa zvekushanda kwezvigadzirwa zvemagetsi zviri kuwedzerawo, uye dhizaini yavo inoda kuve nechokwadi kugadzikana uye kuvimbika kwekufambiswa kwechiratidzo.
2, maitiro ekugadzira akawanda-layer PCB board zvakare chikamu chakakosha.Muchikamu chekugadzira, maitiro epamberi uye matekinoroji akakosha.Nekushandisa advanced lamination tekinoroji, mhando yekubatanidza interlayer inogona kuvandudzwa kuti ive nechokwadi chekugadzikana kwekufambiswa kwechiratidzo.Uye zvakare, iyo yakakodzera kusarudzwa kwezvinhu zvakare chinhu chisingagone kufuratirwa mukugadzira maitiro, akasiyana masimidhi ekushandisa ane zvakasiyana zvinodiwa zvezvinhu, saka zvinodikanwa kusarudza zvinhu zvakakodzera zvinoenderana nechaiyo mamiriro ekushandisa mukugadzira.
3, multi-layer PCB board ine dzakasiyana siyana dzekushandisa mumunda wemagetsi.Chokutanga pane zvose, inobata basa guru muzvigadzirwa zvemagetsi zvepamusoro, zvakadai semidziyo yekukurukurirana, hardware yekombiyuta nezvimwe zvakadaro.Yayo yakakwirira density uye kugadzikana inobvumira iyi michina kuti iite zvirinani kuita zvinodiwa nevashandisi.Chechipiri, mumunda wemagetsi emotokari, zvakare inoshandiswa zvakanyanya mumotokari yemagetsi masisitimu, sekufamba, varaidzo uye zvichingodaro.Nekuda kwekuvimbika kwepamusoro uye kusimba zvinodiwa zvemagetsi emotokari, akawanda-layer PCB mabhodhi ave chinhu chakakosha.Pamusoro pezvo, yakaratidzawo zvakanakira zvayakanakira muminda yemidziyo yekurapa, kutonga kwemaindasitiri uye zvichingodaro.
Kutanga, ngatitarisei pakugadzira maitiro ePCB maviri-layer board.Kugadzirwa kwemazuva ano kwePCB kunowanzo shandisa epamusoro kemikari etching matekiniki kuti aumbe mapatani edunhu nekuvhara pateni pane yakafukidzwa nemhangura uyezve kushandisa kemikari mhinduro kukanganisa zvikamu zvisingadiwe.Iyi nzira inoda kwete chete yakakwirira-chaiyo michina, asiwo yakasimba maitiro ekutonga kuti ave nechokwadi chemhando uye kugadzikana kwebhodhi.Mukuenderera mberi kwekugadzirwa kwePCB, maitiro matsva uye zvinhu zvinoramba zvichibuda, zvichipa rubatsiro rwakasimba rwekugadzirisa kwayo kushanda.
Mumunda wekushandisa, PCB kaviri-layer board yakashandiswa zvakanyanya mumarudzi ese emidziyo yemagetsi.Kubva pamagetsi evatengi kuenda kumaindasitiri ekudzora, kubva kumidziyo yekurapa kuenda kumasisitimu ekutaurirana, inoita basa rakakosha.Kuita kwayo kwakagadzikana kwemagetsi uye kuvimbika kwakanaka kunoita kuti ive chikamu chakakosha chezvigadzirwa zvemagetsi zvemazuva ano.Panguva imwecheteyo, kushanduka kwayo kwekugadzira kunopawo mikana yakawanda yezvikumbiro zvakasiyana-siyana, kusangana nezvinodiwa zveminda yakasiyana yebhodhi.
Nekudaro, nekuenderera mberi kwehunyanzvi uye kusiyanisa zvigadzirwa zvemagetsi, izvo zvinodikanwa zvePCB maviri-layer mabhodhi zviri kuwedzera zvakare.Mune ramangwana, tinogona kutarisira mukana wepamusoro density uye chiyero chepamusoro PCB maviri-layer mabhodhi kuti asangane nezvinodiwa zvechizvarwa chitsva chemidziyo yemagetsi.Iko kuenderera mberi kwekubudirira kwehunyanzvi hwekugadzira tekinoroji uye nzira yekugadzira ichasimudzira budiriro yayo munzira yekutetepa uye yepamusoro kuita, kuvhura nzvimbo nyowani yekuvandudza mune zvigadzirwa zvemagetsi.
1. Ngativei nekunzwisisa kwakadzama kweiyo chaiyo chimiro che4-layer PCB board.
Bhodhi rinowanzove nezvikamu zviviri zvemukati conductor uye maviri akaturikidzana ekunze substrate.Iyo yemukati conductor layer ine basa rekubatanidza zvakasiyana-siyana zvemagetsi zvikamu kuti zviumbe dunhu, nepo yekunze substrate layer ichishanda setsigiro uye insulation.Iyi dhizaini inobvumira mainjiniya emagetsi kuronga zvikamu zvedunhu zviri nyore, kuvandudza kubatanidzwa uye kuita kwedunhu.
2, iyo yemaitiro mukana we4-layer PCB board ndiyo yakanaka chiratidzo chekuzviparadzanisa nevamwe kuita.
Iyo yemukati conductor layer inopatsanurwa nemagetsi ekudzivirira zvinhu, inonyatso kuparadzanisa mazinga akasiyana echiratidzo.Ichi chiratidzo chekuzviparadzanisa kwekuita kwakakosha kune yakaoma midziyo yemagetsi, kunyanya muhuwandu hwepamusoro uye yakakwirira density application.Kuburikidza nedhizaini inonzwisisika uye marongero emukati wemukati, iyo 4-layer PCB board inogona kuderedza kupindira kwechiratidzo, kuvandudza kugadzikana kwedunhu, uye kuve nechokwadi chekuvimbika. midziyo.
3, 4 layer PCB bhodhi dhizaini dhizaini zvakare inobatsira pakupisa kupisa.
Zvishandiso zvemagetsi zvinogadzira kupisa kwakawanda panguva yekushanda, uye kupisa kunoshanda kwakakosha kuchengetedza kushanda kwakajairwa kwemidziyo.Iyo 4-layer PCB board inowedzerawo thermal conductivity chiteshi nekuwedzera iyo yemukati conductor layer, iyo inobatsira kutamisa uye kubvisa kupisa.Izvi zvinobvumira michina yemagetsi kuchengetedza zvirinani tembiricha yakagadzikana panguva yekushanda kwemutoro wakakwira, kuwedzera hupenyu hwebasa remidziyo.
4, 4-layer PCB board inoitawo zvakanaka maererano newaya.
Iyo yemukati conductor layer inobvumira kune yakanyanya kuomarara uye compact wiring dhizaini, ichidzikisa nzvimbo yetsoka yedunhu.Izvi zvakakosha pakureruka uye miniaturized zvemagetsi mudziyo dhizaini.Panguva imwecheteyo, iyo yakaoma wiring dhizaini inopawo mukana wekubatanidzwa kweakasiyana anoshanda mamodules, kuitira kuti mudziyo wemagetsi uchengetedze kushanda kwakasimba kwekuita pachiri diki.
Iyo 4-layer PCB board dhizaini inoita basa rakakosha muinjiniya yemagetsi yemazuva ano, uye dhizaini yayo yakasarudzika inopa kuchinjika, kugadzikana kwekuita uye kupisa kupisa kwemidziyo yemagetsi, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa.Nekuenderera mberi kwekuvandudzwa kwesainzi uye tekinoroji, tinogona kutarisira 4-layer PCB mabhodhi kuratidza huwandu hwakakura hwemashandisirwo mune mamwe minda, zvichiunza humwe hutsva uye kubudirira kune zvemagetsi engineering.
Kutorwa pamwechete, akawanda-layer PCB board sechinhu chakakosha muhunyanzvi hwemazuva ano hwemagetsi, dhizaini nekugadzira kwayo kwakakosha.Muchikamu chekugadzirwa kwedunhu, kuoma uye kuwanda kwedunhu kunofanira kufungwa.Muchikamu chekugadzira, zvinodikanwa kushandisa maitiro epamberi uye matekinoroji uye sarudza zvinhu zvakanaka.Huwandu hwayo hwekushandisa hunovhara minda yakawanda senge kutaurirana, makomputa, uye mota, ichipa hwaro hwakasimba hwekuita uye kuvimbika kweakasiyana midziyo yemagetsi.Mune ramangwana, nekuenderera mberi kwekuvandudza tekinoroji yemagetsi, dhizaini nekugadzira kwayo icharamba ichitarisana nematambudziko matsva, asi ichapawo nzvimbo yakakura yekuvandudzwa kwemidziyo yemagetsi.
