2.54mm Pitch Pin Headers

Applications of 2.54mm Pitch Pin Headers

• Motherboard Connectors

The Motherboard of a computer holds together many of the crucial components such as the central processing unit (CPU), memory and connectors for input and output devices.

• Printer Connectors
• Automotive PC Connectors

Smart, high power automotive PC power supply garners its capabilities from quality pin headers, designed for general purpose battery powered applications. These are manufactured to provide power and to control the motherboards’ switch based on ignition status.

• Battery Connections

Rechargeable battery packs, battery balancers, battery eliminator circuits. Battery connections rely on the ability of the current to pass reliable and solid current. This prevents overheating in the circuit and voltage drop.

• Medical Diagnostic and Monitoring equipment
• Communications: Telecoms and Datacoms
• Industrial and Automotive Control and Test

Mount Type: Through-hole vs Surface Mount

2.54mm pitch pin (male) headers are offered in either Surface-mount or Through-hole mount termination. At one side of this pin header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).

Through-Hole (Poke-In)

• Best used for high-reliability products that require stronger connections between layers.
• Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
• Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
• 2.54mm vertical single row header, 2.54mm vertical dual row header, 2.54mm Elevated single row pin header, 2.54mm Elevated dual row pin Header, 2.54mm Right-angle single row header and 2.54mm Right-angle dual row header are some examples of Scondar products with through-hole mount type.

Surface-Mount

• The most common electronic hardware requirements are SMT.
• Essential in PCB design and manufacturing, having improved the quality and performance of PCBs overall.
• Cost of processing and handling is reduced.
• SMT components can be mounted on both side of the board.
• Ability to fit a high number of small components on a PCB has allowed for much denser, higher performing, and smaller PCBs.
• 2.54mm Right-angle Dual Row pin header, 2.54mm SMT Single row pin header, 2.54mm SMT Dual row pin header and 2.54mm Elevated Dual Row Pin Header are Scondar’s SMT pin headers.

Soldering Temperature for 2.54mm Pitch Pin Headers

Soldering SMT pin connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.

Pin-Type: Vertical (Straight) and Right-Angle

2.54mm pitch headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle male header.

Vertical or Straight Pin (Male) Header Orientation

• One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called “straight” or “vertical”) or.

Right-Angle Pin (Male) Header Orientation

• Parallel to the board’s surface (referred to as “right-angle” pins).

Each of these pin-types have different applications that fit with their specific configuration.

PCB Connector Stacking

Elevated Pin Header Orientation

Elevated pins aka Stacked Pins or Mezzanine are simply stacked pin headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.

Profile Above PCB

This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.

Single, Dual or Multiple Number of Rows

For a 1.0mm straight or vertical male pin header, the standard number of rows that Scondar offers ranges from 1 to 2 rows. However, customization can be available if 3, 4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins while for dual row, the number contacts may vary from 2-80 pins.

Pin Material

The pins of the connector have been designed with copper alloy. With customer’s demand the pins can be made gold plated.

Breakaway design

The pin headers are also equipped with a breakaway design making them fully compatible with their female receptacles.

Custom 2.54mm Pitch Pin Headers

Customizable 2.54 mm pitch pin headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed.

Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.

Tape and Reel Packaging for SMT Components

Scondar’s SMT headers are offered with customizable mating pin lengths, in which each series has multiple number of of circuits, summing up to a thousand individual part number combinations per connector series.

The tape and reel carrier strip ensures that the headers are packaged within accurately sized cavities for its height, width and depth, securing the headers from the environment and maintaining consistent position during transportation.

Scondar also offer a range of custom Tape and reel carrier strip packaging cavities.
