The ScanSpection Systems
Yestek currently offers three different AOI systems: ScanSpection AOI
Desktop, ScanSpection AOI In-Line and the X-Ray System.
ScanSpection AOI is a powerful machine vision inspection systems designed
specifically for fast, reliable and accurate inspection of printed circuit boards.
The In Line systems have the ability to handle boards up to 450mm x 457mm
in size. The System uses a high performance scanner or full colour inspection
with a scan area of 420mm x 300mm
Various zoom ratios are used to allow inspection at different magnifications.
ScanSpection AOI Desktop (off-line) large area AOI machine that can handle
board sizes up to 640mm x 500mm.
All YesTek AOI systems utilise the same software. The inspection program on
the Desktop & the In-Line Systems are inter-changeable.
Later in this document the name SCANSPECTION AOI will be used to refer to
all AOI system models unless otherwise mentioned.
The system control software is 32-bit Windows based. The software’s user
interface allows people with absolutely no programming experience to
intuitively create automated inspection sequences for complex PCBs. The
inspection sequence of the boards (also known as a board setup) can be
saved to a disk for later retrieval. This enables the user to modify and re-save
board setups under a different name and allows rapid creation of board setups
for similar boards.
The software interface uses object linking and embedding (known as OLE or
ActiveX) with Microsoft Excel for statistical data collection and analysis. A
CAD data interface is provided to allow easy board setup creation using the
board’s CAD data.
The software uses an open architecture allowing additional machine vision
algorithms to link in enhancing the inspection capability. These added features
come in the form of DLL (dynamic link library). This open architecture allows
the implementation of customised inspection functions in order to satisfy
special customer requirements.
The ODBC connectivity is implemented for inspection results and board
training data. ODBC allows data to be accessed by any ODBC capable
software across the network (Intranet or Internet).
The “Rework Data Server” (RDS) is a separate software product that utilises
web technology to distribute and present inspection data from the
SCANSPECTION AOI to a company’s intranet system with RDS every
computer on the LAN system can become a monitoring or a Rework station.
