WebIonic contamination testing successfully removes most non-ionic contaminants in prior to the conformal coating process. Ionic testing is an efficient, inexpensive method of ensuring the level of cleanliness on a PCB and can typically be applied in just 1 day. Ionic Contamination Testing Across Multiple Industries Webcomes to spray drying Li-ion battery material. Because individual cathode and anode powders vary widely in composition and characteristics, GEA’s powder engineers tailor each solution to the specific downstream components. Comprehensive pilot plant testing enables us to select and optimize the process design, so that you can produce powders
