Abstract

A printed circuit board testing device for performing an electrical test on a printed circuit board having test contacts includes a test platform, a positioning unit, an electrical connection unit, and a detecting unit. The positioning unit is disposed on the test platform and adapted to receive the printed circuit board. The electrical connection unit is disposed on the test platform and has a plurality of preset electrical functions. The electrical test specific to the test contacts is performed on the test contacts by the detecting unit connected to the test contacts and the electrical connection unit and based on the preset electrical functions.

Claims

1. A printed circuit board testing device for performing an electrical test on a printed circuit board having test contacts, comprising:

a test platform;

a positioning unit having a receiving recess, disposed on the test platform, and adapted to receive the printed circuit board through the receiving recess;

an electrical connection unit disposed at the test platform and having a plurality of ports, wherein the ports have preset electrical functions, respectively; and

a detecting unit having two testing ends, one contactable with the test contacts, another connectable to at least one of the ports according to the electrical test to be performed on the test contacts, such that the electrical test is performed on the test contacts with regard to the preset electrical functions.

2. The printed circuit board testing device of claim 1, further comprising a control unit having a programmable electrical input/output interface and connected to the electrical connection unit for controlling the preset electrical functions of the ports through the programmable electrical input/output interface.

3. The printed circuit board testing device of claim 2, wherein the control unit is installed with Laboratory Virtual Instrument Engineering Workbench.

4. The printed circuit board testing device of claim 2, wherein the preset electrical functions include at least one of output voltage level output, ground level output, analog power supply output, standby analog power supply output, universal serial bus (USB) input/output, RS-232 serial communication interface input/output, trigger signal output, detection input, microphone input, data input, speaker output, and earpiece input.

5. The printed circuit board testing device of claim 1, wherein the detecting unit is one of a single conductive wire and a bus wire.

6. The printed circuit board testing device of claim 1, wherein the ports comprise 80 pins.

7. The printed circuit board testing device of claim 1, wherein the positioning unit further comprises at least a through hole disposed at the receiving recess and corresponding in position to the test contacts.

8. The printed circuit board testing device of claim 7, further comprising a dial module having a plate and needles and being selectively disposed between the test platform and the positioning unit, the needles corresponding in position to the at least a through hole and penetrating the at least a through hole to come into contact with the test contacts.
