Izixazululo Zokukhiqiza ze-PCB zokushaja ngokushesha

I-Highleap Electronics iyinkampani ehlanganisa yonke i-PCB ekhiqiza izimoto, ezokuxhumana, ezamandla kanye nezimboni zama-electronics. Phakathi kwamakhono ethu ahlukahlukene, ama-PCB ashaja ngokushesha amele unqenqema lobuchwepheshe bokulethwa kwamandla—okuvumela yonke into kusukela kumashaja ama-smartphone angu-100W kuya kumashaja amakhulu angu-350kW EV achaza kabusha okulindelwe ukushaja okulindelwe.

Izixazululo Zethusi Elinamandla Zokuphatha Kwamanje Okudlulele

Ukushaja okushesha kakhulu kudinga amazinga amanje angacekela phansi ama-PCB ajwayelekile ngaso leso sikhathi. Ishaja engu-350kW iphusha ama-amps angu-500+ ngokuqhubekayo—okwamanje okudinga izindlela zokuklama ze-PCB eziguquguqukayo ukuze iphathe ngokuphepha nangempumelelo.

Sisebenzisa ithusi elisindayo elisukela ku-6oz ukuya ku-20oz ukujiya, ukudlula kude u-1-2oz osetshenziswa kuma-electronics ajwayelekile. Kodwa ukwenza ithusi elisindayo kunezinselele eziyingqayizivele. Ukubhala okujwayelekile kulahlekelwa ukunemba ngethusi eliwugqinsi, kudala i-undercut eyenza imikhondo ibe buthaka. Ukugaya kwethu okujule okulawulwayo kugcina ukubekezelela ukujiya okungu-±10% ngisho nasezisindweni ezingama-20oz.

Ukucatshangelwa kwedizayini ebalulekile yamanje ephezulu:

• Izindlela eziningi ezihambisanayo zisakaza umthwalo wamanje
• Ngezinhlu ezinama-thermal angu-50+ ngaphansi kokuxhumana
• Ukuminyana kwamanje kugcinwa ngaphansi kuka-30A/mm²
• Ukulinganisa kwethusi kuvimbela i-warpage yebhodi

Umehluko phakathi kwempumelelo nokwehluleka uvame ukuncika ekusabalalisweni kwamanje okulungile. Okuhlangenwe nakho kwethu kwe-PCB yokushaja i-EV kusebenza ngqo kulezi zidingo zamanje eziqine kakhulu, okuqinisekisa ukusebenza okuthembekile amashumi eminyaka.

Ukuphathwa kwe-Thermal ku-Kilowatt Scale

Ku-350kW, ngisho nokusebenza kahle okungu-98% kusho u-7kW wokushisa okulahlwayo—okulingana nokomisa izinwele eziyisikhombisa endaweni encane kunekhompyutha ephathekayo. Ngaphandle kwesakhiwo esishisayo esikhethekile, izingxenye zizohluleka phakathi kwamasekhondi.

Indlela yokwejwayelekile yokungena eshisayo azanele kulawa mazinga wamandla. Sisebenzisa ukwakheka okushisayo okubanzi okuhlanganisa imiphongolo egoqwe ngethusi ukuze kuqhutshekwe ngcono izikhathi ezingu-3x, i-vias egcwalisiwe esusa izikhala zomoya, nama-metal-core substrates lapho i-FR-4 ifinyelela umkhawulo wayo. Ama-Aluminium substrates ahlinzeka nge-thermal conductivity engu-5W/mK, kuyilapho ama-copper substrates aletha u-380W/mK—ngaphezu kuka-1000x kangcono kune-FR-4 evamile.

Ngezinhlelo zokusebenza ezidinga kakhulu, ukupholisa uketshezi kuba yimpoqo. Siklama ama-PCB anokulungiselela ukupholisa okuhlanganisiwe—izindawo zokufaka amapuleti abandayo, ukwenza ngcono izinto ezisetshenziswayo ezisetshenziswa ekushiseni, kanye namasekethe okuqapha amazinga okushisa ahlukanisiwe. Eminye imiklamo ethuthukisiwe ifaka iziteshi zokupholisa ngqo esakhiweni se-PCB, yize lokhu kudinga amakhono okukhiqiza akhethekile esiwathuthukisile ngamaphrojekthi ethu e-PCB anomthamo ophezulu wamandla.

Ama-Semiconductors e-Wide-Bandgap anika amandla i-Revolution

I-Silicon carbide (SiC) kanye namasemiconductors e-gallium nitride (GaN) aguqule ukushaja okushesha kakhulu ukusuka ekufuneni ukwazi kwaselabhorethri kuya eqinisweni lezentengiso. Lawa madivayisi ashintsha izikhathi ezingu-10 ngokushesha kune-silicon enokulahlekelwa okuphansi kakhulu, okuvumela ukusebenza kahle nokuminyana kwamandla okudingekayo ukuze kushajwe ngokushesha okukhulu.

Kepha amadivaysi e-wide-bandgap adinga ukwakheka okuhlukile kwe-PCB. Ngezivinini zokushintsha ezingu-50V/ns, yonke imilimitha yokulandelela ibalulekile. I-Parasitic inductance eyathikameza kancane ama-silicon IGBTs manje idala ukudlula kwamandla kagesi abhubhisayo nge-SiC ne-GaN.

Ukulungiselelwa kwesakhiwo kumadivayisi e-wide-bandgap:

• Amalophu wamandla aqondile esebenzisa izendlalelo eziseduze
• Ngokusebenzisa ama-arrays woshintsho oluncane lwe-inductance
• Ukulandelela idrayivu yesango njengemigqa ye-impedance elawulwayo
• Ukubekwa kwengxenye kunciphisa indawo yeluphu

Ubuchwepheshe bethu bokukhiqiza i-GaN power PCB buqondisa lezi zinqumo ezibalulekile zokwakheka, buqinisekisa ukusebenza okuzinzile ngesivinini esikhulu sokushintsha ngenkathi bugcina ukusebenza kahle okungaphezu kuka-98%.

I-Smart Charging Protocol Integration

Ukushaja okushesha kakhulu akukhona nje ukulethwa kwamandla angahluziwe—kudinga ukuxhumana okuhlakaniphile phakathi kweshaja nedivayisi. Amasistimu esimanje asekela i-USB Power Delivery Extended Power Range (EPR) kufika ku-240W, izimiso eziyisisekelo ezifana ne-OPPO's 150W SuperVOOC, kanye nokushaja okuqondiswa kabili kwemoto kuya kugridi.

Iphrothokholi ngayinye idinga ukusetshenziswa kwe-PCB ethile. I-USB-PD idinga ukulawulwa okuqondile kwe-impedance emigqeni yokuxhumana ye-CC ngenkathi iwahlukanisa ne-power rails enamandla aphezulu. Amaphrothokholi obunikazi avame ukudinga ama-chip okuqinisekisa abethelwe kanye namasekethe akhethekile okuxhawulana. Imiklamo yethu ye-PCB yokulawula ukushaja okusheshayo ihlanganisa lezi zidingo ezahlukahlukene kalula.

I-PCB kufanele iphathe amamilimitha okuxhumana kwedijithali anesivinini esikhulu ukusuka ekushintsheni kwamandla ezinga le-kilowatt—iphupho elibi elihambisana nogesi. Sifinyelela lokhu ngomklamo wokupakisha wesendlalelo esicophelelayo, ukuhlukaniswa kwendiza yaphansi kwamasu, nokuvikela okuphelele phakathi kwamandla nezizinda zesignali.

Amasistimu Okuphepha Amazinga Amandla Adlulele

Kulawa mazinga wamandla, ukuphepha kweqa ukuthobela—kubalulekile kuzo zonke izinqumo zedizayini. Izendlalelo eziningi zokuvikela zivimbela ukwehluleka okuyinhlekelele okungafaka engozini abasebenzisi noma okokusebenza.

Ukuqaliswa kokuvikela okuphelele:

• Ukutholwa kwamanje kuphendula kuma-microsecond
• Ukutholwa kwephutha kwe-Arc ngezinkinga zesixhumi
• Ukuphazamiseka kwephutha eliphansi phakathi kuka-20ms
• Ukuqapha okushisayo ezindaweni eziningi
• Izithiyo zokuzihlukanisa ezedlula izilinganiso ze-4kV

Isikhala se-voltage ephezulu siba yinto ebalulekile. Ezinhlelweni ze-1000V, sigcina amabanga okucwila angu-15mm—50% ngaphezu kwezidingo eziphansi. Izikhala zokuhlukaniswa ngokomzimba phakathi kwezifunda eziyinhloko nezesibili ziqinisekisa ukuphepha ngisho noma kukhona ukungcola noma ukwehluleka kwezingxenye. Lezi zimiso zokuklama, ezihlaziywe ngokukhiqizwa kwe-PCB yethu yamandla , ziqinisekisa ukusebenza okuphephile ngaphansi kwazo zonke izimo.

Ukukhiqiza Okuncomekayo Kokwethenjelwa

Ama-PCB ashaja ngokushesha kakhulu asebenza emaphethelweni alokho okungenzeka ngokomzimba, adinga ukusebenza kahle kokukhiqiza okudlula izinto zikagesi ezijwayelekile.

Ibhodi ngalinye lenziwa ukuhlolwa okuphelele okuhlanganisa ukuqinisekiswa kukagesi okungu-100%, ukuhlolwa okungaba khona kakhulu ukuzehlukanisa, ukuqinisekiswa kokuhamba ngebhayisikili elishisayo, nokuhlolwa kwe-x-ray ukuze kutholakale ukukhubazeka okufihliwe. Sigcina ukulandeleka okugcwele okuvela ezintweni zokusetshenziswa ngokuhlanganisa, sisekela iziqinisekiso zeminyaka eyi-10+ ezidingwa yilezi zinhlelo.

Amakhono ethu athuthukile afaka phakathi i-lamination elandelanayo yezingxenye ezifakiwe, ubuchwepheshe be-HDI bokuxinana okuphezulu, kanye nezinqubo ezikhethekile zezinto ezingavamile. Kungakhathaliseki ukuthi sikhiqiza ama-prototype noma silinganisa amayunithi ayizinkulungwane, sigcina amazinga afanayo aqinile. Lobu buchwepheshe busabalala kulo lonke iphothifoliyo yethu, kusukela ku-PCB yokushaja okungenantambo kuya kuzinhlelo zokusebenza ze-PCB zamandla esikhungo sedatha se-AI.
