Imagine if you could immidiately see the measured effects of introducing a new lower-quality component into your products, even though the product is approved in final testing. Imagine if you are automatically given an early warning about potential quality problems in your high volume or high value products. SPC gives you the ability to closely monitor and quantify your product quality and production yield through all production steps.
Integrating FACTS in our existing device tracking/test result database system was straight forward and with the help of CIM very time efficient. Once the system was up running the need to maintain and update internal analysis and maintenance tools became obsolete. Fundamentally, the FACTS system gives us an easy way of getting a quick overview of yield & process data by applying an easy to use web-interface that can be accessed from nearly everywhere. The X-Y data support changed the way we analyze and view X-Y curve data essentially. The use of scheduled reports, which are automatically send out on a daily base, becomes very useful especially during product ramp-up. With the help of these reports, issues could be quickly identified and subsequently solved.
Statistical analysis and condition monitoring of test data
FACTS automatically imports production test results from automated testers. All test results are statistically analysed and stored in a central database. The database allows easy user access to the testdata by search & select criteria in a web-based user interface. While importing the test results, FACTS automatically monitors for any alarm conditions in the imported results (WECO rules) or in the monitored production process index values (Cpk).
As a Contract Manufacturer, FACTS simply means having tight control over the production batches for our different customers. We now have the right data very fast and up to deep level of detail, and so field failures have decreased because quality has improved as well as first pass yield.
In addition, implementing FACTS was a fast and easy task.
Closely monitor your production
Using the web-based user interface of FACTS, you easily get an overview of the quality and performance of your production. The user interface also provides direct and easy access to specific test result for selected products and production periods. Key functionality includes:
• Production net yield
• Production error pareto
• Test step mean value
• Test step standard deviation
• Handling and test time
• Production repair pareto
• Test step Cp values
• Test step Cpk values
Using FACTS has improved our time to solution greatly and also pro-activeness where trends can be applied to other product series. We see interest from teams which was not involved with product maturing before – a kind of gamification where we all compete against older designs and take pride in seeing yield improvement.
Your benefits from FACTS
FACTS provides you with indepth insight into your production test results. Using this insight provides your production processes with:
Early warnings about production irregularities
Fact based feedback to supply chain and production
Identify process improvement possibilities
Track and monitor process improvements
Error reports are automatically created in CIM Paperless Repair
Direct production quality measurement using Cpk and Cp values
Personalise your dashboard with drag-and-drop widgets
Create presentations, and info screens with the automated Kiosk Mode
