3.1 General characteristics
• insulating layer in the sequential fabrication of multilayer circuits (SBU = sequential build-up
• suited for laser ablation with CO2, Nd-YAG and Eximer lasers
• finest structures can be represented without any problems
• very good adhesion of the subsequent metal plating (> 10 N/cm).
3.2 Product-specific characteristics
4.
4.1 General characteristics
• prevent the penetration of solder to the component side and the settling of flux residues in the
• ensure the sealing of via holes for vacuum adaption during in-circuit testing.
