The Static Intercept Difference
Static Intercept was developed by Bell Labs to solve the problems that industry was experiencing with ESD and corrosion. Corrosion is one the largest causes of latent or field defects. Bell Labs developed a revolutionary new technology that combine the state of the art ESD protection with unequaled corrosion protection. No other ESD product on the market can prevent corrosion, in fact many current ESD packaging systems help promote corrosion - the silent killer of electronics.
