PCB kopi bhodhi, indasitiri inowanzotaurwa seDunhu repabhodhi yebhodhi, redunhu rechiratidzo

Ndokunge, pane zvivakwa zvekuti pane zvinhu zvepanyama zvezvigadzirwa zvemagetsi uye zvimedu zvematunhu, Bumbiro rezvinyorwa zveCommunity,

Wobva washandisa aya mafaera ehunyanzvi uye mafaera ekugadzira yePCB Kugadzirwa, chikamu cheProping probe kuyedza, redunhu board docling, uye zadzisa kopi yakazara yedunhu repakutanga wedunhu rekutanga.

Vanhu vazhinji havazivi kuti PCB Copy Bhodhi ndeye. Vamwe vanhu vanofunga kuti PCB kopi bhodhi ndeye kopi.

Mukunzwisisa kwemunhu wese, kopi zvinoreva kutevedzera, asi PCB Copy Bhodhi ndeyechokwadi isiri kutevedzera. Chinangwa chePCB Copy bhodhi ndeyekufunda iyo yazvino Electronic Circuicit tekinoroji, uye wobata zvakanaka dhizaini yekugadzira mhinduro, uye wobva washandisa iyo kukudziridza magadzirirwo ari nani. Chigadzirwa.

Nekukura kwekuenderera mberi uye nekudzikisira kwekopi yekodhi indasitiri, nhasi PCB yeBhodi rutivi rwakawedzerwa mumatunhu ekutevedzera uye kuvhara, Tsvagiridzo uye kukura.

Semuenzaniso, kuburikidza nekuongorora uye hurukuro yezvinyorwa zviripo zvezvigadzirwa, dhizaini dzezvigadzirwa, uye nekugadziriswa kwezvirongwa zvechinyorwa,

Maitiro ePCB kutevedzera kunogona kuziva kukurumidza kugadzirisa, kusimudzira uye sekondari kukura kwemhando dzakasiyana-siyana dzezvigadzirwa zvemagetsi kuburikidza nekuwedzera uye chikamu chehunyanzvi hwehunyanzvi hwemafaira ehunyanzvi. Maererano neyefaira yefaira Kuda kuwana iyo dhizaini uye shandura PCB.

Izvo zvinokwanisikawo kuwedzera mabasa matsva kuchigadzirwa kana kugadziridza iyo inoshanda maficha pane izvi zvakanyorwa, asiwo mumusika wacho wakunda mukana wekutanga uye wakauya nemukana wakapetwa kune vatengi.

Kunyangwe ichishandiswa kuongorora matunhu emabhodhi uye zvigadzirwa zvechigadzirwa zvinoshandiswa mukudzokorora muzvishandiso, kana kushandiswazve sehwaro uye hwaro hwekugadzira PCB mukugadzira, PCB Schematics ine basa rakakosha.

Saka, maitiro ekudzokorora iyo PCB Schematic DiGhrainhwa zvichienderana negwaro regwaro kana chinhu chaicho, uye chii chinongedzo? Ndezvipi izvo ruzivo rwekuteerera kune?

Reverse nhanho

1. Rekodha PCB yakabatana ruzivo

Tora chidimbu chePCB, tanga rekodha modhi, parameter, uye chinzvimbo chezvikamu zvese pabepa, kunyanya kutungamira kwe diode, iyo triode, uye kutungamira kweiyo ic gap. Zvakanaka kushandisa kamera yedhijitari kutora maviri mafoto enzvimbo yezvikamu. Vazhinji PCB matunhu wedunhu vari kuwedzera zvakanyanya uye zvakanyanya kuwanda. Dzimwe dzevatengesi veDiode pamusoro hadzina kucherechedzwa zvachose.

2. Mufananidzo wakaongororwa

Bvisa zvese zvikamu uye bvisa iyo tini muHound gomba. Suka PCB nedoro uye uise mu scanner. Kana scanner scans, iwe unofanirwa kurera mapikisheni akaongororwa zvishoma kuti uwane mufananidzo wakajeka.

Wobva wanyarara jecha uye pasi pemvura nepepa remvura kusvikira iyo ravheru ruva kupenya, uvaise mu scanner, tanga photoshop, uye tarisa maviri maviri akasiyana muruvara.

Ziva kuti PCB inofanira kuiswa yakatwasuka uye yakatwasuka mune scanner, neimwe nzira iyo yakaongororwa mufananidzo haigone kushandiswa.

3. gadzirisa uye gadzirisa mufananidzo

Rongedza musiyano, kupenya uye rima reCanvas kuti uite chikamu chemafirimu emhangura zvine bukira remusikana, wobva washandura chifananidzo chechipiri kuita dema uye chena, uye tarisa kuti mitsara yakajeka. Kana zvisiri, dzokorora nhanho iyi. Kana zvakajeka, chengetedza mufananidzo kunge mutema uye chena bmm fomati mafaira epamusoro BMP uye bot BMP. Kana iwe ukawana chero matambudziko nemairafu, unogona kushandisa Photoshop kuti ugadzirise uye uvaruramise.

Shandura mafaira maviri eBmp kuProtel Fomati mafaira, uye uvanongere kuita zvikamu zviviri muProtel. Semuenzaniso, nzvimbo dzePad uye kuburikidza neyakaisa zvikamu zviviri zvakabatana, zvichiratidza kuti matanho akamboitwa aitwa nemazvo. Kana paine kutsauka, wobva wadzokorora danho rechitatu. Naizvozvo, PCB inotevedzera ibasa rinoda moyo murefu, nekuti dambudziko diki rinokanganisa hunhu uye huwandu hwekufananidza mushure mekutevedzera.

5. Dhirowa layer

Shandura iyo BMP yeiyo yepamusoro layer kune yepamusoro PCB. Teerera kutendeuka kune iyo silika layer, iyo iri iyo yero layer. Ipapo iwe unogona kuteedzera mutsara uri pamusoro wepamusoro uye isa chishandiso zvichienderana neyekudhirowa mudanho repiri. Delete iyo silika layer mushure mekudhirowa. Dzokorora kusvikira zvese zvigadzikiso zvichikweverwa.

6. Pamusoro PCB uye bot PCB yakasanganiswa mufananidzo

Ngenisa Pamusoro PCB uye bot PCB muProtel uye Sanganisa iwo mune imwe pikicha.

7. Laser inodhinda yepamusoro layer, pasi layer

Shandisa laser printer kudhinda kumusoro kweiyo yepamusoro uye pasi pefirimu rejekerere (1: 1 ratio), isa iyo firimu paPCB, uye enzanisa kana kukanganisa. Kana iri chaiyo, iwe waitwa.

8. Muedzo

Kwayedza kana iyo yemagetsi yehunyanzvi hwekuita kweiyo kopi bhodhi yakafanana nebhodhi rekutanga. Kana zvakafanana, zvaitwa chaizvo.
Kutarisisa kune ruzivo

1. Zvinonzwisisika kupatsanura nzvimbo dzinoshanda

Paunenge uchiita reserse dhizaini ye schematic dhizaini yePCB Dunhu redunhu, chikamu chakaringana chenzvimbo dzekushanda dzinogona kubatsira mainjiniya kuderedza matambudziko asina kukosha uye kuvandudza kunyatsoita basa.

Kazhinji, zvikamu zvakafanana nebasa rimwechete pane PCB Bhodhi richarongwa nenzira yakaomeswa, uye kugovera nzvimbo yacho nebasa kunogona kuve neyakaganhurana uye ichinyudza diair.

Nekudaro, kupatsanurana kwenzvimbo iyi inoshanda haisi yekukasira. Zvinoda mainjiniya kuti ave nekunzwisisa kwehukuru hwemagetsi wedunhu rakanangana nezivo.

Kutanga, tsvaga chikamu chepashure mune chimwe chinhu chinoshanda chikamu, uyezve zvinoenderana neyekurovera kwekunhuhwirira, iwe unogona kuwana zvimwe zvikamu zveiyo yakafanana inoshanda pamwe nenzira yekugadzira inoshanda chikamu.

Kuumbwa kwezvinhu zvekushanda ndiro hwaro hwechiratidzo chekutora. Mukuwedzera, mune izvi maitiro, usakanganwa kushandisa iyo computer serial nhamba pane redunhu bhodhi redunhu zvine hungwaru. Vanogona kukubatsira kupatsanura mabasa nekukurumidza.

2. Tsvaga zvirevo zvakanaka

Iyi yereferensi chikamu inogona zvakare kutaurwa kuve iyo huru chikamu PCB network guta rinoshandiswa pakutanga kweiyo schematic plock. Mushure mekutaurwa chikamu chakatsanangurwa, chirevo chinonongedzera maererano nemapipi enhasi idzi dzirevo, izvo zvinogona kuve nechokwadi chekurongeka kweiyo schematic dhizaini kusvika pamwero mukuru. Bonde.

Kune mainjiniya, kutsunga kwenhamba dzejekiti haisi nyaya yakaoma kwazvo. Mumamiriro ezvinhu akajairika, zvikamu izvo zvinotamba chinzvimbo chikuru mudunhu chinogona kusarudzwa seyenongedzo zvikamu. Ivo vanowanzove vakakura muhukuru uye vane mapini mazhinji, ayo ari nyore kudhirowa. Yakadai sekubatanidzwa kwenyika, vatinochinja, vatenderi, nezvimwe, zvese zvinogona kushandiswa sezvinhu zvakakodzera.

3. Mitsetse yakasarudzika uye dhirowa wiring zvine chikonzero

Nekuti musiyano pakati pemawaya epasi, waya dzemagetsi, uye maaini emasaini anofanirwa kuve neruzivo rwakakodzera rwemagetsi, ruzivo rwechirongwa, PCB wiring ruzivo, zvichingodaro. Kusiyanisa kwemitsetse iyi kunogona kuongororwa kubva kune zvikamu zvechikamu chekubatana, mutsara wenzombe wechipamhire uye hunhu hwechigadzirwa chemagetsi pachayo.

Mukutora kwekudhirowa, kuitira kuti udzivise kuyambuka uye kupindira kwemitsetse, huwandu hukuru hwezviratidzo zvekutanga zvinogona kushandiswa kune iyo pasi. Mitsetse yakasiyana-siyana inogona kushandisa mavara akasiyana uye akasiyana mitsara kuti ive nechokwadi chekuti ivo vakajeka uye vanozivikanwa. Zvezvinhu zvakasiyana-siyana, zviratidzo zvakakosha zvinogona kushandiswa, kana kutodhirowa matunhu eyuniti zvakasiyana, uye pakupedzisira zvisungei.

4. Tenzi iyo yekutanga chimiro uye dzidza kubva kune akafanana schematics

Kune mamwe maitiro ezvekutanga echikamu uye nhungamiro yekudhirowa, mainjiniya anofanirwa kuve nehunyanzvi, kwete kungogona kukwevera zvakananga zvimwe zvakananga uye zvakasarudzika zvikamu zvematunhu.

Kune rimwe divi, usaregeredza kuti iyo yakafanana mhando yezvigadzirwa zvemagetsi zvine mumwe akafanana mudhisheni yechiSchematic. Mainjiniya anogona kushandisa kuunganidzwa kwechiitiko uye udzidze zvizere kubva kune rimwe dunhu redunhu kuti vadzorere dhizaini yechigadzirwa chechigadzirwa chitsva.

5. Tarisa uye funga

Pashure pokunge schematic purogiramu yapera, dhizaini reverse yePCB Schematic inogona kutaurwa kuti ipedziswe mushure mekuedzwa uye kuongororwa. Iko kusaziva kukosha kwezvikamu zvinonzwisisika kune iyo PCB yekugovera paramita inoda kuongororwa uye yakagadzirirwa. Sekureva kwePCB File Diagram, Dhizaini yeSchematic iri kufananidzwa uye kuongororwa kuti ive nechokwadi chekuti schematic dhizaini inoenderana neiyo faira refair.
