More and more reliability and quality problems of electrical assemblies have to be solved due to the trend of miniaturization and the even higher level of integration. In some cases these failures can lead to catastrophic failure. The phenomenon of electrochemical migration is one of the most dangerous failure mechanism which usually results in short resistive circuits. In this paper electrochemical...
Laser manufacturing has several advantages to traditional processes. It is non-contact manufacturing, flexible and controllable. Because of these advantages laser drilled microvias are commonly used in the microelectronics industry. However possibilities of laser ablation can be exploited in several other fields as well. These are: window opening for TAB IC, bending windows, ditches for microfluidics...
