Abstract [sv]

Vid högvolymsproduktion av konsumentelektronik är testtid, mätnogrannhet och fabriksgolvsutrymme synonymt med kostnader. Detta har gjort att man på sektionen Test Engineering vid Ericsson Mobile Communications fabrik i Linköping tagit fram ett testkoncept, kallat Pelle-konceptet, där datorkraft och mätutrustning flyttas in i små utrymmessnåla testfixturer anpassade för både robotiserade produktionslinor och manuella. Det nya testkonceptet saknade på våren 1998 ett generellt mät- och stimulikort för mobiltelefoner vilket specificerades och konstruerades  under sommren och hösten 1998 av författaren och Stefan Lantz. I rapporten beskrivs arbetet med att specificera kortets funktionsblock samt detaljkonstruktion av de funktionsblock som författaren ansvarat för. Rapporten ger även en inblick i designarbetet och dess svårigheter för ett mät- och stimulikort med många olika funktionsblock på en mycket begränsad yta, samt de problem som uppstår i många projekt till följd av förändrade krav, missupfattningar, kommunikationsmissar och saknad dokumentation.

Abstract [en]

In high volume production of consumer electronics are test time, measurement accuracy, and factory floor space synonymous with costs. This has led to that the Test Engineering department at Ericsson Mobile Communication factory in Linköping has developed a new test concept, called the Pelle-concept, where computation power and measurement equipment is placed in compact test fixtures adapted for both automated and manual production lines. In the spring of 1998 the new test concept was lacking a printed circuit board for generalized measurement and stimuli of mobile phones, which was specified and designed during the summer and fall of 1998 by the author and Stefan Lantz. The report describes the specification of the functional blocks as well as the detailed design of the blocks designed by the author. The report also gives insight into the design work and its difficulties when designing a measurement and stimuli board with many different functional blocks in a very limited space, as well as problems common in many project resulting from changed requirements, misconceptions, communication glitches and missing documentation.
