Definitions

  • the present invention relates to electroplating -equipment for the production of printed circuit boards (PCB or PWB), the substrata to be plated being passed horizontally through rollers that have absorbed the plating solution in a wet bed unit, said substrata being taken up laterally during . transport by gripping devices . that comprise pincer-like means provided with a cathode contact insulated from the plating solution or, to state it more precisely, the invention relates to a gripping device having clamping pincers with a double cathode contact on both sides of a dielectric substratum to be subsequently electroplated.
  • PCB or PWB printed circuit boards
  • This method is known as direct metallization of the holes by chemical means; it can be done by using a conductive polymer, or graphite or other similar materials, even though these possess a specific resistance superior to that of the copper used in the plating process.
  • Direct metallization of the holes leads to imperfect electrical conductivity due both to the materials used arid to the layer applied being very thin. On account of this, and also because the gripping device ensures electrical contact on one side only, it generally happens that current is not evenly distributed on both faces of the substratum which therefore leads to uneven distribution of the plating material.
  • Figure 1 shows the position of the device on the chain conveyor-belt mechanism for transporting the substratum ( Figures 1, 2, 3 and 4 correspond, in the same order, to Figures 17, 7, 1OA and 1OC of the citation, reference numerals being maintained unaltered).
  • FIG. 1 shows a view from above of a drive unit 150 for conveying the substratum 217 during the plating process.
  • the drive unit 150 comprises the following parts: an actuator in the form of a chain 152 fitted with mounting means for the gripping devices 124 placed one next to another; a drive supporting frame 156, a motor with gear box 158 for driving the chain 152, and a tensioning gear 160 placed at one end where the chain 152 makes its rotating movement. Apart from these points of rotation, concentrated at its two ends, the chain 152 and the gripping devices 124 follow a substantially rectilinear path, as indicated by the arrow A, along the longest side of the frame 156.
  • the substratum 217 is gripped at the beginning of the straight length and is dropped just before the straight length terminates.
  • the cupric ion in a Cu ++ solution migrates from the electrified substratum to the cathode, by means of the pincer means on the gripping device, where it takes the form of a layer of metal copper evenly laid on the surface of the substratum as well as inside the holes.
  • the hydroxyl group OH becomes oxidised leaving the hydrogen ion H + in an aqueous solution which acidifies it and which must therefore be buffered.
  • FIG. 1 gives an axonometric ,view of a gripping device 124 in the electroplating device belonging to the previously known art, shown when open and without substratum 217 ( Figure 1).
  • the gripping device 124 comprises a non-metal housing 166 (of polypropylene or polyethylene), a metal component 168, a flat support 172 able to pivot, and a sealing device 176 consisting of an elastic cone-shaped packing.
  • the non-metal housing 166 comprises a T-shaped component 178 and a second component 180.
  • the plastic component 178 has a central body 182 and two arms 184 that extend perpendicular to the body.
  • the second component 180 also defines a passageway 170 ( Figure 3) that receives the central body 182 of the T-shaped component 178.
  • the second component 180 further contains a mounting part with a plurality of holes for screwing the mounting connection onto the drive- chain 152.
  • Springs are placed between the two arms 184 of the T-shaped component 178 and the second component 180 below, their purpose being to render elastic the sliding movement made by the central body 182 into the passageway 170 ( Figure 3).
  • the gripping device 124 is symmetrical to a plane that passes through the axis A-A. •
  • Figure 3 shows the section A-A in Figure 2, where it will be seen that the metal component 168 comprises the following conductors of electricity: a metal roller 206, a pin 208 for rotating said roller, a first contact 197 and a second contact 199, both of a substantially lengthened rectangular shape, a first spring 200 and a second spring 202, these being more rigid than the previous ones, a braided or plaited conductor 204 fixed by screws 218 to contacts 197 and 199.
  • the pin 208 is in contact both with the roller 206 and with the walls of a housing for the roller made in the upper part of the first contact 197 which also marks a lower opening 198 for the conductor 204.
  • the second contact 199 defines an opening 210 for the conductor 204 and presents an extension 212 which, when closed, crosses through an opening 214 in the lower wall of the central body 182 which is continuous with the cavity 186 (see Figure 4).
  • the first spring 200 is placed between the first contact 197 and the second contact 199.
  • the second spring 202 is situated between the second contact 199 and the base of the cavity 186. Beyond the edge of the opening 214, the base of the central body 182 presents a short narrow extension to permit application of the seal packing 176.
  • the flat support 172 is substantially L-shaped, the shorter arm of which is connected to the housing 166 by a pin 213 around which it can make a partial turn so forming, together with the other arm, a passageway 174 for the substratum 217 (see Figure 4).
  • the rectilinear movement of the gripping device 124 carries the roller 206 below a collector of anodic current in the form of a bar that slopes downward in the direction in which the initial stretch moves.
  • the T-shaped component 178 is pressed inside the cavity 170 until it comes in contact with the upper face- of the substratum 217 and engages the seal packing 176.
  • the extension 212 of the cathode contact 199 is kept insulated from the plating solution.
  • the springs possessing greater rigidity also become compressed by thrust from the roller 206 until the extension 212, penetrating inside the cavity 214, reaches the substratum to provide the cathode contact.
  • Figure 4 shows how the end section of the gripping device would appear when closed, with both the seal packing 176 and the extension 212 of contact 199 pressed against the substratum 217 in order to ensure a mechanical grip and supply a cathode contact, insulated from the electrolytic solution, when current passes through it.
  • the main drawback to the gripping device just described is that it does not ensure an uniform distribution of the plating material on both sides of the substratum through the holes, this because cathode contact is present on one side only of the substratum.
  • Purpose of the present invention is to overcome the drawbacks explained above and suggest how to provide a gripping device with an improved cathode contact able to ensure that said device can be more satisfactorily used in an electroplating apparatus such as that described for the production of printed circuit boards (PCB or PWB). .

  • said first and second means of electrification and grip are coated with a layer of electrically insulating material resistant to acids, except for the surfaces in contact with the substratum to be plated, the dimensions of which are those strictly necessary for satisfactory operation.

Abstract

La présente invention concerne un dispositif d'accrochage et d'électrification cathodique d'un substrat diélectrique pour fabriquer des cartes de circuits imprimés, de nombreux dispositifs d'accrochage étant montés sur un convoyeur à chaîne qui guide le substrat, soutenu par lesdits dispositifs d'accrochage, à l'aide de deux séries de rouleaux opposés qui appliquent une solution de galvanisation par électrolyse. Le dispositif d'accrochage comprend un support isolant fixe à l'intérieur duquel coulisse un autre support, les deux supports étant séparés par des ressorts. Ces supports transportent chacun des électrodes de type pinces en forme de L pour s'accrocher au substrat, les bras les plus courts se superposant pendant l'action d'accrochage et les pointes respectives s'étendant à l'opposé l'une de l'autre à l'image d'une paire de pinces. Les électrodes en titane en forme de L sont plaquées avec un matériau isolant à l'exception des pointes. Le dispositif d'accrochage comprend également un contact en cuivre de la forme d'un coulisseau qui repose sur les ressorts à l'intérieur du support isolant coulissant. Pendant la translation du dispositif d'accrochage, le coulisseau coulisse contre une barre en cuivre située au-dessus de celui-ci qui fournit le courant de la cathode. Une extrémité de la barre est inclinée vers le substrat dans la direction de translation. Des branches flexibles externes relient le coulisseau aux électrodes-pinces. Un bouton-poussoir, détaché du coulisseau, est pressé contre la barre externe par un ressort central solide placé à l'intérieur du support isolant coulissant.
