1、 Function and function of bending testing machine:

This bending testing machine meets the requirements ofGJB548B-2005 Method 2004 Lead Wire Robustness Test: The bending test specified in 6.3.3 and 6.3.4 of Test Condition B1 can be set and adjusted for the bending position.

The experimental system consists of a control part, a rotating shaft, a fixed fixture, a lead fixture, and corresponding fixtures. The control system adopts PanasonicPLC control and touch screen display operation, simple and convenient operation, high intelligence, reliable performance and other humanized functions. The bending test uses a high-performance closed-loop stepper motor as the power source, making the rotation angle more accurate.

2、 Main technical parameters:

1) alternating currentsource220V±10%；

2) Bending test: bend one lead at a time;

3) Bending angle:Adjustable from 0 to 90.0 degrees, accuracy: ± 3 degrees;

4) Bending frequency:1 to 999999 times; Accuracy: ± 1 time (within 1-10 times);

5) Action cycle can be set (time for complete bending once)2-10 seconds/time, accuracy ± 3%.

6) toDIP/FP/CSOP/SOP/CQFP/MP/MQ/MBQ shell products have corresponding or universal fixtures.

7) When conducting flexible and semi flexible tests, the distance between the bending position and the sealing partAdjustable from 2mm to 5mm (with ruler scale). When bending double row leads, the bending point should be located as close as possible to the sealing area to 1mm

8) Bending a row of leads can also be done when the lead spacing is greater than1.5mm for single bending.

9) It is not allowed to use the pull lead method for bending, and various fixtures and tools must not cause any damage to the product beyond the lead bending test.

10) Rotating power source: closed-loop stepper motor+Gearbox;

11) The load-bearing capacity of the main shaft is greater than45N

12) Rotating fixture:3 sets, suitable for different product sizes

13) controller:PLC (original from Panasonic, Japan);

14) Display and operationStep by step touch screen;

15) Workstation:1 person;

16) The equipment is grounded, and the part where the sample is fixed has an anti-static grounding port that can be connected to an external anti-static ground wire.

17) All parts, components, and instruments of the equipment shall be measured using the International Standard of Units (SI)

18) All components of the equipment are brand new original products from the manufacturer, with advanced and mature technology, intuitive and easy operation, and convenient maintenance and repair. The electrical and mechanical performance must be safe and reliable, with corresponding protective measures

19) The equipment should have a sturdy support structure to ensure accuracy, reliability, and good safety during operation.

20) Equipment design and manufacturing should comply with national standards.

21) All parts, components, and instruments of the equipment shall be measured in accordance with national standards.

22) Overall dimensions:L<1000mm、W<1000mm、H<1000mm；

23) ambient temperature/Humidity: 10 ℃~35 ℃/10% RH~75% RH.
