Problems solved by technology
However, the presence of protruding terminal portions through the bottom of the circuit board can make the process of fitting other components to the bottom of the circuit difficult and imprecise
For example, a spreading device (e.g., a squeegee) used to apply solder paste to the bottom of a circuit board may not adequately compensate for unevenness on the bottom of the circuit board due to protruding terminal portions. flat surface
The applicator may then apply the solder paste unevenly and / or may apply too much solder paste in certain areas, both of which may lead to undesirable behavior of the solder paste (e.g., spillage) when heated
Applying solder paste to both sides of the board prior to mounting the terminals may not be desirable as it may increase the chances of the solder paste being disturbed (e.g. when the terminals are mounted on one side, the solder paste on the other side may be more easily disturbed)

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.
Description
technical field [0001] The present disclosure relates to electrical components, including electrical connectors, electrical terminals and / or circuit boards. Background technique [0002] Conventional electrical terminals can generally be fitted to a circuit board via soldered portions of the terminals of the circuit board. The partial assembly process typically involves inserting at least a portion of the terminal entirely through the circuit board so that the terminal can be soldered to the top and bottom of the circuit board. However, the presence of protruding terminal portions through the bottom of the circuit board can make the process of assembling other components to the bottom of the circuit difficult and imprecise. For example, a spreading device (e.g., a squeegee) used to apply solder paste to the bottom of a circuit board may not adequately compensate for unevenness on the bottom of the circuit board due to protruding terminal portions. flat surface. The applic...
