100% inline control during laser drilling of microvias

Researchers report the development of a laser-based inline process control system to precisely drill microvias in printed circuit boards. This approach allows all microvias in a printed circuit board to be checked non-destructively during manufacturing without the need for follow-up quality tests.

Gentle defibrillation with optogenetics

Defibrillation used in an emergency is based on strong electrical impulses which, if successful, restore a regular heartbeat. A new approach aims at an electric shock energy that is 40 times weaker than before. This was developed with the help of optical modelling and optogenetic tests.

On-chip integration of optical isolators

Until now, optical isolators could not be realised as integrated components. An international team has now succeeded in rotating polarised light through an atomically thin semiconductor. Optical isolators as photonic integrated circuits could thus be made possible in the future.

Blackbird: growth strategy and new head of sales

Blackbird Robotersysteme, manufacturer of remote laser welding systems, has appointed a new sales manager and also created a new division for business field development, which the previous sales manager will be responsible for. The aim of the new divison is to expand remote laser welding into new areas of application.

New management at Bte Bedampfungstechnik

The company founder and managing director Reinhard Born retired from management on 1 April after more than 30 successful years. He will be succeeded by the former production manager and the head of electrical engineering.
