A method of interconnecting first and second printed circuit boards (10, 12), comprising the steps of providing a float connector comprising a contact assembly, first and second guide members slidably and flexibly coupled to the contact assembly, and a biasing member between the first and second guide members that biases the first and second guide members away from one another, thereby defining an open position of the connector in which first and second contact ends of contacts of the contact assembly are recessed in the first and second guide members, respectively; installing the first guide member onto the first printed circuit board with the float connector in the open position by inserting one or more alignment features of the first guide member into corresponding one or more alignment holes in the first printed circuit board; after installing the first guide member onto the first printed circuit board, aligning the second guide member with one or more alignment holes in the second printed circuit board; after the step of aligning the second guide member, installing the second guide member onto the second printed circuit board with the float connector in the open position by inserting one or more alignment features of the second guide member into the corresponding one or more alignment holes in the second printed circuit board; characterized in that compressing the first and second printed circuit boards (10, 12) axially toward one another along an axis generally parallel with a longitudinal axis of the contacts and against the bias of the biasing member until the first and second contact ends are exposed outside of the first and second guide members, respectively, and received in corresponding plated holes in the first and second printed circuit boards (10, 12), respectively, for electrical connection thereto. providing a float connector comprising a contact assembly, first and second guide members slidably and flexibly coupled to the contact assembly, and a biasing member between the first and second guide members that biases the first and second guide members away from one another, thereby defining an open position of the connector in which first and second contact ends of contacts of the contact assembly are recessed in the first and second guide members, respectively; installing the first guide member onto the first printed circuit board with the float connector in the open position by inserting one or more alignment features of the first guide member into corresponding one or more alignment holes in the first printed circuit board; after installing the first guide member onto the first printed circuit board, aligning the second guide member with one or more alignment holes in the second printed circuit board; after the step of aligning the second guide member, installing the second guide member onto the second printed circuit board with the float connector in the open position by inserting one or more alignment features of the second guide member into the corresponding one or more alignment holes in the second printed circuit board; characterized in that compressing the first and second printed circuit boards (10, 12) axially toward one another along an axis generally parallel with a longitudinal axis of the contacts and against the bias of the biasing member until the first and second contact ends are exposed outside of the first and second guide members, respectively, and received in corresponding plated holes in the first and second printed circuit boards (10, 12), respectively, for electrical connection thereto.
