Test and Handling Systems
We develop and construct for our customers complete test stations and test equipments for the development and production of electronic and, most of all, optoelectronic devices and products. Up to the specifications and capacity we develop manual- , semi- or fully - automatic test stations. For these equipments we develop and construct all parts of mechanics, electronics and software in our own company. Therewith we are able to provide optimized delivery times with technical faultless and financially optimized solutions.
At the following examples, the specific characteristics will be highlighted. With this widespread experiences and know how, we are able to provide solutions even for difficult tasks. Our project names are mentioned in brackets.
Automat for testing of laser modules
Automat for testing of laser modules
Automatic handler for testing of laser modules. The challenge of this test station is the exact positioning (±1µm) of the DUTS as
well as of an mirror that is temporarly inserted in the beam path.
System for contacting DIMM memory modules
This system is used for contacting of DIMM memory modules by special test heads in order to execute clock skew and jitter measurements.
Controller for LED taping
System for taping and sorting of LEDs. BAUER Engineering has develop the electronics and the realtime embedded software for this system.
Add-ons for wafer probing stations
We habe developped a series of add-ons for standardized equipment for wafer probing.
Sensor-Surveying (ALBA, IRIS, PREA and others)
The number of optoelectronic sensors is growing fast. We already have developed and constructed a wide range of special test stations for such kind of sensors. The pre-condition for such projects is a faithful co-operation with our customers, because of the necessary knowledge of design and functionality of the sensor to develop such test stations. Secrecy of such confidential information is absolutely compulsive to us.
Our developed and constructed equipments normally simulate the dedicated real conditions and the items and units to measure. Additionally there can be done some other measurements like surveying the beam properties, the EMI-stability or the attitude of temperature.
These measuring systems produce high demands to the mechanics, system safety, long termed stability and the device handling.
Surveying lasers and diodes, used for data transfer on single mode fibers up to 10Gb/s, causes high demands to the contacting system due to mechanical, electrical, optical and thermal coupling and connection. It was necessary for this project to develop specialized test contacting systems, granting reproducible measurements.
For optical distance measuring, there are used some power lasers with up to 100&nbps;W light power, which are able to send pulses of some few nanoseconds. For this reason it is necessary to switch driving current of about 50 A extremely fast and accurately. Additionally to the pulse generation it is necessary to have a light power to time ratio measurement device. Furthermore there are high demands to the measurement device on stability and the ability to calibrate.
MOST ® Transmitter and Receiver (OBIM)
The automotive interior environment is fitted with a growing number of infotainment devices like radio, phone, navigation device or CD player, with the increasing need of inter linking these devices. For this demand, the automotive and supplier industries developed the MOST®-Bus in closely co-operation. It is an optical ring bus with POFs (plastic optical fibers).
To test the send and receive devices, we develop and construct special components and equipments, checking the switching properties and behavior of these sending and receiving devices. The decisive point is to realize conversion from electrical in optical signals and vice versa, without any negative time critical interference.
A test station for characteristic lines of cord set semiconductor laser was upgraded for receptacle versions including a measurement device for light coupling with synchronous jiggling (rattling) the connector system. Additionally, the eye safety is tested on this equipment. To be independent of a laser's potentially existing squint angle, this measurement is solved with an infrared camera and dependent image processing.
These components, which are installed in a lot of infrared remote controller, are produced in a huge amount. BAUER Engineering develops and constructs semi and fully automatic test stations with high capacity, according for those devices. In these devices, control signals with adjustable light power and frequency are generated and the device's switching properties and behavior are determined.
