Abstract
Abstract In testing electronic devices having leads, difficulties are frequently encountered in transporting the devices to a test position and holding them securely while engaging the leads during testing. These difficulties are overcome in devices having an indentation in the body portion by engaging the indentation with a movable carrier pin. This pin pushes the device against a wall. In this position at least one lead of the device is arranged in a specific orientation with respect to the body portion. When the pin (and thereby the device) moves toward the test station, the lead contracts a ramp in its path. As the device continues to move, the lead travels up the ramp thereby pivoting the device into a position at approximately a right angle to the specific orientation upon the device reaching the top of the ramp. The lead is then engaged by a centering element which insures proper alignment for testing. After this alignment, the leads of the device are pressed by a plunger against the wall. A set of test contacts which are recessed in the wall then move outward from the wall to engage the leads.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
A method of transporting, orienting and testing an electronic component having a body portion, at least one lead extending from the body portion, and an indentation, said method comprising: placing a pin into the indentation of the electronic component when at least one lead is extending approximately vertically downward, thereby holding the component movably against a substantially flat surface having an abutment mounted to said surface; and moving the pin to a test station thereby sliding the component along the surface to contact the vertically downward lead of the component with the abutment to pivot the component about the pin to position the lead which was vertically downward into a substantially horizontal orientation at the test station; and engaging the lead with testing contacts at the test station to perform a test on the component.
Claim 2
Independent Claim
135 words
A method of transporting, orienting and testing an electronic component having a body portion, at least one lead extending from the body portion, and an indentation, said method comprising: placing a pin into the indentation of the electronic component when at least one lead is extending approximately vertically downward, thereby holding the component movably against a substantially flat surface having an abutment mounted to said surface; and moving the pin to a test station thereby sliding the component along the surface to contact the vertically downward lead of the component with the abutment to pivot the component about the pin to position the lead which was vertically downward into a substantially horizontal orientation at the test station; and engaging the lead with testing contacts at the test station to perform a test on the component.
Claim 3
Independent Claim
132 words
A method of testing a light-emitting diode encapsulated in a transparent lens, the lens having an indentation for scattering light emitted from the diode, and at least one lead extending from the diode and through the lens for coupling to external elements, the method comprising: placing a pin into the indentation of the transparent lens to hold the component movably against a substantially flat surface having an abutment mounted to said surface; moving the pin to a test station thereby sliding the diode along the surface to contact at least one lead with the abutment to pivot the lens about the pin to position the lead into a predetermined orientation at the test station; and engaging the lead with testing contacts at the test station to perform a test on the diode.
Claim 4
Independent Claim
132 words
A method of testing a light-emitting diode encapsulated in a transparent lens, the lens having an indentation for scattering light emitted from the diode, and at least one lead extending from the diode and through the lens for coupling to external elements, the method comprising: placing a pin into the indentation of the transparent lens to hold the component movably against a substantially flat surface having an abutment mounted to said surface; moving the pin to a test station thereby sliding the diode along the surface to contact at least one lead with the abutment to pivot the lens about the pin to position the lead into a predetermined orientation at the test station; and engaging the lead with testing contacts at the test station to perform a test on the diode.
Claim 5
Dependent Claim
28 words
The method of claim 2, further comprising pressing the lead against the test contacts of the test station after the lead has been rotated into its predetermined orientation.
Claim 6
Dependent Claim
