PCB Design

PCB kupanga

Mapulogalamu

1. Mapulogalamu omwe amagwiritsidwa ntchito kwambiri ku China ndi Protel, Protel 99se, Protel DXP, Altium, amachokera ku kampani yomweyi ndipo amasinthidwa nthawi zonse;mtundu waposachedwa ndi Altium Designer 15 womwe ndi wosavuta, kapangidwe kake kamakhala kosavuta, koma osati kwabwino kwambiri kwa ma PCB ovuta.

2. Cadence SPB.Mtundu wamakono ndi Cadence SPB 16.5;kamangidwe ka ORCAD ndi muyezo wapadziko lonse lapansi;Mapangidwe a PCB ndi kayeseleledwe kabwino kwambiri.Ndizovuta kugwiritsa ntchito kuposa Protel.Zofunikira zazikulu zili m'makonzedwe ovuta.;Koma pali malamulo a mapangidwe, kotero kuti mapangidwe ake ndi abwino kwambiri, ndipo ndi amphamvu kwambiri kuposa Protel.

3. BORDSTATIONG ya Mentor ndi EE, BOARDSTATION imangogwira ntchito ku UNIX system, yosapangidwira PC, kotero anthu ochepa amagwiritsa ntchito;mtundu waposachedwa wa Mentor EE ndi Mentor EE 7.9, uli mulingo womwewo ndi Cadence SPB, mphamvu zake ndikukoka waya ndi waya wowuluka.Amatchedwa flying wire king.

4. Mphungu.Ichi ndi ambiri ambiri ntchito PCB kapangidwe mapulogalamu mu Europe.Mapulogalamu opangira PCB omwe atchulidwa pamwambapa amagwiritsidwa ntchito kwambiri.Cadence SPB ndi Mentor EE ndi mafumu oyenerera.Ngati ndi PCB yoyambira kupanga, ndikuganiza kuti Cadence SPB ndiyabwinoko, imatha kukhala ndi chizolowezi chopanga mapangidwe abwino, ndikuwonetsetsa kuti mapangidwe ake ali abwino.

Maluso okhudzana

Malangizo okhazikitsa

Kapangidwe kake kamayenera kukhazikitsidwa pazigawo zosiyanasiyana m'magawo osiyanasiyana.Mugawo la masanjidwe, mfundo zazikuluzikulu za gridi zitha kugwiritsidwa ntchito popanga zida;

Pazida zazikulu monga ma IC ndi zolumikizira zosayika, mutha kusankha kulondola kwa gridi ya 50 mpaka 100 mils pakuyika.Pazida zing'onozing'ono monga resistors, capacitors, ndi inductors, mutha kugwiritsa ntchito 25 mils pakuyika.Kulondola kwa mfundo zazikuluzikulu za gridi kumapangitsa kuti chipangizocho chikhale chokhazikika komanso chokongola.

Makhalidwe a PCB:

1. Nthawi zonse, zigawo zonse ziyenera kuikidwa pamtunda womwewo wa bolodi la dera.Pokhapokha pamene zigawo za pamwamba zimakhala zowuma kwambiri, zida zina zotsika kwambiri komanso zotentha kwambiri, monga chip resistors, chip capacitors, phala Chip ICs zimayikidwa pansi.

2. Pazifukwa zowonetsetsa kuti magetsi akugwira ntchito, zigawozo ziyenera kuikidwa pa gridi ndikukonzekera mofanana kapena perpendicular kwa wina ndi mzake kuti zikhale zabwino komanso zokongola.Muzochitika zachilendo, zigawozo siziloledwa kuti zigwirizane;zigawozo ziyenera kukonzedwa bwino, ndipo zigawozo ziyenera kukhala pa dongosolo lonse Kugawa kwa Uniform ndi kachulukidwe yunifolomu.

3. Kutalikirana kochepa pakati pa mapepala oyandikana nawo a zigawo zosiyanasiyana pa bolodi lozungulira kuyenera kukhala pamwamba pa 1MM.

4. Nthawi zambiri amakhala osachepera 2MM kutali ndi m'mphepete mwa bolodi.The mawonekedwe abwino a bolodi dera ndi amakona anayi, ndi kutalika kwa m'lifupi chiŵerengero cha 3: 2 kapena 4: 3. Pamene bolodi kukula ndi wamkulu kuposa 200MM ndi 150MM, angakwanitse wa bolodi dera ayenera kuonedwa Mechanical mphamvu.

Maluso kamangidwe

Pamapangidwe a PCB, gawo la board board liyenera kuwunikidwa, kapangidwe kake kayenera kutengera ntchitoyo, ndipo masanjidwe a zigawo zonse zadera ayenera kukwaniritsa mfundo izi:

1. Konzani malo a gawo lililonse logwira ntchito molingana ndi kayendedwe ka dera, pangani masanjidwewo kuti azitha kuyenda bwino, ndikusunga chizindikirocho momwe mungathere.

2. Ndi zigawo zikuluzikulu za gawo lililonse zinchito monga pakati, masanjidwe momuzungulira.Zigawozo ziyenera kukhala zofanana, zogwirizana komanso zokonzedwa bwino pa PCB kuti kuchepetsa ndi kufupikitsa kutsogolera ndi kugwirizana pakati pa zigawozo.

3. Kwa mabwalo omwe amagwira ntchito pamtunda wapamwamba, magawo ogawa pakati pa zigawo ayenera kuganiziridwa.Dera lonse liyenera kukonza zigawozo mofanana momwe zingathere, zomwe sizili zokongola zokha, komanso zosavuta kuziyika ndi zogulitsa, komanso zosavuta kupanga zambiri.

Masitepe apangidwe

Kamangidwe kamangidwe

Mu PCB, zigawo zapadera zimatanthawuza zigawo zikuluzikulu zomwe zili mu gawo lapamwamba kwambiri, zigawo zazikuluzikulu zomwe zili muderali, zigawo zomwe zimasokonekera mosavuta, zigawo zomwe zimakhala ndi magetsi apamwamba, zigawo zomwe zimakhala ndi kutentha kwakukulu, ndi zina zogonana ndi amuna kapena akazi okhaokha. Malo a zigawo zapaderazi ayenera kufufuzidwa mosamala, ndipo masanjidwewo amayenera kukwaniritsa zofunikira za ntchito ya dera ndi zofunikira zopanga.Kuyika kolakwika kwa iwo kungayambitse mavuto okhudzana ndi dera komanso zovuta zaumphumphu, zomwe zingayambitse kulephera kwa mapangidwe a PCB.

Mukayika zigawo zapadera pamapangidwe, choyamba ganizirani kukula kwa PCB.Pamene kukula kwa PCB kuli kwakukulu, mizere yosindikizidwa ndi yaitali, kusokoneza kumawonjezeka, mphamvu yotsutsa kuyanika imachepa, ndipo mtengo umawonjezeka;ngati ndi yaying'ono kwambiri, kutentha kwa kutentha sikuli bwino, ndipo mizere yoyandikana nayo imasokoneza mosavuta.Pambuyo pozindikira kukula kwa PCB, dziwani malo a pendulum a gawo lapadera.Pomaliza, malinga ndi gawo logwira ntchito, zigawo zonse za dera zimayikidwa.Malo omwe ali ndi zigawo zapadera ayenera kutsatira mfundo zotsatirazi panthawi ya masanjidwe:

1. Kufupikitsa kugwirizana pakati pa zigawo zapamwamba kwambiri momwe mungathere, yesetsani kuchepetsa magawo awo ogawa ndi kusokoneza ma electromagnetic.Zomwe zimakhudzidwa sizingakhale zoyandikana kwambiri, ndipo zolowetsa ndi zotulutsa ziyenera kukhala kutali momwe zingathere.

2 Zigawo zina kapena mawaya amatha kukhala ndi kusiyana kwakukulu, ndipo mtunda wawo uyenera kuwonjezeka kuti tipewe maulendo afupipafupi omwe amayamba chifukwa cha kutulutsa.Zigawo zamphamvu kwambiri ziyenera kusungidwa kuti zisafike.

3. Zigawo zolemera kuposa 15G zimatha kukhazikitsidwa ndi mabulaketi ndikumangirira.Zigawo zolemetsa ndi zotentha siziyenera kuikidwa pa bolodi la dera koma ziyenera kuikidwa pansi pa chassis chachikulu, ndipo kutaya kutentha kuyenera kuganiziridwa.Zigawo zotentha ziyenera kusungidwa kutali ndi zigawo zotentha.

4. Kukonzekera kwa zigawo zosinthika monga potentiometer, ma coil osinthika osinthika, ma capacitor osinthika, ma micro switch, etc. ayenera kuganizira zofunikira zamagulu a bolodi lonse.Zosintha zina zomwe zimagwiritsidwa ntchito pafupipafupi ziyenera kukhala Ikani pomwe mungathe kuzifikira mosavuta ndi manja anu.Mapangidwe a zigawozo ndi oyenerera, wandiweyani komanso wandiweyani, osati pamwamba-wolemera.

Chimodzi mwa zopambana za mankhwala ndi kumvetsera khalidwe lamkati.Koma m'pofunika kuganizira kukongola konsekonse, onse ndi matabwa angwiro, kuti akhale mankhwala opambana.

Kutsatizana

1. Ikani zigawo zomwe zimagwirizana kwambiri ndi kapangidwe kake, monga zitsulo zamagetsi, magetsi owonetserako, zosintha, zolumikizira, ndi zina zotero.

2. Ikani zigawo zapadera, monga zigawo zazikulu, zolemetsa, zigawo zotentha, zosinthira, ICs, ndi zina zotero.

3. Ikani zigawo zing'onozing'ono.

Kufufuza kamangidwe

1. Kaya kukula kwa bolodi la dera ndi zojambulazo zikugwirizana ndi miyeso yokonzekera.

2. Kaya masanjidwe a zigawozo ali olinganizidwa bwino, okonzedwa mwaukhondo, komanso ngati zonse zayalidwa.

3. Kodi pali mikangano pamagulu onse?Monga ngati zigawo, chimango chakunja, ndi mlingo wofuna kusindikiza kwachinsinsi ndizomveka.

3. Kaya zigawo zomwe zimagwiritsidwa ntchito nthawi zambiri ndizosavuta kugwiritsa ntchito.Monga masiwichi, mapulagi-ma board omwe amalowetsedwa mu zida, zida zomwe ziyenera kusinthidwa pafupipafupi, ndi zina.

4. Kodi mtunda pakati pa zigawo zotentha ndi zotentha ndizoyenera?

5. Kaya kutentha kwa kutentha kuli bwino.

6. Kaya vuto la kusokoneza mzere liyenera kuganiziridwa.

Nkhani ndi zithunzi zochokera pa intaneti, ngati kuphwanya kulikonse pls lemberani kuti tifufute.
