A component for a printhead module (12) includes a printhead chip (18) and a flexible printed circuit board (PCB, 54) on which the chip (18) is mounted. A carrier having fluid communication channels (72) defined therein supplies ink to the chip (18). The PCB (54) is bonded to the carrier in a liquid tight manner so that the PCB (54) forms a wall of an ink supply chamber (30) of the printhead module (12).

Un élément destiné à un module (12) de tête d'impression comprend une puce (18) de tête d'impression et une carte à circuit imprimé souple (PCB, 54) sur laquelle est montée la puce (18). Un support comportant des passages (72) de communication pour le fluide définis dans ce dernier envoie de l'encre à la puce (18). La PCB (54) est soudée au support de manière étanche au liquide de sorte que la PCB (54) forme une paroi d'une chambre (30) d'alimentation en encre du module (12) de tête d'impression.
