Shorten development time of Functional Testing (FCT) in electronic manufacturing with smart instruments
(2021)Department of Automatic Control
- Abstract
- The development of electrical circuit boards is increasing and the time spent in the development stage can be quite long. The thesis has tried to shorten the time spent developing new electrical circuit boards, by first finding a common denominator for efficiency losses in the development process and then implementing an example solution. The problem identified was the lack of attention towards production testing early enough in the development process. The testing equipment often comes as an after though which delays the start of production. Since the product can not be mass produced before quality assurance can be done using testing equipment, this will lead to unnecessary time spent with products in development. Another problem...

- The development of electrical circuit boards is increasing and the time spent in the development stage can be quite long. The thesis has tried to shorten the time spent developing new electrical circuit boards, by first finding a common denominator for efficiency losses in the development process and then implementing an example solution. The problem identified was the lack of attention towards production testing early enough in the development process. The testing equipment often comes as an after though which delays the start of production. Since the product can not be mass produced before quality assurance can be done using testing equipment, this will lead to unnecessary time spent with products in development. Another problem addressed in the thesis is the expenses of acquiring a testing system. Today’s standard for testing systems is both big and expensive and a better solution would be beneficial.
To solve these problem the thesis purposes a solution using a micro controller connected to a small analog to digital converter. This solution is a lot cheaper compared to today’s standard and offer additional benefits described further in the thesis. The drawbacks of loss of performance compared to the more expensive equipment is also discussed.
To test said solution, three example implementations of the same smart instrument was done and evaluated. The implementation was then evaluated both on the possible time saved from using a smarter instrument compared to the same instrument without the smart API implementation and the performance of each of the three possible implementations.
The example implementation resulted in shorter development times and easier interaction with the instrument. It also fulfilled most of the requirements set on a smart instrument in the beginning of the thesis. Performance wise the implemented example instrument was good enough for most production testing situations and is therefore able to replace the more expensive versions for some applications. (Less)
