Abstract: An adhesive mixture (18) reworkably adheres electronic integrated circuit dies (14, 16) to hybrid microcircuit substrates (12), and includes a thermosetting epoxy resin. A thermoplastic resin additive allows the mixture to retain the high adhesive strength of the epoxy resin up to approximately 150 °C, or the upper limit of the operating and testing temperature range of the dies, and then soften sufficiently to enable defective dies to be removed at a temperature of preferably between 150 °C and 200 °C without damage to the substrate or adjacent dies.

Abstract: Un mélange adhésif (18) colle de manière amovible des matrices (14, 16) de circuits intégrés électroniques à des substrats de micro-circuits (12) et comprend une résine époxy thermodurcissable. Un additif de résine thermoplastique permet au mélange de maintenir la force d'adhérence élevée de la résine époxy jusqu'à approximativement 150 °C, ou la limite supérieure de la plage de températures de fonctionnement et de test des matrices, puis se ramollit suffisamment pour permettre de retirer les matrices défectueuses à une température comprise de préférence entre 150 °C et 200 °C, sans détériorer le substrat ou les matrices adjacentes.
