Pcb, zita reChinese rakadhindwa redunhu bhodhi, inozivikanwa seye yakadhindwa wedunhu bhodhi, yakakosha zvemagetsi zvinhu, ndiko kutsigirwa kwemagetsi emagetsi, emagetsi zvigadzirwa ndiye anotakura emagetsi kubatana.Nekuti ivo vanoitwa neyemagetsi kudhinda tekinoroji, ivo vanodanwa Yong Ming Sheng aluminium substrate pcb inogadzira anotsanangura chikonzero chealuminium substrate pcb tembiricha inomuka.
Temperature simuka chinhu ongororo yeakadhindwa wedunhu bhodhi
Chikonzero chakanangana nekukwira kwekushisa kwePCB pane aluminium substrate ndiko kuvapo kwemagetsi ekushandisa michina mudunhu. Iko kushandiswa kwesimba kwemidziyo yemagetsi kunosiyana pamadhigiri akasiyana, uye kupisa kwekudziya kunosiyana nemagetsi ekushandisa.
Zvinoitika zviviri zvekupisa zvinokwira mumabhodhi akadhindwa:
(1) tembiricha yemuno inokwira kana hombe tembiricha inokwira;
(2) Pfupi-temu kana refu-tembiricha kumuka.
Kazhinji, simba rekushisa rePCB rinoongororwa kubva pane zvinotevera zvinhu:
1.Electrical simba Consumpti
(1) Ongorora kushandiswa kwesimba panzvimbo yeyuniti;
(2) Ongorora kugoverwa kwesimba pane pcb board.
2.Structure ye yakadhindwa redunhu bhodhi
(1) Kuyera kwemapuraneti edunhu akadhindwa;
(2) Yakadhindwa wedunhu bhodhi zvinhu.
3.Printed redunhu bhodhi yekuisa nzira
(1) Kuisa modhi (senge yekumisa yakatwasuka, kumisikidza kuisirwa);
(2) mamiriro ekuisa chisimbiso uye chinhambwe kubva kukiringi.
4.heat conduction
(1) isa radiator;
(2) kuitisa kweimwe kumisikidza zvikamu zvechikamu.
5.thermal nemwaranzi
(1) iyo radiation coefficient yeakadhindwa wedunhu bhodhi pamusoro;
(2) mutsauko wetembiricha pakati pebhodhi redunhu rakadhindwa nenzvimbo iri padyo netembiricha yavo;
6.heat convection
(1) zvakasikwa convection;
(2) Kumanikidzwa kutonhora convection.
Kuongororwa kwezvinhu zvakasiyana inzira inoshanda yekugadzirisa kukwirisa kwekukwira kwebhodhi rakadhindwa, kazhinji mune chigadzirwa uye system zvinhu izvi zvinowirirana uye zvinoenderana, zvizhinji zvezvinhu zvinofanirwa kuongororwa zvinoenderana nemamiriro ezvinhu chaiwo, chete kune chaiyo chaiyo mamiriro anogona kunyatsoverenga kana kufungidzira kusimuka kwetembiricha uye kushandiswa kwesimba uye mamwe ma parameter.
Izvo zviri pamusoro zvakarongeka uye zvakaburitswa nemutengesi wealuminium substrate. Kana iwe usinganzwisise, ndokumbira utibvunze ".
Kutsvaga kunoenderana nealuminium pcb:
