I-Aluminium base pcb , sonke siyazi ukuthi i-aluminium iyinsimbi, ukuqhuba ngogesi;

Kanjani ingasetshenziswa njengoba PCB impahla?

Ngoba i-aluminium substrate yakhiwe ngezendlalelo ezintathu, okungukuthi: ucwecwe lwethusi, ungqimba lwe-insulation kanye ne-metallic aluminium. Njengoba kukhona ungqimba oluvikela, ngaphezu kokusebenza kokushiswa kokushisa, i-coefficient yokwanda okushisayo, ukuqhuba okushisayo, amandla, ubulukhuni, isisindo, isimo sendawo kanye nezindleko ze-substrate yensimbi kufanele futhi zibhekwe.

Ngokuvamile, uma kubhekwa izindleko nokusebenza kobuchwepheshe, i-aluminium substrate iyona ndlela efanelekile.Itholakala ipuleti le-aluminium 6061,5052,1060, njll. Izingxenye zensimbi nazo ziyatholakala ngezindawo eziphakeme ezishisayo, ezisebenza ngomshini, ezikagesi, nezinye izinto ezikhethekile, kepha zibiza kakhulu .

Kuvame ukubonwa ezinhlangothini zombili ze-aluminium substrate PCB. Uhlangothi olulodwa olunamafutha ekhava lushiselwe ngezikhonkwane ze-LED, kanti olunye uhlangothi lubonisa umbala wokuqala we-aluminium. Ngokuvamile, unamathisela oshisayo osetshenziswayo uzosetshenziswa bese uthintana nengxenye yokufudumeza eshisayo Enye yezinzuzo ezinkulu zama-aluminium substrates ngaphezulu kwendabuko i-FR-4 ukuthi bangakwazi ukuthwala i-current.And ephakeme yokuqhuba ukushisa, ukusebenza okuhle kokushiswa kokushisa.

I-aluminium substrate inganciphisa ukumelana nokushisa kubuncane, ukuze i-aluminium substrate ibe nokusebenza okuhle kakhulu kokuqhuba ukushisa; Uma kuqhathaniswa ne-substrate ye-ceramic, izakhiwo zayo zemishini zihle kakhulu.Ngaphezu kokusebenza okuhle kokushiswa kokushisa;

I-Aluminium substrate nayo inezinzuzo ezilandelayo:

Ngokuhambisana nezidingo zokuvikelwa kwemvelo kweRoHS, ifaneleka kakhulu inqubo ye-SMT enamandla aphezulu okuphatha njengamanje ukubhekana nokusabalalisa ukushisa kusikimu sokuklanywa kwesifunda, ukuze kuncishiswe izinga lokushisa lokusebenza kwemodyuli, kwandise impilo yensizakalo, futhi kuthuthukise ukuminyana kwamandla nokuthembeka;

Nciphisa ukuhlangana kwama-radiator nenye i-hardware (kufaka phakathi izinto ezisebenzisekayo zesikhombimsebenzisi), wehlise ivolumu yemikhiqizo, futhi unciphise nezindleko zehadiwe nezomhlangano; Lungiselela ukuhlanganiswa kwesekethe yamandla nokulawula isifunda.

Lokhu okungenhla kumayelana nezinzuzo ze-aluminium substrate, ngithemba ukuthi uzoyithanda! PCB imboni , siyakwamukela ukuthi uthinte imikhiqizo yethu ye-PCB ~
