Embodiment Construction

[0027] 1. Layout design

[0028] To draw the design curve of the thick film resistor is to make the change curve of the length of the thick film resistor and the resistance value of the thick film resistor. In order to explore the relationship between the length of the thick film resistor and the resistance value of the thick film resistor, the actual product must be prepared. By measuring the resistance value of the thick film resistor of the actual product, the length of the thick film resistor and the resistance value of the thick film resistor can be obtained. change curve. Therefore, in order to prepare an actual product, it is necessary to design a thick film resistor terminal effect curve to make a layout. The specific layout design method is as follows:

Abstract

The invention relates to a method for manufacturing resistor end effect curves of a thick-film integrated circuit, and the method comprises the following steps: a) printing 28 conduction bands B on a film-forming baseplate respectively, wherein spacing intervals A between every two adjacent conduction bands are 15mil, 20mil, 25 mil,..., 70mil, 75mil and 80mil, 14 kinds in total, respectively; b) printing a thick-film resistor r1-r14 with the resistor width of 40mil on the film-forming baseplate respectively; c) using a multimeter to measure the resistance of the thick-film resistor in the film-forming baseplate, recording the measured resistance in an Excel sheet, and getting N which is equal to R/Ri*(W/L) according to the formula that R=Ri*N*(L/W); and d) utilizing the drawing function of Excel to draw a resistor end effect curve map against the different resistor widths respectively. The invention has the following advantages: solving the resistor design error problem caused by the situation that a thick-film slurry manufacturer only provides a single conductor end resistor design curve, improving the design technical level of a thick-film circuit layout, ensuring the resistanceconsistency of the thick-film resistor during the practical processing and enabling the deviation among the resistances of the resistors with the same resistance to be less than 5% when lapping different conductor ends.
