PCB kuumba, yakaenzana nePCB kopi bhodhi, pcb kopi bhodhi ndiyo imwe nzira yekutaura, vatove mukufungidzira kwezvigadzirwa zvemagetsi uye bhodhi redunhu, iko kushandiswa kwekutsvagisa kwekutsvaga nekuvandudza tekinoroji zvinoreva wedunhu bhodhi rejisheni ongororo, Iwo epakutanga zvigadzirwa zvePCB faira uye zvinhu zvinyorwa (BOM), magadzirirwo magwaro akadai ehunyanzvi magwaro uye pcb faira ye screen kudhinda kugadzirwa 1: 1 kuderedzwa, uyezve shandisazve aya ehunyanzvi mafaera uye kugadzirwa kwePBB bhodhi system, zvikamu zvemoto, kubhururuka probe bvunzo , redunhu debugging, yakakwana modhi kopi yakazara yedunhu rekutanga.

Pcb yekuteedzera chete inoreva maitiro ekuburitsa uye kudzoreredza maPCB mafaira emagetsi wedunhu mabhodhi uye kuumbiridza matunhu edunhu nekushandisa mafaera. Kuteedzera bhodhi hakungosanganisi chete iyo pcb faira generic tekinoroji senge kuburitsa, pcb kuumbiridza, pcb maitiro, asi zvakare kugadzirisa pcb faira shanduko (pcb bhodhi), zvigadzirwa zvemagetsi zvemarudzi ese emagetsi zvigadzirwa pane akadhindwa wedunhu mabhodhi ruzivo kuburitsa nekumisikidza, yakavharidzirwa machipisi pabhodhi redunhu kana tekinoroji yese senge imwechete-chip decryption maitiro.

Pcb kutevedzera maitiro:

Pcb kopi bhodhi tekinoroji kuitisa maitiro mune akareruka mazwi, ndeyekutanga kuongorora kopi bhodhi redunhu mabhodhi, nyora ruzivo rwezvinhu zvacho, uye zvinhu zvinobviswa kuita zvinhu zvinyorwa (BOM) uye kuronga izvo zvinhu zvinotenga, isina chinhu ndiro yemufananidzo inoongororwa mune software kugadzirisa kumashure muPCB kopi bhodhi mufananidzo faira, uye wotumira pcb faira kune ndiro ndiro inogadzira fekitori, Mushure mekunge bhodhi raitwa, izvo zvakatengwa zvinoriumba zvichasunganidzwa kuPCB bhodhi rakagadzirwa, uyezve kuburikidza nePCB bvunzo uye debugging.

Pcb bhodhi kutevedzera nzira:

Nhanho yekutanga: tora pcb, chekutanga pane pepa kuti unyore zvese zvinoumbwa nemuenzaniso, parameter, uye chinzvimbo, kunyanya diode, matatu pombi nzira, IC notch nzira. Zvakanakisisa kutora mifananidzo miviri yechinzvimbo cheiyo ski ine kamera yedhijitari. Ikozvino bhodhi redunhu richienderera mberi zvakanyanya pamusoro pe diode triode vamwe havateerere kune vasingatomboona.

Nhanho 2: Kubvisa bhodhi: Bvisa zvese zvinhu uye bvisa tini kubva mugomba rePAD. Chenesa iyo pcb nedoro kana yekuwachisa bhodhi mvura, wozoisa mukati meiyo scanner (yakawanda-inoshanda purinta ine scanning basa). kuBMP fomati), uye chengetedza mufananidzo wakajeka. Tsvaira parutivi nesiriki sikirini, chengeta iyo faira uye woriprinta kunze kuti ushandise gare gare.

Nhanho 3: Gadzira BOM: zvinoenderana nedunhu bhodhi pikicha padanho rekutanga, nyora modhi, paramende uye chinzvimbo chezvinhu zvese pabepa, kunyanya kutungamira kwedhiode, matatu injini chubhu uye IC notch, uye pakupedzisira ita BOM.

Nhanho 4: Kukuya ndiro: ChiPolish iyo inki yeTOP LAYER uye BOTTOM LAYER nemapepa mapepa kusvikira iyo mhangura firimu yopenya, wozoiisa mu scanner uye ramba uchiongorora mifananidzo yakanaka neyakaipa (ona kuti Iyo PCB inofanirwa kuiswa yakatwasuka uye yakatwasuka mu scanner, zvikasadaro iwo mufananidzo wakavhenekwa unodzedzereka, uye zvichanetsa kugadzirisa mufananidzo gare gare) uye chengeta iyo faira.

Nhanho 5: Hora: Mhanya PHOTOSHO kuvhura iyo yakavhenekwa pikicha, gadzirisa musiyano uye mumvuri wevasheni, kuitira kuti chikamu chine mhangura firimu uye chikamu chisina mhangura firimu musiyano zvine simba, tarisa kana mitsara yakajeka, kana zvisiri, dzokorora izvi nhanho. Kana zvikajeka, mufananidzo wacho unochengetwa seruvara rweBMP fomati mafaira pamusoro.bmp uye bot.bmp. Kana paine dambudziko nemufananidzo, unogona kugadziridzwa nekugadziriswa nePhotosHOP.

Nhanho 6: Mufananidzo calibration: Tanga iyo PCB yekuteedzera software QuickPcb2005 uye tumira iwo akaongororwa maPCB mapikicha mune iyo faira menyu. Semuenzaniso, zvinzvimbo zvePAD neVIA kuburikidza nematanho maviri zvinowirirana, zvichiratidza kuti matanho apfuura akaitwa nemazvo. Kana paine chero kutsauka, dzokorora nhanho yechishanu.

Nhanho 7: kurongedza kugadzirwa uye yekudhirowa mutsetse: tumira iyo BMP pikicha yeiyo TOP rukoko mu QuickPcb2005 software, zvichiteerana mune inoenderana dura, uye wozoisa mudziyo, zvichiteerana zvichiratidza iyo TOP rukoko uye BOTTOM dura remutsara.

Nhanho 8: Export pcb faira: Mushure mekuwanda kwekudhirowa kwaitwa mu QuickPC 2005 software, tumira kunze iyo faira uye chengeta se. Pcb fomati.

Nhanho 9: Faira mushure mekugadzirisa uye kugadzirisa: Tumira kunze kwenyika. Pcb fomati faira mune EDA software yekugadzirisa. Inokurudzirwa kushandisa Alitum Desiger 19 kugadzirisa iyo faira uye DRC cheki, uye kuburitsa iyo GENERATED pcb faira.
