Abstract First workpieces, for example, beam-leaded integrated circuits, and the like, are bonded to second workpieces, for example, metallized ceramic substrates by first depositing a quantity of primary explosive, such as lead azide, onto each beam lead and then detonating the explosive to explosively bond the integrated circuits to the substrate. In another embodiment of the invention, the explosive bonding force is applied through a buffer sheet of plastic or metallic material which protects the surface of the substrate from contamination and which, in addition, dampens the shock of the explosion. In yet another embodiment of the invention, metal conductive paths are explosively bonded directly to a ceramic or glass substrate to form a ''''printed circuit pattern.'''' The same techniques are used to manufacture resistors, capacitors, inductors, etc.
The method according to claim 1 wherein said first and said second workpieces comprise metallic workpieces.
Claim 2
Dependent Claim
23 words

Claim 3
Dependent Claim
23 words
The method according to claim 1 wherein said first workpiece comprises a metallic workpiece and said second workpiece comprises a metallized glass workpiece.
Claim 4
Dependent Claim
33 words
The method according to claim 1 comprising the further step of: interposing at least one spacing element between said first and second workpieces to provide a gap through which said accelerAtion may occur.
Claim 5
Dependent Claim
28 words
In a method of explosively bonding a first workpiece to a second workpiece, the improvement comprising the use of a primary explosive to produce the explosive bonding force.
Claim 6
Dependent Claim
29 words
The method according to claim 8 comprising the further step of: maintaining a partial vacuum about said first and said second workpieces, prior to detonation of said primary explosive.
Claim 7
Independent Claim
80 words
A method bonding a first workpiece to a second workpiece, at least one of said workpieces having microscopic dimensions, comprising the steps of: moving said first and second workpieces into juxtaposition to each other; applying a quantity of primary explosive material to an outer surface of at least one of said workpieces, in the region to be bonded; and detonating said explosive material to accelerate at least one of said workpieces towards the other to form an explosive bond therebetween.
Claim 8
Dependent Claim
46 words
The method according to claim 8, said method comprising the further step of: displacing one of said workpieces, with respect to the other, so that an angle is created therebetween, through which angle the workpieces may accelerate towards each other when said explosive material is detonated.
