Tolerance Analysis‚ WCTA‚ and Statistical Tolerance Analysis‚ STA. The part is failing due to clearance between circuit card from male part of assembly and a metal contacting device of female part of assembly. We need use WCTA‚ STA to find suitable tolerance limit to eliminate so as to reduce probability of making parts outside of extreme tolerance zone. Assembly Overview The circuit card in male part of assembly which transmits the electrical current is inserted between metal contacting devices
