Dhizaini yePCB Yakavimbika Yekupa Simba reMidziyo yeMagetsi

Peji rino rinotaura nezvenjodzi dzekuvimbika mumabhodhi emagetsi emudziyo. Kuti uwane ongororo yechikamu, verenga ongororo yebhodhi redunhu remagetsi ; kuti uwane ongororo inouya, marekodhi emaitiro, uye kudzora kudzokorora maodha, shandisa maitiro eHighleap ePCB quality assurance process.

ziviso

Munyika ine simba remagetsi, akadhindwa edunhu mabhodhi (PCBs) anoita basa rakakosha, achigonesa kushanda kweasingaverengeki emidziyo yemagetsi. Ingave yako smartphone, komputa, kana maindasitiri emidziyo, maPCB ndiwo magamba asina kusimba anosimbisa nyika yedu yanhasi. Pakati pekushanda kwavo magetsi ePCB, chinhu chakakosha chinokonzeresa kushandura nekugadzirisa simba remagetsi kuti ive nechokwadi chekushanda kwakavimbika kwemidziyo iyi. Mugwaro rino rakazara, isu tichanyura mukati menyika yePCB magetsi ekupa, tichiongorora mhando dzawo, nzira dzekudzivirira, uye akasiyana maitiro.

MaPCB emagetsi anoda kurapwa nekungwarira kwe creepage, switching loops, thermal paths, uye output current; zvinodiwa izvi zvinofanirwa kuongororwa kuburikidza nekugadzira power PCB uye kusimbiswa panguva yePCBA assembly.

Mhando dzePCB Power Supplies

PCB magetsi emagetsi anogona kuiswa zvakanyanya mumhando mbiri huru: mutsara magetsi emagetsi uye switched-modhi magetsi emagetsi (SMPS).

Linear Power Supplies

Linear magetsi ekushandisa anoshandisa ma transformer kushandura alternating current (AC) kuita yakananga ikozvino (DC). Ivo vanozivikanwa nekureruka kwavo uye kugona. Zvisinei, dzinowanzova dzakakura uye dzisina kukodzera hukuru uye huremu-sensitive applications. Linear magetsi emagetsi anowana imba yavo mumaindasitiri masisitimu uye mamwe maapplication uko saizi isiri inomisa chinhu.

Switched-Mode Power Supplies (SMPS)

SMPS, kune rumwe rutivi, inosimudzira transistors kushandura AC kuita DC. Iwo anoratidzirwa nehukuru hwawo compact uye huremu huremu, zvichiita kuti ive yakakodzera kune inotakurika michina senge mbozhanhare nemakomputa. Kushanda nesimba uye kuita zvakasiyana-siyana kweSMPS kwaita kuti ive sarudzo yekuenda kune yazvino, yepamusoro-simba maapplication.

Kuchengetedza Simba Rako rekupa

Kuve nechokwadi chekuvimbika uye hupenyu hurefu hwePCB simba rekupa kwakakosha. Nzira dzinoverengeka dzekudzivirira dzinouya kuzochengetedza magetsi uye dunhu rese.

Spikes uye Surges

Spikes uye ma surges muvoltiji anogona kukanganisa simba remagetsi uye yakabatana dunhu. A spike inokurumidza, inopinza kuwedzera kwemagetsi, nepo kuvhiya kuri kuwedzera kwenguva refu voltage. Zviitiko izvi zvinogona kukonzerwa nezvinhu zvakaita semidziyo isina kunaka, kudzimwa kwemagetsi, kana kurohwa nemheni. Kudzivirira kubva kutyisidzira uku, kuvhiya uye spike vadziviriri vanoita semutsetse wekutanga wekudzivirira.

Power Supply Circuit Protection

Voltage regulators vanoita basa rakakosha mukudzivirira kubva kune spikes uye masurges. Ivo vanovimbisa kuti magetsi anopa yakagadzikana uye yakachengeteka voltage uye yazvino nhanho kuPCB. Pamusoro pezvo, mafirita anobvisa isingadiwe AC ruzha kubva kuDC magetsi sosi, kuchengetedza kutendeseka kwedunhu.

Overcurrent uye Overvoltage Dziviriro

Mafuse uye mabreaker edunhu zvinhu zvakakosha zvekuchengetedza kubva kune overcurrent uye overvoltage mamiriro. Mafusi anoita semidziyo yekuchengetedza iyo inovhiringa dunhu kana voltage kana yazvino ichipfuura mazinga akachengeteka. Circuit breakers inoshanda chinangwa chakafanana uye inobvisa dunhu mune zvisingawanzo kukwirira zvazvino, kudzivirira PCB kubva kupfupi maseketi.

Electromagnetic Kupindira uye Static Magetsi Dziviriro

Electromagnetic interference (EMI) uye static magetsi anogona kuunza kutyisidzira kukuru kune magetsi uye dunhu rese. EMI mafirita anoshandiswa kubvisa kukanganisa kunogona kukanganisa kushanda kwedunhu. Pamusoro pezvo, zvigadziro zvekugadzika zvinovimbisa kuti chero machaji akamira akadzimwa zvakachengeteka, kudzivirira kukanganisa kuPCB uye magetsi.

Overloading Dziviriro

Kuwedzeredza kunoitika kana dunhu rinokweva simba rakawanda kupfuura iro magetsi anogona kupa. Kuti udzivise izvi, magetsi anosanganisira maseketi anomisa simba anodzora simba rekubuda, kuchengetedza PCB kubva pakuremedza.

Kupisa Kuchengetedza

Kupisa kwakanyanya kunogona kukanganisa kushanda uye kuvimbika kwemidziyo yemagetsi, kusanganisira magetsi. Thermal cut-off michina inosanganiswa mumagetsi ekuona kupisa uye kukanganisa dunhu kana zvichidikanwa, kudzivirira kukanganisa.

Reverse Polarity Kudzivirirwa

Reverse polarity, uko dunhu remagetsi rakabatana munzira isiriyo, rinogona kukonzera kukanganisa kumatunhu edunhu. Kudzikamisa njodzi iyi, magetsi emagetsi anoratidza madhidhiyo anoita kuti ikozvino kuyerera nenzira kwayo chete, kuchengetedza PCB kunyangwe muzviitiko zve reverse polarity.

Inofananidzira PCB Power Supplies

PCB magetsi ekupa anogona kuratidzwa zvakare zvichienderana nechimiro chavo chemuviri uye kushanda.

Pa-board uye Off-board Power Supply

Musiyano uripo pakati pe-bhodhi uye kunze-bhodhi magetsi ekushandisa uri munzvimbo yavo chaiyo ine chekuita nePCB. Off-board magetsi emagetsi ari kunze kwePCB uye akakodzera kune yakaderera-simba maapplication. Sezvineiwo, pane-bhodhi magetsi emagetsi akabatanidzwa muPCB pachayo, ichiita kuti ive yakanaka kune yakakwirira-simba maapplication.

Centralized kana Distributed Power Supply

Simba rekugovera mukati mePCB rinogona kuiswa pakati kana kugoverwa. Pakati pemagetsi emagetsi anodyisa zvishandiso zvese paPCB kubva kune imwechete sosi, nepo akagoverwa magetsi ekushandisa anoshandisa akawanda masosi. Zvepakati zvepakati zvinowanzo shandiswa mune yakaderera-simba maapplication, nepo zvakagoverwa zvekushandisa zvakajairwa mune yakakwirira-simba mamiriro.

Isolated kana Non-imwechete Power Supply

Isolated magetsi emagetsi akapatsanurwa kubva kune AC tambo yemagetsi, inosimudzira chengetedzo. Magetsi asina-akasarudzika anobatana zvakananga kune AC tambo yemagetsi. Magetsi akasarudzika anofarirwa kune yakaderera-simba maapplication nekuda kweawo ekuwedzera kuchengetedza maficha.

Yakagadziriswa kana Isina Kudzoreredzwa Magetsi

Magetsi anodzorwa anochengetedza kubuda kwakadzikama, kuve nechokwadi kugadzikana. Magetsi asina kudzorwa anopa kubuda kwemagetsi anochinja. Zvishandiso zvinodzorwa zvinosarudzwa kune mashoma-simba maapplication, nepo zvisina kudzorwa zvekushandisa zvinowana kushandiswa mune yakakwirira-simba marongero.

mhedziso

Munzvimbo yemagetsi, simba rePCB rinobuda sechinhu chakakosha chinosimbisa kushanda kwezvigadzirwa zvemagetsi. Kunyangwe iri mutsara magetsi emagetsi masisitimu eindasitiri kana switched-mode magetsi emagetsi anotakurika, kunzwisisa nuances yePCB magetsi ekupa kwakakosha pakugadzira akasimba uye akavimbika emagetsi masisitimu. Iine nzira dzekudzivirira dzakakodzera munzvimbo uye nekunzwisisa kwakajeka kwehunhu hwePCB magetsi ekupa, mainjiniya anogona kuona kuti zvigadzirwa zvemagetsi zvinoramba zvichisimbisa nyika yedu yakabatana zvisina musono. Sarudza iyo magetsi emagetsi anowirirana nezvaunoda chaizvo, uye rega simba rakavimbika riyerere kuburikidza nemaPCB ako, uchityaira hunyanzvi kumberi.

Pakuronga kugadzirwa, zvinobatsirawo kuenzanisa nyaya iyi nedhizaini yePCB mount transformer uye dziviriro yedunhu mudhizaini yePCB usati wapedzisa kugadzira kana kugadzira pasuru.
