Abstract:
1. A method for manufacturing a dielectric ceramic layer and an internal polar layer for an MLCC and the manufacturing steps are as follows: a) forming a first dielectric ceramic layer by initially setting a vacuum chamber pressure at 5×10 b) forming a first internal polar layer by setting the vacuum chamber pressure at 5×10 c) applying a mask etching treatment to draw a first internal polar circuit on the first internal polar layer, exposing a first polar circuit track using a micro image photoresistor and employing an etching process to finish the first internal polar circuit; d) forming a first insulation dielectric ceramic layer on the first internal polar layer by setting the vacuum chamber pressure at 5×10 e) forming a second internal polar layer by setting the vacuum chamber pressure at 5×10 f) applying the mask etching treatment to draw a second internal polar circuit on the second internal polar layer, exposing a second polar circuit track using the micro image photoresistor and employing the etching process to finish the second internal polar circuit; g) forming a second insulation dielectric ceramic layer on the second internal polar layer by setting the vacuum chamber pressure at 5×10 h) finishing the MLCC by performing a final treatment including cutting, drying, silver sealing end and performance test.
