Abstract
Abstract In an assembly of circuit components, such as a multiplicity of RF interference suppression filters, the filter elements (15) in a first array are secured to a first plate (16) at solder joints (17) and further filter elements (18) in a second array are secured to a second flat plate (19) at solder joints (20). The first array of filter elements (15) thus extend through apertures (21b) in the second plate (19) and the second array of filter elements (18) extend through apertures (21a) in the first plate (16). The plates (16) and (19) are secured together after the soldering operation and the interspersed arrays of filter elements (15) and (18) can be individually inspected as to the adequacy of the solder joint.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
An assembly of circuit components for electrical circuitry comprising at least two adjacent plates, each plate having mounted thereon a respective part-array of components and each plate defining spacing apertures interspersed among said part-array of components mounted to said plate, said plates being arranged side-by-side with said part-array of components on each plate extending through the spacing apertures in, but not attached to, the other adjacent plate to form a completed array and the plates being secured together.
Claim 2
Dependent Claim
78 words
An assembly of circuit components for electrical circuitry comprising at least two adjacent plates, each plate having mounted thereon a respective part-array of components and each plate defining spacing apertures interspersed among said part-array of components mounted to said plate, said plates being arranged side-by-side with said part-array of components on each plate extending through the spacing apertures in, but not attached to, the other adjacent plate to form a completed array and the plates being secured together.
Claim 3
Dependent Claim
16 words
An assembly according to claim 1, in which the plates are spaced apart slightly by shims.
Claim 4
Dependent Claim
20 words
An assembly according to claim 1, in which the plates are secured to one another to form a composite sub-chassis.
Claim 5
Dependent Claim
20 words
An assembly according to claim 1, wherein each respective plate has secured thereon said respective part-array of components by soldering.
Claim 6
Dependent Claim
14 words
An assembly according to claim 1, in which said circuit components comprise filter elements.
Claim 7
Independent Claim
160 words
A method of making an assembly of circuit components comprising the steps of providing at least a first and a second plate, each with apertures therein corresponding to a desired array, inserting first circuit components in a first sub-array of the apertures in said first plate leaving a second sub-array of said apertures interspersed among said first circuit components and securing the first circuit components to said first plate, inserting second circuit components in the second sub-array of the apertures in said second plate leaving the first sub-array of said apertures interspersed among said second circuit components and securing the second circuit components to said second plate, placing the plates in side-by-side relationship with the first circuit components secured to the first plate received in the first sub-array of apertures in the second plate and the second circuit components secured to the second plate received in the second sub-array of apertures in the first plate, and securing said plates together.
Claim 8
Independent Claim
160 words
A method of making an assembly of circuit components comprising the steps of providing at least a first and a second plate, each with apertures therein corresponding to a desired array, inserting first circuit components in a first sub-array of the apertures in said first plate leaving a second sub-array of said apertures interspersed among said first circuit components and securing the first circuit components to said first plate, inserting second circuit components in the second sub-array of the apertures in said second plate leaving the first sub-array of said apertures interspersed among said second circuit components and securing the second circuit components to said second plate, placing the plates in side-by-side relationship with the first circuit components secured to the first plate received in the first sub-array of apertures in the second plate and the second circuit components secured to the second plate received in the second sub-array of apertures in the first plate, and securing said plates together.
Claim 9
Dependent Claim
41 words
A method according to claim 6, in which said first circuit components are soldered to said first sub-array of apertures in said first plate and said second circuit components are soldered to said second sub-array of apertures in said second plate.
Claim 10
Dependent Claim
56 words
A method according to claim 7, further comprising the initial step of soldering each said first and second circuit components to respective feed-through wires with a higher melting point solder, and in which said first and second circuit components are soldered to the respective first and second plates by means of a lower melting point solder.
Claim 11
Dependent Claim
14 words
A method according to claim 6, in which said circuit components comprise filter elements.
Claim 12
Dependent Claim
151 words
An assembly of circuit components for electrical circuitry comprising at least first and second planar plates, said plates being mounted adjacent and parallel to each other, each of said plates defining a plurality of apertures, a first plurality of component means fixed to said first plate mounted in a first subset of said defined apertures in said first plate, a second plurality of component means fixed to said second plate mounted in a second subset of said apertures defined in said second plate, said first plurality of components extending through unoccupied apertures of said second plate interspersed among said second plurality of components, said first plurality of components being unattached to said second plate, said second plurality of components extending through unoccupied apertures of said first plate interspersed among said first plurality of components, shim means mounted between said plates to space said plates and means to secure said plates together.
Claim 13
Dependent Claim
151 words
An assembly of circuit components for electrical circuitry comprising at least first and second planar plates, said plates being mounted adjacent and parallel to each other, each of said plates defining a plurality of apertures, a first plurality of component means fixed to said first plate mounted in a first subset of said defined apertures in said first plate, a second plurality of component means fixed to said second plate mounted in a second subset of said apertures defined in said second plate, said first plurality of components extending through unoccupied apertures of said second plate interspersed among said second plurality of components, said first plurality of components being unattached to said second plate, said second plurality of components extending through unoccupied apertures of said first plate interspersed among said first plurality of components, shim means mounted between said plates to space said plates and means to secure said plates together.
Claim 14
Dependent Claim
58 words
An assembly of circuit components for electrical circuitry as claimed in claim 10 wherein the component means are secured to said plates by solder, said component means being provided with lead wires soldered thereto, said solder for said lead wire having a substantially higher softening point than the solder by which the components are soldered to the plate.
