Iinkalo ezintathu zokukhusela ukunyaniseka kwamandla kwiUyilo lwe-PCB
Kwiyilo yale yanamhlanje, ingqibelelo yamandla yinxalenye engenakuphikiswa yoyilo lwe-PCB. Ukuqinisekisa ukusebenza ngokuzinzileyo kunye nokusebenza kwezixhobo ze-elektroniki, kufuneka siqwalasele kwaye siyile kwaye siyilo ngokupheleleyo kumthombo wamandla kumthombo wamandla.
Ngokuyila ngononophelo kunye nokwandisa iimodyuli zombane, iindiza ze-Inriner Arzer, kunye neChips Ships Sinokuyifumana ngokwenene ingqibelelo. Eli nqaku liza kuthoba kwezi zinto zintathu ziphambili ukubonelela ngesikhokelo kunye nezicwangciso-nkqubo zoyilo lwe-PCB.
I. Imodyuli yemodyuli yamandla
Imodyuli yoMbane nguMthombo wamandla kuzo zonke izixhobo ze-elektroniki, ukusebenza kunye nokubekwa kwekhompyutheni kuchaphazela ngqo uzinzo kunye nokusebenza kakuhle kwale nkqubo iphela. Ubume obufanelekileyo kwaye i-rowseng ayinakukwazi ukunciphisa ukuphazamiseka kwengxolo kodwa ikwaqinisekisa ukuhamba okuthobayo ngoku, ngaloo ndlela ukuphuculwa kokusebenza ngokubanzi.
2.Umnqophiso wemodyuli yemodyuli
1.Source Cwangcisa:
Imodyuli yamandla kufuneka ihlawulwe ingqalelo ekhethekileyo kuba isebenza njengendawo yokuqala yamandla. Ukunciphisa intshayelelo yengxolo, indalo engqonge imodyuli yamandla kufuneka igcinwe icoceke kangangoko kunokwenzeka ukunqanda i-arverticy kwenyeI-Right-frequencyokanye izinto ezibuthathaka zengxolo.
2.ct kwi-chip yokuhambisa amandla:
Imodyuli yamandla kufuneka ibekwe kufutshane ne-chip ebonelelwe ngamandla njengoko kunokwenzeka. Oku kunganciphisa ilahleko kwinkqubo yothungelwano yangoku kwaye kunciphise iimfuno zendawo yenqwelomoya yenqwelomoya.
I-3.Heidipation Ingqwalaselo:
Imodyuli yoMbane inokuvelisa ubushushu ngexesha lokusebenza, ngoko ke kufuneka iqinisekiswe ukuba akukho ntendeli ngaphezulu kwendawo yokutshisa ubushushu. Ukuba kukho imfuneko, i-heatinks okanye abalandeli bayongezwa ukuze kupholile.
4.Uyayo,
Xa uphonononge, kuphephe ukwenza i-lops yangoku ukunciphisa ithuba lokuphazamiseka kwe-elektromagnetic.
II. UCwangciso lweNdawo yeNdiza
A. Uyilo lwe-stack stack
In Uyilo lwe-MCB MC, Uyilo lwe-stack stack yindawo ephambili ekufuneka uyiqwalasele umkhondo kunye nokusasazwa kwamandla.
a. Ukuqinisekisa iimpawu ezithethwayo zeplagi eziphantsi zeplagi kwaye ifumene ingxolo yengxolo yomhlaba, umgama phakathi kwamandla kunye neeplani zomhlaba akufuneki zidlule kwi-10mIl, iphakanyiswe ukuba ingaphantsi kwe-5mIl.
b. Ukuba inqwelomoya enye yamandla ayinakuphunyezwa, ungqimba lomhlaba unokusetyenziselwa ukubeka iplanethi yamandla. Amandla asondeleyo kunye neenqwelomoya ezisondeleyo zenza i-Canecitor yenqwelomoya kunye ne-Ac esezantsi kwe-AC i-AC iMveliso ye-AC kunye neempawu eziphezulu ze-free.
c. Khusela ekufuphi ezimbini, ngakumbi i-volomation enkulu ye-voltage, ukuthintela ukuvumela ingxolo. Ukuba akunakuthintelwa, yonyusa isithuba phakathi kwezi ntlobo zimbini zamandla kangangoko kunokwenzeka.
d. Iindiza zenkcazo, ngakumbi iindiza zereferensi, kufuneka zigcine iimpawu eziphantsi kwaye zinokuphelelwa ngamandla ohlanganisiweyo kunye nohlengahlengiso.
I-B.MMICPIDPUPROPUSTATION
a. For specific small-range power sources, such as the core working voltage of a certain IC chip, copper should be laid on the signal layer to ensure the integrity of the power plane, but avoid laying power copper on the surface layer to reduce noise radiation.
b. Ukukhethwa kobubanzi becandelo kufanele kube kufanelekile. Xa i-voltage ingaphezulu kwe-12v, ububanzi bunokuba ngama-20-30m; Ngaphandle koko, khetha i-12 ukuya ku -0m. Ububanzi becandelo phakathi kwemithombo yombane ye-analog kunye nemithombo yedijithali kufuneka yonyuswe ukuthintela amandla edijithali ukuba angaphazamiswa ngamandla e-alog.
c. Uthungelwano lwamandla olulula kufuneka lugqitywe kungqingwana lonyaka, kwaye iinethiwekhi zamandla ezinde kufuneka zibe namandla okucoca ongezelelweyo.
d. Indiza yamandla eqela kufuneka igcinwe rhoqo ukunqanda imilo engaqhelekanga ebangela ukunyuka kunye nokwanda kwamandla. Izahlulo ezinde nezincinci kunye nezahlulo zeDumbbell azivumelekanga.
c.plane yokucoca
a. Indiza yamandla kufuneka idityaniswe ngokusondeleyo nendiza yasemhlabeni.
b. Ngee-chips ezisebenzisa ii-frequency ezingaphezulu kwe-500mhz, ngokuyintloko ixhomekeke kwinqwelomoya yokucoca i-canect yodonga kwaye isebenzise indibaniselwano yokucoca amachaphaza. Iziphumo zokucoca i-clitha kufuneka ziqinisekiswe ngokungqinelane amandla.
c. Faka izikhuseli ukuze ufumane i-chieticals kwindiza yolawulo, njengokukhulisa i-Cawacitor ikhokelela kwaye akhulise i-vias ye-Canect, ukuqinisekisa ukuba amandla omhlaba ophantsi kakhulu kunamachaphaza ojoliso.
III. I-chip ye-chip ye-chip yamandla
I-chip yamandla sisiseko sezixhobo ze-elektroniki, kunye nokuqinisekisa ukugqibelela kwamandla ebaluleke kakhulu ekuphuculeni ukusebenza kunye nokuzinza. Ukunqongophala kwamandla Ukunqongophala kwamandla kwii-chips zamandla ikakhulu kubandakanya ukuphathwa kwe-chip amandla kunye nokubekwa ngokuchanekileyo kunye ne-wiring yeapatioputing. Oku kulandelayo kuya kuqwalaselwa kweenkcukacha kunye neengcebiso ezisebenzayo malunga nezi zinto.
A.Chip Sun Conse
Ukuphononongwa kwezikhonkwane zamandla e-chip yinxalenye ebalulekileyo yolawulo lwamandla. Ukubonelela ngoncedo oluzinzileyo lwangoku, kucetyiswa ukuba lukuqheliseni izikhonkwane zamandla, ngokubanzi kububanzi obufanayo njengezikhonkwane ze-chip. Ngokwesiqhelo, iUbuncinci bobubanziakufuneki ibe ngaphantsi kwe-8ml, kodwa ngenxa yeziphumo ezingcono, zama ukufezekisa ububanzi be-10mil. Ngokwandisa ububanzi bomvuzo, ukunyanzela kunokuncitshiswa, ngaloo ndlela kuncitshiswa ingxolo yamandla nokuqinisekisa ukuba ubonelelo lwangoku lusebenza kwiChip.
B.Qela kunye nokuHanjiswa kwee-Decoupling
I-Decoupiling Agecitors idlala indima ebalulekileyo kulawulo lwamandla kwiitshiphu zamandla. Kuxhomekeka kwiimpawu zeCapacit kunye neemfuno zesicelo, i-decoupling ixhonyiso ihlulwe yangamandla amakhulu kwaye amancinci.
a. Amandla amakhulu: Amandla amakhulu ahlala esasazwa ngokungqongqo kwi-chip. Ngenxa yerediyo yabo esezantsi kunye nerediyo enkulu yokufihla, banokucoca ingxolo engaphaya kwaye babonelela ngoncedo lwamandla.
b. Amandla amancinci: amachaphaza amancinci ane-frequency ephezulu kunye nerediyo encinci yokufihla, ukuze babekwe kufutshane kangangoko kunokwenzeka kwizikhonkwane ze-chip. Ukuzibeka kude kakhulu kunokuba kungayi kuguqula ingxolo enkulu, ukuphulukana nefuthe lokuhombisa. Ubeko oluchanekileyo luqinisekisa ukuba ukusebenza kwezixhobo ezincinci ekucoceni kwengxolo enkulu kusetyenziswe ngokupheleleyo.
I-C.wiring indlela yendlela yokuphelisa i-cacoupling
Ukuqhubela phambili ngokuphucula ingqibelelo yamandla, amandla amaninzi okuhombisa amachaphaza ahlala enxibelelana ne-parallel. Eyona njongo iphambili yale nto kukunciphisa isithuba esilinganayo se-Interch
Xa uqhekeza amandla amaninzi okuhombisa, kufuneka kuthathelwe ingqalelo ekubekweni kwe-vias ye-cacecitors. Eyona nto iqhelekileyo kukuphelisa i-vias namandla. Eyona njongo iphambili yoku kukunciphisa ukungahambi kakuhle phakathi kwe-decoupling. Qinisekisa ukuba ukungasebenzi kakuhle kuncinanana kune-ESL yeCapacitor enye, ukuze i-ESL isebenze emva kokuqhutywa kwamandla amaninzi ku-1 / n. Ngokuncitshiswa kokukhuphela, ukulungisa ukusebenza kakuhle kunokusetyenziswa ngokufanelekileyo, kuqinisekiswe ukuziikeka kwamandla.
Ubumekunye nokuqengqeleka kweemodyuli zombane, ucwangciso lwangaphakathi loyilo lwenqwelomoya, kunye nokuphathwa ngokuchanekileyo kwe-chip ye-chip namandla e-chip kunye ne-wiring ayinantsingiselo yoyilo lwe-elektroniki. Ngokusekwa kwesakhiwo esifanelekileyo kwaye sinokuqinisekisa uzinzo kunye nokusebenza kakuhle kweemodyuli zamandla, ukunciphisa ukuphazamiseka kwengxolo, kunye nokuphucula ukusebenza ngokubanzi. Uyilo lwe-stack stack kunye nesandla esikhulu sahlulahlula-hlula iimpawu zendlela yamandla, ukunciphisa uphazamiso lwengxolo yamandla. Ukuphathwa ngokufanelekileyo kwesolo se-chip yamandla kunye ne-wiring kunye ne-wiring kunye ne-decoupiling kunye ne-windows ibalulekile kulawulo lwamandla, ukuqinisekisa ukuhanjiswa okuzinzileyo kunye nokuzila okusebenzayo kwengxolo, ukuphucula ukusebenza kunye nokuzinza.
Kwimeko esebenzayo, imibandela eyahlukeneyo enjengobukhulu obukhoyo, ububanzi be-ranges, inani le-Vias, iziphumo zokunxibelelana, njl., Njl njl., Njl njl., Njl njl., Njl njl. Landela ukucaciswa koyilo kunye neendlela ezilungileyo zokuqinisekisa ulawulo kunye nokuphucula ingqibelelo yamandla. Kuphela yile ndlela sinokubonelela ngoncedo oluzinzileyo nolusebenzayo kwizixhobo ze-elektroniki, hlangabezane neemfuno zomsebenzi olwandayo, kunye nokuqhuba uphuhliso kunye nenkqubela phambili yetekhnoloji ye-elektroniki.
