Intelligent leadframe separation

In semiconductor industry lasers are used for leadframe cutting or hybrid cutting processes. The scanner-based cutting technology is fast and flexible enough to interact closely with preceding functional tests. With extremely small kerf widths even the tiniest lead structures can be processed.

Laser Cutting of leadframe and mold compound

Separation of certain highly integrated packagings, like QFN packages, requires Laser cutting of composite material – e.g. leadframe and mold compound. A combination of soft and hard material which makes mechanical sawing slow and prone to wear. In contrast, hybrid cutting with our lasers open up new vistas for clean and fast cutting of this type of composite materials.

Miniaturized memory cards (µSD) require cutting of irregular shapes. The half-cut technology, a combination of laser and mechanical saw, offers higher performance and less surface roughness than conventional methods.
