Many electrical components such as capacitors, resistors, and inductors have only two leads where some integrated circuits (ICs) can have several hundred leads to more than a thousand for the largest BGA devices.
Mange elektriske komponenter såsom kondensatorer, resistorer og spoler har kun to tilledninger hvorimod integrerede kredsløb (IC) kan have adskillige hundreder tilledninger til mere end tusind for de største BGA enheder.
