There is one other common packaging for integrated circuits and this is the PGA or Pin Grid Array. The BGA looks physically similar to a Pin Grid Array package. Both are one-sided; that is, only one face of the semi-conducting substrate is used for printing and mounting of circuit components. Moreover, both have an obvious grid-like pattern. However, the Pin Grid Array uses pins - thus, the name - whereas the BGA uses balls - as it has already been mentioned above. The pins (in the PGA) or the balls (in the BGA) are the materials through which electricity is conducted between the printed surface of the semiconductor board and the surface-mounted circuit components.http://www.capacitors.hk/

(1)Because the solid tantalum capacitor is of polar type, do not apply a reverse voltage to it.

(2)The figure on the below shows the relationship between current and reverse voltage.

Of much less concern, yet still important, especially in audio applications, is the micro phonic or piezoelectric effect. Barium titinate which is the base ceramic material for most dielectric systems will exhibit microphonic effects. It is not very difficult to take a Y5V capacitor and put a DC bias with a small signal 1kHz sine wave and get the capacitor to “sing”. Tantalum capacitors exhibit no microphonic effects. The experiment done by AVX involved the opposite phenomena whereby the part was shaken while under bias and the resulting generated voltage was measured. This was done for a series of 1µF devices and the results are shown in Fig below.
