I-PCB, igama lesiShayina liphrintiwe ibhodi lesifunda, elaziwa nangokuthi ibhodi lesifunda eliphrintiwe, liyizinto ezibalulekile ze-elekthronikhi, ukuxhaswa kwezinto ze-elekthronikhi, izinto ze-elekthronikhi yithwala lokuxhuma kagesi.Ngenxa yokuthi zenziwa ngobuchwepheshe bokuphrinta ngogesi, zibizwa Amabhodi wesifunda aphrintiwe.Okulandelayo, umakhi we-Yong Ming Sheng Umkhiqizi we-Yongmingsheng uchaza imbangela yokunyuka kwezinga lokushisa le-aluminium substrate PCB.

Ukuhlaziywa kwesilinganiso sokushisa kokushisa kwebhodi lesifunda eliphrintiwe

Isizathu esiqondile sokukhuphuka kwamazinga okushisa kwe-PCB ku-aluminium substrate ubukhona bamadivayisi okusetshenziswa kwamandla esifundeni. Ukusetshenziswa kwamandla kwamadivayisi kagesi kuyahlukahluka kuye ngamazinga ahlukahlukene, futhi amandla okushisa ayahluka ngokusetshenziswa kwamandla.

Izimo ezimbili zokushisa zikhuphuka emabhodini aphrintiwe:

(1) ukukhuphuka kwezinga lokushisa lendawo noma ukukhuphuka kwezinga lokushisa endaweni enkulu;

(2) Ukuphakama kwesikhashana noma kwesikhathi eside kwezinga lokushisa.

Ngokuvamile, ukusetshenziswa kwamandla kagesi okushisayo kuhlaziywa kulezi zici ezilandelayo:

1.Electrical amandla Consumpti

(1) Hlaziya ukusetshenziswa kwamandla endaweni ngayinye;

(2) Hlaziya ukwabiwa kwamandla ebhodini le-PCB.

Isakhiwo sebhodi lesifunda eliphrintiwe

(1) Ubukhulu bamabhodi wesifunda aphrintiwe;

(2) Okuprintiwe wesifunda ibhodi izinto.

Indlela yokufaka ibhodi yesifunda ephrintiwe

(1) Imodi yokufaka (njengokufakwa okuqondile, ukufakwa okuvundlile);

(2) isimo sokuvalwa kanye nebanga ukusuka kukasayizi.

4.heat conduction

(1) ukufaka irediyetha;

(2) ukuqhutshwa kwezinye izingxenye zokufakwa kwesakhiwo.

Imisebe ye-5.thermal

(1) i-coefficient yemisebe yebhodi lesifunda ephrintiwe;

(2) umehluko wezinga lokushisa phakathi kwebhodi lesifunda eliphrintiwe nendawo eseduze nokushisa kwabo;

Ukuhanjiswa kwe-hehe

(1) ukuhanjiswa kwemvelo kwemvelo;

(2) ukuphoqelelwa kwe-convection yokupholisa.

Ukuhlaziywa kwezici ezahlukahlukene kuyindlela ephumelelayo yokuxazulula ukukhuphuka kwamazinga okushisa ebhodini eliphrintiwe, imvamisa kumkhiqizo nohlelo lezi zinto zihlobene futhi zithembele, iningi lezici kufanele lihlaziywe ngokwesimo sangempela, kuphela isimo singabala ngokunembile noma silinganise ukukhuphuka kwezinga lokushisa nokusetshenziswa kwamandla kanye neminye imingcele.

Lokhu okungenhla kuhlelwe futhi kwanyatheliswa ngumhlinzeki we-aluminium substrate. Uma ungaqondi, sicela uxhumane nathi ku- " ymspcb.com ".
