Liquid Coating

Fungus-Resistant Topcoat

We are using a mil spec polyurethane topcoat, MIL-PRF-85285, on an electronics housing, and I am trying to find a reference indicating that this topcoat is fungus-resistant.

Mechanical Finishing

Investigation of Tin Whisker Formation

Immersion tin and lead-free hot air solder leveling (HASL) coatings based on SnCu or SnAgCu alloys are widely used as surface finish materials for printed circuit boards (PCB). These coatings prevent the underlying copper from corrosion and preserve its solderability during lead-free assembly processes and for a long storage life of PCBs.

Validation of New Generation Tooling Concept for Electroplating of Copper on Printed Circuit Boards

A dynamically software controlled electroplating tooling concept has been developed to compensate the pattern dependence of the deposited layer thickness on different substrates. In this paper a validation of this new tooling concept on industry relevant printed circuit boards is presented. Simulations are compared with experimental results as obtained in a prototype electroplating cell. A quantitative improvement of the plating thickness uniformity between a standard electroplating cell and the advanced tooling approach is given. The influence of the conductivity of the electrolyte on the deposit distribution is studied and indicates a way to obtain a significant improvement in uniformity.
