QUAD (QUality ADvisor) is a software suite built around a centralized database for providing traceability of any PCB / Systems electronic production data. It offers a powerful support for PCB fault diagnosis and collects all data regarding PCB repair to share experience between QUAD users. It provides access to detailed information in real-time that can be presented clearly and precisely using advanced reporting.
The strategic benefits that the manufacture can expect include:
QUAD (QUality ADvisor) is a flexible modular Quality Management system built around a centralized and open architecture database, providing traceability for any PCB electronic production data. QUAD covers all quality aspects of PCB assembly, sub-assembly and system build, allowing you to manage the quality data flow from product realization to product retirement. It has been designed to be used either standalone or to be easily integrated into any existing production environment.
The software offers powerful support for PCB fault diagnosis and provides access to detailed information in real-time that can be presented clearly and precisely using advanced reporting. This allows users to analyze real-time information, in order to diagnose and resolve process problems at the earliest opportunity to improve yield, quality and productivity, which will ultimately result in lowering cost.
QUAD comprises of 3 main modules:
QuadRecorder, part of tester interface, is a generic data logger that allows automatic access to all test and diagnostic results generated by Automatic Test Equipment.
QuadStation, part of repair, analyses the data presented to the repair and diagnostic station, to allow the operator to quickly fix the detected fault and graphically input repair data into the QUAD database.
QuadReports produces advanced quality management information and reports in real-time and can be delivered by e-mail or provide automatically a web site.
QuadRecorder with the use of a template file, will automatically collect data from sources on your shop floor. Once the data is collected, the tools can be applied for paperless inspection, test, diagnosis and repair. We can interface with the ERP database to collect further information negating the need to duplicate effort.
QuadStation provides powerful diagnostic assistance tools to aid the repair and troubleshoot of defect boards.
QuadTest allows the operator to graphically input manual operations or visual inspection results into the QUAD database.
QuadFeederSafe can be added for production component management, feeder management, loading management and component traceability.
QuadWIP can be added for board or batch location and timing checks.
QuadReports and QuadWebReports can be added for production and publication of real time reports and alarms.
Quad-DPMO will extract the true Defect Per Million Opportunities from the traceability database, built from the production line. Enables to use the real DPMO to drive and improve future test coverage estimation from Schematic or layout.
QuadRecorder Tester Interface
QuadRecorder is a generic data logger that captures data from any test system and assembly machines connected to the database host. The main features are:
Intelligent parsing of fault tickets or datalog files for different systems (AOI, AXI, ICT, Boundary-Scan, Flying probe and other dedicated machines for assembly).
Customizable data input scenarios i.e. RETEST, known false defect …etc.
ATML, XML and Generic parsers are available and are free of charge.
Original fault ticket filing management.
Measures collection for SPC (Cp, Cpk…)
QuadStation provides the user with a complete traceability and history of the product. During the diagnostic step, the operator has a set of powerful tools to help him in the search for a defect. When it is found, a simple click is enough to capitalize this experience and thus share it among all QUAD users.
Test result retrieval.
Diagnostic assistance.
Recording of quality data.
A derived version of the QuadStation named QuadTest allows the operator to graphically input a manual operation result into the QUAD database when no automatic test is performed.
QuadStation Repair Station Software
The Graphical User Interface (GUI) for both defect entry and Paperless Repair, uses the powerful viewing features of the QuadView® schematic and layout viewer from ASTER Technologies.
QuadView CAD Viewer for schematics and layout
Using the Paperless Repair screen, the user can select the fault to be repaired and allocate the appropriate repair code.
QuadStation provides powerful diagnostic assistance tools such as:
Total interactivity between electrical schematic view, layout view, netlist navigator, the tester fault ticket, the defect data grid and the defects advisor bar graph.
Defects advisor facility to allow the operator to have access to statistical fault repartition data that has been previously recorded for the same type of product under repair. Repair data is updated in real time for immediate experience sharing.
The ‘WEB Navigator’ style interface in the fault ticket allows users to interactively view the fault location on the schematic and layout viewers along with statistical representation of repair activity.
The short-circuit assistant
The Sherlock Algorithm guides the operator in the Functional test diagnostics.
Visualization of the physical layout allows repair technicians to quickly identify components, pins and PCB tracks, resulting in significantly reduced diagnosis and repair time.
Visualisation of nails information at the electrical schematic level.
Fully automated graphical fault code collection.
Panel test management with advanced visualisation.
Historical reporting of all the repair activities that have been either performed on a specific PCB or on a specific repair station.
QuadStation offers a graphic environment for the repair of the panel. When the tested panel failed, then a view of the panel is displayed on the screen with a red area over the failed boards and a green square over the good boards. This view can be displayed on the Top or on the bottom side. Each red area is linked to a tab corresponding to each test result of failed board on the panel. This allows operators to find quickly the failed board and avoids errors of repair.
QuadStation Panel-management
QuadReports allows interactive or automatic traceability and quality report generation using the de-facto standard Crystal Reports™ tool. These textual and graphical reports are fully customizable and can exported in PDF or Excel format to be easily distributed via email. The QuadReports for the Web is also available for investigation, presentation of quality report and repair data, anytime and anywhere.
This module also supports user programmable alarm generation to indicate critical changes to the manufacturing process that require immediate remedial action to be taken.
QuadReports Defects Alert
The reports are defined by the user with a number of parameters such as the start date, the end date, the station name … They can extract:
Defects and repairs (Yield, FPY, Pareto of defects, Workflow, DPMO …)
Measures in the test program (Cp, Cpk, Mean, repeatability …)
Some examples of a typical advanced reports are detailed below:
QuadReports examples
Reports can be created in any user specified format i.e. bar, column, pie and Pareto charts as shown above for visualizing any type of data. It is particularly useful for Statistical Process Control (Cp, Cpk) analysis, for representing First Pass Yield (FPY) and DPMO information etc.
QuadReports Webapplication Charts
All reports can be produced in HTML format for remote access through an internet connection to a centralised web server and downloaded to any client application running on a PC, tablet or smartphone. This particularly useful when you are working remotely to the manufacturing facility and it is necessary to obtain real-time data at anytime and anywhere.
Ease of Use Flexible modular software application that is easily integrated into an existing quality system organization, or used as a stand alone application.
Based on Industry Standards Interfaces with industry standard database environments, such as Oracle, MS-SQL, Access .. etc.
