An Ultimate Guide to PEM Fabricators and Assemblers

When you need a perfect light solution for you manufacturing needs PEM assembly will be your first choice. Today PEM solutions have become world leaders in the modern fastening technology.

These products have specially designed for some specific purposes. Moreover, they are highly beneficial, like they have long life span and are durable. Basically, they are alternative of the wire threaded insert. In fact, the wire threaded insert had first introduced in 1930 by an aircraft industry. Its main purpose was to use for weaker and lighter materials of aircraft.

Nowadays manufacturers are making use of PEM solutions for lighter materials. They have ability to give you the lighter materials without sacrificing the strength or durability.

These PEM assemblies are extremely helpful in modern automobile industries. So, come with us to know about PEM assembly and its advantages. How it works and about its beneficial applications as well as about 3 main types of PEM assembly?

What is a PEM assembly?

PEM actually stands for Polymer Electrolyte Membrane. This is entirely new and revolutionary product which was first established in 1942. This product actually has solved all problems to find light solutions in some specific conditions. Such as, light solutions have greatly needed in the aircraft industry and in modern automobile industry and many more.

Basically, PEM have designed for the following purposes,

1. In order to easy installation
2. For faster self-clinching.

Furthermore, the extreme quality of self-clinching is highly advantageous for

• Time reduction
• Less labor
• Less weight.

All the above benefits have introduced an entire new world for designers and engineers. Moreover, by using PEM assembly they can actually make a wide variety of thinner metal designs. And it has become possible for the first time only because of PEM.

Its fastener self-clinching quality provides the designers easy load-carrying threads in sheets of metal which are very thin to tap. Furthermore, PEM is also very beneficial for electronic designers. Because they can use it for several products in the Printed Circuit Board assembly. Because there is a great need to joint in the very small holes with the help of PEM.

What are the main parts of a PEM assembly?

The PEM cells has actually made by using many layers of several different materials. Moreover, the main parts of a PEM assembly have the following essential parts. Such as,

• (MEA)
• The catalyst layers
• GDLs

The Membrane Electrode Assembly (MEA):

As we have described that MEA or Membrane Electrode Assembly is the core and heart of the PEM. Moreover,

• The membrane
• Catalyst layers (like, cathode and anode)
• Diffusion media

All these media gather and forms the membrane electrode assembly of the PEM.

The catalyst layers:

Basically, the catalyst layer has further two layers which have added on the both of the sides of a membrane.

The layer of anode on one side of the membrane. While the layer of cathode on the other side of membrane. Additionally, these traditional catalyst layers of PEM assembly also consist of platinum particles with nanometer size.

Gas Diffusion Layers (GDLs):

The Gas Diffusion Layers (GDLs) stays at the exterior side of the catalyst layers. The GDLs also help to transport of reactants inside the catalyst layer. Moreover, it also helps to remove the water of the product.

What are 3 main types of PEM assembly?

In fact, there are several kinds of PEM fasteners. Furthermore, most of the applications generally need only one, from these three common types. For example, these three main and highly beneficial types of PEM assembly are:

1. The PEM Self-Clinching Studs
2. PEM Self-Clinching Nuts
3. PEM Self-Clinching Standoffs.

Furthermore, today designers have also introduced numerous innovative products like,

• Rangle right angle threaded fasteners
• Flush rivets
• Snaptop standoffs (ideal for mounting PCBs in order to chassis)

Actually, there is an inclusive range of PEM assembly for electronics designers. And a huge range of mount products which is extremely helpful for PCB assembly.

1.      PEM Self-Clinching Studs:

The Self-Clinching Studs have designed to use in very pliant and ductile metals such as,

• Stainless steel
• Steel
• Aluminum, etc.

These are ideal to use in all heavy-duty application programs.

2.      PEM Self-Clinching Nuts:

Basically, the PEM Self-Clinching nuts are very cost efficient. Moreover, they provide a low-price process in order to install imperial and metric threads in almost all kinds of,

1. Cast Metal
2. Sheet.

In fact, these nuts give more advantages in comparison to rivet nuts. These river nuts have also known as Hank bushes or may be river bushes. By comparing rivet nuts with PEM assembly self-clinch, you will get that PEM self-clinch provide very lower back side knob.

Moreover, it also has ability to improve torque in order to rotate characteristics. Furthermore, when you try to make a comparison between rivet bushes and PEM self-clinch nuts. Then you find that PEM self-clinch nuts have ability to make better performance for,

1. Push out
2. Torque to turn.

3.      PEM Self-Clinching Standoffs:

The PEM Self-Clinching Standoffs have ability to offer very simple and rapid solution in order to mount the components like,

• Circuit boards
• Touch pads
• Control panels
• And many other items inside the metal chassis, etc.

These are the best type of PEM assembly and can provide reliable solution to sheet metals. Actually, these standoffs are very beneficial and you can install them into several different varieties of ductile metals, for example,

• Steel
• Stainless steel

Moreover, they have also designed in the version of open and close end. They mostly come in the size range of M1.0 to M5.

What are popular applications of PEM assembly?

Today in this highly innovative and progressive era several kinds of PEM are rapidly using in all areas. Several different types of PEM like,

• Studs
• Spacers
• Nuts
• Standoffs
• And many other components have used by all the industries around the world.

These popular types of PEM assembly are extremely advantageous. So, all the major manufacturers and producers such as,

• Automobiles
• Spacecraft
• Industrial and electronic equipment and appliances
• Communications systems
• Farm machinery and transportation equipment
• Furniture
• Vending machines
• And aircrafts.

What are benefits of PEM assembly?

There are several kinds of PEM assemblies which are highly beneficial in all modern applications.

In automotive industry:

Basically, if we deeply peep into the automotive industry they are almost in all parts. For example,

• Bumpers
• Airbags
• Steering components
• Brake systems
• Fluid carrying components
• Transmission components
• Anti-vibration requirements and so on.

In the modern electronics:

Moreover, PEM assembly is also beneficial in the field of modern electronics. As you know that modern electronics are totally depending on the PCB boards. The PCB boards use these modern PEM assemblies to mount all the essential components on the boards.

Only these special kinds of PEM can truly mount the components on the circuit boards. Because they are best to use on thin metal sheets. Hence, by using these latest PEM assemblies, PCBs of complex electronic designs have become possible to mount.

Furthermore, these nuts, studs and standouts have extreme importance to design,

• Scooters and Bicycles
• Utility Vehicles,
• Stationary Power Applications and many more

Conclusion:

Hence, all kinds of modern PEM assembly are highly important and advantageous in all latest devices. However, they are cost effective and very easy to install. Consequently, the installation of complex hardware is only become possible because of these PEM assemblies. They are useful even when loose nuts and hardware are not possibly to use.
