Matunhu matatu ekuchengetedza simba resimba mukatiPCB Kugadzira
Muchigadzirwa chazvino chemagetsi emagetsi, kuvimbika kwemasimba chinhu chakakosha chikamu chePCB Dhizaini. Kuve nechokwadi chekushanda kwakasimba uye kuita kwemidziyo yemagetsi, isu tinofanirwa kufunga uye kugadzira zvine simba kubva kune simba remagetsi kune anogamuchira.
Kuburikidza nekunyatsogadzira uye kururamisa masimba module, yemukati layer ndege, uye magetsi ekupa machipisi anogona kunyatsozadzisa kuvimbika kwesimba. Chinyorwa ichi chinokwevera mune izvi zvinhu zvitatu zvakakosha kupa nhungamiro inoshanda uye mazano ezvinyorwa zvePCB.
I. Simba Module Rudzi rweWiring
Magetsi magetsi isimba resimba remidziyo yega yega yemagetsi, kuita kwayo uye marongero akananga anokanganisa kugadzikana uye kushanda kwehurongwa hwese. Iyo yakarongedzwa chimiro uye kufambisa haigone kungoderedza ruzha kupindira asi zvakare kuve nechokwadi chekuyerera chazvino, nekuvandudza kuita kwakazara.
2.power module dhizaini
1.Source Kugadzirisa:
Iyo module yemagetsi inofanirwa kuve yakabhadharwa kubviswa sezvo ichishanda seyekutanga sosi. Kuti uderedze sumo yeruzha, nharaunda yakatenderedza iyo module inofanirwa kuchengetwa seyakachena sezvinobvira kudzivirira kuderera kune vamweyakakwira-frequencykana mavara-anotarisisa zvikamu.
2.Close kune Simba Supply Chip:
Iyo magetsi module inofanira kuiswa padyo neye simba-rinopihwa chip sezvinobvira. Izvi zvinogona kuderedza kurasikirwa mukuita kwazvino kutumira uye kuderedza izvo zvinodiwa munzvimbo yemukati yemukati.
3.Heat Kuparadza Kukurukurirana:
Iyo module yemagetsi inogona kuburitsa kupisa panguva yekushanda, saka inofanira kuve yakavimbiswa kuti hapana zvipingaidzo pamusoro payo zvekupisa kwekupisa. Kana zvichidikanwa, heatsinks kana mafani anogona kuwedzerwa kutonhora.
4.Kunodes loops:
Paunenge uchifambisa, dzivisa kuumba zvishwe zvazvino kuti uderedze mukana wekukanganiswa kweElectromagnet.
Ii. Yemukati layer ndege dhizaini kuronga
A. Rayer Stack Dhizaini
In PCB EMC Dhizaini.
a. Kuve nechokwadi chekukaswa midziyo yeiyo ndege yemagetsi uye kuyamwisa ruzha ruzha, chinhambwe pakati pemagetsi uye ndege dzinofanirwa kupfuura 10mil, kazhinji dzakakurudzirwa kuve isingasviki 5mil.
b. Kana imwe chete isina simba ndege isingagone kuitwa, nzvimbo yekuvhara inogona kushandiswa kuisa ndege yemagetsi. Iyo yakanyanya kusimba simba uye pasi pezvirongwa zvinoumba ndege yePlan ine mashoma AC kukundikana uye yakanaka kwazvo-frequency maitiro.
c. Dzivisa padyo nepamadzo maviri emagetsi, kunyanya nemisiyano yakakura yekuvhiringidza, kudzivirira ruzha. Kana zvisingadzivirirwe, wedzera kupatsanurwa pakati peiyo mbiri yezvinhu zviyero zvakanyanya sezvinobvira.
d. Zvirongwa zvezvirongwa, kunyanya masimba masimba ekureva, anofanirwa kuchengetedza akaderera asina kujairika maitiro uye anogona kuongororwa kuburikidza neakadzika ecacitors uye denderedzwa kugadzirisa.
B.Multiple Poll Segmentation
a. Zvekare zvidiki-mhando masimba masimba, senge mushonga wekushanda mubatanidzwa weiyo AC, ndarira inofanirwa kuve neyecherechedzo ndege yePower,
b. Iko kusarudzwa kwekukwirira kwakaringana kunofanirwa kuve kwakakodzera. Kana voltage voltage yakakura kupfuura 12v, upamhi hunogona kuve 20-30mil; Zvikasadaro, sarudza 12-20mil. Chinyorwa chechikamu chakapamhama uye digital masosi anofanirwa kuwedzerwa kuti adzivise simba remudhiji kubva mukukanganiswa neAnalog Simba.
c. Simba remagetsi netiwe dzinofanira kuzadzikiswa pane iyo yekunongedza layer, uye kureba magetsi magetsi anofanirwa kuve neFilter capacitors yakawedzerwa.
d. Iyo yakasarudzika masimba ndege inofanirwa kuchengetwa nguva dzose kuti udzivise zvisingaiti zvigadzikiso zvichikonzera kudzikisira uye kuwedzera simba risina simba. Yakareba uye yakatetepa mitsetse uye mapoka akaumbwa-akaumbwa hazvibvumirwe.
C.Plane kufefetera
a. Iyo ndege yemagetsi inofanirwa kusungirirwa padhuze nendege yepasi.
b. Zvechipisi nemachipisi ekushanda anopfuura 500mhz, kunyanya kuvimba nePlane capacitor yekucheka uye shandisa musanganiswa weCacaititor yekucheka. Iyo yekufemera mhedzisiro inoda kusimbiswa nekupararira kwesimba.
c. Isa madzinza ekusarudza mapepa epacitors pane iyo yekudzora ndege, yakadai seyakakurumidza capacitor inotungamira uye kuwedzera capacitor vias, kuve nechokwadi chekuti simba ivhu rakadzika kupfuura rakarongeka pane kutarisirwa.
III. Power Chip Layout Wiring
Iyo chip yesimba ndiyo musimboti wemidziyo yemagetsi, uye ichine kuvimbika kwaro kwakakosha kwekuvandudza kushanda kwemishini uye kugadzikana. Simba Kuvimbika Kudzora kwesimba Zvipisi kunyanya kunosanganisira kudzora kubata kwechip simba pini uye kurongeka kwakarongeka uye kurongeka kwekurongedza capacitors. Izvi zvinotevera zvichadzokorora kufunga uye zano rinoshanda pamusoro pezvinhu izvi.
A.chipipi Power Pin Routing
Kufamba kweChip simba Pins chikamu chakakosha chekutendeseka kwesimba. Kuti upe nzvimbo yakagadzikana yazvino, inokurudzirwa kudzora kufambisa kwemapipi emasimba, kazhinji kune yakaenzana sey chip pini. Kazhinji, theMinimum Yakakurahaifanire kunge iri pasi pe 8mil, asi kuti uwane mhedzisiro, edza kuzadzisa chiupamhi hwegumi. Nekuwedzera iyo yakafara kwazvo, kusakwana kunogona kuderedzwa, nekudaro kudzikisira ruzha rwemagetsi uye kuona zvakakwana zvazvino kuwanikwa kune chip.
B.loyout uye kufambisa kwekushongedza capacitors
Decoupling capacitors inotamba yakakosha basa mukuvimbika kwesimba rekutonga kwemappi emasimba. Zvichienderana neCapacitor hunhu uye zvido zvekushandisa, decoupling capacitors inowanzo kupatsanurwa kuva yakakura uye diki capacitors.
a. Hombe capacitors: hombe capacitors dzinowanzo kugoverwa zvakatenderedza chip. Nekuda kweiyo yavo yepazasi reident
b. Diki Capacitors: Diki Capacitors vane yakakwira resonant frequent Vakuviga kure kure kunogona kusanyatsoita kuti vabudise ruzha-nguva refu-frequency, kurasikirwa nemhedzisiro yekushongedza. Ruramisa ruramisiro inovimbisa kuti kushanda kwezvidimbu zvidiki mukuvhara ruzhinji-frequency ruzha rwunoshandiswa zvizere.
C.Vaura nzira yekuenzanisa decoupling capacitors
Kuenderera mberi nekuvandudza simba rekuvimbika, dzakawanda decoupling capacitors dzinowanzobatanidzwa mukufananidza. Chinangwa chikuru cheiyi tsika ndechekuderedza iyo yakaenzana seriestance
Paunenge uchifananidza akawanda decoupling capacitors, kutarisa kunofanirwa kubhadharwa kune kuiswa kweVias kune capacitors. Tsika yakajairika ndeyekuisa iyo inosimbisa simba uye pasi. Chinangwa chikuru cheizvi ndechekuderedza kutsauka mukuwirirana pakati pekushongedza capacitors. Ita shuwa kuti kureverera kuri kushoma kudiki pane iyo esl yeimwe capacitor, kuitira kuti esl esl isingarevi mushure mekuenderana yakawanda decoupling capacitors ndeye 1 / n. Nekuderedza kutsauka kunyengera, kushandisirwa zvakanaka kunogona kuvandudzwa zvinobudirira, kuvimba nekuvandudzwa kwakavandudzwa.
Chimirouye kufambisa kwesimba module, yemukati layer ndege yekugadzira ndege kuronga, uye kururamisa kubata kwesimba chip Kuburikidza nehurongwa hwakakodzera uye kufambisa, isu tinogona kuve nechokwadi chekugadzikana uye kushanda kwemasimba emasimba, kuderedza ruzha kupindira, uye kugadzirisa zvese kuita. Layer Stack Dhizaini uye akawanda Simba Chikamu chekutsiva chinowedzera maitiro ehurongwa hwemagetsi, kuderedza kurira kwesimba. Kubata Kwakakodzera kwePower Simba Nesimba uye kurongedza uye kurongedza capcitors kwakakosha kune simba rekuvimbika kutonga, kunoita kuti isimbe yekupa ruzha uye inosimbisa basa rekushandisa, kuishandira mudziyo kushanda uye kugadzikana.
Mukushanda kunoshanda, zvinhu zvakasiyana-siyana zvakadai sekukura kwazvino, kuyaruka, nhamba yeVias, mhedzisiro, nezvimwe, inoda kusanzwisisana nekuita zvine musoro uye kusarudzika. Tevedza dhizaini yekugadzira uye zvakanakisa maitiro kuti uve nechokwadi chekudzora uye kurerutswa kwekuvimbika kwesimba. Nenzira iyi chete isu tinogona kupa simba rakasimba uye dzisingabatike midziyo yemagetsi, sangana nekuwedzera kwekuita kunodiwa, uye kutyaira kukura uye kufambira mberi kwehunyanzvi hwemagetsi.
