1.25 Wafer Connector

A 1.25mm vertical wafer connector wire-to-board configuration refers to a specific type of electrical connection where wires are attached to a vertically oriented wafer connector for connection to a printed circuit board (PCB).

The 1.25mm vertical wafer connector wire-to-board configuration offers a compact, reliable, and space-saving solution for connecting wires to printed circuit boards in electronic devices and equipment. Its vertical orientation and small pitch make it ideal for applications where space is limited, without compromising on performance or reliability. Proper installation and insulation techniques are essential to ensure optimal electrical connections and safety.

Connector pin holder, also known in the industry as header or wafer, is a connector that is mounted on a printed circuit board and needs to be soldered to the circuit pin.

Common connector pin holders are: no cover base (for example: row needle structure), cover base (common wafer type), friction lock type.

The pin holder of the connector belongs to special plastic for high temperature environment, and needs to have high temperature resistance. For example, the needle holder used for surface mount welding shall be welded by reflow welding equipment, and the temperature shall reach about 265°; The other is that the pin type needs to be welded by wave soldering equipment, and the temperature resistance needs to reach about 230°. If the temperature of plastic can not reach the welding process will affect the normal use of structural deformation.

The features of the wafer connectors

 

1. Vertical Wafer Connector:

Pitch: The connector has a pitch of 1.25mm, indicating the spacing between the centers of adjacent contacts.

Orientation: It features a vertical orientation, meaning the connector is mounted perpendicular to the PCB surface.

Contacts: The connector consists of multiple contacts arranged in rows, typically with one row of contacts on each side of the connector.

2. Wire-to-Board Connection:

Wire Attachment: Wires are attached to the connector contacts, typically using methods such as soldering, crimping, or IDC (insulation displacement connection).

Board Mounting: The connector is mounted onto the PCB surface, with the wires extending vertically from the connector to the board.

3. Installation and Assembly:

Soldering: Wires are soldered to the connector contacts using soldering techniques, ensuring a secure and stable connection.

Crimping: Alternatively, wires may be crimped onto the connector contacts using crimping tools for a reliable and quick assembly.

Insulation: Proper insulation techniques must be employed to prevent short circuits and ensure electrical safety.
