Umhlahlandlela Wezindleko ze-PCB Yokunikezwa Kwamandla e-AC-DC

Izindleko ze-AC-DC power supply PCB zibuswa yizinto ezintathu — i-bill yezinto zokwakha (ikakhulukazi ama-magnetics, ama-bulk capacitor kanye ne-controller), izinketho zokwenziwa (isisindo sethusi, inani lezendlalelo, ibanga lezinto zokwakha), kanye nokuhlolwa okudingekayo (i-Hipot kanye nokuhlolwa kokusebenza kuyunithi ngayinye) — ngokusetha ivolumu ukuthi ubunjiniyela besikhathi esisodwa kanye namathuluzi kusakazeka kanjani kulo lonke i-oda. Ngokungafani nebhodi le-logic lapho izindleko ze-PCB ezingenalutho ziholela khona, izindleko zokunikezwa kwamandla zivame ukuhlala ezingxenyeni kanye nesikhathi sokuhlola. I-Highleap isiza amakhasimende ukufinyelela umgomo wezindleko ongokoqobo ngokubukeza ukuthi imali iya kuphi ngempela futhi ibone izinguquko eziyinciphisa ngaphandle kokwenza ibhodi libe buthaka.

Usebenzela ekuqondeni izindleko ebhodini lamandla? Thumela umklamo wakho kanye nevolumu sizokukhombisa ukuthi izindleko zimi kuphi nokuthi unganciphisa kanjani. Thola incazelo yezindleko.

Yini Ebangela Izindleko Ze-PCB Yamandla Ngempela?

Ukuze ulawule izindleko zokunikezwa kwamandla kagesi kufanele uqale wazi ukuthi uhlala kuphi, futhi impendulo iyamangaza abathengi abavela kuma-elekthronikhi edijithali. Ebhodini le-logic, i-PCB engenalutho ivame ukuba yindleko eyinhloko; ekunikezelweni kwamandla, izingxenye zivame ukwedlula konke okunye, ngoba i-transformer, ibhange lama-capacitor e-electrolytic aphezulu kanye nesilawuli esikhethekile kuyizingxenye ezibizayo. Ukwenziwa ngokwako - ithusi elisindayo, izendlalelo eziningi, izinto ezingcono - kunezela nezindleko zangempela, futhi ukuhlolwa kuyinto yangempela ngoba ukuqinisekiswa kwamandla aphezulu kuthatha isikhathi. Ukwazi lokhu kukuvimbela ukuthi wenze kahle into engalungile: ukusika izindleko zebhodi engenalutho ngenkathi ungazinaki i-BOM eyidlula.

Umshayeli ngamunye uphendula kuma-lever ahlukene, yingakho ingxoxo yezindleko kufanele ibhekane nawo ngokwehlukana. Izindleko zokukhiqiza zihamba ngesisindo sethusi, inani lezingqimba, usayizi webhodi kanye nebanga lezinto ezibonakalayo. Izindleko zezingxenye zihamba ngokukhethwa kwezingxenye, ukutholakala kanye nevolumu. Izindleko zokuhlola zihamba ngokumbozwa kanye nokulungiswa. Ukuphatha "izindleko" njengenombolo eyodwa engahlukanisiwe kuholela ekukhungathekeni; ukuyiphatha njengeqoqo labashayeli, ngamunye ene-lever yakhe, yilokho okukuvumela ukuthi uhambise inani eliphelele.

Izindleko Eziyinhloko Ezibangela Izindleko

Isifundo esiwusizo ukuhlasela izindleko lapho zimi khona ngempela. Eziningi zamandla kusho ukuthi i-BOM kuqala, ukukhetha ukukhiqiza kwesibili kanye nezindleko zesikhathi esisodwa kuya kweyesithathu - hhayi okuphambene nalokho, lapho abathengi abaphatha ibhodi elingenalutho njengezindleko eziyinhloko begcina bechitha khona umzamo.

Indlela Izindleko Eziwela Ngayo Ngomthamo

Ivolumu ishintsha ezomnotho zokuphakelwa kwamandla ngaphezu kwanoma yisiphi esinye isici, futhi hhayi emgqeni oqondile. Izindleko zesikhathi esisodwa - ubunjiniyela, amathuluzi, ama-stencil, izinto ezisetshenziswayo - aziguquki kungakhathaliseki ukuthi zingakanani, ngakho-ke uma ziphansi zibusa intengo ngeyunithi ngayinye futhi uma ziphezulu zicishe zinyamalale. Ngaphezu kwalokho, intengo yezingxenye ithuthuka ngobuningi njengoba ukuthenga komkhiqizi kuqhubekela ekuphulweni kwentengo okungcono kuma-magnetics nama-semiconductors, futhi ukuhlanganiswa kuba ngcono njengoba isikhathi sokusetha sisakazeka emabhodini amaningi. Umphumela uba yi-curve yezindleko ngeyunithi ngayinye eyehla kakhulu ekuqaleni bese iba yi-bump.

Ukuqonda ukuma kwaleyo jika yikho okukuvumela ukuthi uhlele ngokuhlakanipha. I-prototype noma inani lokuhlola lizohlala libukeka libiza ngeyunithi ngayinye ngoba izindleko ezihleliwe azinandawo yokucasha; lokho kuyinto evamile, akuyona uphawu lwesilinganiso esibi. Inombolo enengqondo yindleko ngeyunithi ngayinye kumthamo wakho wangempela wokukhiqiza, futhi umbuzo onengqondo uwukuthi ivolumu yakho ikuphi kujika — ngoba ukusuka, ake sithi, amakhulu kuya ezinkulungwaneni kuvame ukuvula ikhefu lentengo elishintsha yonke indaba yebhizinisi lomkhiqizo.

Indlela Izindleko Eziziphatha Ngayo Kuwo Wonke Umthamo Wevolumu

Ngakho umbuzo ofanele wezindleko awukaze uthi “libiza malini ibhodi elilodwa” lilodwa — kodwa uthi “libiza malini ibhodi ngomthamo engizowusebenzisa ngempela.” Ukucaphuna inani lakho langempela lokukhiqiza, nokubuza ukuthi ikhefu lentengo elilandelayo likuphi, yindlela oguqula ngayo ijika levolumu libe yinzuzo yakho esikhundleni sokumangala ngalo.

I-BOM Yilapho Imali Ikhona

Ngenxa yokuthi izingxenye zivame ukulawula izindleko zokunikezwa kwamandla, inani lezinto zokwakha liyindawo enenzuzo ephezulu yokusebenza - futhi omazibuthe kanye nomlawuli ngokuvamile kuyizinto eziphambili. I-transformer yangokwezifiso ithwala izindleko zamathuluzi kanye neyunithi ngayinye; isilawuli esitholakala kuphela sithwala intengo kanye nengozi; ama-capacitor e-electrolytic ane-voltage ephezulu ahlanganisa umklamo. Ukunciphisa amasenti ambalwa ku-resistor akushintshi lutho, kodwa ukukhetha okuhlakaniphile kukazibuthe noma isilawuli esinomthombo wesibili ofanelekayo kungashukumisa kokubili izindleko kanye nengozi yokunikezwa ngendlela enenjongo.

Umsebenzi wezindleko ze-BOM osebenza kahle kakhulu nawo awukhangi kangako: ukuhlanganisa izinombolo zezingxenye ukuze ingxenye efanayo yenze imisebenzi eminingi, ukushintshana okufanele ukuze ungabi yisithiyo sentengo yomhlinzeki oyedwa, ukukhetha omaginethi abajwayelekile kunokwezifiso lapho ukusebenza kuvumela khona, kanye nokuthenga isikhathi kuya ekuphukeni kwentengo yevolumu. Akukho kulokhu okuphazamisa ibhodi - ukusebenza kahle kuphela. Umkhiqizi owazi imakethe yezingxenye zamandla angavame ukuphakamisa ukushintshana okugcina ukusebenza ngenkathi kunciphisa izindleko noma ingozi, okuyingxoxo okufanele ibe nayo ngaphambi kokuba i-BOM ivalwe.

Lapho Unganciphisa khona Izindleko Ngaphandle Kokusika Amakhona

Kukhona umugqa ohlanzekile phakathi kokunciphisa izindleko nokunciphisa amakhona, futhi ukuhlala ohlangothini olufanele lwalo kuyikhono eliphelele. Ukunciphisa izindleko okusemthethweni kususa imfucuza — ithusi elisindayo kunalokho okudingwa yimanje, izendlalelo ezingadingi i-topology, izinga lezinto ezibonakalayo ngale kweqiniso lokushisa, izingxenye ezenziwe ngokwezifiso lapho ezijwayelekile zisebenza khona, ukwakheka kwamaphaneli okusebenzisa indawo yamabhodi okulahla imfucuza. Ngayinye yalezi zehlisa izindleko ngenkathi ishiya ukuphepha kwebhodi, ukusebenza kanye nokuthembeka kwalo kungathintekile, ngoba ubukhokhela ikhono ongalisebenzisanga.

Izinyathelo ezingezansi yizo ezinciphisa ngokuthembekile izindleko zokunikezwa kwamandla ngaphandle kokuwenza buthaka. Ingxoxo evamile ukuthi zilungisa umklamo ngokwezidingo zawo zangempela kunokususa umkhawulo ibhodi eliwudinga ngempela — okuyiwona kanye umehluko obahlukanisa nomnotho wamanga esigabeni esilandelayo.

• Ithusi losayizi ofanele: sebenzisa ithusi elisindayo kuphela ezindleleni zamandla aphezulu, hhayi ibhodi lonke.
• Usayizi ofanele we-stackup: lahla izendlalelo ezingadingeki yi-topology kanye nohlelo lwe-EMI.
• Qondanisa izinto ozidingayo: sebenzisa i-Tg ephezulu noma i-metal-core kuphela lapho impilo yokushisa idinga khona.
• Yenza izingxenye zifane: khetha ama-magnetic ajwayelekile futhi uhlanganise izinombolo zezingxenye lapho ukusebenza kuvumela khona.
• Lungiselela ukwenziwa kwamaphaneli: ukuthuthukisa isivuno sebhodi ngephaneli ukuze kuncishiswe izindleko zokukhiqiza nokuhlanganisa.
• Thenga kuze kube yivolumu: ukuthengwa kwezingxenye zesikhathi ukuze kufinyelele ukuphuka kwentengo ngenani lakho langempela.

Uma kwenziwa ndawonye, ​​lokhu kungathatha izindleko zangempela ebhodini lamandla ngenkathi kusadlula zonke izivivinyo ezazenza ngaphambili. Isihluthulelo ukuthi ngayinye isuse okungaphezulu, hhayi umkhawulo - yingakho kuphephile ukukulandela futhi ukuncishiswa esigabeni esilandelayo akuphephile.

Izomnotho Zamanga Ezibiza Kakhulu Kamuva

Ezinye "izinto ezongayo" ziyizingibe, kanti ebhodini lamandla ziyabiza ngoba imodi yokwehluleka ibhodi elithunyelwa bese lihluleka. Ukungacacisi kahle ithusi ukuze kongiwe izindleko zokukhiqiza kukhiqiza ukunikezwa okushisa futhi kukhule kusenesikhathi. Ukweqa i-100% Hipot ukuze kuhlolwe isampula kusindisa isikhathi sokuhlola kodwa kuthumela amabhodi anesithiyo sokuzihlukanisa esingakaze siqinisekiswe ngawodwana. Ukukhetha ingxenye engafaneleki eshibhile kungonga amasenti ngeyunithi ngayinye kuze kube yilapho leyo ngxenye iphela noma ifika ingekho emthethweni bese imisa umugqa wakho. Ngayinye yalezi yehlisa isilinganiso futhi ikhuphule izindleko zangempela.

Isizathu sokuthi lezi zifanele ukubizwa ngokuthi zinhle ngoba ziyasebenza — kuze kube yilapho zingasebenzi. Ugesi odlula ebhentshini kodwa wehluleke endaweni eshisayo, noma iqembu elihluleka ukuhlolwa kokuphepha kumakhasimende, libiza kakhulu kunemali yokukhiqiza noma yokuhlola egciniwe, ngokubuyiselwa, ukulungiswa kabusha kanye nedumela. Ukulungiswa kwezindleko kwangempela kususa imfucuza; umnotho wamanga ususa umkhawulo kanye nokuqinisekiswa okugcina ibhodi elikhulu liphephile futhi lithembekile. Ukwazi umehluko yilokho okuvikela isabelomali sakho kanye nomkhiqizo wakho.
