I-PCB Enamandla Yethusi Yokunikezwa Kwamandla Kwamanje Nokushisa

Isingeniso

Ubuchwepheshe be-PCB yethusi esindayo , obuchazwa ubukhulu bethusi obuyi-105 μm noma ngaphezulu, sebubalulekile kuma-electronics anamuhla ezimboni. Lawa mabhodi wesekethe akhethekile abhekana nezinselele eziyisisekelo zezicelo zamandla aphezulu lapho ama-PCB ajwayelekile ehluleka khona ukuletha ukusebenza okwanele.

Ezimbonini zamandla kagesi kanye nezinhlelo ze-inverter, i-PCB yethusi esindayo yezinhlelo zokusebenza zokunikezwa kwamandla inika amandla ukusebenza okuthembekile ngaphansi kwengcindezi enkulu kagesi kanye ne-thermal ngenkathi igcina ubuqotho besakhiwo. Lesi sihloko sihlola amapharamitha wedizayini ebalulekile kanye nokucatshangelwa kokukhiqiza kwezindawo zezimboni ezifunayo.

Izidingo Zamandla Ezimboni kanye Nezinhlelo Zokuguquguqula

Izidingo Zamanje Eziphezulu Neziminyana Zamandla

Izimpahla zikagesi zezimboni, ama-motor drive, kanye nemishini yokushisela zisebenza emazingeni amanje adala ukulahlekelwa okukhulu kwe-I²R kanye nokuhlushwa kokushisa. Imiklamo ye-PCB yama-elekthronikhi kagesi kumele ivumelane nobuningi bamanje obungabangela ukuthi amabhodi ajwayelekile ashise ngokweqile noma ahluleke. Idizayini ye-PCB ye-inverter yama-frequency drive aguquguqukayo ivame ukuphatha amakhulu ama-ampere ngokusebenzisa izakhiwo ezincane, okudala izinselele zokuphathwa kokushisa ezidinga izixazululo ezikhethekile ze-PCB zethusi esindayo.

Ukucindezeleka Kwezemvelo Nokusebenza

Izimo zezimboni zingaphansi kwamabhodi esekethe ekugibeleleni okushisayo okushisayo, ukudlidliza komshini, nokuchayeka kwamakhemikhali. Amamojula wamandla ezikhungweni zokukhiqiza asebenza ngokuqhubekayo emazingeni okushisa aphakeme kuyilapho egcina ukuhlukaniswa kukagesi phakathi kwezingxenye zamandla kagesi aphezulu. Ukwakhiwa kwe-PCB yendabuko akunawo amandla okwenza okushisayo kanye nokuqina kwemishini okudingekayo ekuthembekeni kwendawo yezimboni, okuholela ekuhlulekeni ngaphambi kwesikhathi ezinhlelweni zokuphakelwa kwamandla abalulekile.

Kungani Heavy Copper PCB for Power Supply Applications

Ikhono Lokuthwala Eliphezulu Lamanje

Ukwakhiwa kwe-PCB yethusi esindayo kuvumela izindlela ezibanzi ze-conductor ngaphandle kokukhulisa usayizi webhodi, kunciphisa ngokuqondile ukulahlekelwa okuphikisayo kanye nokwehla kwamandla kagesi. Inqwaba yethusi ekhuphukile isabalalisa okwamanje ngokulinganayo endaweni ephakeme ye-PCB yamanje, ivimbela ukushisisa kwendawo okwehlisa isithunzi samalunga e-solder nokuthembeka kwengxenye:

Leli khasi likhawulelwe kumabhodi okunikezwa kwamandla kagesi aphezulu adinga ithusi elisindayo. Ngesigaba sebhodi elijwayelekile, qala ngokubuka konke kwebhodi lesekethe lokunikezwa kwamandla ; ukuze uthole imingcele yokubeka, ukuqopha, kanye nokukhiqiza, sebenzisa ukukhiqizwa kwe-PCB yethusi elisindayo okuhlobene.

• Ukulahlekelwa kwe-I²R okuncishisiwe – Ithusi eliwugqinsi linciphisa ukushisisa okuqinile ezindleleni zamanje.
• I-voltage ephansi yehla - I-conductivity ethuthukisiwe igcina ama-voltage okusebenza azinzile ngaphansi komthwalo.
• Ngisho nokusabalalisa kwamanje - Ukulandela okubanzi kuvimbela izindawo ezishisayo kanye nokugxila kwengcindezi yokushisa.

I-Superior Thermal Management

I-thermal conductivity ethuthukisiwe yezendlalelo zethusi eziwugqinsi kudala izindlela ezisebenzayo zokusabalalisa ukushisa ukusuka kuma-semiconductors wamandla kuya emaphethelweni ebhodi noma ezindaweni ezikhwezwayo. I-PCB yethusi esindayo yamamojula okunikezwa kwamandla isebenza njengesinki esihlanganisiwe sokushisa, inciphisa amazinga okushisa e-junction kuma-IGBT, ama-MOSFET, nama-diode amandla. Lokhu kuthuthukiswa kokusebenza okushisayo kwandisa isikhathi sokuphila kwengxenye futhi kuvumela imiklamo ephezulu yokuminyana kwamandla ezinhlelweni zokusebenza ze-inverter.

Amandla Omshini Athuthukisiwe

I-copper mass eyengeziwe iqinisa izakhiwo zebhodi ngokumelene ne-warping ngesikhathi sokugeleza kabusha kanye nokuhamba ngebhayisikili okushisayo. Izimbobo eziphucwe ezinemiphongolo yethusi esindayo zibonisa ukumelana okuphakeme nokuqhekeka kokucindezeleka okushisayo uma kuqhathaniswa nokwakhiwa okujwayelekile. Ukuthembeka kwe-PCB ekufakweni kwezimboni zokudlidliza okuphezulu kuncike kulokhu kuqiniswa kwemishini, ikakhulukazi kumabhodi amakhulu aphethe izingxenye zamandla asindayo.

Ukucatshangelwa Kwedizayini Ye-Heavy Copper PCB Power Supply

Ukukhethwa Kokuqina Kwethusi

Ukukhetha isisindo esifanele sethusi kudinga ukuhlaziywa kwamazinga amanje aqhubekayo kanye nezingqinamba zokushisa. Idizayini ye-PCB yamamojula wamandla ngokuvamile isebenzisa ithusi elingu-3 oz kuzinhlelo zokusebenza zamandla aphakathi nendawo afika ku-50A, kuyilapho iziguquli zamandla aphezulu zingacacisa u-6-10 oz wezindlela zamanje eziyinhloko. Ugqinsi lwethusi luthinta ngqo ubunkimbinkimbi nezindleko zokukhiqiza, okudinga ukulungiselelwa okunokulinganisela ngokumelene nezidingo zikagesi emiklamo yokuphakelwa kwamandla.

Landela Ububanzi Nokuminyana Kwamanje

Amazinga e-IPC-2152 ahlinzeka ngezibalo zokukhuphuka kwezinga lokushisa ngokusekelwe ku-conductor geometry nesisindo sethusi. Ngezinhlelo zokusebenza ze-PCB yethusi elisindayo, abaklami kufanele balandise imikhawulo yamanje yokuminyana kuyilapho begcina isikhala esanele. Ama-thermal vias ngaphansi kwezingxenye zamandla adala izindlela zokushisa eziqondile eziya ezindizeni zethusi zangaphakathi, kuthuthukisa kakhulu ukunqanyulwa kokushisa ekwakhiweni kokuphakelwa kwamandla kwezendlalelo eziningi.

I-Insulation kanye Nokuhambisana Nokuphepha

Amandla kagesi ezimbonini kufanele ahlangabezane nezidingo eziqinile zokuhlukaniswa kukagesi ezichazwe amazinga e-UL kanye ne-IEC:

• Ibanga le-creepage - Ukwenyuka kwesikhala kuvimbela ukulandelwa komhlaba phakathi kokulandela i-high-voltage.
• Izidingo zokusula - Izikhala zomoya zigcina amandla e-dielectric ezindaweni ezingcolile.
• Ukukhetha izinto - Izilinganiso eziphezulu ze-CTI ziqinisekisa ukusebenza kwe-insulation yesikhathi eside.
