In miniaturised technology, small particles of contamination can cause a calamity.
Technical cleanliness is the latest quality feature in screw fastening assembly
In miniaturised technology, the elimination of tiny particles while fastening screws during the assembly process is a new quality feature. If when a circuit board is being assembled, a microscopic piece of steel – invisible to the naked eye – escapes, a disaster is sure to happen. A short-circuit will occur if the tiny chip accidentally connects two of the conducting tracks. As assembly parts become ever smaller even microscopic particles, measuring a mere 500, 200, or just 100μ, can cause a malfunction. Which is why what has become known in joining technology as “technical cleanliness” is of increasing importance in the design and building of screw fastening assembly systems (…)
