Pcb bhodhi Kucheka chinhu chakakosha zvemukati muPCB dhizaini. Asi nekuti inosanganisira sandpaper kukuya bhodhi (ndeye basa rinokuvadza), kutsvaga mutsara (ndewebasa rakareruka uye rinodzokorora), vagadziri vazhinji havadi kuita basa iri. Kunyangwe vagadziri vazhinji vanofunga kuti kudhira pcbc harisi basa rehunyanzvi, vechidiki vanogadzira vane zvishoma kudzidziswa vanogona kuita basa iri. Pfungwa iyi ine zvakasarudzika, asi semabasa mazhinji, kune humwe hunyanzvi mukucheka kwePBB. Kana vagadziri vakadzidza hunyanzvi uhu, vanogona kuchengetedza yakawanda nguva uye kudzikisa huwandu hwevashandi. Ngatitaurei nezve ruzivo urwu zvakadzama.

Chokutanga, pfungwa pcb bhodhi nokuveza

Pcb bhodhi yekucheka inoreva maitiro ekutora schematic uye kudhirowa bhodhi (PCB kudhirowa) kubva kune yekutanga PCB bhodhi. Chinangwa ndechekuita gare gare budiriro. Gare gare kusimudzira kunosanganisira kuiswa kwezvinhu, kuyedzwa kwakadzika, kushandurwa kwedunhu, nezvimwe.

Vaviri, pcb bhodhi yekucheka maitiro

1. Bvisa michina pabhodhi rekutanga.

2. Skena bhodhi rekutanga kuti uwane mafaira emifananidzo.

3. Gaya pasi pevhu kuti uwane yepakati.

4. Skena pakati nepakati kuti utore iyo giraidhi faira.

5. Dzokorora nhanho 2-4 kudzamara zvidimbu zvese zvagadziriswa.

6. Shandisa yakakosha software kushandura maficha emagetsi kuita emagetsi hukama mafaira -PCB dhizaini. Nesoftware chaiyo, dhizaini anogona kungoteedzera iyo graph.

7. Tarisa uye pedzisa dhizaini.

Tatu, pcb bhodhi yekucheka hunyanzvi

Pcb bhodhi yekucheka kunyanya multilayer pcb bhodhi yekucheka ibasa rinotora nguva uye rinonetsa, iro rinosanganisira yakawanda yekudzokorora basa. Vagadziri vanofanirwa kuve nemoyo murefu uye nekuchenjerera zvakakwana, zvikasadaro zviri nyore kwazvo kukanganisa. Iyo kiyi yekucheka pcb bhodhi dhizaini ndeye kushandisa yakanakira software panzvimbo yebhuku rekudzokorora basa, inova nguva yekuchengetedza uye yakarurama.

1. scanner inofanira kushandiswa mukukatanura diski

Vazhinji vagadziri vanoshandiswa kudhirowa mitsara yakanangana nePCB dhizaini masisitimu akadai sePROTEL, PADSOR kana CAD. Iyi tsika yakaipa kwazvo. Iwo akaongororwa mafaira emifananidzo haasi iwo chete hwaro hwekushandurwa kuita maPCB mafaera, asi zvakare hwaro hwekuzoongorora gare gare. Iko kushandiswa kwema scanner kunogona kudzikisa zvakanyanya kuomarara uye kusimba kwebasa. Hakusi kuwedzeredza kutaura kuti, kana iyo scanner ikashandiswa zvizere, kunyangwe vanhu vasina ruzivo rwekugadzira vanogona kupedzisa basa rekucheka pcb.

2, kuroorwa mirayiridzo kukuya ndiro

Nekumhanyisa, vamwe vagadziri vanosarudza ndiro yekudyira (ndiko kuti, kubva kumberi nekumashure nzvimbo kusvika pakati wepakati). Izvi zvakaipa chaizvo. Nekuti iyo-nzira yekukuya ndiro iri nyore kwazvo kupfeka, zvichikonzera kukuvara kune mamwe matanda, mhedzisiro inogona kufungidzirwa. Rwokunze rukoko pcb bhodhi ndiyo yakaoma uye yepakati rukoko ndiko nyorovera nokuda kwacho uye mhangura foil uye ikanyanya. Saka pakati pepakati, dambudziko rakanyanya uye kazhinji harigone kukwenenzverwa. Uye zvakare, pcb bhodhi inogadzirwa nevagadziri vakasiyana haina kufanana muhunhu, kuomarara, kusimba, zvakaoma kunyatso gaya.

3. Sarudza yakanaka kutendeuka software

Kuchinja mafaira akavezwa akavezwa kuita maFBBB ndiyo kiyi yebasa rese. Iwe une mafaira akanaka ekushandura. Vagadziri vanongo “tevedzera sutu” uye vanodhirowa mifananidzo kamwe chete kuti vapedze basa. EDA2000 inokurudzirwa pano, iri nyore kwazvo.
