Pali zinthu zitatu kuti muteteze umphumphu wamphamvu mwaPCB Kupanga

M'mapangidwe amakono pamagetsi, kukhulupirika kwamphamvu ndi gawo lofunikira kwambiri la kapangidwe ka PCB. Kuonetsetsa ntchito yokhazikika komanso magwiridwe antchito amagetsi, tiyenera kuganizira komanso kupanga bwino kuchokera ku wolandirayo kwa wolandirayo kwa wolandirayo.

Mwa kupanga ma module mosamala ndi ma module amphamvu, ndege zamkati, ndi tchipisi champhamvu, titha kukwaniritsa bwino umphumphu. Nkhaniyi idulira m'magulu atatu ofunikawa kuti apereke malangizo othandiza komanso njira zopangira a PCB.

I. Mphamvu module yamphamvu

Magetsi ndi gwero la zida zamagetsi zilizonse, magwiridwe ake ndi malowa amakhudza mwachindunji kukhazikika ndi mphamvu yonse. Maonekedwe oyenera komanso oyenda sangangochepetsa phokoso laphokoso koma kutsimikizira kuti kuyenda bwino kwamakono, potero kumapititsa patsogolo mayendedwe apano.

2.Pouter module

1.Source kukonza:

Magetsi akuyenera kuyang'aniridwa mwapadera popeza amayamba kufalikira. Kuchepetsa phokoso mawu oyambira, malo omwe ali pafupi ndi magetsi ayenera kusungidwa moyera momwe mungathere kuti mupewe kuyanjana ndi enapafupipafupikapena zigawo zokopa.

2.close ku chip yamphamvu:

Mafuta amphamvu ayenera kuyikidwa pafupi ndi chip chomwe chimaperekedwa ndi mphamvu momwe mungathere. Izi zimatha kuchepetsa kutayika mu njira yofalitsira yomwe yatumizidwa ndikuchepetsa malo a ndege yamkati.

3.

Magetsi omwe amatha kupanga kutentha pakugwira ntchito, motero ziyenera kutsimikiziridwa kuti kulibe zofota pamwamba pake chifukwa chosintha kutentha. Ngati ndi kotheka, kutentha kapena mafani amatha kuwonjezeredwa kuti muzizire.

4.

Mukamayenda, pewani kupanga malupu omwe akupezeka kuti muchepetse kuthekera kwa zosokoneza zamagetsi.

Ii. Kukonzekera kwamkati kwa ndege

A.

In Kapangidwe ka PCB EMC, kapangidwe kake kathunthu ndi chinthu chofunikira kwambiri kulinganiza njira yogawa ndi kufalitsa mphamvu.

a. Kuonetsetsa kuti palipo lonse lamphamvu ndi kuyamwa kwa phokoso lamphamvu, mtunda pakati pa mphamvu ndi ndege zapansi sikuyenera kupitirira 10mil, omwe amalimbikitsidwa kukhala ochepera 5mil.

b. Ngati ndege imodzi siyingagwiritsidwe ntchito, malo osanjikiza pamtunda angagwiritsidwe ntchito kuyika ndege. Mphamvu yoyandikana kwambiri ndi ndege yoyaka pansi imapanga capacitor ya ndege yokhala ndi ziphuphu zosachepera mac komanso mawonekedwe apamwamba kwambiri.

c. Pewani kuyang'anitsitsa zigawo ziwiri zamagetsi, makamaka ndi magetsi akulu akulu, kuteteza phokoso. Ngati simukupepuka, onjezani kutalika pakati pa zigawo ziwiri zamphamvu momwe mungathere.

d. Ndege zam'madzi, makamaka ndege zomwe zimayambitsa mphamvu, ziyenera kukhala ndi mawonekedwe ocheperako ndipo imatha kukhazikitsidwa kudzera mu ma cartactors ndi kusintha kwa osanjikiza.

B.Multiple gawo

a. Kwa magwero amphamvu kwambiri, monga magetsi ogwirira ntchito pachip, pomwe mkuwa uyenera kuyikika pa siginecha kuti uzikadzoza wamphamvu, koma pewani kuyika mkuwa wamphamvu pamkuwa kuti muchepetse ma radiation.

b. Kusankhidwa kwa gawoli kuyenera kukhala koyenera. Mphamvu yamphamvu ikakhala yayikulu kuposa 12V, m'lifupi likhoza kukhala 20-30mil; Kupanda kutero, sankhani 12-20mil. Gawo lalifupi pakati pa Analog ndi magetsi a digito akuyenera kuchuluka kuti mupewe mphamvu zama digito posokoneza mphamvu ya Analog.

c. Maukonde osavuta a Mphamvu ayenera kumalizidwa pamtunda, ndipo maulendo ataliatali amayenera kukhala ndi ma caremactors owonjezedwa.

d. Ndege yolumikizidwa iyenera kusungidwa kuti isapewe mawonekedwe osasinthika ndikuwonjezera mphamvu. Zigawo zazitali komanso zopapatiza zowoneka bwino za Dumbbell siziloledwa.

C.Plane zosema

a. Ndege yamagetsi iyenera kuyamikiridwa kwambiri ndi ndege.

b. Kwa tchipisi okhala ndi maulendo ogwiritsira ntchito kwambiri 500mhz, makamaka amadalira kusefa kwapamwamba ndikugwiritsa ntchito kusefa kwa capacilator. Zotsatira zosefera zimayenera kutsimikiziridwa ndi kuyerekezera umphumphu wamphamvu.

c. Khazikitsani Inctitors Othandizira pa ndege yowongolera, monga kukula kwapakatikati kuwongolera ndi kuwunika kwapamwamba, kuonetsetsa kuti kutsika kwa nthaka ndikotsika kuposa zomwe mukufuna.

Iii. Mphamvu yakufa

Chip yamphamvu ndi maziko a zida zamagetsi, ndikuwonetsetsa kuti ndi mtima wake wamagetsi ndiofunikira kuti athe kusintha magwiridwe antchito ndi kukhazikika. Kuwongolera umphumphu wa Mphamvu kuti chips chips chimaphatikizapo chipwirikiti chogwiritsira ntchito zipika za chip ndi mawonekedwe olondola komanso owombera a mavacoroling. Izi zidzafotokoza mwatsatanetsatane malingaliro ndi upangiri wothandiza pankhaniyi.

A.chip Power Punt

Mapaini a Chip Power ndi gawo lofunikira kwambiri la kuwongolera umphumphu wa umphumphu. Kuti mupereke zokhazikika pamakono, tikulimbikitsidwa kuti mukulungidwe gawo la zikhomo zamphamvu, nthawi zambiri kumaliseche ngati zitsime. Nthawi zambiri,Mbali yocheperakosayenera kukhala ochepera 8mil, koma chifukwa cha zotsatira zabwinoko, yesani kukwaniritsa m'lifupi 10mil. Mwakuwonjezera m'lifupi mwake, kusokonekera kumatha kuchepetsedwa, motero kuchepetsa phokoso lamphamvu ndikuonetsetsa zokwanira ku chichipi.

B.laut ndi njira yolumikizira icactor

Makina owonda amagwira ntchito yofunika kwambiri yolamulira kukhulupirika kwa mapiko amphamvu. Kutengera ndi mawonekedwe ndi zofunikira pa ntchito, ma carpolling carpocling nthawi zambiri amagawika m'mapamwamba ndi ang'onoang'ono.

a. Akuluakulu akuluakulu: Makanema akuluakulu nthawi zambiri amagawidwa mozungulira kuzungulira chip. Chifukwa cha radius yapansi yotsika ndi radius yopanda kanthu, amatha kusefa bwino kwambiri phokoso locheperako ndikupereka magetsi okhazikika.

b. Makina ang'onoang'ono: Makina ang'onoang'ono amakhala ndi pafupipafupi ndipo ang'onoang'ono osenda, chifukwa amayenera kuyikidwa pafupi ndi zikhomo za chip. Kuwazungulira kutali kwambiri sikungaseweretse phokoso laphokoso kwambiri, kutaya thupi. Masanja olondola amatsimikizira kuti luso la akavactors ang'onoang'ono pakusepera phokoso lambiri lomwe limagwiritsidwa ntchito mokwanira.

C.WIRRIND Njira yofananira

Kuti apitirize kupititsa patsogolo umphumphu wamagetsi, ma carpocitors ambiri amalumikizidwa nthawi zambiri. Cholinga chachikulu cha kuyesereraku ndikuchepetsa mndandanda wofanana (esl) wa caysors payekhapayekha kulumikizana.

Mukamafananitsa ma icactors angapo, chidwi chiyenera kulipiridwa ku ma caias a capoctors. Njira yodziwika bwino ndiyo kuthetsa zipatso zamphamvu ndi nthaka. Cholinga chachikulu cha izi ndikuchepetsa chizolowezi chosinthika pakati pa ma carports. Onetsetsani kuti kusinthika kwamphamvu kumakhala kocheperako kuposa esl ya spicator imodzi, kotero kuti esl iplence yofanana ndi ma carpouple ambiri atatsanzikana ndi 1 / n. Mwa kuchepetsa kusanjana, kufooketsa bwino kumatha kukulitsidwa bwino, kuonetsetsa kukhazikika kwamphamvu.

MapuNdipo ma module a mphamvu, masitepe amkati pa ndege ya ndege, ndikugwirizanitsa koyenera kwa makondo a Hirp ndi kuwonda ndikofunikira pakupanga kwa chipangizo chamagetsi. Kudzera mu mapangidwe oyenera komanso kukhazikika, titha kuwonetsetsa kuti ma module amphamvu, amachepetsa phokoso laphokoso, ndikusintha magwiridwe antchito. Kupanga kwapadera ndi magawo angapo amphamvu kumalimbikitsanso mawonekedwe a ndege a ndege, kuchepetsa zosokoneza zamphamvu zamphamvu. Kugwira ntchito moyenera kwa chipongwe champhamvu komanso chowonda komanso chovuta kuwongolera kuwongolera umphumphu wamphamvu, kuwonetsetsa kuti mukuyika kwamphamvu komanso kufooketsa phokoso.

Pogwira ntchito, zosiyanasiyana monga kukula kosiyanasiyana, kutalika kwake, kuchuluka kwa mawu, zotsatira za kusintha, zina zophatikizira, etc. Tsatirani kapangidwe ka kapangidwe kake ndi machitidwe abwino kuonetsetsa kuti kuwongolera ndi kukhathamiritsa kukhulupirika kwamphamvu. Pokhapokha ngati tingathe kupereka magetsi okhazikika komanso okwanira zida zamagetsi, kudzakwaniritsa zofuna za magetsi, ndikuyendetsa chitukuko chaukadaulo zamagetsi.
