Definitions

  • the present invention relates to an elastic collet for PCB mounting jig and a PCB jig assembly having the collet, more particularly, to an elastic collet for PCB mounting jig and a PCB jig assembly having the collet, which prevents bending and the soldering defect of a printed circuit board (PCB) in the process of mounting and soldering chips and parts on the PCB.
  • PCB printed circuit board
  • the PCB can be detached from the elastic collet with suitable force.
  • each through slots (30c) is longer than that of the large outer diameter portion (30a) of the collet to give the sufficient elasticity in case the collet is inserted in the pinhole (25) of the PCB. Since both distal ends of the large and small outer diameter portions of the elastic collet are chamfered with a predetermined angle, the elastic collet can be easily inserted into the pinhole (25) of the PCB (20) and through hole of the PCB jig (10).
  • the skilled person in the art can calculate the suitable frictional force needed for holding the PCB during transfer, and also can determine the suitable size of the outer diameter (D4) of the large outer diameter portion (30a) and the width (W) of the through slot of the elastic collet and the diameter (D5) of the pinhole. It is preferable that the length of the large outer diameter portion (30a) is shorter by about 0.2 to 0.3mm than the thickness of the PCB, not to protrude over the top surface of the PCB (20) when the elastic collet is inserted into the pinhole (25) of the PCB (20).
  • the small outer diameter portion of the elastic collet forms the interference fit with the small inner diameter portion of the through hole, since the outer diameters of the small outer diameter portion and the large outer diameter portion of the elastic collet are greater than the corresponding inner diameters of the through hole, respectively.
  • the length (L) of the interference fit can be adjusted appropriately for the elastic collet not to escape when the PCB is mounted with the elastic collet (30).
  • the length of the small outer diameter portion of the elastic collet should be shorter than the thickness of the PCB jig not to protrude below the PCB jig when being inserted.

Abstract

la présente invention concerne une douille élastique pour support de montage de carte de circuit imprimé et un ensemble support de montage doté d'une telle douille, l'objectif étant en particulier d'empêcher un phénomène de voilage et l'apparition de défauts de brasure sur une carte de circuit imprimé lors du montage et du soudage de microcircuits et de pièce sur la carte, et dont de simplifier le processus de montage en surface. Une carte de circuit imprimé dotée de la douille selon l'invention se caractérise en ce qu'elle comprend un ensemble de montage de type plaque qui présente sur sa surface supérieure une pluralité de trous traversants pour le montage d'une carte d'une certaine épaisseur et une pluralité d'éléments élastiques, combinés à la pluralité des trous traversants, qui servent à fixer amovible la carte de circuit imprimé sur la surface supérieure du support. Chacun des éléments élastiques est constitué par une douille élastique, présente une forme cylindrique creuse avec un diamètre intérieur et un diamètre extérieur, le diamètre extérieur comportant une partie de plus grand diamètre et une partie de diamètre plus faible, ce qui se traduit par un décrochement sur la surface extérieure de la douille élastique. Une pluralité de fentes traversantes d'une certaine longueur formées sur le pourtour de la douille élastique se déploient axialement à partir de l'extrémité de grand diamètre extérieur. Chacun des trous traversants du support présente une partie de grand diamètre intérieur et une partie de petit diamètre intérieur. Le diamètre extérieur de la partie de faible diamètre extérieur de la douille élastique est plus important que le diamètre intérieur de la partie de faible diamètre intérieur du trou traversant.
