摘要： Provided are a method for producing a thermoplastic liquid crystal polymer (TLCP) film having an improved thermo-adhesive property, a circuit board, and a method for producing the same. The production method of the TLCP film includes preparing a TLCP film as the adherend film and a TLCP film as the adhesive film;
examining each of the prepared TLCP films for a relative intensity calculated as a ratio in percentage of a sum of peak areas of C—O bond peak and COO bond peak based on the total area of C1s peaks in the XPS spectral profile so as to calculate a relative intensity X (%) as for the prepared adherend film and a relative intensity Y (%) as for the prepared adhesive film; and
controlling the TLCP film as the adhesive film to have a relative intensity Y by selection or activation treatment of the adhesive film so that the relative intensity X of the adherend film and the relative intensity Y of the controlled adhesive film satisfy the following formulae (1) and (2): 38
