Alex Wilkinson of W Technology, 1 Chamberlain Place, Kidlington, Oxford, UK, became very interested in the eC-test-mate after seeing it demonstrated on the Eurocircuits stand at a recent trade show. W Technology develops and designs circuits, PCBs and firmware for a wide variety of products and product areas. Following on from the design phase, the prototyping and production stages which W Technology can also take care of usually require some degree of testing. As a result they are always looking for smart ways to speed up and automate testing while reducing the amount of manual intervention. The eC-test-mate looked particularly ideal for a product W Technology builds for John Wainwright Systems – an access control specialist. The board in question has an RS485 interface which could easily be used as a test interface into the board, and lots of relay controlled outputs, all of which need to be tested. It also has numerous inputs and outputs for inter-system connections, entry card readers, door sensors etc. For this board to be delivered to the client and meet W Technology”s high standards, all of these interfaces need to be tested.
That”s where the eC-test-mate looks ideal. On the surface, it looks like it can provide multiple automated test functions and measurements and take out the majority of the manual testing currently required. The fact that it runs a scripted test process means it should be easily adaptable to any future changes made to the board design or functionality, which is inevitable.
So W Technology took delivery of an eC-test-mate system complete with the Eurocircuits eC-test-mate Demo Board.
The PC software is freely available from www.eurocircuits.com/test. Version 188.8.131.52 was available at the time of writing. Installing the software is easy and only takes a matter of seconds. The demo board test scripts are available from the same location and come in a .zip format. The first thing you naturally do with a .zip file is to open it up and extract all the files, but in fact this is not necessary as the eC-test-mate software works with the zip file itself, saving you having to open it and create a folder for all the files it contains.
Open the eC-test-mate program and click the large blue “PCB manager button”. Then click the “Import” icon at the bottom left of the screen:
Make sure the required test head is plugged in to the PC (In this case, test head 1, green), click on the newly imported board and then the green tick at the bottom, “Activate”.
