Choziziritsira cha IGBT cha 45V 2000A 90KW cha Air Cooling cha Electroplating

Mu njira yopangira ma PCB, kuyika mkuwa wopanda magetsi ndi gawo lofunika kwambiri. Kumagwiritsidwa ntchito kwambiri m'njira ziwiri zotsatirazi. Chimodzi chikuyika pa laminate yopanda magetsi ndipo china chikuyika pa dzenje, chifukwa pansi pa zochitika ziwirizi, kuyika mkuwa sikungatheke kapena sikungatheke. Poyika pa laminate yopanda magetsi, mbale zoyika mkuwa zopanda magetsi zimagwiritsidwa ntchito kupanga mkuwa woonda pa substrate yopanda magetsi kuti substrate ikhale yoyendetsa magetsi kuti ipitirire kuyika magetsi. Poyika mkuwa wopanda magetsi, kuyika mkuwa wopanda magetsi kumagwiritsidwa ntchito kupanga makoma amkati a dzenje kuti alumikize ma circuits osindikizidwa m'magawo osiyanasiyana kapena ma pini a ma chips ophatikizidwa.

Mfundo yogwiritsira ntchito mkuwa wopanda magetsi ndikugwiritsa ntchito njira ya mankhwala pakati pa chochepetsera ndi mchere wa mkuwa mu yankho lamadzimadzi kuti ayoni wa mkuwa uchepe kukhala atomu ya mkuwa. Njirayi iyenera kukhala yopitilira kuti mkuwa wokwanira upange filimu ndikuphimba gawo lapansi.

 Mndandanda wa rectifier uwu ndi wapadera wopangidwira PCB Naked layer copper plating, umagwiritsa ntchito kukula kochepa kuti ukhale ndi malo oyika, mphamvu yotsika komanso yapamwamba imatha kuwongoleredwa ndi kusinthana kwamagetsi, kuziziritsa kwa mpweya kumagwiritsidwa ntchito ndi njira yodziyimira payokha yolumikizira mpweya, kubwezeretsanso kogwirizana komanso kusunga mphamvu, zinthuzi zimatsimikizira kulondola kwambiri, magwiridwe antchito okhazikika komanso kudalirika.
