摘要： A squib includes an SCB chip connected to electrode pins so as to ignite by externally applied electric current, and a capacitor electrically connected to the electrode pins in parallel with a thin film resistor on the SCB chip. The capacitor is arranged above the header, and the SCB chip is directly mounted on the capacitor so that the thin film resistor on the SCB chip and the capacitor are electrically connected through electrodes provided on a substrate of the SCB chip, while the size of the SCB chip is smaller than that of the capacitor. In this way, the invention provides the squib which effectively eliminates surface unevenness when the capacitor is located, and enables the connection of the SCB chip and the capacitor to the electrode pins only by one reflow process, and further makes it possible to use an even smaller chip than those used in the prior art.
