Definitions

  • the present invention relates to a containing apparatus for electronic parts, and particularly to an electronic part container used in an electroplating process, whereby bending of lead wires of an electronic part may be prevented during the electroplating operation and the deposition thickness is relatively even, and what is more the apparatus is capable of being incorporated into an automatic production line so as to enhance production efficiency and prevent hazards induced by manual operation.
  • the conventional apparatus is provided with a plurality of tanks "A" and a metal piece such as tin, lead, copper, silver, and the like, serving as an anode.
  • the electrically-conducting shaft is provided with a plurality of electrically-conducting rings "D'" so as to avoid collisions between electronic parts in the rolling barrel.
  • the bending problem still cannot be solved effectively. This is because electronic parts are randomly disposed in the rolling barrel "C” of the apparatus.
  • the space inside the barrel "C” is relatively large, the chance of collision between electronic parts during the electroplating operation is very high. As a result, close to the ends of an electronic part the lead wires will suffer from being bent, and then the bent leads must be straightened manually. Consequently, human resources are wasted.
  • the conventional apparatus has the following disadvantages:
  • the present invention provides a containing apparatus as defined in claim 1.
  • the plurality of spikes enhance the probability of contact between the electronic parts and the cathode.
  • the electronic parts have their lead wires kept from being bent so as to eliminate the necessity of straightening bent wires.
  • the containers are each positioned substantially tangential to the shaft so the fluidity of electrolyte is increased and hence the uniformity of the electroplating thickness is easily achieved.
  • the containers are preferably so spacious that the electronic parts therein will not crowd together, so the coating on the surface of the electronic part is complete, namely it is of better quality.
  • the containing apparatus 1 of the present invention for electronic parts mainly comprises a rotating cage 4 and a plurality of electronic part containers 2.
  • Each of the connecting seats 42 comprises a guiding slot 45 for guiding and receiving the respective electronic part container 2 therein and a knob 43 for fixing the container 2 in the guiding slot 45.
  • the containers 2 are arranged in a tangential direction.
  • the rotating cage 4 is provided with a plurality of connecting seats 42 which are substantially tangential to a rotation axis (as indicated by phantom line 41') thereof. By the provision of the connecting seats 42, the rotating cage 4 is able to receive containers 2.
  • the connecting seat 42 is further provided with an electrically-conducting copper piece 44 which is capable of being in contact with electrically-conducting copper pieces on two ends of the container 2 so as to form a current path.
  • the rotating cage 4 is connected to the conventional actuating rod "F" so as to move around in the tank "A".
  • the container 2 takes the form of a thin rectangular box.
  • the thin box 2 is provided with a plurality of baffle plates 22 which are evenly spaced so as to define a plurality of compartments 21.
  • Spikes are provided on the side walls of each compartment 21 so as to form spiky walls 23 made of electrically-conducting material.
  • the spiky walls 23 are connected to the electrically-conducting copper pieces 24 on the two ends of the container 2.
  • the container 2 has a cap 25 which is able to keep electronic parts therein from dropping out.
  • the cap 25 has a liquid-permeable screen 26 thereon and the bottom of the container 2 is also liquid-permeable. By means of the water-permeable characteristics of the container 2, the electrolyte is easily circulated.
  • each electronic part 3 is perpendicular to the spiky walls such that the lead wires of each electronic part are able to contact with the spiky walls 23. Since the orientation of every electronic part 3 is the same, and no collision with another occurs, the lead wires 31 of the electronic parts 3 will be almost clear of risk of being bent. Furthermore, the probability of contact between the electronic parts and the cathode is greatly increased.
  • the electroplating apparatus of the present invention is able to achieve the following advantages:
  • the present invention makes the thickness of the zone L.C.D. and that of the H.C.D. zone almost equal. Therefore, the quality of the electronic part can be improved.
