Definitions
- Miniaturized electrical and electronic components are usually inserted into a housing using a die-bond process and bonded there.
- this adhesive process in machine production means that the components scatter more in their properties after bonding than before bonding. This is due in particular to the different expansion coefficients of the component and the base or housing.
- the tension builds up when the adhesive point is cured at a temperature above the operating temperature of the component, and is therefore stress-free only at this curing temperature.
- the sensitive, crystalline substrate supporting the component structures is provided by a
- Adhesive is connected to a system carrier, spacing structures being arranged in a regular pattern between the substrate and the system carrier, support points or surfaces lying in one plane being formed on which the substrate and / or the system carrier rests.
- a spacing structure is also possible, which forms support points lying on a straight line. direct contact between the system carrier and the substrate is provided. It is further provided that the space between the spacing structures, the substrate and the system carrier is completely and largely free of air pockets or partially of adhesive.
- the arrangement and number of support points or surfaces as well as the angle between the substrate and the system carrier are predefined, which was rather left to chance in a conventional mechanical die-bond process and therefore led to undefined support points which, owing to Fluctuations in the material properties of the system carrier lead to different tensions.
- the distance between the substrate and the system carrier specified by the support points or surfaces also ensures a sufficiently thick adhesive layer between the substrate and the system carrier over all the components produced. Adequate damping of the tension between the glued different materials of component and system carrier is therefore ensured by a sufficient layer thickness of adhesive. As a result, components are obtained which have only a small scatter of their properties even within large quantities, and which can therefore be produced with a high degree of reproducibility and thus with less rejects.
- spacing structures are provided which result in point-like support points.
- Component substrate are distributed over the surfaces to be glued.
- the version with three support points has the advantage that the support points are always in one plane.
- strip-shaped spacing structures are provided which form strip-shaped contact surfaces which are parallel to one another.
- strip-shaped spacing structures are advantageous if they are interrupted in the middle. This creates an opening that leads to a better distribution of the amount of adhesive during gluing.
- the space between the spacing structures, the substrate and the system carrier is thus filled with adhesive. This leads to a defined volume and defined limits of the adhesive layer, the properties of which must therefore be maintained more consistently because of the good reproducibility.
- the spacer structures preferably consist of a screen-printable mass, which is applied to the system carrier or to the substrate by means of screen printing.
- Such spacing structures are particularly easy to manufacture. It is nevertheless ensured that a uniformly high spacing structure or support points or surfaces lying in one plane can be formed.
- the invention is particularly advantageous for frequency-accurate surface acoustic wave components which are particularly frequency-stable with the adhesive bonding according to the invention, so that only a small error scatter at the center frequency is observed in mass production.
- the invention in particular unavoidable unevenness in the surface, in particular of the system carrier, can be compensated and a uniform layer thickness of the adhesive used in the die-bond method between substrate and system carrier can be ensured.
- the advantages of the invention can therefore be safely obtained even in the case of materials which become thinner, despite their greater susceptibility to bending and unevenness.
- the gluing process becomes more stable and less sensitive to fluctuations in the quality of the system carrier and the glue application.
- the invention is suitable for all components on, in particular, crystalline substrates which are sensitive to tension.
- This can be electrical, electronic and also be special passive components, such as the surface wave components mentioned.
- the system carrier can be a printed circuit board, in particular a multilayer comprising several metallization levels
- Plastic plate a ceramic substrate plate, which may have conductor tracks and / or plated-through holes, or in particular a two-part housing, it being possible for the substrate to be connected to the housing base or the housing cover.
- the housing can be made of ceramic or metal.
- the spacing structures preferably consist of screen printing structures.
- the spacer structures can be made from other materials, in particular from metal, glass or mixed organic / inorganic pastes, for example from metallization pastes that can be processed with screen printing.
- the spacing structures can be applied directly to one of the surfaces of the substrate or system carrier, or can be applied to the substrate in a prefabricated form.
- the direct build-up on the surface of the substrate or system carrier can be achieved, for example, by applying an appropriate material layer over the entire surface in the desired thickness and then structuring the same to form the spacing structures mentioned.
- the spacing structures can optionally be applied to the surface of the substrate or the system carrier.
- the adhesive used is preferably a thermally curable elastomer. This can be applied with the appropriate application devices even in the smallest doses for the smallest components in the desired quantity and at the desired location.
- the dimensions of the spacing structures depend on the size and type of the component to be bonded. In general however, a height of 10 to 50 ⁇ m is sufficient for me. This height also determines the thickness of the adhesive layer, which is sufficient to absorb the majority of the stress gradient between the different materials. This enables the majority of the tension to be located within the adhesive layer.
- the spacing structures form defined support points and surfaces
- a thin adhesive layer with a typical thickness of approximately 1 ⁇ m is also formed between these support points and surfaces and the surface to be glued when the adhesive is applied.
- this is small compared to the total adhesive thickness and does not impair the advantages associated with the invention. It can be guaranteed that the space between substrate, leadframe and spacing structures is completely filled by the adhesive, avoiding air pockets, if this is desired.
- Figures 1 to 4 show a system carrier with various spacing structures applied thereon in a schematic plan view
- FIG. 5 shows a substrate connected to a system carrier in a schematic cross section
- FIG. 6 uses a graphic to show the improved standard deviation of a parameter of the component
- a surface acoustic wave resonator is to be installed in a ceramic housing by means of die bonding.
- FIG. 1 shows the lower part of the component housing into which the component substrate is to be glued. Also shown is the housing wall GW, the small thickness of which can lead to higher dispersion of the housing geometry.
- Metallized connection areas AF are also indicated on the bottom of the lower housing part, which are used for the later electrical connection to the component, for example via bonding wires.
- a predetermined pattern of spacing structures AS is now printed on the substrate carrier ST, that is to say on the bottom of the lower housing part, for example by means of screen printing. In FIG. 1, these are three similar, approximately punctiform structures, which are distributed uniformly over the base area of the substrate delimited by dashed line BS. The uniform height of the spacing structures AS is ensured by the application process, but can also be corrected additionally.
- four spacing structures AS are provided in the vicinity of the four corners of the component substrate BS, which form the corresponding support points.
- the number of spacing structures or support points can also be increased for larger components or substrates.
- FIG. 3 shows two strip-shaped support structures which are parallel to one another and form the same strip-shaped contact surfaces.
- FIG. 4 shows an advantageous variation of strip-shaped spacing structures AS.
- two strip-shaped spacing structures AS are provided, which, however, have a recess or an interruption U in the middle. This creates four separate contact surfaces.
- the interruption in the middle of the strip-shaped spacing structures AS has the advantage that excess adhesive can pass through the recesses during the placement of the component substrate BS and can thus be better distributed. This leads to a higher level of process reliability, or simpler placing of the substrate on the support surfaces.
- FIG. 5 shows a finished adhesive site using a schematic cross section. It can be clearly seen that the surfaces of component substrate BS and system carrier ST facing or glued to one another are aligned parallel to one another due to the similar spacing structures AS.
- the spacing structures are shown here as hemispherical in cross-section, but the cross-section is not critical and essentially only depends on the manufacturing method of the spacing structures.
- By means of screen printing for example, rectangular structures with only rounded edges can also be produced in cross section.
- Other cross sections are also possible and conceivable. It is only important that the contact points or contact surfaces come to lie in one plane or approximately in one plane.
- the adhesive K which is applied to one of the two surfaces of the substrate or system carrier and is distributed evenly and without air-like inclusions after the two parts have been joined together, can be dimensioned in such a way that it covers the entire space between the system carrier ST and the component substrate BS fills.
- the base area of the component substrate BS In the case of spacing structures AS that are correspondingly far apart, it is also possible for the base area of the component substrate BS to match the area delimited by the spacing structures AS. This has the advantage, in particular in the case of surface acoustic wave components, that the entire surface (base area) of the substrate BS is dampened by the adhesive layer, as a result of which, for example, disturbing bulk waves are dampened and prevented from being reflected back into the component structures. Tensions in the substrate are also better transmitted or distributed.
- FIG. 6 shows the scatter of a parameter of the component which is sensitive to tension in the substrate in the case of components bonded according to the invention in comparison with conventionally bonded components.
