Malangizo opangira ma PCB osinthasintha

Popanga PCB yokhazikika (yosindikizidwa), pali malangizo angapo omwe ayenera kutsatiridwa.Malangizowa amaonetsetsa kuti ma PCB ndi olimba, ogwira ntchito, komanso odalirika.Mu positi iyi yabulogu, tiyang'ana mwatsatanetsatane malangizo odziwika bwino a ma PCB okhwima ndi kumvetsetsa kufunikira kwawo kuti akwaniritse ntchito yabwino.Choncho, tiyeni tiyambe!

1. Konzani dongosolo lanu:

Kukonzekera bwino kwamakonzedwe a board ndikofunikira kwa ma PCB okhazikika.Kuzindikira malo a zigawo zolimba komanso zosinthika, kuyika kwa zigawo ndi njira zamanjira ndizofunikira.Masanjidwewo ayenera kukonzedwa bwino kuti achepetse kupsinjika ndi kupsinjika pazigawo zosinthika panthawi yosonkhanitsa ndikugwira ntchito.

2. Pewani kupindika ndi kupsinjika:

Chimodzi mwazofunikira pakupangira ndikupewa kupindika chakuthwa komanso kupsinjika kwambiri m'malo osinthika.Kupindika chakuthwa kumatha kuwononga zida zosinthika, zomwe zimapangitsa kuchepa kwa moyo wautumiki komanso kulephera.Okonza ayenera kuonetsetsa kuti akupendekeka pang'onopang'ono ndikugwiritsa ntchito njira zokhotakhota kuti apewe kupsinjika maganizo.

3. Chepetsani kuchuluka kwa masinthidwe osinthika kukhala osasunthika:

Kusintha kangapo pakati pa malo osinthika ndi olimba kuyenera kukhala kochepa.Kusintha kulikonse kumapanga kupsinjika kwamakina komwe kumafooketsa umphumphu wonse wa bolodi.Kuchepetsa kusinthaku kumathandizira kudalirika komanso kukhazikika.

4. Gwiritsani ntchito makulidwe oyenera a kondakitala:

Conductor m'lifupi amatenga gawo lofunikira pochepetsa kukana ndi zotsatira za kutentha.Ndikoyenera kuti tigwiritse ntchito njira zokulirapo m'malo olimba kuti tinyamule mafunde okwera komanso zocheperako m'malo osinthika kuti muchepetse kupsinjika.Kukwanira kwa kondakitala kumapangitsanso kukhulupirika kwa chizindikiro ndi kuwongolera kwa impedance.

5. Sungani makulidwe amkuwa okwanira:

Kuonetsetsa kuti magetsi akuyenda bwino komanso kutentha kwapakati, ndikofunikira kusunga makulidwe amkuwa okwanira m'malo olimba komanso osinthika.A wandiweyani mkuwa wosanjikiza umawonjezera mphamvu zamakina ndikuchepetsa kukana kwamagetsi, potero kuwongolera magwiridwe antchito onse a PCB.

6. Kuphatikiza ndi impedance yoyendetsedwa:

Kwa ntchito zothamanga kwambiri, impedance yoyendetsedwa ndiyofunikira.Opanga ayenera kuwerengera mosamala m'lifupi mwake ndi makulidwe a dielectric kuti akwaniritse zovuta zomwe zimafunikira.Kufananiza kolondola kwa impedance kumathandiza kupewa zowunikira komanso kuonetsetsa kuti magwiridwe antchito odalirika.

7. Tsatirani malangizo okhazikika:

Kukula kwamafuta ndi kutsika kumatha kukhudza kwambiri magwiridwe antchito a ma PCB okhazikika.Okonza ayenera kuyang'anitsitsa kukhazikika kwa dimensional kwa zipangizo zomwe zimagwiritsidwa ntchito.Kusankha zipangizo zokhala ndi ma coefficients ofanana a kuwonjezereka kwa kutentha kungathandize kuchepetsa chiopsezo cha kulephera chifukwa cha kupsinjika kwakukulu.

8. Onetsetsani kuti zigawozo zayikidwa bwino:

Zomwe zimayikidwa mwadongosolo ndizofunikira kwambiri pakuwongolera kutentha komanso kuchepetsa chiopsezo cha kupsinjika kwamakina.Ndi bwino kuyika zigawo zolemera kwambiri pafupi ndi malo olimba kuti tipewe kusinthasintha kwakukulu ndi kupanikizika.Kuyika mosamala kumathandizanso kuti pakhale njira yabwino komanso kukhulupirika kwa ma sign.

9. Yesani ndikutsimikizira kapangidwe kake:

Kuyesa kwakukulu ndi kutsimikizika kwa mapangidwe okhwima a PCB ndikofunikira musanayambe kupanga.Ma prototyping ndi kuyezetsa mokwanira kumathandizira kuzindikira zolakwika zilizonse zomwe zingapangidwe, zovuta zamachitidwe, kapena zovuta zopanga.Kutsimikizira kobwerezabwereza kumatsimikizira kuti mapangidwe omaliza amakwaniritsa zofunikira zonse.

10. Gwirani ntchito ndi opanga odziwa zambiri:

Kugwira ntchito ndi wopanga PCB wodziwa zambiri yemwe amagwiritsa ntchito ukadaulo wa rigid-flex ndikofunikira.Ukadaulo wawo ndi chidziwitso chawo zitha kuthandiza kukhathamiritsa mapangidwe, kutsimikizira kupanga koyenera ndikukwaniritsa miyezo yamakampani.Atha kuwongoleranso opanga posankha zida zoyenera ndi njira zochitira bwino PCB.

Pomaliza:

Ndikofunikira kutsatira malangizo awa popanga ma PCB okhazikika.Kukonzekera bwino, kulingalira za zinthu zakuthupi, mayendedwe oyendetsedwa bwino, ndi kuyezetsa koyenera ndi zinthu zofunika kwambiri pakukwaniritsa ma PCB odalirika, okhazikika.Potsatira malangizowa ndikugwira ntchito ndi wopanga wodziwa zambiri, opanga amatha kuonetsetsa kuti ntchito zawo za PCB zikuyenda bwino.
