Embodiment Construction

[0025] The present invention is further described below by embodiment in conjunction with accompanying drawing:

[0026] Fingerprint identification module components, see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 . Including cover 1, induction sheet 2, collection prism 3, base 4, first circuit board 5, second circuit board 6, imaging device 7, light source 8, cover 1, induction sheet 2, base 4 and second circuit board 6 enclosed space.

[0027] There is a positioning step 51 on the first circuit board 5, and a positioning groove 41 cooperating with the positioning step 51 is arranged in the circuit board mounting cavity C of the base 4. The length of the first circuit board 5 is slightly longer than the bottom length of the base 4, which is convenient for sensing the chip. 2 Welding with the first circuit board 5, when the first circuit board 5 is installed in the circuit board installation cavity C of the base 4, the positioning st...
