Abstract: At present, electronic products tend to be miniaturized, so the requirements for surface mount devices are getting higher and higher. The research on the EMC used for components is of great importance for improving the reliability of the patch and the quality of the final product. The o-cresol novolac epoxy resin (OCN) and phenolic resin (PN), the most commonly used for EMC, were used as the resin system, and eight various types of waxes were selected as the single variable design formula to synthesize EMC. The EMC/adhesives adhesion force was tested by the test method described, among which 5 kinds of waxes met the thrust criterion, and the influence law of wax types on EMC/adhesives adhesion force was analyzed. Combined with release test, the effects of various types of waxes in EMC production and use were analyzed. And the results showed that in the resin system, waxes 3, 4, 5 and 6 were the main waxes, and waxes 1, 7 and 8 were the auxiliary waxes. The problem of adhesives adherence is solved in the aspect of EMC, and it has certain significance to improve the operability of EMC production process.
