Electrolyte Bath Characterisation
Electroplating processes use an electrolyte as medium for depositing a metallic layer onto a substrate. The vast majority of the plating baths are water based, although more exotic solutions such as ionic liquids or organic solvent based electrolytes also exist.
The accuracy of results as obtained from Elsyca PlatingMaster computer simulations for predicting current density and layer thickness distributions over parts or substrates largely depends on the accuracy of the plating bath characteristics that are used as input data to the solver. Hence Elsyca has been constantly improving its Design of Experiment (DoE) in order to accurately capture the electrochemical characteristics of a given plating bath sample.
The laboratory experiments reveal information on:
- cathodic and anodic polarization behaviour of plating bath materials;
- cathodic plating efficiency of the component;
- dissolution rate of the anode materials;
- effect of agitation and temperature of plating bath on plating performance.
For some processes also roughness measurements, XRF alloy content determination or more enhanced surface analysis measurements (e.g. SEM) are performed.
