Ultra Inokurumidza Kuchaja PCB Manufacturing Solutions

Highleap Electronics ikambani yakazara PCB yekugadzira uye yekuunganidza inoshandira mota, kufambiswa kwemashoko, simba, uye maindasitiri emagetsi evatengi. Pakati pekugona kwedu kwakasiyana, maPCB ekuchaja ekupedzisira anomiririra tekinoroji yekuburitsa magetsi-inogonesa zvese kubva pa100W majaja e-smartphone kusvika ku350kW EV supercharger anotsanangudza tarisiro yekuchaja yekumhanya.

Heavy Copper Solutions for Extreme Current Handling

Ultra-nekukurumidza kuchaja inoda mazinga azvino ayo aizoparadza akajairwa maPCB ipapo ipapo. Iyo 350kW charger inosundidzira 500+ amps nguva dzose-ikozvino inoda shanduko yePCB dhizaini maitiro ekubata zvakachengeteka uye nemazvo.

Isu tinoshandisa mhangura inorema kubva pa6oz kusvika 20oz ukobvu, kure nekure kwe1-2oz inoshandiswa mumagetsi akajairwa. Asi kugadzira mhangura inorema kunopa matambudziko akasiyana. Standard etching inorasikirwa nemazvo nemhangura yakakora, ichigadzira undercut iyo inonetesa maronda. Yedu inodzorwa-yakadzama milling inochengetedza ± 10% ukobvu kushivirira kunyangwe pahuremu hwe20oz.

Zvinokosha dhizaini kufunga kune yakakwirira ikozvino:

• Multiple parallel nzira dzinogovera yazvino mutoro
• Via arrays ane 50+ thermal vias pasi pezvibatanidza
• Yazvino density yakachengetedzwa pazasi 30A/mm²
• Copper balancing inodzivirira bhodhi warpage

Musiyano uripo pakati pekubudirira nekukundikana unowanzoenderana nekugoverwa kwemagetsi kwakakodzera. Ruzivo rwedu rwekuchaja maEV PCB runoshanda zvakananga kune zvinodiwa zvemagetsi izvi zvakanyanya, zvichiita kuti tivimbike kushanda kwemakumi emakore.

Thermal Management paKilowatt Scale

Pa350kW, kunyangwe 98% kunyatsoshanda kunoreva 7kW yekupisa kwemarara-yakaenzana nezvinoomesa bvudzi zvinomwe munzvimbo diki pane laptop. Pasina dhizaini yakasarudzika yekupisa, zvikamu zvaizotadza mukati memasekonzi.

Traditional thermal vias hazvina kukwana panguva idzi simba nhanho. Isu tinoshandisa akazara ekudziya ekuvaka anosanganisira mhangura-yakaputirwa mbiya ye3x zvirinani conductivity, yakazadzwa vias inobvisa mhepo, uye simbi-core substrates kana FR-4 yasvika painogumira. Aluminium substrates inopa 5W/mK thermal conductivity, nepo ma substrates emhangura achiunza 380W/mK—pamusoro pe1000x zviri nani pane standard FR-4.

Kune mashandisirwo anonyanya kuoma, kutonhodza kwemvura kunova chinhu chinodiwa. Tinogadzira maPCB ane gadziriro yakabatanidzwa yekutonhodza—nzvimbo dzekuisa maplate anotonhora, kugadzirisa material interface, uye maseketi ekutarisa tembiricha akaparadzaniswa. Mamwe madhizaini epamusoro anosanganisira nzira dzekutonhodza zvakananga muchimiro chePCB, kunyange izvi zvichida hunyanzvi hwekugadzira hwatakagadzira kuburikidza nemapurojekiti edu ePCB ane simba rakawanda.

Wide-Bandgap Semiconductors Inogonesa Revolution

Silicon carbide (SiC) uye gallium nitride (GaN) semiconductors yakashandura ultra-fast kuchaja kubva murabhoritari kuda kuziva kune chokwadi chekutengesa. Midziyo iyi inoshandura 10x nekukurumidza kupfuura silicon ine kurasikirwa kwakanyanya kuderera, zvichiita kuti kushanda uye simba remagetsi rinodiwa kune inoshanda-yekukurumidza kuchaja.

Asi yakafara-bhendi michina inoda yakasarudzika PCB dhizaini. Pa50V/ns switching kumhanya, mamirimita ese ekutsvagira zvinhu. Parasitic inductance iyo isinganyanyi kukanganisa silicon IGBTs ikozvino inokonzeresa inoparadza voltage overshoot neSiC neGaN.

Layout optimization ye-wide-bandgap zvishandiso:

• Vertical power loops uchishandisa maseru ari pedyo
• Via arrays kune mashoma inductance shanduko
• Gedhi dhiraivha inoteedzera seinodzorwa impedance mitsetse
• Kuiswa kwechikamu kunoderedza loop nzvimbo

Hunyanzvi hwedu hwekugadzira maPCB esimba reGaN hunotungamira sarudzo idzi dzakakosha dzekugadzira, tichiona kushanda kwakasimba pakumhanya kwakanyanya kwekuchinja uku tichichengetedza kushanda kwepamusoro pe98%.

Smart Charging Protocol Integration

Ultra-nekukurumidza kuchaja haisi yekungounza magetsi mbishi chete — inoda kutaurirana zvine hungwaru pakati pechaja nemudziyo. Masisitimu emazuva ano anotsigira USB Power Delivery Yakawedzerwa Simba Range (EPR) kusvika ku240W, proprietary protocols seOPPO's 150W SuperVOOC, uye mota-ku-grid bidirectional kuchaja.

Protocol yega yega inoda maPCB chaiwo. USB-PD inoda kudzora impedance chaiyo pamitsetse yekutaurirana yeCC uku ichiibvisa kubva kumagetsi ane voltage yakawanda. Protocol dzeproprietary dzinowanzoda machipisi ekusimbisa e encrypted uye maseketi e handshake akasarudzika. Magadzirirwo edu ePCB e fast charging controller anobatanidza zvinodiwa izvi zvakasiyana-siyana pasina matambudziko.

Iyo PCB inofanirwa kubata yakakwirira-kumhanya kwedhijitari kutaurirana mamilimita kubva kilowatt-level magetsi switching-an electromagnetic kuenderana kunotyisa. Isu tinowana izvi kuburikidza nekungwarira dhizaini stackup dhizaini, hurongwa hwepasi ndege segmentation, uye yakazara kudzivirira pakati pesimba uye chiratidzo madomasi.

MaSystems ekuchengetedza eMasimba Akanyanya Simba

Pamatanho emagetsi aya, chengetedzo inodarika kuteedzera-zvakakosha kune yega yega sarudzo yekugadzira. Multiple dziviriro akaturikidzana anodzivirira kukundikana kwakaipisisa kunogona kuisa mungozi vashandisi kana michina.

Yakakwana kudzivirira kushandiswa:

• Overcurrent yekuona inopindura mumamicroseconds
• Arc kutadza kuona kune matambudziko ekubatanidza
• Ground kukanganisa kukanganisa mukati me20ms
• Thermal monitoring panzvimbo dzakawanda
• Zvipingamupinyi zvekuzviparadzanisa zvinopfuura 4kV rating

Nzvimbo ine simba guru inova yakakosha. Kune masisitimu e1000V, tinochengetedza daro re15mm rekukwira - 50% kupfuura zvinodiwa zvishoma. Nzvimbo dzekuparadzanisa pakati pemasekete ekutanga neechipiri dzinovimbisa kuchengetedzeka kunyangwe paine kusvibiswa kana kutadza kwezvikamu. Nheyo idzi dzekugadzira, dzakagadziriswa kuburikidza nekugadzira kwedu power module PCB , dzinovimbisa kushanda kwakachengeteka pasi pemamiriro ese ezvinhu.

Manufacturing Excellence for Reliability

Ultra-nekukurumidza kuchaja maPCB anoshanda kumucheto kwezvinogoneka mumuviri, achida kugadzira kunaka kupfuura zvakajairika zvemagetsi.

Bhodhi rega rega rinoitwa kuyedzwa kwakadzama kunosanganisira 100% kusimbiswa kwemagetsi, kuyedza-kuzviparadzanisa nevamwe, kusimbiswa kwebhasikoro, uye x-ray ongororo yezvakavanzwa. Isu tinochengetedza kuteedzera kuzere kubva kune zvigadzirwa kuburikidza nekubatanidza, tichitsigira 10+ gore waranti inodiwa nehurongwa uhu.

Unyanzvi hwedu hwepamusoro hunosanganisira kutevedzana kwezvikamu zvakaiswa mukati, tekinoroji yeHDI yehuwandu hwakanyanya, uye maitiro akasarudzika ezvigadzirwa zvekunze. Ingave kugadzira ma prototypes kana scaling kusvika kuzviuru zvemayuniti, tinoramba tiine mwero wakafanana. Unyanzvi uhwu hunoshanda muhuwandu hwedu hwese, kubva kuPCB yekuchaja isina waya kusvika kuAI data center power PCB applications.
