The 27" x 27" x 45" enclosure provides a stable test environment by blocking energy emitted by the ambient environment and blocking air currents generated by heating and air conditioning ducts. A motorized camera slide and controller precisely position the EL camera for Model Board Comparison and short circuit tests. A platform with adjustable PCB mounts enable repeatable positioning of board sizes up to 22" x 20".
The EL system detects and locates PCBA defects, such as short circuits and stressed components, which are difficult to identify using conventional test methods. EL can also be used to verify PCBA functionality. Advantages of EL over traditional functional testers include low cost and fast setup. No custom hardware is required and tests can usually be setup in less than an hour. EL is ideal when the high cost of a dedicated functional tester cannot be justified.
