Abstract

Abstract A programmable pad printer which responds to an input signal by selecting one of a plurality of marks for transfer to a semiconductor. The input signal is provided to the printer from an external source, such as a semiconductor tester. The appropriate mark is then presented to an opening in a housing by rotating a disc containing the plurality of marks. A print head picks up the mark from the disc and transfers it to the semiconductor.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 197 words
A programmable pad printer comprising: programmable selecting means for selecting a designated mark from a plurality of marks; ink means for supplying ink to said programmable selecting means; a device to be marked; printing means for transferring said designated mark from said programmable selecting means to said device; wherein said programmable selecting means comprises: a mark containing device having a surface containing a plurality of marks thereon; first driving means for driving said mark containing device; control means for controlling said first driving means; and wiping means for wiping an excess of ink from said mark containing device; wherein said printing means comprises: a print head; and second driving means for driving said print head between said programmable selecting means and said device; wherein said second driving means comprises: a shaft having a first end coupled to said print head and a second end; a slide defining an opening therein through which said shaft is disposed; a cam being coupled to said second end of said shaft; a pin extending from said cam opposite said shaft; a cam guide block defining an opening in which said pin is slideably disposed; and a motor coupled to said slide.
Claim 2
Dependent Claim 197 words
A programmable pad printer comprising: programmable selecting means for selecting a designated mark from a plurality of marks; ink means for supplying ink to said programmable selecting means; a device to be marked; printing means for transferring said designated mark from said programmable selecting means to said device; wherein said programmable selecting means comprises: a mark containing device having a surface containing a plurality of marks thereon; first driving means for driving said mark containing device; control means for controlling said first driving means; and wiping means for wiping an excess of ink from said mark containing device; wherein said printing means comprises: a print head; and second driving means for driving said print head between said programmable selecting means and said device; wherein said second driving means comprises: a shaft having a first end coupled to said print head and a second end; a slide defining an opening therein through which said shaft is disposed; a cam being coupled to said second end of said shaft; a pin extending from said cam opposite said shaft; a cam guide block defining an opening in which said pin is slideably disposed; and a motor coupled to said slide.
Claim 3
Dependent Claim 39 words
The programmable pad printer of claim 1 wherein said second driving means further comprises: disc coupled to said motor; and a tie bar having a first end coupled to said slide and a second end coupled to said disc.
Claim 4
Dependent Claim 168 words
A programmable pad printer comprising: a first disc having a plurality of marks thereon; first driving means for rotating said first disc; control means for controlling said first driving means; ink means for supplying ink to said first disc; wiping means for wiping an excess of ink from said first disc; a device to be marked; printing means for transferring a designated mark from said first disc to said device, wherein said printing means comprises; a print head; and second driving means for driving said print head between said first disc and said device, wherein said second driving means comprises: a shaft having a first end coupled to said print head and a second end; a slide defining an opening therein through which said shaft is disposed; a cam being coupled to said second end of said shaft; a pin extending from said cam opposite said shaft; a cam guide block defining an opening in which said pin is slideably disposed; and a motor coupled to said slide.
Claim 5
Dependent Claim 168 words
A programmable pad printer comprising: a first disc having a plurality of marks thereon; first driving means for rotating said first disc; control means for controlling said first driving means; ink means for supplying ink to said first disc; wiping means for wiping an excess of ink from said first disc; a device to be marked; printing means for transferring a designated mark from said first disc to said device, wherein said printing means comprises; a print head; and second driving means for driving said print head between said first disc and said device, wherein said second driving means comprises: a shaft having a first end coupled to said print head and a second end; a slide defining an opening therein through which said shaft is disposed; a cam being coupled to said second end of said shaft; a pin extending from said cam opposite said shaft; a cam guide block defining an opening in which said pin is slideably disposed; and a motor coupled to said slide.
