Abstract

The present invention provides a detecting device and a method thereof. The invention is used for detecting a package which comprises a plurality of tin balls. The detecting device comprises a detecting element and a switching element. The switching element is used for electrically connecting the package with the detecting element, and the switching element comprises a switching board, a bearing seat and a plurality of clamping pieces. The bearing seat is installed on the switching board and is provided with a notch. The package is provided in the notch. A plurality of clamping pieces are electrically connected on the switching board and penetrate the bearing seat corresponding with these tin balls and are projecting from the grooved inner base surface facing to these tin balls for clamping these tin balls movably in order to electrically connect these tin balls with the switching board. The detecting component detects the package through the switching board, these clamping pieces and these tin balls.

Description

【Technical field】 [0001] The present invention relates to a detection device and a detection method, and in particular to a detachable detection device and a detection method. 【Background technique】 [0002] The present detection method for trace breakage of the package mainly uses a time domain reflectometer (Time Domain Refletometry, TDR) to test the characteristic impedance of the internal transmission line. When the Ball Grid Array (BGA) package is to be tested for the traditional characteristic impedance, the package needs to be soldered to an adapter board first, and then the package is tested by the time domain reflectometer through the adapter board. Measure. However, the solder connection will not only cause damage to the package, but also the adapter board cannot be reused. Therefore, the traditional detection method is not only time-consuming but also consumes a lot of cost. [0003] In addition, in the traditional inspection method, inspection probes measure f...
