Flying probe testers flaunt high throughput

The latest A8a test system from atg Luther & Maelzer combines the flexibility of flying probe testers with high throughput. According to the company, the A8a offers remarkable cost advantages compared to fixture testers for small and medium batches and fully meets the requirements in its main application field.

The A8a ensures best productivity, most efficient operation and best test quality and accuracy, stated the company. It is equipped with eight test heads and four cameras for optical alignment. The A8a is able to test pad sizes down to 35um. Testing HDI products for smartphones, tablet and PC motherboards up to a test area of 18 x 12in on the A8a, it also eliminates limitations of test point density or fine-pitch contacts.

The A8a features embedded component test or a 4-wire Kelvin measurement with an accuracy of 卤0.025m鈩?.

The A8a is provided with a separate good and bad board stacker. The bad boards can be optionally labelled by a 2D-code, which indicates the reference between the boards and the corresponding fault file. This way handling failures by an operator are eliminated.

The A8a is prepared for lights out operation. With the feeder capacity of 390mm it is possible to test 650 boards with a thickness of 0.6mm at one time. This capacity guarantees an operator-free test over the whole night shift.

To fully meet the speed expectations the key feature of the A8a is a novel dual shuttle system, which reduces the product exchange time to less than 4s in automation mode. In combination with the fast test speed of up to 140 measurements/second the A8a will give customers a competitive test solution for batches up to 5000 boards. A typical cycle time of a 4-up smart phone board is about two minutes.
