In case of the integration of an actuator or button by the customer, please consult us if use of plasticizer agent for button raw material (risk of chemical migration). Our actuator contains carbon particles and is electrical conductive. In consequence, customer actuator must be electric insulating raw material. Due to the cover raw material plating, small tin balls can appear after the reflow soldering process. These small tin balls are located near all cutting areas.
