Why are kinked pins used in board to board connectors?
Kinked pins (also known as locking leads) are used as a method of fastening a through hole pin header or socket to a PCB prior to soldering. Kinked pins are particularly useful when using tall components and/or wave soldering process that may cause the connector to move out of position before it can be soldered in place.
What happens if there is no pin 1 on a PCB?
In absence of a pin 1 designation on the header, if a designation is missing from the header, the PCB may have a marking indicating orientation (often the solder pad around the hole of pin 1 of a PTH header is square rather than round).
What do vertical and right angle PCB connectors mean?
Defines the orientation which a connector sits on the PCB. Vertical (straight) is 90° to the PCB, right angle (horizontal) is 180° to the PCB. The profile of connectors above the PCB. Vertical connectors denote the stacking profile in parallel PCB applications, right angle connectors denotes height above the PCB.
What are the different types of pin header connectors?
Pin header connectors comprise several different means of connection. Generally, one side is a series of pins which are soldered to a PCB, and they can either be at a right-angle to the PCB surface (usually called “straight”) or parallel to the board’s surface (confusingly referred to as “right-angle” pins).
How are PCB connectors connected to each other?
Through a process called contact. On each connector, there’s a set of metal parts that press together and form a connection. Of course, connectors can’t just make contact with any kind of connector. Each one has its own unique polarity, which means that it can only be connected in one orientation with a particular type of connector.
What are the different types of board to board connectors?
Connector styles. Board to board connectors are manufactured in the following types: Pin header (also known as male header) Elevated pin header (also known as stacked, stacker, mezzanine and PC104 headers) Shrouded header (also known as box header) Socket (also known as female header or receptacle)
