Aluminium PCB yowunikira zamphamvu za LED

Kugwiritsa ntchito ma PCB a Aluminium-Based PCB ndi osiyanasiyana, ndipo nthawi zambiri amagwiritsidwa ntchito m'mafakitale omwe amafunikira kukhathamiritsa kwamafuta. Zowunikira zowunikira za LED, makamaka, zimapindula ndi kuthekera kwapamwamba kochotsa kutentha kwa matabwawa, kuwonetsetsa kuti nthawi yayitali komanso kukhazikika kwamagetsi owunikira. Mu zamagetsi zamagalimoto, ma PCB Ochokera ku Aluminium amapeza ntchito muzowongolera mphamvu, mayunitsi owongolera magalimoto, ndi magawo ena omwe kuwongolera kutentha ndikofunikira.

Njira yopangira ma PCB a Aluminium-based PCBs imaphatikizapo kuyanika kagawo kakang'ono kakang'ono ka dielectric kamene kali ndi thermally conductive pazitsulo zachitsulo. Dielectric wosanjikiza uyu amapereka kutsekereza magetsi pamene amathandizira kusamutsa kutentha koyenera. Mafakitole a PCB apanga njira zapadera zopangira matabwawa bwino, kukwaniritsa kufunikira kwa mayankho owongolera matenthedwe m'mafakitale osiyanasiyana.

M'mafakitale a PCB Assembly (PCBA), ma PCB Opangidwa ndi Aluminium amapereka maziko olimba osonkhanitsira zinthu zomwe zimafunikira magwiridwe antchito apamwamba kwambiri. Kuwonongeka kothandiza kwa kutentha kumawonjezera kudalirika ndi moyo wautali wa misonkhano yamagetsi, kuwapangitsa kukhala oyenera malo ovuta.

Mwachidule, ma PCB Ochokera ku Aluminium amayimira njira yomwe amayang'ana pamapulogalamu omwe ali ndi zofunikira zowongolera kutentha. Kutentha kwawo kwapamwamba komanso kukhazikika kwawo kumawapangitsa kukhala osankhidwa bwino m'mafakitale omwe kupewa kutenthedwa kuli kofunika kwambiri, zomwe zimathandiza kuti zikhale zogwira mtima komanso zodalirika zamagetsi.
