Definitions
- the device object of the present invention has the function of filling blind cavities with viscous products.
- the filling of blind cavities with a viscous product is made difficult by the fact that the air or gas present in the cavity as well as the viscosity or the surface tensions of the product are opposed to the good filling of small cavities or cavities that have chokes.
- the fields of application of the present invention are multiple, by way of nonlimiting example, it is applicable in fields such as electronics, medical, chip connection vias for smart cards, ... It is particularly suitable for filling micro-cavities in the space and military fields.
- one technique consists in carrying out this operation under vacuum.
- the cavities to be filled are placed in a closed enclosure in which a vacuum is applied, then the product is forced into the cavities by means of a syringe or a dispenser.
- This technique although functional, has a number of drawbacks, such as:
- the vacuum enclosure must be large enough to receive the injection system, which means that the vacuum pump must be dimensioned accordingly.
- this type of equipment does not lend itself to mass production of the scrolling type because it is necessary to provide entry and exit airlocks between the inside and the outside of the vacuum chamber or then provide a step forward step and redo the vacuum with each step. In any case, this type of equipment becomes extremely complex and expensive.
- to pass a viscous product into cavities of small size or having constrictions it is necessary to inject the product under pressure at the level of the orifices to force it to fill.
- the first slot is connected to a vacuum generator, while the second is connected to a reservoir containing the product.
- the first slot connected to the vacuum is spaced tightly from both the outside and the second slot by a distance, measured parallel to the movement of the device, greater than the dimension of the largest orifice of the cavities to be filled and a seal perfect is achieved between the surface having the two slots and the upper face of the substrate having the cavities to be filled.
- the orifices of the cavities are not located in a plane which makes it possible to achieve sealing with the contact surface of the device or even if it is desired to avoid bringing the product into contact with the surface of the substrate , it is possible to insert an intermediate mask between the device and the substrate to be filled.
- the mask can be produced by a metallic or synthetic sheet which will be pressed in intimate and tight contact with the substrate. It is also conceivable to use a mask, temporary or not, produced from a photoimageable film laminated or bonded to the substrate. Similarly, by inserting a mask between the device and the substrate, it is possible to carry out a screen printing operation.
- the blind cavity is produced by the opening of the mask and the substrate and when, after passage of the device, the mask is separated from the substrate, there will remain a deposit of product in excess thickness on said substrate.
- the present invention can therefore advantageously be adapted on a screen printing machine and in this case, so that the system can operate in both directions, it is conceivable to place a third slot identical to the first and placed opposite to the second and in this case the vacuum will be applied alternately in the first or third slot depending on the direction of movement of the device.
- scraper blades can for example be made from a single curved blade and pierced so that the two ends are at the front and rear of the dispensing slot and that the holes allow the passage of the product .
- a pressing force can be exerted to press the blades in contact with the surface to be scraped,
- Figure 1 shows in section a device according to the invention.
- Figure 2 shows a bottom view of the device according to the invention.
- Figure 3A shows in section a variant of the device according to the invention applied to the filling of a conventional stencil on a screen printing machine.
- FIG. 3B represents in section the device filling the cavities arranged on a substrate on which is affixed a thin intermediate stencil of cleanliness.
- Figure 4 shows in section another variant of the device according to the invention.
- FIG. 5 represents a sectional view of the device applied to the filling of identical or different tubes positioned on a common support.
- Figure 6 shows a top view of the device according to the invention mounted on a screen printing machine in place of a doctor blade.
- FIG. 7 represents a use of the method for the encapsulation of electronic chips.
- the body (1) comprising a first depression slot (2) connected to a vacuum chamber (3) which itself is connected to a vacuum generator (4) of any known type.
- a second slot (5) called distribution is connected to a reservoir (6) containing the product (7).
- the body (1) can be set in relative movement relative to the substrate (8) in the direction (D) while maintaining a sealed contact between the face (9) of the body (1) relative to the face (10) of the substrate (8) comprising the cavities (11) to be filled.
- the orifices (12) of the cavities (11) to be filled are successively: - sealed in relation to the outside of the device,
- each cavity is therefore successively subjected to the vacuum in contact with the depression slot (2), without this same cavity being able to be simultaneously in contact either with the outside of the device is with the second slot (5), then at the filling phase by suction of product (7) in contact with the dispensing slot (5).
- the vacuum applied in the cavity in contact with the slot (12) is maintained until the product is in contact with this same cavity, the product being at a pressure higher than that prevailing in the cavity, it is therefore sucked there until the pressure there is equal to the pressure prevailing in the product reservoir. If the vacuum is sufficiently high and if the product present in the tank does not present any air bubbles, this device makes it possible to fill cavities completely and homogeneously whatever the viscous product.
- FIG 2 is shown the face (9) of the body (1).
- the depression slot (2) here surrounds the distribution slot (5) on three sides, thus maintaining the vacuum between the two slots is perfectly ensured and therefore allows optimum filling.
- This arrangement is particularly suitable because it also allows optimum plating between the faces (9) and (10) thanks to the vacuum prevailing in the slot (2) and thus the sealed contact between the two faces is ensured. It is possible to further improve the sealed contact to add seals on the face (9) or else to produce the lower part of the body (1) in deformable material such as polyurethane for example.
- FIG. 3A represents another mode of use of the device according to the invention applied to a conventional screen printing.
- the blind holes are formed by the upper surface of the substrate which is in contact with the stencil (13), in which the openings (14) form the cavity to be filled.
- FIG. 3B represents another mode of use where the upper face of the substrate must not come into contact with the product or the surface of the substrate does not not allow the device according to the invention to slide tightly.
- a scraping blade (15) for example made of stainless steel, disposed at the rear of the dispensing slot (5) proves to be particularly effective.
- this scraper blade can be produced by a curved spring blade in which openings (16) have been made to allow the passage of the product.
- a force (FI) applied by a device not shown, provides a perfect seal and prevents the creation of a thin film of product on the surface of the mask (13) or the substrate (8).
- This device according to the invention can advantageously be used for a screen printing operation, and in this case, it may be necessary to be able to operate alternately in both directions. For this, it suffices to add a third slot (18) identical to (2), symmetrically with respect to (5) and connected to a vacuum chamber (19). In this case, during a movement in the opposite direction to D, the vacuum is applied in (19) keeping (3) at atmospheric pressure and vice versa for a movement in the direction of D.
- a force (F2) can be judiciously applied to the body (1) to press the different surfaces against each other.
- Figure 4 shows in section another embodiment of the present invention.
- the body (1) has in its part in contact with the substrate (8), a part (22) deformable to conform to the irregularities of the surface (10) or of the mask (13) if any. makes use of, without affecting the perfect sealing of contact with the surface (9).
- the scraping of the surplus product is ensured in this case by an elastic blade (25) fixed on the rear part of (1) by a means not shown and which has an angle ce greater than or equal to 90 degrees.
- Figure 5 shows in section another possible form of application.
- the goal is to collectively fill identical or different tubes (23).
- the tubes (23) are positioned on a support plate (24). Each tube is in perfect support on the plate so as to avoid any leakage.
- a very thin sealing and cleanliness stencil (13) with openings in place of the tubes to be filled is positioned above the latter.
- the device (1) according to the invention moves on the surface and makes it possible to fill the tubes (23) with the product.
- FIG. 6 shows how the device (1), object of the present invention, can be adapted in place of the doctor blade (26) on a screen printing machine.
- the substrates (8) are brought by the conveyor (27) and the screen printing is carried out through the mask (13).
- the device according to the present invention therefore makes it possible, as has been said previously, to completely and perfectly fill blind cavities. But it also allows partial filling or blocking of blind cavities by adjusting the value of the vacuum in the vacuum chambers (3) or (19). In fact, the value of the pressure differential between the product reservoir and the vacuum chambers conditions the quantity of product which will be drawn into the cavity.
- the device according to the invention provides access to new applications in the field of interconnection and packaging, also called packaging or encapsulation for electronic applications.
- the device for filling metallized holes in a printed circuit also called bushings
- a hardenable and machinable insulating resin Said holes are previously blinded by any means during the filling time.
- a new drilling is then made in the insulating resin whose diameter is less than the first hole and this new hole is metallized in connection with the upper and / or lower faces.
- concentric multi-layer metallized holes The operation can be repeated for a number of layers greater than 2, if this is desired.
- this method for carrying out encapsulation of electronic chips on a substrate by an insulating and curable material.
- a mask the openings of which constitute a mold and the walls of which are of negative draft so as not to entrain product during demolding.
- this negative draft it is it is possible to completely fill the volume defined by the mask by using the device.
- Figure 7 shows the principle of this application and in particular the form of an example mask (28) covering the chip (29) and the hole (30) through which the product will pass.
