Improve PCB Test Efficient
In this dynamic and competitive environment, successful PCB manufacturing must follow eight steps. Here we talk the sixth point in detail--- to improve the PCB test efficient.
The PCB test regime has been developed to address defects that occur as a result of production processes gradually or suddenly going out of control. Many other problems and defects can slip through manufacturing, only to be discovered at test or even later in the market. Along with material-related issues, process issues around screen printing, SMT mounting accuracy, and reflow can all lead to some degree of variation. The test process acts as a filter, ensuring that no defective products make it out of the factory. However, the nature of PCB test means that this can never be guaranteed.
A key factor in reducing defects through test and repair is the speed with which defects are detected and how quickly their prevalence across the factory is determined. Any delay between the defect occurring and being detected increases the likely number of defective units.
To significantly improve the test efficient, advanced software are used to capture test results. Such tools will immediately flag a problem and this ensures the correct routing of a defective unit to the repair station. At the same time, statistical analysis is performed to determine whether a more widespread problem has arisen.
This greatly reduces the time needed to find and process defects, limiting the scope of any quality failure. The increased timeliness and accuracy of quality reporting allows the manufacturer to change assembly operations swiftly, thereby reducing the extent of any defects.
