PCB yokutevedzera bhodhi iri pcb kopi bhodhi, pcb kopi bhodhi iri pcb dombo, iri pcb dhizaini remberi mainjiniya. Chekutanga, izvo zvinoriumba zviri pcb bhodhi zvinobviswa uye zvinogadzirwa kuita BOM, uye isina bhodhi rakavhenekwa mumifananidzo uye kudzoreredzwa muPCBhodi bhodhi kudhirowa mafaera nebhodhi kutevedzera software. Tumira iyo PCB bhodhi yekudhirowa faira kuPCB fekitori kuti riite bhodhi (PCBA), wobva wawedzera izvo zvikamu (tenga zvinoenderana zvinoenderana neBOM), uye bhodhi rePCBB rakafanana chaizvo neiyo yekutanga PCB bhodhi.

Kuburikidza nePCB kuteedzera tekinoroji kunogona kupedzisa chero zvigadzirwa zvemagetsi kutevedzera, zvigadzirwa zvemagetsi kuumba.

Kuteedzera bhodhi inonziwo shanduko bhodhi, ndeyekugadzira iyo PCB bhodhi inodzosera tekinoroji tsvagiridzo. Mukureva kune yakawanda nhamba yeruzivo, iyo bhodhi yekuteedzera maitiro inopfupikiswa seinotevera:

Nhanho yekutanga, tora pcb, pekutanga pane pepa kuti unyore zvese zvinoumbwa nemuenzaniso, parameter, uye chinzvimbo, kunyanya diode, matatu pombi nzira, IC notch mirayiridzo. Zvakanakisisa kutora mifananidzo miviri yechinzvimbo cheiyo ski ine kamera yedhijitari. Ikozvino pcb redunhu bhodhi iri kuwedzera nekuwedzera kumberi pamusoro pe diode triode vamwe havateerere kungoona chete.

Nhanho 2: Bvisa zvese zvinhu uye bvisa tini kubva mumakomba ePAD. Chenesa iyo PCB nedoro uye woiisa mune scanner iyo inoongorora pamapikisheni akati kwirei kuti uwane mufananidzo unopinza. Zvadaro, polisha zvimusoro zvepamusoro nezvapasi zvishoma nepepa remavara emvura kusvikira iyo firimu yemhangura yapenya. Uzviise mukati me scanner, tanga PHOTOSHOP, uye bhuroka mativi maviri zvakasiyana muvara. Ziva kuti pcb inofanira kuiswa yakatambarara uye yakatwasuka mukati me scanner, zvikasadaro mufananidzo wakavhenekwa haugone kushandiswa.

Nhanho yechitatu, gadzirisa musiyano nemumvuri wevasheni, kuitira kuti chikamu chine mhangura firimu uye chikamu chisina mhangura firimu musiyano zvine simba, wobva wadzora subgraph kune nhema nechena, tarisa kana mitsara yacho yakajeka, kana zvisiri, dzokorora danho iri. Kana zviri pachena, chengetedza iyo pikicha seye nhema uye chena BMP fomati mafaira pamusoro.bmp uye bot.bmp. Kana paine dambudziko nemufananidzo, unogona kushandisa PHOTOSHOP kuigadzirisa nekuigadzirisa.

Nhanho yechina ndeye kushandura iwo maBMP mafaera kuita PROTEL mafaera zvichiteerana, uye nekuchinjisa maviri matanda muPROTEL. Semuenzaniso, zvinzvimbo zvePAD neVIA izvo zvakapfuura iwo matanda maviri zvinowirirana, zvichiratidza kuti matanho apfuura akaitwa nemazvo. Kana paine chero kutsauka, dzokorora danho rechitatu. Naizvozvo, pcb board kukopa ibasa rine moyo murefu, nekuti dambudziko diki rinokanganisa mhando uye nedhijitari inoenderana mushure mekuteedzera bhodhi.

Nhanho 5, chinja TOP rukoko BMP kuenda TOP.PCB, ita shuwa yekushandura SILK rara, ndiyo yeyero rukoko, wozoteedzera mutsetse pane TOP rukoko, uye woisa chishandiso zvinoenderana nemufananidzo wedanho rechipiri. Delete iyo SILK dura mushure mekupenda. Dzokorora kusvikira matanda ese atorwa.

Nhanho 6, muPROTEL, fona kumusoro. PCB uye bot. Pcb, uye uvabatanidze kuita imwe nhamba.

Nhanho 7, shandisa laser printer kudhinda iyo TOP LAYER uye BOTTOM LAYER kune yakajeka firimu (1: 1 ratio), isa iyo firimu pane iyo PCB uye enzanisa kana zvisiri izvo, kana zviri izvo, wapedza.

Kopi yebhodhi rekutanga rakagadzirwa, asi raingoitwa hafu chete. Iva nemuedzo kunyangwe, tekinoroji yemagetsi mashandiro ayo anoedza kuteedzera bhodhi yakafanana neyepakutanga bhodhi. Kana zvakaenzana saka zvanyatsoitwa.

taura pfungwa: Kana iri rakasiyana-siyana bhodhi asi zvakare rakanyatso kubwinyiswa mukati mechikamu chemukati, panguva imwechete dzokorora chetatu kusvika kuchishanu danho rekuteedzera nhanho dzemabhodhi, hongu, mifananidzo yezita iri yakasiyana, maererano huwandu hwematanho ekufunga, iyo yakajairika mbiri mapaneru ekuteedzera bhodhi iri nyore kwazvo kupfuura iyo yakawanda-maseru bhodhi, akawanda-masenduru kukopa bhodhi anokanganisa kusarongeka, Saka iyo multilayer board kopi bhodhi kuti inyatso kuve yakangwarira uye nekuchenjerera (iyo yemukati kuburikidza negomba uye kwete kuburikidza negomba iri nyore kumatambudziko).

Double mapaneru ekuteedzera nzira:

1. Skena matenga ekumusoro uye ezasi ebhodhi redunhu kuti uchengetedze maviri BMP mifananidzo.

2. Vhura quickPC 2005, tinya “Faira” uye “Vhura Base” kuvhura mufananidzo wakavhenekwa. Kurisa chidzitiro ne PAGEUP, ona padhi, isa padhi zvinoenderana nePP, ona mutsetse zvinoenderana nePT line …… Kungofanana nemwana anodhirowa, dhonza mu software uye tinya “Sevha” kuti ugadzire B2P faira.

3. Dzvanya “Faira” uye “Vhura Base Mepu” kuti uvhure iyo mepu yeparuvara yeimwe dura;

4. Dzvanya “Faira” uye “Vhura” kuvhura iyo yakambochengetwa B2P faira. Tinogona kuona kuti bhodhi richangoteedzerwa rakakwidziridzwa pamufananidzo uyu – bhodhi rimwe chete rePCB rine maburi munzvimbo imwechete, asi kubatana kwedunhu kwakasiyana. Saka isu tinodzvanya “Sarudzo” – “Layer Zvirongwa” kudzima iyo yekuratidzira yepamusoro mutsetse uye silika skrini pano, kuchisiya chete akati wandei matombo emaburi.

5. Makomba ari pauriri hwepamusoro ari panzvimbo imwechete semakomba ari muchikamu chepasi. Iye zvino tava kutsvaga mitsara mune yepasi dhizaini sezvatakaita muhudiki. Dzvanya “Sevha” zvakare – iyo B2P faira ikozvino ine data kumusoro uye kuzasi mazinga.

6. Dzvanya “Faira” “Export kune Pcb Faira”, unogona kuwana pcb faira ine maviri akaturikidzana e data, ayo anogona kuchinjiswa bhodhi kana schematic dhayagiramu kana yakatumirwa zvakananga kuPCB ndiro yefekitori yekugadzira.

Multi-layer bhodhi kutevedzera nzira:

In fact, the four board copy board is repeated copy two double panels, six is repeated copy three double panels…… Iwo akaturikidzana anotyisa nekuti isu hatisi kuona wiring mukati. Yakaomeswa multilayer bhodhi, tinoona sei iro remukati muchadenga? – akaturikidzana.

Ikozvino kune nzira dzakawanda dzekuisa, pane potion ngura, chishandiso kubvisa, asi zviri nyore kuturikidzana zvakanyanya, kurasikirwa kwedata. Zvakaitika zvinotitaurira kuti sandpaper ndiyo yakanyatsoita.

Patinopedza kuteedzera pamusoro uye wezasi rukoko rwePCB, isu tinowanzo shandisa sandpaper kukuya kubva pamusoro pevhu uye kuratidza iyo yemukati dura. Sandpaper ndiyo yakajairika sandpaper inotengeswa muchitoro chehardware, kazhinji yakaiswa paPCB, uye wobata sandpaper, zvakaenzana kukwizwa paPCB (kana bhodhi iri diki, zvakare rinogona kuiswa pasandpaper, nemumwe munwe wekubata PCB pane sandpaper kukweshera). Iyo poindi ndeye kuitsvedza kuitira kuti inyatsoenzana.

Silk skrini uye mafuta egirini zvinowanzo pukutwa, waya yemhangura uye ganda remhangura rinofanirwa kupukutwa kakawanda. Kazhinji kutaura, bhodhi reBluetooth rinogona kupukutwa mumaminetsi mashoma, ingangoita maminetsi gumi ndangariro; Ehe, nesimba rakakura, zvinotora nguva shoma; Simba ruva rinenge riine imwe nguva.

Mill ndiro ndiro zano rakajairika rinoshandiswa mukugadzirisa zvinhu parizvino, asi zvakare rakanyanya hupfumi. Tinogona kuwana chidimbu chePCB yakaraswa kwekuyedza. Muchokwadi, hazvina tekinoroji kukuya bhodhi, asi zvinongofinha. Zvinotora kumwe kuedza, uye hapana chikonzero chekushushikana nezve kukuya bhodhi nepakati uye neminwe yako.
