The A8a test system provides the flexibility of flying probe testers while delivering high throughput testing for bare board printed circuit boards (PCBs). The target market for the A8a is the electrical test of tablet and PC motherboards and high density interconnect (HDI) products for smart phones.
The A8a is designed for high productivity, reliability and test accuracy. To achieve high throughput the key feature of the A8a is a new dual shuttle system, which reduces the product exchange time to zero seconds 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 2 minutes.
To ensure accuracy the A8a is equipped with eight test heads and four cameras for optical alignment. The A8a is able to test pad sizes down to 35 micron and is capable of testing HDI products for smart phones or tablet and PC motherboards up to a test area of 18.9” x 12.2”. The A8a eliminates limitations due to test point density or fine-pitch contacts and also features embedded component test or a 4-wire Kelvin measurement capability with an accuracy of +/- 0,025 mâ„¦.
The exchangeable clamping and tension bars can handle thin boards, too.
