The Different Types Of PCB Assembly

A PCB Assembly is the last of a four-stage production of printed circuit boards, wherein components are placed to make the boards functional. are provide us your requirements and we create the PCB design. We use two general categories of board assembly, according to technology used and according to the duties performed.

In the technology used category, we are currently using three assembly technologies. One is the old and trusted, through-hole assembly. The second one is the SMT (surface mount technology). The newest in our company is the package-on-package (POP) assembly system.


Through-hole mounting technology (TMT) is the oldest among the three assemblies. It dates back to the first time electronics device was assembled and used. In this assembly process, we drill the printed circuit boards with holes and mount the components through the hole. The TMT PCB assembly may be an obsolete technology but is useful in the production of prototypes and simple PCB. It is still widely used in the assembly industry due to its coat efficiency and the stronger bond of the components to the board.

The Different Types Of PCB Assembly :

On the other hand, in an SMT process, we use surface pads to mount the components on the board. We still drill holes on the boards but the purpose is the placement of screws on the sides or anywhere on the board, depending on the client’s requirements. We place non-conducting materials such as plastic on the holes to prevent the screws from creating electrical reactions.

Pcb fabricationThe newest board assembly is the POP system. Actually, the POP is a development from the standard SMT. This technology makes our assembly process faster, especially for electronics devices that have complex requirements. We stack printed circuit boards on top of another board, one at a time or all at the same time after the first PCB is finished. Although this process requires additional software system and machines, the overall cost of assembly is lesser compared to when we use standard SMT in assembling complex PCBs.

The second type of our PCB assembly is according to the duties performed. We have the full and partial turn-key assembly.

In the full turnkey assembly, we perform everything, from the production of the board up to the assembly point. Just provide us your requirements and we create the PCB design. After designing, we create the prototype and send it to your company for approval. Once approved, we proceed with the production and assembly. The printed circuit boards arrive at your doorstep in good working condition.

In a partial turnkey assembly, we perform the assembly process and you provide us the printed circuit boards and the components. We recommend partial turn-key PCB assembly if you have your own PCB manufacturing. Outsourcing the assembly process is cheaper than establishing your own. You do not have to think of capital and labor requirements. If your company has a growing demand on PCBs, we can help you meet those consumers’ demands.
However, if you do not have PCB manufacturing department, we suggest that you try full turnkey assembly. You do not have to worry anything except to test the final output. Although we have done the testing before we send the PCBs, we encourage that you perform testing once you receive the PCBs. In cases that these boards are defective, send us the defective boards and state the defects found for proper evaluation. As long as the defects are due to the negligence on our part, we replace the defective boards with newer ones.

The PCB assembly has evolved a lot since the first PCBs were out on the market. In order to stay in the competition, we adopt the necessary changes in our company and be the company that people seek when it comes to their PCBs requirements. We uphold the principle of providing quality output to our clients. If you have more questions about how we achieve excellent products, please feel free to contacts us and be one of the many customers who trusted.

The Guide to Backing Types

If you haven’t ordered a custom-made patch yet, you’d probably think it is a waste of time. Well, it really isn’t. In fact, sturdy custom patches are worthwhile investments that will last year after year even with continuous use. Finished embroidered patches are also pieces of art themselves. Each custom design is uniquely conformant with the design specifications of a particular client. Accordingly, every finished custom patch is a work of art being put into action by the specific organization.

patchAll about Backings We’ve discussed the importance of embroidered patches. Now it’s time to turn our attention to an important aspect of patches- the backing. When considering a custom-made patch to be crafted, the backing should be carefully chosen to give the patch the right amount of thickness and support. Now, what exactly is backing and what purpose does it serve for the finished embroidered patch? Let our team at give you an overview of backings and how they can be used to enhance your custom-made patches.

What exactly is a backing?

A backing is a form of stabilizer applied to the wrong side of the patch in order to give support and stability to the newly-made patch. Patch backings come in a variety of materials. The thickness of the finished patch and the method with which it will be transferred to the garment are factors that are considered when deciding on the type of backing to use for the finished patch.

Patch Backing Choices

There are several types of backings to choose from depending on your needs. We at list the most common options here.

• Adhesive or Tape Backing

This is the most widely used backing choice because of its convenience, versatility, and ease of use. Tape backing is a less permanent method that’s easy to apply, but also easily comes off, making it not advisable for long-term use. However, for quick patch changes, tape backing is sufficient enough.

• Iron-On Backing

As the name implies, all you need to attach the patch to your garments is a flat iron. This type of backing is relatively easy to apply as well: just place the patch over the garment, top with a damp towel and hold the flat iron against the patch for a half minute to allow the patch to completely adhere to the garment. Iron-on backing is the backing choice for patches to be used for ceremonial as well as casual clothing.

• Velcro Backing

For patches that requires frequent changing and for multiple patches, Velcro backings comes in handy. This backing type allows for more flexibility and durability. The patches cannot be attached securely to the garments for a long time, though, rendering it a temporary backing material. Velcro backings are commonly seen in military morale patches.

• Plastic Backing

This backing option is usually applied to patches in conjunction with iron-on backing. Plastic backing offers stiffness giving the patch superior shape maintenance even after continued long-term use.

• Button Loop Backing-

The button loop backing option is unique in that it requires no gluing and sewing. This backing utilizes a small loop of thread attached at the wrong side of the patch. The loop thread allows the patch to be hung effortlessly on a uniform button or pin. Scout organizations such as the Boy Scouts of America usually order patches with button loop backing because of its easy and effortless usage and long-lasting hold.

These five backing options are all available at, a dedicated patches online store.

The bottom line: Patches can actually survive without backing if they are intended to be directly sewn to the garment. However, if sewing is not an option, then the best backing type that’ll suit the intended patch usage must be utilized to attach the patch to the garment. With so many options to choose from, customers can never go wrong with the quality work that we at can provide. is a best one shop for all types of patches.
