I-Heavy Copper PCB vs I-IMS PCB: Isiphi Isixazululo Somklamo Onamandla Aphakeme Esifanelana Nesicelo Sakho?

Isingeniso

Amasistimu kagesi anamandla amakhulu abhekana nezinselele zokuklama ezibalulekile ekulawuleni ukunqanyulwa kokushisa namandla okuthwala amanje ngesikhathi esisodwa. Izinhlelo zokusebenza ezisebenza ngaphansi kwezimo eziphezulu, zamanje, nezimo zokushisa eziphakeme zidinga izixazululo ze-PCB ezeqa amandla ebhodi avamile.

Izindlela ezimbili ezivelele zibhekana nalezi zidingo: ubuchwepheshe be-PCB yethusi esindayo buthembele ezingqimbeni zethusi ezijiyile kakhulu, kuyilapho i-IMS PCB (Insulated Metal Substrate) isebenzisa amapuleti esisekelo sensimbi ukuze kuqhutshwe ukushisa. Ukuqonda umehluko wesakhiwo, izici zokushisa, kanye nemikhawulo yokusebenza kwe- PCB yethusi esindayo kanye ne -IMS PCB kwenza izinqumo ezinolwazi ezilinganisela izidingo zokusebenza kanye nokusebenziseka kokukhiqiza kanye nemikhawulo yezindleko.

I-Heavy Copper PCB vs IMS PCB: Uhlolojikelele Lokwakha

Umehluko wezakhiwo phakathi kwe-PCB yethusi esindayo kanye ne-IMS PCB ithonya ngokuqondile amandla azo okusebenza nokufaneleka kohlelo lokusebenza.

Ukwakhiwa kwezinto

I-PCB yethusi esindayo yakha phezu kwe-FR4 noma i-polyimide substrates ejwayelekile enezendlalelo zethusi ezisukela ku-2oz kuya ku-20oz noma ngaphezulu. Lokhu kwakhiwa kugcina ukuhambisana nezinqubo zokukhiqiza ze-PCB ezivamile ezinezendlalelo eziningi ngenkathi kukhulisa kakhulu ukujiya kwethusi ezingqimbeni zokusatshalaliswa kwamandla.

I-IMS PCB isebenzisa ipuleti lesisekelo le-aluminium noma lethusi njengesisekelo esiyinhloko, esimbozwe ngesendlalelo sokufakelwa kwe-dielectric kanye nesendlalelo sesekethe se-copper foil ngokuvamile esiphakathi kuka-1oz no-3oz. Isendlalelo se-dielectric sinikeza ukwahlukaniswa kukagesi ngenkathi kuvumela ukudluliselwa kokushisa. Uma ukhetha phakathi kokwakhiwa kwe-PCB yethusi ne-aluminium , qhathanisa indlela yamanje kagesi edingekayo kanye nesakhiwo sokudlulisa ukushisa kunokuphatha uhlobo lwensimbi kuphela njengenqubo yokukhetha.

I-Thermal Pathway Architecture

I-PCB yethusi esindayo iqhuba ukushisa ngezindiza zethusi ezijiyile kanye nezivinini zokushisa ezixhumanisa izendlalelo ziqonde phezulu. Ukushisa kusakazeka eceleni kwezindiza zethusi ngaphambi kokunyamalala ebusweni bebhodi noma kuma-heatsink angaphandle.

I-IMS PCB inikeza indlela yokushisa eqondile eqondile esuka ezingxenyeni idlula ungqimba oluncane lwe-dielectric iye esisekelweni sensimbi, esisebenza njenge-heatsink ehlanganisiwe. Ukushisa kusuka ku-1 kuya ku-8 W/mK kuye ngokukhethwa kwezinto ze-dielectric.

Amakhono Okumiswa Kwesendlalelo

I-PCB yethusi esindayo isekela ukwakhiwa okuyinkimbinkimbi kwezingqimba eziningi ngezingqimba ezingu-4, 6, 8, noma ngaphezulu, okuvumela umzila wesifunda oyinkimbinkimbi kanye nezakhiwo zomhlabathi. I-IMS PCB isalokhu ikhawulelwe kakhulu ekulungiselelweni okunezinhlangothi ezimbili noma okunezinhlangothi ezimbili ngenxa yemingcele yokukhiqiza.

Ukuphatha Okushisayo: I-Heavy Copper PCB vs IMS PCB

Ukusebenza okushisayo kumelela umehluko obaluleke kakhulu phakathi kwalobu buchwepheshe obubili bezinhlelo zokusebenza zamandla aphezulu.

I-IMS PCB Heat Dissipation

I-IMS PCB ihamba phambili ekusebenzeni kahle kokudlulisa ukushisa okuqondile ngepuleti layo lesisekelo lensimbi, elihlinzeka ngokusebenza okushisayo cishe izikhathi eziyi-100 ezinkulu kune-FR4. Le ndlela yokushisa eqondile ibonakala iphumelela kakhulu emithonjeni yokushisa egxilile njengama-LED wamandla, ama-MOSFET array, nezilawuli eziqondile lapho ukulawulwa kwezinga lokushisa okuhlanganayo kubaluleke kakhulu.

Izinzuzo eziyinhloko ze-thermal zihlanganisa:

• Indlela eshisayo emfishane – Ukugeleza kokushisa okuqondile kusuka ezingxenyeni ezithile kuya esisekelweni sensimbi kunciphisa amazinga okushisa okuhlangana.
• Ukucwilisa ukushisa okuhlanganisiwe - Isisekelo se-aluminium noma sethusi sisebenza izindima ezimbili njenge-substrate ne-spreader eshisayo.
• Umklamo oshisayo owenziwe lula - Iqeda ukushisa okuyinkimbinkimbi ngama-arrays adingekayo ekwakhiweni kwe-PCB evamile.

Heavy Copper PCB Thermal Distribution

I-PCB yethusi esindayo isebenzisa izindiza zethusi eziwugqinsi ukuze zisabalalise ukushisa eceleni kwendawo yonke yebhodi ngaphambi kokuhlakazeka okuqondile. Izendlalelo zethusi zika-4oz kuya ku-10oz zidala ukushisa okukhulu okusabalalisa ukushisa kusuka emithonjeni egxilile kuya ezindaweni ezibanzi, ehlisa izinga lokushisa eliphakeme.

Lokhu kusakazeka okushisayo okuvundlile kuba yinzuzo ezinhlelweni zokusebenza ezinemithombo yokushisa esabalaliswe kaningi noma lapho ukusabalalisa kwezinga lokushisa okufanayo kuyo yonke inhlangano kubalulekile. Okushisayo okuminyene ngama-array axhuma ithusi elingaphezulu ezindizeni zangaphakathi zaphansi kwakha izindlela eziningi ezishisayo ezihambisanayo.

Idatha Yokusebenza Ngokuqhathanisa

Kuzinhlelo zokusebenza ezingaphezu kuka-100W ukuchithwa kwamandla, i-IMS PCB ngokuvamile ifinyelela izinga lokushisa eliphansi le-junction elingu-30-40% uma liqhathaniswa nezakhiwo ezijwayelekile ze-Heavy Copper zokulawula i-hotspot yendawo. Kodwa-ke, i-PCB yethusi esindayo ene-thermal ethuthukisiwe nge-array inikeza ibhalansi esebenza kahle yokushisa kumasistimu anokusabalalisa kwamanje okuyinkimbinkimbi yezindlela eziningi.

Ikhono Lamanje Lokuthwala Nokuthembeka

Ukusebenza kukagesi nokucatshangelwa kokuthembeka kwesikhathi eside kuhlukanisa kakhulu i-PCB yethusi enzima kanye nokuqaliswa kwe-IMS PCB.

I-Heavy Copper PCB Amandla amanje

Ubuchwepheshe be-PCB yethusi esindayo bubhekana ngqo nezidingo zamanje eziphezulu ngogqinsi lwethusi. I-trace yethusi engu-4oz enesilinganiso esingu-10mm ububanzi ithwala ngokuphepha u-20-25A ngokuqhubekayo, kuyilapho ithusi elingu-10oz kububanzi obufanayo liphatha u-40-50A ngokukhuphuka kwezinga lokushisa okwamukelekayo ngaphansi kwezimo zokupholisa komoya eziphoqelekile.

Izendlalelo zangaphakathi ekwakhiweni kwe-multilayer Heavy Copper zisabalalisa okwamanje kuzo zonke izindlela ezihambisanayo, zinciphisa ukumelana nokwehla kwamandla kagesi kumanethiwekhi okusabalalisa amandla. Izindiza ezinamandla ezizinikele zethusi ezizinikezele ezingqimbeni zangaphakathi zihlinzeka ngokusatshalaliswa kwe-impedance ephansi ebalulekile ezinhlelweni zokusebenza zamanje.

Ukuphatha Kwamanje kwe-IMS PCB

I-IMS PCB, ekhawulelwe izendlalelo zethusi ezacile, ifinyelela umthamo wamanje ophansi ngokuphelele ngobubanzi bokulandelela kodwa inxephezela ngokukhipha ukushisa okuphezulu. Ukudlulisa okushisayo okusebenzayo kusisekelo sensimbi kuvumela ukuminyana okuphezulu kwamanje ngaphambi kokufinyelela imikhawulo yokushisa uma kuqhathaniswa namabhodi ajwayelekile e-FR4 anogqinsi olulingana nethusi.

Ukuqhathanisa Ukuthembeka Kokuxhumana

Ukwakhiwa kwe-PCB yethusi esindayo kusebenzisa embozwe ngezimbobo ezinemigqomo yethusi ewugqinsi, kwakha ukuxhumana okuqinile okumelana nokuhamba ngebhayisikili okushisayo kanye nengcindezi yokusebenza. Isakhiwo sethusi esiqinile sinikeza ukuqiniswa kwemishini okunciphisa ukuguquguquka kwebhodi.

I-IMS PCB yethula ukucatshangelwa kokuthembeka okuyingqayizivele okuhlobene ne-coefficient of thermal expansion (CTE) ukungafani phakathi kwesisekelo se-aluminium, ungqimba lwe-dielectric, nesekethe yethusi. Lokhu kuhluka kungabangela ukucindezeleka ekuhlanganiseni kwe-solder ngesikhathi sokuhamba ngebhayisikili eshisayo, okudinga ukukhethwa kwengxenye ngokucophelela nezinqubo zokuhlanganisa ukuze kuqinisekiswe ukwethembeka kwesikhathi eside.

Ukukhiqiza Nezindleko: I-Heavy Copper PCB vs IMS PCB

Izindlela zokukhiqiza kanye nezici zezomnotho zithonya kakhulu ukukhetha kobuchwepheshe phakathi kwalezi zixazululo.

I-Heavy Copper PCB Fabrication

Ukwenziwa kwe-PCB yethusi elinzima kudinga izinqubo ezikhethekile ezifaka:

• Imijikelezo ye-electroplating enwetshiwe ukuze kuzuzwe ukufakwa kwethusi eliwugqinsi kusukela ku-4oz ukuya ku-20oz.
• Izinqubo ze-etching eziguquliwe ezinezikhathi zokucwiliswa ezinde ukuze kulawuleke ukushuba kwethusi okwandisiwe.
