Kune nzvimbo zhinji mukatiPCB DhizainiIko kwakachengeteka kupatsanurwa kunoda kufungwa nezvazvo. Pano, inoonekwa kwenguva pfupi mumapoka maviri: Imwe ndeyekuchengetedza kwemagetsi kuchengetedzeka, imwe ndeye isiri-yemagetsi yakachengetedzeka kuchengetedza.
Yemagetsi yakanangana nekuchengetedza kuchengetedza
1.Spacing pakati waya
Kusvika pakugadzirisa kugona kweiyo huruPCB Vagadziriane hanya, kushoma kushoma pakati pemawaira hakuzove kushoma pane 4mil. Iyo shoma waya waya kure kure zvakare kure neya waya kusvika waya waya uye waya kusvika pad. Kubva pamaonero ekugadzira, izvo zvakakura zviri nani kana zvichibvira, uye 10mil chidimbu.
2.pad Aperture uye Pad upamhi
Panyaya yekugadzirisa huwandu hwenzvimbo huru PCB Vagadziri, iyo yekushambadzira iyo Pad haifanire kunge iri pasi pegumi ne2.2mm kana ichinge yadhirowa, uye 4mil kana iri laser ichirova. Kushivirira kwekushivirira kwakasiyana zvishoma zvinoenderana neplate, kazhinji kunogona kudzorwa mukati me005mm, iyo yakaderera yehupamhi yePad haifanire kunge iri pasi pe0.2mm.
3.scaping pakati pePad
Kusvika pakugadzirisa kugona kweiyo mainstream pcb Vagadziri vane hanya, kupatsanurana pakati pemapuru hakuzove kwakaderera 0.2mm.
4.Here kure pakati pemhangura nemupendero webhokisi
Kupatsanurana pakati peganda rakapomedzerwa renzvimbo uye mupendero wePCB Bhodhihaifanire kunge isingasviki 0,3mm. Pane dhizaini-yemitemo-bhodhi redline peji, isa mutemo wekuparadza wechinhu ichi.
Kana nzvimbo yakakura yemhangura yarongwa, pane kazhinji inodonha chinhambwe pakati pemapuranga uye nemucheto, iyo inowanzoiswa kusvika 20mil. MuPCB Dhizaini uye Indasitiri Yemamiriro ezvinhu, nekuda kwekufunga kweiyo pamucheto wedunhu, kana kuti kudzivisa nzvimbo yemucheto kwemhete, pane ganda renzvimbo, pane ganda remhangura rakapararira kumucheto kwebhodhi.
Iyi mhangura isingabatanidzwe nenzira dzakasiyana siyana, dzakadai sekudhirowa denderedzwa renzvimbo pamucheto weplate, wobva waisa chinhambwe pakati pemhangura uye keopote. Nzira yakapusa inounzwa pano, kureva kuti, madaro ekuchengetedza ekuchengetedza anoiswa kune iyo mhangura yekuisa zvinhu. Semuenzaniso, chinhambwe chakachengetedzeka chebhodhi rose racho rwakagadzirirwa 10mil, uye iyo mhangura yakaiswa kusvika 20mil, iyo inogona kuwana mhedzisiro yekupedzisa 20mil mukati memupendero webhodhi uye bvisa iyo inogona kunge yakafa yemhangura yemhangura mudziyo.
Isiri-yemagetsi yakanangana nekuchengetedza nzvimbo
1. Hunhu hwakafara, kukwirira uye kupatsanura
Hapana shanduko dzinogona kuitwa mukugadziriswa kweiyo firimu, asi upamhi hwemitsetse yevatambi pazasi 0.22mm (.
Upamhi hwehunhu hwese hwacho w = 1.0mm, kukwirira kwehunhu hwese h = 1.2mm, uye kupatsanurwa pakati pemavara ndeye d = 0.2mm. Kana iwo mavara ari pasi peiyo iri pamusoro standard, kudhinda kudhinda kuchavezwa.
2.pacing pakati peVias
Iyo kuburikidza-gomba (kuburikidza ne-kuburikidza ne-gomba kupatsanura (mupendero kusvika pamucheto) zvinofanirwa kunyanya kuve zvakakura kupfuura 8mil
3.Distance kubva ku screen kudhinda kudhirowa
Kudhinda kweScreen hakubvumirwi kuvhara iyo pad. Nekuti kana iyo skrini yekudhinda yakafukidzwa neyetengesa pad, iyo skrini yekudhinda haizove pane tini kana iyo tini iri pamusoro, iyo ichakanganisa chikamu chichiwedzera. Iyo General Bhodhi fekitori inoda kuti 8mil sparting ichengetwe zvakare. Kana iyo PCB Bhodhi ishoma munzvimbo, 4mil spading haagamuchirwe. Kana iyo skrini yekudhinda yakafukidzwa neyakafukidzwa pane iyo Pad panguva yekugadzira, iyo plate fekitari inobvisa iyo yekudhinda yekudhinda pane iyo Pad panguva yekugadzira kuti ioneke tini pad.
Ehe, inyaya-ne-kesi nzira panguva yekugadzira nguva. Dzimwe nguva iyo Screen Dhinda inochengetwa nemaune padanho, nekuti mapato maviri aya ari padhuze neyekupedzisira ari pakati nepakati anogona kudzivirira mutengesi kiripfupi dunhu panguva yeWelding, ndeipi imwe nyaya.
4.Mechanical 3D kureba uye yakatwasuka kupatsanura
Kana uchiisa zvikamu panePCB, zvinodikanwa kuti ufunge kana nhungamiro yakatwasuka uye kukwirira kwenzvimbo kuchapesana nezvimwe michina manhamba. Naizvozvo, mukugadzirwa, isu tinofanirwa kufunga zvizere kuwirirana pakati pezvikamu, pakati pePCB zvakazara zvigadzirwa uye chigadzirwa shell, uye chengetedza kupatsanurwa kwechimwe nechimwe chinhu chekutanga kuona kuti hapana kupokana munzvimbo.
