Abstract

A testing module for testing the strength of the welding area on a PCB is disclosed. The testing module has a plurality of first plates each provided with a plurality of pressing plates adjustably mounted thereon and a plurality of second plates each provided with a plurality of supporting plates securely mounted thereon. Each of the pressing plates are located at the center of two adjacent supporting plates, such that a plurality of PCBs are able to be tested for the strength of the welding area at a time.

Claims

1. A testing module for testing a welding area strength on a PCB, the testing module comprising:

a plurality of first plates (51) securely mounted in parallel with respect to each other and having a plurality of pressing plates (64) adjustably mounted thereto; and

a plurality of second plates (52) movably mounted in parallel with respect to the first plates (510 and having a plurality of supporting plates (61) securely mounted thereon;

wherein each of the pressing plates (64) are mounted at a location corresponding to a center position between a pair of adjacent supporting plates (61).

2. The testing module as claimed in claim 1 further having a base (40) provided with two posts (41) integrally extended outward therefrom and a top plate (42) slidably mounted between the two posts (41) and provided with a main shaft (43) securely extending out therefrom so as to have the plurality of first plates (51) securely mounted thereon and the plurality of second plates (52) movably mounted thereon.

3. The testing module as claimed in claim 2, wherein each of the second plate (52) have a plurality of slots (521) defined therein and the first plates (51) have a plurality through holes (511) defined to correspond to one of the slots (521).

4. The testing module as claimed in claim 3, wherein the pressing plates (64) have a cutout (641) defined therein and corresponded to one of the through holes (511) of the first plate (51) thereby allowing the pressing plates (64) to be adjustably mounted on the first plate (51).

5. The testing module as claimed in claim 4, including a retaining device (65) having a head (651), and a neck (652) integrally formed with the head (651) and a body (653) which is used to adjustably secure the pressing plates (64) to the first plate (51) by inserting the head (6510 and the neck (652) into the cutout (641) and extending the body (653) into one of the through holes (511) to be threadingly connected with a nut (514)

6. The testing module as claimed in claim 5, wherein two slits (512) are defined around each one of the through holes (511) and opposite to each other;

and

wherein two blind holes (643) are defined beside the cutout (641) and corresponding to the two slits (512) thereby allowing two pins (513) to be inserted through the slits (512) and into the blind holes (643) after the pressing plates (64) are secured in relation to the first plate 51.

7. The testing module as claimed in claim 3, wherein each of the slots (521) is T-shaped.

8. The testing module as claimed in claim 7, wherein a plurality of rectangular blocks (63) are provided to be slidably received in the T-shaped slot (521) to respectively correspond to one of the plurality of supporting plates (61).

9. The testing module as claimed in claim 8, wherein each of the supporting plates (61) have a through hole (611) defined therethrough and sa bolt (620 is provided to be threadingly inserted through the through hole (611) and into one of the rectangular blocks (63) to secure the supporting plate (61) with respect to the second plate (52).

10. The testing module as claimed in claim 2, wherein a secondary shaft (44) is provided to the base (40) and securely connected with a second plate (52) on a top thereof.
