Abstract
An active liquid applicator is provided which is designed to coat a surface of an electronic parts such as an oxygen sensor with an active liquid for forming an electrode. The liquid applicator includes a nozzle head and a nozzle tube. The nozzle tube has disposed therein a pearmable member which produces capillary attraction of an active liquid thereinto and feed it to the nozzle head, thereby enabling formation of a thin active film on the electronic part which has the thickness controllable with high accuracy.
Claims6
An active liquid applicator comprising:
- a dispensor storing therein an active liquid;
- a nozzle tube connected to said dispenser;
- a nozzle head provided on an end of said nozzle tube for applying the active liquid on a surface of an electronic part for forming an electrode;
- a permeable member disposed within said nozzle tube, having a length with first and a second end, the first end being connected to said nozzle head, the second end being exposed to the active liquid, said permeable member working to feed the active liquid from said dispenser to said nozzle head;
- a first mechanism working to make a contact between said nozzle head and the surface of the electronic part;
- and
- a second mechanism working to move said nozzle head and the electronic part relative to each other while keeping the contact therebetween to coat a preselected portion of the surface of the electronic part with the active liquid.
