Microcontroller Based Automated Testers & Systems...
Our Know-how & Experince
Microcontrollers has been used in the industry for many years now. We, in
Infinite Technology have learned to apply it in many application so that we
could offer our customers more options in terms of reduced complexity & lower
costs. It is well suited for applications whereby simple judgement and
processing is required.
Our controllers vary in many ways ranging from fully automated systems to
semi-automated systems to manually operated ones. By providing these options we
are able to cater to customers with small budgets as well as customers who want
more complex systems.
Our microcontroller systems are all user friendly to use and are highly robust &
Our sample works along with brief details as illustrated below.
Fully Loaded Printer Circuit Board(PCB) Tester
This test system was designed to test the functionality of a PCB. It is a
manually operated system whereby the operator is required to press the buttons
on the jig panel in-order to complete the test sequence. The microcontroller
system responds to each button press and switches on certain relays to trigger
the PCB. The LED are meant as results display.
The system shown below is a similar system to check the
functionality of the PCB but this system works automatically. Once the test is
started, it will check the functionality of the board automatically based on the
test procedure and display the test result on the LCD Display. Below
is the sample display for Pass & Fail conditions. This display will indicate
clearly which component or step is faulty so that proper countermeasure can be done.
Complete products testing
The system below is testing the functionality of the USB extension cables. A
microcontroller system is used to switch the wiring interconnections from the
1st cable to the 10th cable.
Each step is indicated by the 7
segment display on the tester panel. At the end of the process, the operator
will be able to isolate the faulty cable from the good ones. The mechanical
design is also designed for each identification and handling.
Sample of other projects
The system above is
designed to test the reliability of a DVD drive. The microcontroller
automatically, opens the DVD tray, checks the travel length of the tray using
photo-electric sensors. Then, the tray will be pulled out to the maximum length
and then pushed back in. Each cycle is counted and when the preset count limit
is acheived, the system stops the sequence. Any abnormal condition will be
detected by the system and the prosess will be halted.
