Abstract
Abstract A method for continuously guiding a DIP device throughout its installation on a circuit board wherein the lower parts of the device leads are offset from the plane of the wider upper parts and are guided during installation by guide walls with vertical grooves whose width and spacing complement those of the leads, the walls being in continual contact with the circuit board, and the grooves being aligned with circuit board holes into which the leads are to be inserted.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
203 words
The method of guiding while inserting into a circuit board a dual in-line package device having opposed sets of terminals extending outward from the package and bent to permit insertion of the terminals in a circuit board socket, each of said terminals having a shoulder portion adjacent the package and a leg portion remote from the package and narrower than the shoulder portion, the leg portions of each set being located in a plane distinct from the shoulder portions thereof, comprising the steps of: receiving the device within a guide member having opposed grooved walls outboard of the shoulder portions while constraining each of the individual terminal leg portions on three sides throughout the major extent of the narrow portion of the terminal; locating the guide member and device adjacent a circuit board socket such that the leg portions are aligned with corresponding socket openings; moving the device from its position within the guide member toward the circuit board and inserting the leg portions into the respective socket openings while continuing to constrain the leg portions during said movement; and removing the guide member from its position adjacent the circuit board without spreading said walls while leaving the device mounted in said socket.
Claim 2
Independent Claim
203 words
The method of guiding while inserting into a circuit board a dual in-line package device having opposed sets of terminals extending outward from the package and bent to permit insertion of the terminals in a circuit board socket, each of said terminals having a shoulder portion adjacent the package and a leg portion remote from the package and narrower than the shoulder portion, the leg portions of each set being located in a plane distinct from the shoulder portions thereof, comprising the steps of: receiving the device within a guide member having opposed grooved walls outboard of the shoulder portions while constraining each of the individual terminal leg portions on three sides throughout the major extent of the narrow portion of the terminal; locating the guide member and device adjacent a circuit board socket such that the leg portions are aligned with corresponding socket openings; moving the device from its position within the guide member toward the circuit board and inserting the leg portions into the respective socket openings while continuing to constrain the leg portions during said movement; and removing the guide member from its position adjacent the circuit board without spreading said walls while leaving the device mounted in said socket.
Claim 3
Dependent Claim
56 words
The method of claim 1 wherein the locating step includes positioning the guide member in physical contact with the circuit board socket to minimize the distance for the leg portions to traverse between the constraining grooves and the socket openings in order to reduce the incidence of failure in the insertion of DIP devices in sockets.
Claim 4
Dependent Claim
38 words
The method of claim 1 further including the step of bending the terminals prior to the receiving step into a convfiguration such that the leg portions are in a plane distinct from the plane of the shoulder portions.
Claim 5
Dependent Claim
72 words
The method of claim 3 wherein the shoulder portions of the terminals are bent through a substantially right angle and the bending step comprises bending the leg portions of the terminals into a generally S-shaped configuration at a point near the juncture of the leg portion and the shoulder portion such that the leg portion below the S-shape is substantially parallel to and outwrdly offset from the shoulder portion nearest said juncture.
Claim 6
Dependent Claim
195 words
Apparatus for guiding a dual in-line package device having opposed sets of terminals extending outward from the package and bent to permit insertion of the terminals in a circuit board socket, each of said terminals having a shoulder portion adjacent the package and a leg portion remote from the package and narrower than the shoulder portion, the leg portions of each set beIng located in a plane distinct from the shoulder portions thereof, comprising: a guide member having opposed grooved walls, each of the grooves being spaced to receive the corresponding terminal leg portion and having three sides to constrain the leg portion during movement within the groove and prohibit lateral movement of the leg portion during insertion, the three sides meeting at right angles to each other, the grooves being open at the bottom ends thereof and only wide enough to receive the narrow leg portions of the terminals to the exclusion of the inboard wider shoulder portions thereof, the walls being in respective planes distinct from the shoulder portions of the terminals whose leg portions are contained therein; and the guide member defining a central opening to permit ejection of the device therefrom.
Claim 7
Dependent Claim
195 words
Apparatus for guiding a dual in-line package device having opposed sets of terminals extending outward from the package and bent to permit insertion of the terminals in a circuit board socket, each of said terminals having a shoulder portion adjacent the package and a leg portion remote from the package and narrower than the shoulder portion, the leg portions of each set beIng located in a plane distinct from the shoulder portions thereof, comprising: a guide member having opposed grooved walls, each of the grooves being spaced to receive the corresponding terminal leg portion and having three sides to constrain the leg portion during movement within the groove and prohibit lateral movement of the leg portion during insertion, the three sides meeting at right angles to each other, the grooves being open at the bottom ends thereof and only wide enough to receive the narrow leg portions of the terminals to the exclusion of the inboard wider shoulder portions thereof, the walls being in respective planes distinct from the shoulder portions of the terminals whose leg portions are contained therein; and the guide member defining a central opening to permit ejection of the device therefrom.
Claim 8
Dependent Claim
17 words
Apparatus in accordance with claim 5 wherein the grooves are also open at the upper ends thereof.
Claim 9
Dependent Claim
43 words
Apparatus in accordance with claim 5 further including means for configuring the terminals of a dual in-line package device so that the leg portions thereof are situated in a plane which is distinct from and outboard from the shoulder portions of said terminals.
Claim 10
Dependent Claim
61 words
Apparatus in accordance with claim 7 wherein the configuring means comprises means for bending the leg portion of each terminal into a generally S-shaped configuration at a point near the juncture of the leg portion and the shoulder portion such that the leg portion below the S-shape is substantially parallel to and outwardly offset from the shoulder portion nearest said juncture.
