Description

Test system

Technical Field

The embodiment of the utility model relates to the field of testing of electronic equipment, in particular to a testing system.

Background

At the factory end, a plurality of test items of the product need to be completed before shipment, the power cycle test is an important test link, the power cycle test takes up a very huge part of the test flow, a plurality of machines need to rely on manual operation and software assistance to reach the power cycle test link, and particularly in the S5 state, the test machine also needs to skip a plurality of tasks to start up through an external tool, the front operation is quite troublesome, and the welding signals are three power switch/5V/GND signals. In addition, many tests are also doped with AC/DC switched test items, which means that all test matrix increases coverage again, and therefore automated testing is imperative.

At present, the system is shut down by relying on an automatic test software named as mike II, then a power switch signal welding jumper of a tester is connected to a POC (as shown in the following figure), a USB A cable (containing 5V and GND signals of the system) is modified to be connected to the POC, and the POC wakes up the test system when detecting that the USB 5V signal disappears. Aiming at the welding of PWRswitch signals, because of different schemes and different executing difficulties, the number of the machine tools for welding jumper wires is almost greater than 300 per year at present, and the risk of burning exists during welding, and the misjudgment of an issue (the falling of bonding wires or the short circuit of a main board) is caused due to the instability of the jumper wires. In addition, the current notebook is lighter and thinner, many projects do not have USB-A port, and the traditional test method of PA can not meet the test of part of projects.

In the past, the AC/DC test was also powered on/off by an external relay, and the power on/off was not performed in a system-controlled manner, which resulted in that the system was not actually powered off and the relay was powered off AC, resulting in distortion of the test results.

The current test scheme has the following disadvantages:

1. the power on (power on) can be performed by manually skipping and connecting to another test fixture (POC) for the specific signal and the power operation.

2. There is a risk of burning out the machine when there is always a mistake in manual operation.

3. The port of the current test system cannot be suitable for the ultra-thin version of the USB-C port.

4. The latency per power cycle is long, lengthening the test time.

5. Because the relay is not an execution point by the system itself, the occurrence of the fact that the AC/DC timing point is not coincident with the expected timing point is possible.
