Test Resource Utilization & Efficiency Report Suite
| The Test Resource
Utilization & Efficiency (TRUE) Report Suite from Derby Associates provides
electronics manufacturers with a quick and effective method to monitor and improve test
utilization on the shop floor or across the manufacturing supply chain. The TRUE report
suite improves engineering decision support, increasing test workcell productivity and
ultimately the "beat rate" of the production process.
ATE solutions, such as incircuit and functional test, play an important role in ensuring companies get quality products to their customer, while eliminating costly field failures. However, the cost of an effective test workcell can be high when factoring in test equipment, test engineering, program development and fixture costs. ATE costs can easily exceed millions of dollars, so there is a clear business need to maximize the return on test assets. If test resources are not managed effectively, electrical test can become a costly bottleneck on the shop floor, resulting in increased ATE capital, labor costs, cycle times and WIP. The TRUE report suite monitors real-time metrics so engineers can determine how effective test resources are being used and the root causes for poor utilization problems. TRUE reports can be added to Derby’s Shop Floor Quality or Web-PBQ quality management applications, making it possible to monitor incircuit or functional test utilization at local, remote and contract manufacturing sites. |

Test Utilization Reports:
Single Tester Utilization Report
This report calculates utilization as a percentage of the available hours in a day for an incircuit or functional tester over a selected date range. Utilization is displayed on a run chart that quickly indicates any abnormally low utilization periods that need further investigation. The report also includes a Tester Utilization Summary pie chart that compares testing and idle times. This report enables engineers to quickly check on the effectiveness a specific tester. Multiple Tester Utilization Report
This report calculates utilization as a percentage of the available hours in a day for multiple testers over a selected date range. This report enables the user to compare utilization across several testers at local or remote sites. Results are plotted on a run chart that shows daily utilization for each tester with the option of adding a running average. The report also includes a Tester Utilization Summary pie chart that compares total testing and idle times for the group of testers. Test Managers can quickly check on the effectiveness of their test resources regardless of where the equipment is in the supply chain.Testing Profile Report
This report analyzes the types of products that have been tested on a specific incircuit or functional tester and displays the information in a pie chart. The report provides a breakdown of the products being tested (i.e. % of total testing time by product) so the user can see if testing profile is effecting utilization. This report also provides data that can be used for test workcell planning or costing. Test Loop Count by Assembly Type Report
Reports the average number of tests required for a serialized board or unit to pass incircuit or functional test. The results are displayed as a bar diagram making it easy to detect excessive loop counts (e.g. >> 2) and highlights areas where tester utilization is poor and requires investigation. Test Loop Count Report
Lists all serialized boards or units that have exceeded a set test loop count limit. In verbose mode this report shows details on all test events and failures by serial number and enables the user to determine the cause for excessive test loop count. This report also enables engineers to detect rogue boards and pull them from the shop floor so they stop consuming test resources. Fixture Usage Count Report
Poor or worn fixtures, especially at incircuit test, can reduce tester utilization due to contact issues. This report takes the guesswork out of fixture maintenance by displaying the number of actuations perform by Fixture ID over a specified date range. Fixture usage is displayed on a bar chart in descending order. The user can set a Warning Limit and the color of the bars will change to red if the limit is exceeded, yellow if usage is within 10% and green if the usage is below 90% of the limit. The Fixture Usage Count report improves the maintenance process ensuring contact issues and "false calls" at the tester are minimized!Fixture Pin Defects Report
Some incircuit testers are capable of indicating which fixture probes are failing. This report displays which fixture pins are frequently failing. Engineers can use this data to target suspect fixtures pins that need to be replaced immediately or during the next scheduled maintenance. Feature & Benefits
Standard Utilization Reports – Improved decision-support and increase efficiency in the test workcell.
