Title
(EN) HEAD DEVICE PROVIDED WITH DRIVE ICS, TO WHICH PROTECTIVE COATING IS APPLIED, AND METHOD OF FORMING PROTECTIVE COATING
(FR) DISPOSITIF DE TETE COMPRENANT DES CIRCUITS IMPRIMES PILOTES SUR LESQUELS UN REVETEMENT DE PROTECTION A ETE APPLIQUE ET PROCEDE DE FORMATION DE CE REVETEMENT DE PROTECTION
Abstract
(EN)
A head device (10), in particular, a thermal print head, comprises an insulating substrate (11) having a first longitudinal edge portion (11a) and a second longitudinal edge portion (11b) opposite to the first longitudinal edge portion (11a), a work element (12) provided near the first longitudinal edge portion (11a) on the substrate, a plurality of drive ICs (13) formed in an array along the second longitudinal edge portion (11b) on the substrate for driving the work element (12), and a protective coating (17) of resin formed to cover the drive ICs (13) and having a terminal projection (17a) which is formed when the coating is formed. The terminal projection (17a) projects toward the second longitudinal edge portion (11b) on the substrate (11) and is disposed between adjacent two drive ICs (13).
(FR)
Cette invention concerne un dispositif de tête (10), et plus particulièrement une tête d'impression thermique, lequel dispositif comprend un substrat isolant (11) qui possède une première partie bord longitudinal (11a) ainsi qu'une seconde partie bord longitudinal (11b) opposée à la première (11a). Ce dispositif comprend également les éléments suivants: un élément de travail (12) situé sur le substrat à proximité de la première partie bord longitudinal (11a); plusieurs circuits imprimés pilotes (13), lesquels sont disposés en réseau sur le substrat le long de la seconde partie bord longitudinal (11b), et assurent le pilotage de l'élément de travail (12); et enfin, un revêtement de protection (17) se composant de résine, lequel recouvre les circuits imprimés pilotes (13) et possède une protubérance de connexion (17a) formée en même temps que lui. Cette protubérance de connexion (17a), qui est orientée en direction de la seconde partie bord longitudinal (11b) sur le substrat (11), est disposée entre deux circuits imprimés pilotes (13) adjacents.
