Fabrication method of solid electrolytic capacitor

A fabrication method of a solid electrolytic capacitor comprises the steps of fixing edges of lower surfaces of a plurality of valve metal foils at edges of upper surfaces of process strips, and allowing main body parts of the valve metal foils to partially extend outside the same sides of the process strips; dividing each valve metal foil into a positive electrode region and a negative electroderegion by isolation glue; forming a negative electrode on the negative electrode region to form a basic core; immersing an attachment mechanism in low-temperature silver paste to fabricate the negative electrode during the formation process of the negative electrode, wherein the attachment mechanism immersed in the low-temperature silver paste comprises a liquid height compensation machine, a knife edge positioning device, a liquid height detector, a first vibrator and a base, and the liquid sensor employs a ultrasonic liquid sensor; laminating the basic chips onto a lead frame layer by layeraccording to the designed
