An inkjet ink composition having a binder including an aqueous dispersion of polymer particles, the polymer comprising as polymerized units from 3 to 20 wt. The tank circuits are integrated into the tuner chip through the combination of a phase-locked loop and multiple on-chip VCOs comprising narrow-tuning range varactors. The invention applies in particular to electronics cards for motor vehicles. The bottom insulating membrane is formed on and touches a side surface of the groove. The method operates on the basis of the principle of deflectometry with specific improvements.
