Dongosolo lamagetsi atatu, lomwe ndi batri yamagetsi, chowongolera ma mota ndi mota, ndiye gawo lalikulu lomwe limatsimikizira momwe magalimoto amayendera mphamvu zatsopano. Chigawo chapakati cha gawo loyendetsa galimoto ndi IGBT (Insulated Gate Bipolar Transistor). Monga "CPU" mumakampani opanga zamagetsi, IGBT imadziwika padziko lonse lapansi ngati chinthu choyimira kwambiri pakusintha kwamagetsi. Tchipisi tambiri za IGBT zimaphatikizidwa ndikuphatikizidwa pamodzi kuti apange gawo la IGBT, lomwe lili ndi mphamvu zambiri komanso mphamvu zowononga kutentha. Zimagwira ntchito yofunika kwambiri komanso chikoka pamagalimoto amagetsi atsopano.
Carman Haas atha kupereka njira imodzi yokha yowotcherera gawo la IGBT. Dongosolo lawotcherera lili ndi CHIKWANGWANI laser, sikana kuwotcherera mutu, laser controller, control cabinet, madzi kuzirala unit ndi zigawo zina wothandiza. Laser imalowetsedwa kumutu wowotcherera kudzera panjira yolumikizira CHIKWANGWANI, kenako imayatsidwa ndi zinthu zomwe zimawotcherera. Pangani kutentha kwakukulu kwambiri kuti mukwaniritse kuwotcherera kwa ma elekitirodi owongolera a IGBT. Zida zazikulu zogwirira ntchito ndi mkuwa, siliva-wokutidwa ndi mkuwa, aloyi ya aluminiyamu kapena chitsulo chosapanga dzimbiri, chokhala ndi makulidwe a 0.5-2.0mm.
1, Ndi kusintha kuwala njira chiŵerengero ndi magawo ndondomeko, woonda mkuwa mipiringidzo akhoza welded popanda sipatsira (chapamwamba mkuwa pepala <1mm);
2, Okonzeka ndi mphamvu polojekiti gawo kuwunika laser linanena bungwe bata mu nthawi yeniyeni;
3, Okonzeka ndi LWM/WDD dongosolo kuwunika kuwotcherera khalidwe aliyense kuwotcherera msoko Intaneti kupewa mtanda zilema chifukwa cha zolakwika;
4, kuwotcherera malowedwe ndi khola ndi mkulu, ndi kusinthasintha kwa malowedwe <± 0.1mm;
Kugwiritsa ntchito kuwotcherera mkuwa kwa IGBT (2+4mm / 3+3mm).
