Mumunda wemagetsi, yakawanda-layer PCB (yakadhindwa redunhu bhodhi) inoita basa rakakosha. Kugadzirwa kwayo uye kugadzirwa zvine simba rakakura pakuita uye kuvimbika kwemidziyo yemazuva ano yemagetsi. Chinyorwa ichi chinokwevera mune izvo zvakakosha zvemhando, magadzirirwo ekufunga, uye nzvimbo dzekushandisa kuitira kuti upe maonero azere. Nekuzviongorora, tinogona kunzwisisa zvirinani kukosha kwehunyanzvi hwemagetsi.
1, dhizaini yerudzi rwakawanda Muchikamu chekugadzira, chinhu chekutanga kufunga nezvekuti kuoma uye kuwedzera kwedunhu. Nekutsvaga kwekuenderera mberi kwekushanda mumidziyo yemazuva ano yemagetsi, kuoma kwematunhu kuri kuwedzerawo, saka dhizaini yacho inoda kuti igone kusangana nezvinodiwa zvekuwedzera kwakakura uye yakawanda-basa. Panguva imwecheteyo, zvinodiwa pakuita zvemidziyo yemagetsi zviri kuwedzerawo, uye dhizaini yavo inoda kuve nechokwadi chekugadzikana uye kuvimbika kwekutapurirana.
2, iyo yekugadzira maitiro e-yakawanda-layer PCB bhodhi zvakare chikamu chakakosha. Muchikamu chekugadzira, provanced maitiro uye matekinoroji akakosha. Nekushandisa tekinoroji yekuyimikira yemutemo, mhando yekubatanidza yekubatanidza inogona kunyatsogadziriswa kuve nechokwadi chekugadzikana kwekutapurirana kweSignal. Uyezve, sarudzo yakakodzera yekunyora iri zvakare chinhu chisingakwanise kufuratirwa muitiro yekugadzira, minda yakasiyana yekushandisa ine zvinodiwa zvakasiyana nemidziyo, saka zvakakosha kusarudza zvinhu zvakakodzera zvinoenderana nemamiriro ezvinhu ekushandisa mukugadzira.
3, akawanda-layer PCB bhodhi ine huwandu hwakawanda hwekushandisa mumunda wemagetsi. Chekutanga pane zvese, zvinotora chinzvimbo chakakosha mumidziyo yakakwirira yemagetsi, senge midziyo yekutaurirana, komputa hardware uye zvichingodaro. Yayo yakakwirira density uye kugadzikana kubvumira izvi zvishandiso kuti zvisangane zviri nani zvinodiwa pakuita kwevashandisi. Kechipiri, mumunda wezvemagetsi emagetsi, zvinoshandiswawo zvakanyanya mumotokari yemagetsi masisitimu, sekufamba-famba, varaidzo uye zvichingodaro. Nekuda kwekuvimbika kwakanyanya uye zvido zvekuvimbika kwezvemagetsi emagetsi, akawanda-layer PCB mabhodhi ave kuita chinhu chakakosha. Mukuwedzera, zvakaratidzawo zvakanakira zvaro zvakasarudzika muminda yemidziyo yekurapa, kudzora kwemaindasitiri uye zvichingodaro.
Kutanga, ngatitarisei pane iyo yekugadzira maitiro yePCB yakapetwa kaviri-layer mabhodhi. Yemazuva ano PCB inowana kazhinji inoshandisa nzira dzepamberi yekugadzira maitiro ekugadzira matanho ematanho nekuvhara iyo pfambi pamusoro pekupfeka uye ichishandisa mhinduro yemakemikari yekugadzirisa zvikamu zvisingadiwe. Maitiro aya anoda kwete chete zvakanyanyisa-zvigadzirwa zvekushandisa, asiwo zvakanyanyisa maitiro ekutonga kuve nechokwadi chekuti mhando uye kugadzikana kwebhodhi. Mukukura kuri kuenderera kwePCB Kugadzira, matsva maitiro uye zvigadzirwa zvinoramba zvichikwira, zvichipa rutsigiro rwakasimba rwekuvandudza kwayo kwekuita.
Mumunda wekushandisa, PCB kaviri-layer bhodhi rave kushandiswa zvakanyanya mumarudzi ese emidziyo yemagetsi. Kubva kune vatengi vezvemagetsi ekudzora maindasitiri, kubva pamidziyo yekurapa kune masisitimu ekukurukurirana, anoita basa rakakosha. Kuita kwayo kwaro kwakagadzikana kwemagetsi uye kuvimbika kwakanaka kunoita kuti ive yakakosha chikamu chezvigadzirwa zvemazuva ano zvemagetsi zvemagetsi. Panguva imwecheteyo, mafambiro aro ekugadzira anopawo mukana wekushandiswa kwakasiyana-siyana, kusangana nezvinodiwa zvevakasiyana eminda yebhodhi.
Nekudaro, neyekuenderera mberi kwehunhu uye kukonzeresa zvigadzirwa zvemagetsi, izvo zvinodiwa zvePCB kaviri-layer mabhodhi ari kuwedzerawo. Mune ramangwana, isu tinogona kutarisira mukana wekuwedzera kwakakwirira uye hwakakwira hweki-cows-layer mabhodhi kuti tisangane nezvinodiwa zvechizvarwa chitsva chemidziyo yemagetsi. Iyo inoramba ichibudirira yeTekinoroji yeTekinoroji uye yekugadzira maitiro ichakurudzira kukura kwayo munzira yekufambisa uye kuita kwakakwirira, kuvhura nzvimbo itsva yekuvandudza zvigadzirwa zvemagetsi.
1. Ngativei nekunzwisisa kwakadzama kweiyo chaiyo chimiro cheiyo 4-layer PCB Bhodhi.
Bhodhi rinowanzove rine zvikamu zviviri zvemukati memukati uye maviri zvikamu zvechikamu chekunze. Iyo yekuita yemukati yekuitisa ine mutoro wekubatanidza zvikamu zvakasiyana zvemagetsi kuti aumbe mudunhu, nepo iyo yekunze substrate layer sechitsigiro uye chipenga. Dhizaini iyi inobvumira magetsi maine mainjiniya kuronga zvikamu zvechitunha zvakanyanya, achivandudza kuwirirana uye kuita kwedunhu.
2, mukana wekugadzirisa we4-layer PCB board ndiyo chiratidzo chayo chakanaka seyisipiso yekuita.
Iyo yekutaurirana yemukati inotaura yakaparadzaniswa neyemagetsi insulation zvinhu, zvinoparadzanisa zvinowirirana nemazinga akasiyana eSignal. Ichi chiratidzo chekusarudzika kwekusarudzika kwechiitiko chakaomesesa zvemagetsi zvemagetsi, kunyanya mune yakakwira frequence
3.
Zvivakwa zvemagetsi zvinounza kupisa kwakawanda panguva yekushanda, uye zvinoshanda zvinopisa zvinopisa kuti uchengetedze kushanda kwakajairika kwemidziyo. Iyo 4-layer PCB Bhodhi zvakare inowedzerawo iyo inowedzera conders chiteshi nekuwedzera iyo yemukati conductor layer, inobatsira kuendesa uye kusundira kupisa. Izvi zvinobvumira zvishandiso zvemagetsi kuti zvirambe zvakanaka tembiricha panguva yekushambadzira yakakwira, kuendesa hupenyu hwebasa hwemidziyo.
4, 4-layer PCB Bhodhi zvakare inoita zvakanaka maererano ne wiring.
Iyo yekuita yemukati inotungamira inobvumira kune yakaomarara uye compact wiring wire dhizaini, kuderedza nzvimbo yenzvimbo yedunhu. Izvi zvakakosha pakuremedza uye miniaturized emagetsi emagetsi dhizaini. Panguva imwecheteyo, dhizaini yakaoma yekuita kuti iwane mukana wekubatanidzwa kwemasangano akasiyana-siyana ekushanda, kuitira kuti mudziyo wemagetsi unogona kuchengetedza kushanda kwakasimba paunenge uri mudiki.
Iyo 4-Layer PCB Board Statures inoita basa rakakosha muinjiniya yemazuva ano, uye kugadzikana kwemabasa ekuita uye kupisa kwemidziyo yemagetsi, zvichiita kuti ive yakanaka kune dzakasiyana siyana dzekushandisa. Nekukura kwekuenderera kwesainzi uye tekinoroji, tinogona kutarisira 4
Kutorwa pamwe chete, multi-layer-layer-bhodhi bhodhi seyakakosha chikamu mune zvemazuva ano zvemagetsi tekinoroji, dhizaini yacho uye kugadzira kwakakosha. Mudunhu redunhu dhizaini, kuomarara uye kusimba kwedunhu kunofanirwa kutariswa. Muchiitiko chekugadzira, zvinodikanwa kuti ushandise maitiro epamberi uye matekinoroji uye sarudza zvinhu zvakanaka. Zvakawanda zvakasiyana-siyana zvekushandisa zvinovhara minda yakawanda senge kutaurirana, makomputa, nemotokari, kupa hwaro hwakasimba hwekuita uye kuvimbika kwemidziyo dzakasiyana siyana zvemagetsi. Mune ramangwana, nekukura kusingaperi kwehunyanzvi hwemagetsi, dhizaini yayo uye kugadzira icharamba ichisangana nematambudziko matsva, asi ichapawo nzvimbo yakakura yekuvandudzwa kwemidziyo yemagetsi.
