Chemistry Preserves Signal Strength for High Frequency Applications

摘要

High-speed, high-frequency boards experience signal loss from micro-roughening trace profiles. Beta tests have now proved that FlatBOND GT, MEC's marquis copper surface treatment from Uyemura, forms a chemical bond that is superior in strength to any mechanical bond, and preserves transmission signal integrity. FlatBOND is the only product of its type, and is predicted to become the gold standard for multilayer adhesion. FlatBOND provides a profile-free surface, and improves adhesion by 40% on low dielectric resins.
