Dhizaini ye Pcb bhodhi anowanzove nematambudziko akadaro neakadai? Nhasi ndinoda chirongwa che network xiaobian chakakurudzira ichi chinyorwa chiri kuita pcb bhodhi dhizaini kwemakore mazhinji einjiniya, akadhindwa wedunhu bhodhi dhizaini yekugovana newe. Welcome to unganidza!

Zvemagetsi zvigadzirwa, pcb bhodhi dhizaini inofanirwa dhizaini dhizaini kubva kumagetsi schematic dhayagiramu kune chimwe chigadzirwa, uye kufunga kweyakagadzirwa kwakabatana zvakanyanya nekugadzirwa kwechigadzirwa uye mhando yechigadzirwa. Nekudaro, kune vanhu vazhinji vari kungoita zvemagetsi dhizaini, ivo vane zvishoma ruzivo mune izvi chinhu. Kunyangwe ivo vakadzidza pcb board dhizaini software, Asi pcb magadzirirwo anowanzo kuve nemamwe matambudziko. Injiniya yakakurudzirwa naXiaobian ave achishanda muPCBboard dhizaini kwemakore mazhinji. Iye / iye achagovana yake / yake ruzivo mune PRINTED redunhu bhodhi dhizaini newe, achitarisira kutamba chinzvimbo chekukanda chidhinha kukwezva jade. Iyo PCB dhizaini software yakakurudzirwa nainjiniya yaive TANGO makore mashoma apfuura, uye ikozvino inoshandisa PROTEL2.7 YEMAWHURE.

PCB mamisirwo

Iwo akajairwa kurongeka kwekuiswa kwezvinhu paPCB:

1, isa zvinhu zvine chinzvimbo chakamiswa padhuze nechimiro, senge magetsi soketi, mwenje wechiedza, switch, chinongedzo, nezvimwe, zvinhu izvi zvinoiswa mushure meKUSVIRA basa kwesoftware kuti RIKANGANWE, kuitira kuti risazombove kutamiswa nekukanganisa;

2, yakasarudzika zvikamu uye hombe zvikamu zvakaiswa pamutsetse, senge kupisa zvinhu, maTransformer, IC, nezvimwe.

3. Isa tumidziyo tudiki.

Kureba pakati pechinhu uye kumucheto kwePCB

Kana zvichibvira, zvese zvinoriumba zvinofanirwa kuiswa mukati me3mm kubva pamucheto webhodhi rePCB kana zvirinani zvakakura kupfuura pakukora kwebhodhi rePCBB. Izvi zvinodaro nekuti mukugadzirwa kwakawanda kwegungano mutsetse plug-ins uye wave soldering, inofanirwa kupihwa kune inotungamira groove yekushandisa. Panguva imwecheteyo, kuitira kudzivirira kukanganisa kwemupendero kunokonzerwa nekugadzirisa chimiro, kana paine zvakawanda zvakawandisa pane pcb board, Kana iwe uchifanira kuenda kupfuura iyo 3mm renji, iwe unogona kuwedzera 3mm yebetsero mupendero kumucheto kwebhodhi rePCB, uye vhura slot yakaita-V pamucheto webetsero, iyo inogona kuputswa neruoko panguva yekugadzirwa.

Kuzviparadzanisa pakati pekukwirira uye kwakadzika kumanikidza

Iko kune yakakwira magetsi wedunhu uye yakaderera magetsi wedunhu panguva imwe chete pane akawanda maPCB mabhodhi, izvo zvikamu zveiyo yakakwira voltage wedunhu uye yakaderera magetsi chikamu chinofanira kupatsanurwa uye kuvhurika, uye iyo yekuzviparadzanisa daro ine chekuita nekumira voltage. Kazhinji, pcb pabhodi inofanirwa kunge iri 2mm kure nemhepo inomira pa2000kV, uye chikamu chiri pamusoro peichi chinofanira kuwedzerwa, semuenzaniso, kana muyedzo wemagetsi bvunzo uri 3000V, Iyo nhambwe iri pakati penzvimbo dzakakwirira uye dzakaderera magetsi mitsara inofanirwa kuve inopfuura 3.5mm, muzviitiko zvakawanda kudzivirira kukwira, asiwo mubhodhi rePCB pakati penzvimbo yepamusoro neyepasi yemagetsi.

Pcb bhodhi cabling

Kurongeka kweakadhindwa makondakita kunofanirwa kuve kupfupi sezvinobvira, kunyanya mumatunhu epamusoro maseketi; Iko kutendeuka kwetambo yakadhindwa kunofanirwa kukomberedzwa, uye Angle chaiyo kana Angle yakapinza inokanganisa mashandiro emagetsi mune yepamusoro frequency frequency uye wiring density; Kana uchibatanidza mapaneru maviri, waya pamativi ese ari maviri anofanirwa kuve akaenzana, oblique, kana akakotama kuti arege kufanana kune mumwe nemumwe kudzikisa kubatana kweparasiti. Wiring dzakadhindwa dzinoshandiswa seyakapinza uye kubuda kwetunhu dzinofanirwa kudzivirirwa dzakaenzana kune imwe neimwe pazvinogona kudzivirira mhinduro. Zviri nani kuwedzera waya dzekumisikidza pakati peaya waya.

Upamhi waya yakadhindwa

Hupamhi hwetambo hunofanirwa kusangana nezvinodiwa pakuita kwemagetsi uye kuve nyore kugadzirwa. Kukosha kwayo kushoma kunoenderana nesaizi yezvino, asi hushoma haufanire kunge uri pasi pe0.2mm. Muhupamhi hwepamusoro, yakanyanya kunyatsodhindwa mitsara, waya upamhi uye nzvimbo inowanzo kuve inodiwa 0.3mm; Iko tembiricha inomuka yehupamhi hwetambo inofanirwa kutariswa mune yekukwirira kwazvino. Iyo imwechete-pani yekuyedza inoratidza kuti kana pakukora kwemhangura foil iri 50μm, hupamhi hwetambo iri 1 ~ 1.5mm uye yazvino iri 2A, tembiricha inomuka idiki kwazvo. Naizvozvo, iyo waya ine upamhi hwe1 ~ 1.5mm inogona kusangana nezvinodiwa dhizaini pasina kukonzera tembiricha kusimuka.

Tambo dzakajairika dzepasi dzevatyairi vakadhindwa dzinofanirwa kunge dzakakora sezvinobvira, vachishandisa mitsara yakakura kudarika 2 kusvika 3mm kana zvichibvira, kunyanya mumatunhu ane microprocessors. Nekuti iyo yemuno tambo yakanyanyisa kunaka, nekuda kweshanduko yekuyerera kwazvino, ivhu ingangoita shanduko, microprocessor nguva yekukwirisa chiratidzo padanho kusagadzikana, ichaita ruzha rwekushivirira ruzha; Iyo 10-10 uye 12-12 misimboti inogona kushandiswa kana wiring pakati peDIP yakarongedzwa IC pini, ndiko kuti, kana tambo mbiri dzikapfuudzwa pakati pembambo, iyo padhi dhayamita inogona kumisikidzwa ku50mil, mutsara upamhi uye mutsetse spacing ari 10mil, apo waya imwe chete inopfuudzwa pakati pembambo, iyo padhi dhayamita inogona kumisikidzwa ku64mil, mutsara upamhi uye mutsetse spacing ari 12mil.

Kupatsanurwa kwewaya dzakadhindwa

Musiyano uripakati pewaya dziri padhuze unofanirwa kusangana nezvinodiwa zvekuchengetedza magetsi, uye kuitira kuti mashandiro nekugadzirwa zvivepo, nzvimbo yacho inofanira kunge yakafara sezvinobvira. Nzvimbo shoma inofanirwa kuve inokodzera kuti voltage isimbiswe. Iyi voltage inowanzo sanganisira iyo inoshanda voltage, iyo yekuwedzera yekuchinja magetsi uye iyo yepamusoro voltage inokonzerwa nezvimwe zvikonzero.

Kana mamiriro ehunyanzvi akabvumidza imwe nhanho yesimbi yakasara pakati pewaya, nzvimbo yacho inoderedzwa. Mugadziri saka anofanira kufunga nezveichi chinhu kana achifunga nezvemagetsi. Kana wiring diki iri yakaderera, iyo nzvimbo yemasaini inogona kuwedzera nenzira kwayo, tambo yemasaini nekusaenzana kukuru kwepamusoro, yakaderera nhanho inofanirwa kuve ipfupi kusvika pazvinogona uye kuwedzera nzvimbo.

Kudzivirirwa uye kumisikidzwa kwewaya akadhindwa

Iyo yeruzhinji pasi tambo yeiyo yakadhindwa waya ichave yakarongedzwa kumucheto kwebhodhi rakadhindwa redunhu bhodhi kusvika pazvinogoneka. Yakawanda mhangura foil sezvinobvira inofanirwa kuchengetwa seye waya yepasi pabhodhi rePCB, kuitira kuti iko kudzivirirwa kuri nani kupfuura tambo refu yepasi, hutachiona hutambo hunhu uye yekudzivirira mhedzisiro ichavandudzwa, uye zvakare inoita basa mukuderedza iyo yakagovaniswa capacitance. Terevhizheni yepasi tambo yetambo yakadhindwa yakanyanya kunaka kugadzira chiuno kana netiweki, nekuti kana paine akawanda macircuit akabatanidzwa pane imwechete bhodhi, kunyanya kana paine zvinhu zvinodya simba rakawanda, muganho uri pagrafu unoburitsa mukana wepasi, izvo izvo inokonzeresa kudzikiswa kweruzha kushivirira, kana chikaita chiuno, iyo yekumisikidza ingangoita mutsauko inoderedzwa.

Uye zvakare, pasi uye dhayagiramu yemagetsi inofanirwa kunge ichienderana nekutenderera kwekutenderera kwedata kusvika pazvinogoneka, chinova chakavanzika chekusimudzira ruzha kudzvinyirira kugona; Multilayer pcb bhodhi inogona kutora akati wandei matanda senge inodzivirira dura, magetsi magetsi, pasi pevhu inogona kutaridzwa senge inodzivirira dura, yakajairwa ivhu dura uye simba denderedzwa zvakagadzirwa mune yemukati nongedzo yemultilayer pcb bhodhi, chiratidzo mutsara dhizaini yemukati nhete uye yekunze dura.
