Yelo Rack System

The Yelo system range redefines the meaning of low cost test. Highly versatile, it can provide board testing, sub-assembly or final product testing. The range of test applications include in-circuit, functional and telecommunications. Functional testing can be at board or final product level.

A key feature is the ability to start small and be able to add test facilities as required.

Ideally suited to cellular manufacture, you can afford to dedicate Yelo systems to a product. A Yelo system can be used to complement an existing ATE providing, for example functional testing or a diagnostic work station.

The Yelo systems' inherent flexibility allows for future re-use for almost any new test requirements.

Extensive software tools simplify programming while low cost fixturing further reduces the cost of automatic test.

Yelo 7130 Key Features

The Yelo 7130 is the ideal test solution for volume production environments. It is a PC controlled test system utilising user-friendly software. The user can choose from a large range of measurement and stimulus cards which simply plug into the Yelo system. The facilities are routed, via a software controlled switching bus, to the front of the Yelo system and then to the unit under test. The system may be used with standard bed of nails fixtures or, if feasible, simple wiring harnesses.

Using bed of nails the fixture cost may be high if there are large numbers of boards to be tested. For this reason Mindready (NI) have developed a range of fixtures including low cost versions. Software tools virtually eliminate in-circuit programming and the F-Point programming environment allows simple creation and editing of functional tests. These effective tools reduce the skill level required to implement your test strategy.

The Yelo system is configured to suit your application which means that you only purchase the facilities required - this keeps cost to a minimum. This concept challenges the conventional philosophy where there is a high cost in the basic automatic test unit.
