Definitions

  • the present invention relates to a method for feeding encapsulating material to a mould cavity for the purpose of encapsulating electronic components.
  • the invention also relates to a device for feeding encapsulating material to a mould cavity for the purpose of encapsulating electronic components, and to a mould for encapsulating electronic components which can be applied in combination with such a feed device.
  • thermocuring material which is also referred to as epoxy or resin, which normally includes silicon as filler material.
  • a carrier with semiconductors is clamped and in which spaces are also incorporated for placing pellets of encapsulating material. Provisions are also arranged in such a mould for heating the encapsulating material and for exerting pressure on the encapsulating material. Through being heated and/or placed under pressure the encapsulating material is activated such that, once it has been displaced to mould cavities closing around the electronic components, it cures after a limited time.
  • the mould is opened and the carrier with encapsulated components is then taken out, including the remaining cured encapsulating material (such as remnants of the pellets and the encapsulating material cured in feed channels).
  • the existing method results in a controllable encapsulating process with a relatively long cycle time, since placing the encapsulating material and the products in the mould, closing the mould, activating and displacing the encapsulating material, at least partially curing the encapsulating material, opening the mould, removing the encapsulated products and cleaning the emptied mould all successively form part of the critical path of the method.
  • the object of the present invention is to provide a method, and the associated means, for shortening the cycle time for encapsulation of electronic components. It is also an object to increase the efficiency of the encapsulation.
  • the invention provides for this purpose a method for feeding encapsulating material to a mould cavity for the purpose of encapsulating electronic components, comprising the processing steps of: A) at least partially activating in a feed device the encapsulating material for feeding, B) coupling to the feed device a mould cavity with an electronic component for encapsulating, C) carrying the at least partially activated encapsulating material from the feed device into the mould cavity, and D) uncoupling the feed device and the mould cavity at least partially filled with encapsulating material. It thus becomes possible to at least partly separate, and perform (at least partially) as parallel operations, the feeding and activating of the encapsulating material from the placing in the mould cavity of the electronic components for encapsulating.
  • the encapsulating material is preferably at least partially activated during processing step A) by means of heating, optionally in combination with, or as alternative to, exerting pressure on the encapsulating material.
  • the advantage here is that use can be made of the existing (and therefore accepted and readily obtainable) encapsulating material.
  • Alternative methods of activating encapsulating material can however also be envisaged, such as for instance activating encapsulating material ultrasonically or with ultraviolet.
  • a further improvement of the method can be realized by discharging the gases released from the feed device separately of the encapsulating material.
  • the fluid released by degassing the encapsulating material can thus be discharged before it enters the mould.
  • the method according to the invention now provides the option of removing (a part of) the gases developing during the at least partial activation of the encapsulating material before they enter the mould. This option is lacking in encapsulation according to the prior art because there the encapsulating material is fully activated in the mould.
  • an opening of the feed device takes place during coupling of the feed device to the mould cavity as according to processing step B). It is thus possible to prevent encapsulating material being released in undesirable manner from the feed device when this latter is not coupled to a mould cavity (mould). Another significant advantage is that ageing of encapsulating material in the feed device can thus be limited or, in extreme situations, can be stopped. It is desirable for this purpose that closing of the feed device takes place during uncoupling of the feed device and the mould cavity as according to processing step D).
  • the invention also provides a device for feeding encapsulating material to a mould cavity for the purpose of encapsulating electronic components, comprising: a container for containing inactivated encapsulating material, activating means connecting onto the container for at least partly activating the encapsulating material, transport means for displacing the encapsulating material from the container along the activating means, and an outlet connecting to the activating means for the at least partly (or fully) activated encapsulating material.
  • the activating means are formed by heating means, for instance a contact heating and/or another radiation source.
  • the heat can also be transmitted as infrared radiation, the heat can be generated with a heating element which excites microwaves, or use can be made of a high-frequency heating source (HF heating).
  • HF heating high-frequency heating source
  • At least partial activation is here understood to mean initiation (or acceleration) of the process of curing the encapsulating material, and this at least partial activation can be, but does not necessarily have to be, initiated by supplying heat. Other methods of activation can also be envisaged, such as for instance supplying an additional (for instance catalyst) substance, applying pressure and so forth.
  • the transport means can comprise at least one plunger for urging the encapsulating material out of the container and along the activating means to the outlet.
  • the encapsulating material can be fully activated in the feed device, but it is also possible to envisage the feed device only partially activating the encapsulating material and the encapsulating material subsequently being fully activated in for instance the mould cavity.
  • the outlet is provided with a coupling adapted for co- action with a mould defining the mould cavity around an electronic component.
  • a coupling makes it possible to realize a coupling between the components in rapid and medium-tight manner.
  • the outlet is desirably provided with a closing valve.
  • This can for instance be embodied in the form of for instance a closing valve which can only be opened, or automatically opens, by coupling the outlet to a mould.
  • the closing valve can for instance be embodied as a closing pin for displacing in and out of a nozzle in flow direction.
  • the device can also be provided for this purpose with cleaning means with which at least partly activated encapsulating material can be removed from the feed device after it has been present in the encapsulating device for a minimal period in at least partly activated state. If the at least partly activated encapsulating material is not removed quickly enough from the feed device, it can begin to cure in the encapsulating device and thus impede functioning thereof. This can be prevented by means of the cleaning means.
  • the invention also provides a mould for encapsulating electronic components, comprising at least two mould parts displaceable relative to each other and adapted to receive a carrier provided with at least one electronic component such that the electronic component is received in a mould cavity, wherein the mould is also provided with a mating coupling which connects to the mould cavity and which is adapted for co-action with a feed device for encapsulating material.
  • a mould has a simple construction compared to existing moulds, is therefore relatively inexpensive and can be embodied such that it is simple to clean.
  • closing means for closing the mating coupling means can prevent encapsulating material which has not yet cured from leaving the mould in undesirable manner and/or prevent contaminants entering the mould in undesirable manner.
  • the invention furthermore provides an encapsulating device for encapsulating electronic components, comprising an assembly of a feed device as described above and at least one mould, likewise as described above, co-acting with the feed device.
  • an encapsulating device is preferably provided with a plurality of moulds which are displaced relative to the feed device with a (for instance endless) transport system.
  • the number of moulds can now be adapted to the single feed device (or optionally the plurality of feed devices) such that optimal use is made of the capacity of both the feed device(s) and the moulds. In addition, such a device becomes less susceptible to malfunction and maintenance.
  • Such a device can also be provided with a discharge device for removing from a mould an electronic component enclosed with encapsulating material, with stationary closing means for closing the mould parts displaceable relative to the closing means, and/or with stationary opening means for opening the mould parts displaceable relative to the closing means.
  • the encapsulating process can thus be automated to a greater or lesser extent.

  • the encapsulating material 3 will be displaced in a direction as according to arrow P2.
  • Encapsulating material 3 is thus urged to a heating space 7 which connects onto transport tube 4 and on the sides of which schematically shown heating elements 8 are disposed.
  • Heating elements 8 transfer heat to encapsulating material 3 situated in heating space 7, whereby it is activated and whereby it can only remain for a limited time in heating space 8.
  • Activated encapsulating material 3 can be extracted from heating space 8 by opening a tap 9 connecting onto heating space 8.
  • Figure 1 also shows moulds 10, 10' whereby a carrier 11 with a chip 12 is enclosed such that a mould cavity 13 is left clear around chip 12.

  • Moulds 10, 10' are also provided with a feed channel 16, 16' for activated encapsulating material 3.

  • Plunger 22 will have an intermittent pattern of movement during the forward movement of which the encapsulating material 25 is displaced through feed device 20.
  • Encapsulating material 25 can herein pass through successive zones in which there are different process conditions.
  • FIG. 2C shows feed device 20 in yet another situation, i.e. a situation in which discharge channel 28 is opened by displacing a housing 29 of the second plunger 27 relative to supply container 21 and transport tube 23, which housing 29 simultaneously forms a part of discharge channel 28.
