Details

Basic Information:

• Product Name: Wired Circuit Board Manufacturing Failure Analysis System

Product model: SRC AL309

Product Usage:

1. Detect the circuit open circuit and short circuit of the PCB , and the welding conditions of all parts, including missing components, wrong installation, parameter value deviation, continuous welding of solder joints, circuit board open and short circuit faults, and accurately inform the fault point.

2. In addition to the component test function, it also has TestJet , programmable power output, voltage and current acquisition, chip programming and other functional tests.

Features:

Core technology innovation ---- faster test speed, higher test accuracy and stability, and more flexible function expansion

1. The test core can be switched freely between single-core, dual-core, and quad-core, controlled by software, without changing the hardware, taking into account the large circuit board with multiple points and the small circuit board with multiple boards to achieve high-efficiency testing.

2. The four-pin eight-wire detection technology effectively eliminates the influence of probe contact resistance, and can stably detect resistance values ​​as small as 0.01 ohms, which can be resolved to 1 milliohm.

3. The dual-channel high-speed synchronous acquisition technology is applied, and the test speed and accuracy are improved at the same time.

4. The configuration of the program-controlled power supply is more flexible, which can meet the needs of different products under test for the program-controlled power supply.

Operation and use innovation ---- more convenient programming operation, more flexible method combination, more secure data management and control

1. The DIY programming mode for secondary development is convenient for users to independently develop the combined detection method of special devices.

2. The discharge point can be edited, and the combination of pre-test and post-test discharge, single test step discharge, and full board discharge methods can effectively protect the test system and the circuit board under test.

3. Signal source excitation has automatic setting and manual adjustment. The excitation signal of the signal source can be adjusted manually to meet special requirements.

4. Single-step automatic cycle test function, which is convenient for engineers to debug the board under test.

5. Using table format programming, it is convenient to create test steps and adjust the order of test steps.

6. Flexible panel testing, the same and different panels can be tested on one fixture at the same time, and the panel subroutines can be copied to realize fast programming.

7. The needle size setting can be freely defined, which is convenient for needle bed production.

8. Four-level authority management, data classification password protection, test program data management is more secure and reliable.

Structural design innovation ---- more reasonable structural design, more convenient fixture replacement, lower use and maintenance costs

1. The original layout of the channel plate saves the interface size and makes the needle bed production more economical and reasonable.

2. The original channel board plug-in method eliminates the need for maintenance from the left and right sides of the equipment, which reduces maintenance difficulty and machine footprint.

3. The needle bed pressing height can be configured by software, and it can be pressed twice during the test, which is compatible with high and low probes.

4. The width of the guide rail can be automatically adjusted according to the software configuration, reducing manual intervention and enhancing the accuracy of adjustment.

5. The original customized probe is directly connected to the fixture, the wire resistance interference is smaller, and the equipment performance is more stable.

6. Needle bed replacement is protected and will not damage the needle bed.

7. Innovative interface needle protection device to avoid interface needle contamination, and basically realize life-long maintenance-free interface needle.

8. Customized special interface needles can reduce the damage to the coating caused by the contact surface of the probes, and the contamination caused by the poor conduction. The interface needles are maintenance-free for life.

9. Automatically identify the needle bed, and do not press down when the upper and lower needle beds do not match, to prevent the needle bed from being crushed by the mismatch of the needle beds.

10. Each movement is monitored to enhance system security.

11. The original connection method between the equipment and the fixture can realize the rapid replacement of the fixture and greatly reduce the time of changing the line.

12. The fixture installation guide is added, and the handling of the fixture is more convenient and labor-saving, which lays the foundation for the automatic handling and installation of heavy fixtures.
