An ink jet print head assembly (10) includes at least one elongate ink jet print head chip (20) that is the product of an integrated circuit fabrication technique. The assembly (10) also includes at least one corresponding ink jet print head chip carrier (14) that defines an elongate recess (18) having a pair of opposed side walls (28). The, or each, print head chip (20) is received in one respective recess (18). The, or each, ink jet print head chip (20) and said respective recess (18) are dimensioned so that a gap (26) is defined between the, or each, ink jet print head chip (20) and each side wall (28). Resiliently deformable material (22) is positioned in each gap to retain the, or each, print head chip (20) in position in said respective recess (18).

Ensemble de tête d'impression a jet d'encre (10) comprenant au moins une microplaquette de tête d'impression (20) produit suivant une technique de fabrication de circuit intégré. L'ensemble (10) comprend également au moins un support correspondant (14) de microplaquette de tête d'impression à jet d'encre définissant un évidement allongé (18) présentant une paire de parois latérales opposées (28). La microplaquette, ou chaque microplaquette de tête d'impression (20), est logée dans un évidement correspondant (18). La microplaquette, ou chaque microplaquette (20), et ledit évidement correspondant (18) sont dimensionnés de façon qu'un intervalle (26) soit défini entre la microplaquette ou chaque microplaquette (20) et chaque paroi latérale (28). Un matériau élastiquement déformable (22) est mis en place dans chaque intervalle de manière à maintenir en position la microplaquette ou chaque microplaquette de tête d'impression (20) dans ledit évidement correspondant (18).
