| Isbarbardhigga Faraqa u dhexeeya heerarka IPC2 iyo IPC3 | ||
| Isbarbardhigga faraqa u dhexeeya heerarka IPC2 iyo IPC3 ee PCB-yada baabuurta: | ||
| Heerka IPC wuxuu muujinayaa heerka tayada nooc kasta oo ka mid ah looxa wareegga daabacan, qaar ka mid ah soosaarayaasha elektaroonigga ahna waxay leeyihiin oo keliya awoodda ay ku soo saari karaan alaabada heerka koowaad iyo labaad ee IPC. Waqtiga gaaban, waxaa laga yaabaa inaysan jirin farqi la dareemi karo, laakiin waqti ka dib, arrimaha tayada badeecadu way sii muuqdaan. Haddii badeecadaadu ay ka tirsan tahay heerka warshadaha oo aad diiradda saarto qiimaha muddada dheer ee badeecada, fadlan hubi inaad doorato heer sare. Heerarka tayada waxay ka kooban yihiin IPC1, IPC2, IPC3, GJB362C-2021, AS9100 | ||
