Curved legs and a broken pin this image of integrated circuits, especially those very expensive – which elektronikom spends sleep. A damaged pin may not always be correct. It is easy to grab the item, and the chip (despite the rest, more than 30 healthy legs) will fit only in the trash. If it's an expensive microcontroller, a programmable circuit, or an accurate analog-to-digital Converter, such a case can be a serious problem in the implementation of the system. Fortunately, such incidents can be counteracted by using coasters under the chip. They facilitate the mounting of the chips, or also quickly and easily be slightly changed, without the risk of damage to the circuit Board with repeated soldering, or damage the chip by pulling his pin.
