Press fit electrical terminal having a solder tab shorter than PCB thickness and method of using same

摘要

A method of assembling a circuit board may include inserting a first electrical terminal into a first side of a circuit board, and applying a second layer of solder paste to a second side of the circuit board, the second side disposed opposite of the first side. The first electrical terminal may include a solder tab, a maximum length of the solder tab may be shorter than a minimum thickness of the circuit board, and if the first electrical terminal is inserted into the circuit board, the solder tab may extend at least partially into the circuit board without extending entirely through the circuit board. One or more electrical terminals with short and/or long solder tabs may be inserted into the second side of the circuit board and/or one or more electrical components may be attached to second side of circuit board.

1. A method of assembling a circuit board, the
inserting a solder tab of a first electrical terminal into a first side of the circuit board; applying a layer of solder paste to a second side of the circuit board, the second side disposed opposite of the first side; and applying an initial layer of solder paste to the first side of the circuit board before inserting the solder tab into the first side of the circuit board, wherein the initial layer of solder paste and the layer of solder paste have different liquidus temperatures; wherein the solder tab extends no further than the second side of the circuit board, wherein the solder tab extends short of the second side of the circuit board, and the first electrical terminal contacts the first side of the circuit board.
