Amaphutha e-Aluminium PCB: Izinkinga Ezivamile kanye Namasu Okuvimbela

Ukuqonda Ukukhubazeka kwe-Aluminium PCB kuzinhlelo zokusebenza zamandla aphezulu

Ama-PCB e-aluminium asebaluleke kakhulu kumadivayisi kagesi anamandla amakhulu, izinhlelo zokukhanyisa ze-LED, kanye namamojula kagesi lapho ukushabalalisa ukushisa okusebenzayo kubalulekile khona. Kodwa-ke, amaphutha e-aluminium pcb angalimaza kakhulu ukuthembeka nokusebenza kulezi zinhlelo zokuphatha ukushisa. Ukwakhiwa okuyingqayizivele kwama -PCB ensimbi eyinhloko kwethula izindlela ezithile zokwehluleka ezihlukile kumabhodi endabuko e-FR-4, okwenza ukuvimbela amaphutha kube yinto ebalulekile kubakhiqizi kanye nonjiniyela bokuklama abasebenza ngezimoto, izimboni, kanye ne-electronics zabathengi.

Amaphutha Abalulekile e-Aluminium PCB: Izinkinga ze-Delamination

Izimbangela ze-Delamination ku-Aluminium PCB

Ukuhlukanisa kumelela enye yeziphambeko ezinkulu kakhulu ze-aluminium pcb, ezenzeka lapho i-foil yethusi ihlukana nesendlalelo se-dielectric noma lapho i-dielectric ihlukana nesisekelo se -aluminium . Lokhu kwehluleka kuvela ekucindezelekeni okukhulu kokushisa ngesikhathi sokugoqa, ukunamathela okunganele phakathi kwezingqimba ezilaminethiwe, noma ukuvezwa isikhathi eside kokujikeleza kokushisa. Ukuphakamisa umkhondo wethusi okubonakalayo, ukuvula isekethe, kanye nokuhlukaniswa kukagesi okuphazamisekile kubonisa izinkinga zokuhlukanisa.

Ukuvimbela Ukukhubazeka Kwe-Delamination

Ukuvimbela kudinga ukulawula okuqinile kwamaphrofayili okushisa okugeleza kabusha kwe-solder, ukuqinisekisa ukuthi izinga lokushisa eliphakeme lihlala ngaphakathi kokucaciswa kwezinto ezibonakalayo. Amasu abalulekile okuvimbela ahlanganisa:

• Ukulawula ukushisa - Gcina amaphrofayili okugeleza kabusha ngaphansi kwezinga lokushisa lokushintsha ingilazi ye-dielectric ukuvimbela ukuhlukana okubangelwa ukucindezeleka.
• Ukukhetha izinto - Sebenzisa izinto zokwakha zekhwalithi ephezulu ezinezilinganiso ezishisayo ezifanelekile zendawo yakho yohlelo lokusebenza.
• Cindezela ukulungiselelwa - Lawula ingcindezi ye-lamination, izinga lokushisa, kanye nesikhathi sokuhlala ukuze uqinisekise ukuhlangana okuphelele phakathi kwezingqimba.

Amaphutha e-Aluminium PCB: Izinkinga Ezihlangene Ze-Solder

Izinkinga Ezihlangene Ezihlangene ze-Solder ku-MCPCB

Ubuqotho be-solder joint buletha izinselele ezihlukile kuma-PCB assemblies ensimbi ngenxa yokushisa okuphezulu kwe-aluminium . Izinkinga ezivamile ze-solder joint ku-mcpcb zifaka phakathi ama-solder abandayo, ukubopha phakathi kwama-pads aseduze, kanye nokumanzisa okunganele okubangelwa ukushabalaliswa kokushisa okusheshayo. Lezi ziphazamiso zivela kuma-curve angalungile okugeleza kabusha ahlulekayo ukubala isisindo sokushisa sesisekelo se-aluminium, i-oxidation yobuso be-pad, noma ukukhethwa kwe-solder alloy okungahambisani.

Izixazululo ze-Solder Joint Defects

Ukusebenzisa iphrofayela enembayo yokushisa enezindawo zokucwiliswa ezinwetshiwe kunxephezela umphumela wokucwilisa ukushisa kwe-substrate. I-Surface finishes njenge-ENIG noma isiliva yokucwiliswa ihlinzeka ngokuthengiswa okuphezulu kakhulu uma kuqhathaniswa ne-HASL, kuyilapho unamathisele we-solder ongenamthofu oklanyelwe izinhlelo zokusebenza zokuphatha okushisayo uqinisekisa ukwakheka okuhlangene okungaguquki kuyo yonke inhlangano.

I-Warping and Gonding: Amaphutha e-Structural Aluminium PCB

Ukuqonda i-Warping ku-Aluminium PCB

Ikhasi le-warpage lebhodi lihlanganisa inkinga yekhwalithi ye-PCB ebalulekile ethinta isivuno somhlangano kanye nokwethembeka kwesikhathi eside. I-Warping ku-aluminium pcb kwenzeka ngenxa yokwanda okushisayo okungalingani phakathi kwezendlalelo zethusi, i-dielectric, ne-aluminium, noma ukusatshalaliswa kwethusi eli-asymmetric endaweni yonke yebhodi. Ukushisa okungalingani ngesikhathi sokugeleza kabusha kwandisa lezi zingcindezi, okuholela ekukhoneni noma ukusonteka okuhlanganisa ukubekwa kwengxenye futhi kungase kubangele ukuqhekeka kwejoyinti le-solder ngokuhamba kwesikhathi.

Ukuvimbela Ukukhubazeka Kwekhasi Lempi

Amasu okuklama nokukhiqiza anciphisa amathuba e-warpage:

• Umklamo we-Symmetrical - Linganisa amaphethini ethusi nokusabalalisa isisindo kuzo zombili izindawo zebhodi.
• Ukulawula ukujiya - Khetha ugqinsi olufanele lwesisekelo se-aluminium (1.5mm kuya ku-3.0mm) ngokusekelwe kusayizi webhodi kanye nezidingo ezishisayo.
• Ukushisa okufanayo - Sebenzisa amaphrofayili okugeleza kabusha alawulwayo ngokusatshalaliswa kokushisa nokwesekwa okufanele kwebhodi ngesikhathi sokusebenza okushisayo.

I-Thermal Stress and Overheating Aluminium PCB Defects

I-Thermal Stress PCB Izinkinga Kuzicelo Ezinamandla Aphezulu

Ingcindezi yokushisa eyeqile imele inselele eqhubekayo lapho ukuminyana kwamandla kugxilisa ukushisa ezindaweni zendawo. Izinkinga ze-Thermal stress pcb zibonakala njengokuguga kwe-dielectric esheshayo, ukukhathala okushisayo kwamajoyinti e-solder, kanye nokuphelelwa yisikhathi ngaphansi kokuhamba ngebhayisikili okuphindaphindiwe. Ukusabalalisa ukushisa okunganele noma ukujiya kwe-aluminium okunganele kwehluleka ukuphatha imithwalo eshisayo ngokuphumelelayo ezinhlelweni ezifunwayo.

Izixazululo Zokuphatha Okushisayo

Ukuvimbela kuqala esigabeni sokuklama ngokulingisa okushisayo ukuze kuhlonzwe izindawo ezishisayo nokuthuthukisa ukubekwa kwengxenye. Ukwenyuka kwe-aluminium substrate ukujiya kuthuthukisa amandla okusabalalisa ukushisa, kuyilapho ukufaka ama-vias ashisayo ezindaweni zezingxenye zamandla aphezulu kuthuthukisa ukudluliswa kokushisa okuqondile. Ukukhetha okufanelekile kwe-interface eshisayo phakathi kwe-PCB ne-heatsink kuqinisekisa ukuchithwa kokushisa okusebenzayo kwezinga lesistimu.

Ukwelashwa Kwangaphandle kanye Neziphambeko Ze-Aluminium PCB

I-Surface evamile kanye nokukhubazeka kokunamathisela

Ukwelashwa okungaphezulu kanye nokulimala kokufakwa kwesekethe kuthinta ngqo ukuthengiswa nokusebenza kukagesi. Izinkinga zihlanganisa ukushumeka kwe-copper okungaphelele okushiya izikhindi ezisele, ukucwiliswa ngokweqile okunciphisa imikhondo kudlulele ukubekezelelwa, kanye ne-surface oxidation eyonakalisa i-pad solderability. Lawa maphutha avela ngenxa yokungaguquki kwesisombululo sokuhlanganisa, ukulawulwa kwenqubo okunganele, noma isikhathi eseqile phakathi kokwenziwa nokuhlanganisa.

Ukulawulwa Kwekhwalithi Yokukhubazeka Okungaphezulu

Amasistimu okuhlola okuzenzakalelayo abamba okungahambi kahle ekuqaleni kokukhiqizwa. Izinqubo ezilawulwayo zokufaka i-impedance ngokuqapha kwesikhathi sangempela zigcina ukunemba kobukhulu, kuyilapho ukuqedwa kwendawo evikelayo kusetshenziswa ngokushesha ngemva kokucwiliswa kuvimbela i-oxidation. Isitoreji ezindaweni ezinomswakama ophansi esinezinto ezivimbela umswakama silondoloza ikhwalithi ephezulu kuze kube yilapho kwenziwa umsebenzi wokuhlanganisa.

Izilawuli Zezinto Nezinqubo

Ukuvimbela ukungasebenzi okusebenzayo kuhlanganisa ukukhethwa kwezinto ezibonakalayo nobunjiniyela benqubo kukho konke ukukhiqiza. I-aluminium substrates yezinga eliphezulu enezinhlelo ze-dielectric eziqinisekisiwe zinikeza isisekelo samabhodi athembekile. Izilawuli ezibalulekile zifaka:

• Lamination nemingcele - Gcina izinga lokushisa lokucindezela, ingcindezi, kanye nesikhathi ngaphakathi kwamafasitela aqinisekisiwe ukuze kube nesibopho esingaguquki.
• Ukuqinisekisa ukugeleza kabusha - Qinisekisa amaphrofayili okushisa usebenzisa izilinganiso zangempela zokushisa zebhodi, hhayi izilungiselelo ze-ovini zodwa.
• Imithethonqubo yenhlanzeko - Qinisekisa ukucutshungulwa okungangcoliswanga ukuze kuvinjelwe ukunamathela kanye nokwehluleka ukuthengiselana.

Izindlela Zokuhlola Ezithuthukile

Ukuhlola okuzenzakalelayo kokubona kukhomba okudidayo kwendawo kanye nokuhluka kobukhulu, kuyilapho ukuhlolwa kwe-X-ray kuveza ukubola kwangaphakathi kanye nokungabi bikho kokuhamba kwe-thermal. Ukuhlolwa kwe-Flying probe kuqinisekisa ukuqhubeka kukagesi ngaphandle kwezidingo zokulungiswa, okubalulekile ikakhulukazi kuma-prototype kanye nokuqaliswa kokukhiqiza kwevolumu ephansi.

Idizayini Yokukhiqiza

Idizayini yezimiso zokwenziwa ezisetshenziswa ngesikhathi sokuhlela ivimbela amaphutha amaningi e-aluminium pcb ngaphambi kokuthi ukukhiqizwa kuqale. Isikhala esanele phakathi kokulandelelwa kwamanje okuphezulu kuvimbela i-thermal crosstalk, kuyilapho usayizi wephedi ofanele uvumela izici ezishisayo ze-aluminium substrate. Ukulinganisa ithusi okulawulwayo kuzo zonke izakhiwo zamaphaneli kunciphisa amandla e-warpage kusukela esigabeni sokuklama.
