Through Hole PCB Spacers/Standoffs

PCB standoffs&pillars are used to separate a PCB from other components. These standoffs are available in unthreaded through hole or female-female or male-female configurations. This favors a wide range of PCB applications. This enables the components to be well secured together.

What are the features and benefits of circuit board standoffs/pillars?

• Metal pcb spacers&standoffs are suitable for mechanical strength and resistance to high-temperature environments.
• Metal standoffs keep the electricity conductivity, maintaining a circuit
• Versatile and easy to fit
• Secure PCBs into place

How do PCB standoffs fit together?

For circuit board standoffs to get a perfect fit, they must be of the correct size. With the correct size, the standoff is chosen and inserted into the PCB. It is easy to align them with pre-drilled holes in the PCB. A metric screw is then fastened into the thread of the standoff to lock it firmly in place.

The screws can also be released and retightened as required. 

What is the purpose of PCB standoffs/pillars?

• Standoffs’ use spread across various electronic applications for creating spacing between individual PCBs.
• They act as spacers to separate PCB boards from other components.
• They are ideal for use in applications where you need mechanical strength
• The mild steel construction is useful in high-temperature environments
• Applications range from consumer electronics, office machinery, datacoms, and telecommunications equipment.
• They fasten the board securely to the device, ensuring no movement happens when the device is under use.
• PCB standoffs prevent parts from coming into contact with each other. This helps to prevent any shorts from happening to keep the devices safer.

Available PCB standoff styles

Standoffs/pillars come in different styles. They include hexagonal, square, or cylindrical shapes in unthreaded through hole,male-male, female-male, or female-female styles. They manufacture them from various materials like aluminum, brass, nylon, and stainless steel. Standoffs are always plated to meet the specific application requirements.

Through hole Spacers(hollow spacers) are typically small, hollow tubes positioned between the PCB and its surface. The purpose of the spacer’s hollow body is to enable a bolt or screw to pass through it. A spacer creates a clearance gap and will spin until the screw is tightened. Available in various inner diameters from 3.2 to 10,3(I.D.). Nylon66 material Molded Through hole Spacer&Standoff has very good thermal and mechanical properties while machined hollow pcb spacers have better mechanical strength and high temprature performance than platic pcb spacers.

• Female-female standoffs: These fasteners are used in the world of electronic components and hardware space out circuit boards. Female-female standoffs can have exterior knurling as well as swage characteristics. Double female standoffs are fully or partially threaded on each end to enable firm securing. They come in a variety of materials: plastic, steel, stainless steel, and aluminum.
• Male-male standoffs: A double male standoff is a fastener that can have a hexagonal center section that is characterized by external threading on each end. They are useful in circuit boards just like the other styles. They are available in plastic, aluminum, stainless steel, and steel.
• Male-female standoffs: This type positions two objects well while allowing a good amount of space between them. Male-female standoffs can be hexagonal or round. They may have exterior knurling and swage characteristics. They have internal threads on one end and male threads on the other. They come in a variety of materials including stainless steel, plastic, brass, steel, and aluminum.

Hexagonal Insulation Standoffs/Pillars: These Standoffs are hero products of Sinohua industries and these are molded from polyamide and brass threaded insert and designed to be installed by hand and do not require assembly equipment. The hexagonal standoffs are suitable for a wide range of applications and are ideal for use when high mechanical strength is required and provide sturdy, insulated spacing for high power electronic applications. They are made of nylon with brass inserts and are rated UL94 V-2 or UL94 V-0 if necessary.

SMT Spacers from Sinohua industries significantly optimize the assembly process of electromechanical units. Mounting conventional spacers takes a lot of time, SMT Spacersare tailor-made for full automation. Available on reel, they can be positioned very precisely on the PCB. Different designs cover a wide range of applications for fast, strong and safe soldering connections. for high productivity purpose, these SMT spacers are generally packaged by tape&reel. Remarkable benefits of these SMT spacers from Sinohua:

• Fast and precise process
• Instant removable kapton foil
• Strong holding forces and torques
• Highest process reliability

Also,Collar spacers from Sinohua are a two piece application; the pin and the retainer. They are designed to capture the PC board. The combination of the mating parts forms a completely enclosed nylon spacer. The use of a binding head type screw is recommended. Each retainer is used with a specific pin.

Self-retaining spacers snap into the board to ease assembly and maintain spacing even when the screw is removed. Avaialable in many spacing, screw and panel thickness options. they are available in standard and stackable versions.

A PCB standoff/pillars application example

To understand how it works, we look at a perfect standoff example. One such example is the fastening of a motherboard to a metal enclosure.

The male-female standoffs fasten to a pre-drilled metal with ringed screw holes in the motherboard. The other end of the standoff fastens to the enclosure wall. When you mount the standoffs in this way, you prevent short circuits.

How do you configure standoff fasteners?

Since standoffs from Sinohua come in a variety of sizes, styles, and materials, to configure them well can be quite a task. To help configure your standoffs well, read the instructions when you buy them.

Sinohua industries made it easy by making the configuration information available on our website. Users can browse, filter, and download standoffs by material, size, style, diameter, finishing, thread size, and length.

Why use these standoff fasteners?

Unthreaded keyholes and snap top standoff fasteners mount and detach the PCB without the use of tools or hardware. These fasteners are required for:

• Offering reliable attachment
• Providing a secure hold
• Reducing the risk of loose hardware damaging the internal circuit
• Allowing the screwless designs of the subassemblies
• Enabling precise and reliable spacing, mounting, and stacking of boards, panels, or other components

Keyhole types are self-clinching standoff fasteners with gripping teeth for broaching in the PCB. They allow the PCB to quickly slip into place. Using a single-threaded standoff further improves security.

The snap top fasteners from Sinohua use a spring action to hold the boards and panels securely. They allow a quick attachment and removal using a simple snap-off/snap-on operation. The snap top types include SSS, SSA and SSC aluminum, stainless steel, and steel standoffs. see typical diagram below of these snap lock pcb spacers.

Some types are supplied with knurled and round fastener heads that allow closer to edge fastening. The gripping teeth on the end of the fasteners have the capability to clinch into thinner sheets than the standard versions.

Broaching standoffs provide strong reusable threads or thru-holes in a spacer format in non-ductile materials such as printed circuit board, polycarbonate, acrylic, glass epoxy and resin laminate components as well as ductile panels with a maximum hardness of 60HRB.  Featuring an axially knurled shank, the serrations are designed to cut into the panel material as it is installed, resulting in an interference fit that offers good torque-to-turn resistance and pull-out performance. Installation is simple, prepare the specified hole and using a flat punch and appropriate anvil, apply a parallel squeezing force to press the part into the hole. When installing in printed circuit board, broaching standoffs are suitable for use in non-plated holes only.Available in metric thread and thru-hole sizes in electro tin plated steel and A2 stainless steel

These features install the PCBs permanently by squeezing them into properly sized holes.
