What Should You Expect to for PCB Assembly Cost?

Introduction

Assembling your circuit board is a complicated process. There are many factors that go into determining the final cost of assembling your PCB, including the complexity of the board and the material used in its fabrication. The price tag for building a PCB can vary widely depending on these factors, but it’s important to know as much as possible about what you’re getting into before you start building your circuit board.

We know that building a PCB assembly from scratch can be expensive, but if you’re not sure what to expect when building your own PCBs, this article will help.

We’ll cover everything from the basics of how much PCB Assembly Cost is to what factors influence how much it might cost for you. We’ll also talk about some things you can do to save money and give you an idea of whether or not it’s worth investing in a PCB assembly line for your business.

Why is PCB Assembly Cost Important?

PCB assembly is an important step in the manufacturing process. It involves placing all of the components onto a circuit board and soldering them in place.

A variety of factors will influence the cost of your PCB assembly. The most important factor is going to be how complex your circuit board design is and how many components are on it.

Another factor that will affect your price is where you plan on having your board assembled. This means that if you want it done locally, then you’re going to pay more than if you were to send it overseas for assembly.

Finally, there are various ways in which you can have your PCBs assembled, including automated methods or manual ones. Automated methods tend to be more expensive than manual ones, but they can also produce higher-quality boards that last longer and work better overall!

Things to Determine PCB Assembly Cost

A variety of factors influence the cost of PCB assembly. The most important are the following:

Quantity

The more printed circuit boards you need, the more it will cost to have them assembled. If you’re only going to need one or two, it might be more cost-effective to pay a little extra for the parts and do it yourself. But if you’re ordering many boards, the cost of assembly will be much less than the cost of buying all of the parts and tools required to do it yourself.

The number of components on each board might also have an impact on the pricing. The more components there are, the longer it will take to assemble each board and the more expensive it will be per unit. The same goes for any complicated design elements—if you have many different layers with small components on each layer, this can drive up your costs by making it harder for the assembler to get everything lined up correctly before soldering everything together.

Quality

Printed circuit boards are the backbone of any electrical project. They’re essentially the framework that allows you to connect all the different parts of your project together, so ensuring quality is important.

The quality of your PCB assembly will determine how long it lasts, how well it performs, and how much it costs. The more robust your PCB assembly is, the longer it will last and the less likely it will be damaged by environmental factors like temperature or humidity. This means that if you want your product to function well over time, then you need a high-quality PCB assembly.

Functionality

When it comes to assembling a printed circuit board, the functioning of your board is critical. If you’re building a PCB for a model rocket, it’s going to be pretty simple: the only thing you really need to do is connect wires from one part of the board to another.

But if you’re building a PCB for an engine control system for a car, the requirements are going to be much more stringent. You’ll need to make sure that all of your components are able to tolerate extreme environments, and that they can withstand shocks and vibrations as well. The more complicated your design, the more expensive it will be to produce.

Lead Time

If you are planning to have your printed circuit boards assembled, lead time is the time between the order being placed and the time the boards are ready to ship. Lead time can vary depending on the manufacturer, but it is typically anywhere from 3-6 weeks.

This can be one of the most expensive factors in your assembly cost because it takes time for a supplier to produce your boards, as well as for them to ship them out. This can cause delays in your project’s timeline if you’re not careful.

PCB Assembly Cost Types

You should be aware of the types of PCB assembly before making a decision about which one is right for your project.

By Assembly Method

Manual, semi-automatic, and fully automated PCB assemblies are the most prevalent. The main difference between these is the degree of automation in their process. The more automated the process, the less labor is involved and the less time it takes to assemble.

Manual PCB assembly requires a lot of human intervention, with each step being done by hand. This method can be very quick and cost-effective if you’re only making one or two boards at a time, but it’s not ideal for mass production or large quantities. It also requires a lot of skill from your assemblers and can be difficult to scale up if you need to make lots of boards fast.

Semi-automated PCB assembly involves a little more automation than manual assembly because it uses machines to perform some tasks, but there are still many steps that require human intervention. This can be a good option if you need more than one board made quickly but don’t have enough volume yet to warrant fully automated production.

Fully automated PCB assembly means that every step in the process is done by machine—no human involvement is required! This allows for high volumes at lower costs compared with other methods because there’s less skill required on behalf of your assemblers.

By Product Type

PCB assembly cost is determined by the product type that you’re building. Many factors influence the cost of PCB assembly, including the number of boards required, the intricacy of your board design, and the materials utilized to make it. There are three main categories of electronic products: consumer electronics, industrial electronics, and medical devices. Consumer electronics include things like cell phones and laptops; industrial electronics can be anything from a washing machine to a water pump; and medical devices are things like pacemakers, defibrillators, and so on.

Each one of these categories has its own unique set of requirements when it comes to assembly processes and materials used in manufacturing. This means that each category has its own unique PCB assembly cost associated with it as well.

By Assembly Option

First of all, you’ll have to consider what type of assembly options you want. The most basic option is ‘bare-board‘ assembly, which involves putting your components together on a bare piece of copper and applying solder. This is pretty much the cheapest option for PCB assembly but will also take longer to complete.

Another option is ‘through-hole’ assembly, which involves putting your components through holes in the PCB and soldering them from the backside. This is still pretty cheap but much faster than the bare-board option because there’s less work involved in getting everything connected (since they’re already in holes).

What to Consider When Estimating PCB Assembly Cost

Some of the most essential factors to consider when determining the cost of a PCB assembly job are:

Manufacturer’s Reputation

One of the most important aspects to consider when estimating PCB assembly cost is manufacturer reputation. You want to work with a company that has a good reputation for quality, efficiency, and customer service. A good way to evaluate a manufacturer’s reputation is by contacting other customers who have worked with the same manufacturer and asking them about their experience.

Turnaround Time

The time it takes to turn around an order depends on the type of PCB assembly that is being produced. For example, if you are looking for a large batch of PCB assemblies that will be used in a small number of products, then they can be assembled relatively quickly and sent back to you quickly as well. However, if your order requires more customization or has a very high volume of units, then it may take longer for them to complete your order.

In any case, it’s important that you plan ahead when requesting an estimate from a manufacturer so that they can give you an accurate turnaround time estimate based on their current workload and schedule.

Assembly Methods

When estimating the cost of a PCB assembly project, there are a few things to consider. The first is the assembly method. There are 4 main types of assembly methods:

Automatic Insertion

Automatic insertion assembly methods are the most common assembly method. They are used for the assembly of large products where the product is not built by hand and the parts are not manually placed.

Automatic insertion methods involve placing an object into a mold, which then injects molten plastic that fills in the gaps between each part. This method is used for simple parts and when the cost of labor is not an issue.

Solder-Bumping

A solder-coated tip is used to apply solder to a component lead, which is subsequently pushed onto a pad on the PCB. This process can be used to attach components with or without soldering paste.

Solder-bumping is commonly used for attaching BGA (ball grid array) substrates to PCBs. It is also used for attaching passive components, such as resistors, capacitors, and inductors.

Leadless

A series of processes that allow for the joining of electronic components without having to use a lead wire. This is typically done through the use of soldering, although other techniques include ultrasonic welding, thermal compression bonding, and adhesive bonding. The main advantage of using leadless assembly methods is that they reduce the amount of material used in manufacturing, which can save money.

In-house Assembly

Type of manufacturing that involves the use of labor and machinery to assemble a product from its component parts. This method is used in industries such as electronics, textiles, hardware, and appliances.

Assembly can be done using hand tools or automated equipment. If the assembly process uses different types of equipment, it is usually done in an assembly line format.

PCB Layers

One of the most essential factors to consider when determining PCB assembly costs is the amount of layers in your PCB. The more layers there are, the more expensive it will be to manufacture. In general, a 3-layer assembly is much less expensive than a 12-layer assembly. However, more layers can make your circuit more versatile and allow for smaller components on the board.

PCB Materials and Components

When estimating the cost of PCB assembly, you must consider the materials and components that will be used in your design. The most common materials are FR-4, which is a glass-reinforced epoxy laminate; copper-clad laminate, which is an epoxy laminate with copper foil adhered to it; and FR-1, which is an unclad fiberglass-reinforced epoxy laminate.

You also have to consider the type of components you will need. For example, if you need a large number of surface-mount devices (SMDs), then your assembly costs will go up because SMDs are more difficult to work with than through-hole parts.

PCB Technology

The type of PCB technology used can make a big difference in how much it costs to get your board made. There are two main types:

SMT

Surface mount technology involves soldering electronic components directly onto the surface of an existing printed circuit board rather than through holes or vias as with traditional through-hole designs. This process can be more expensive than using through-hole assembly because each component requires its own soldering pad on top of expensive prepreg materials that have been laid down in several layers to form a PCB during manufacturing processes such as silk screen printing, lamination or immersion tinning before being etched away leaving just enough copper traces remaining below each printed layer so they can function properly when connected together within their respective groups.

THT

Through-hole technology uses leads that go through holes on the board and connect to the components on the other side. This is the most common design for hobbyists and small businesses. To make it easier to assemble, you can use special tools that help you put all the components in place quickly and accurately.

Design Complexity

This is an essential consideration when determining PCB assembly costs. The more complex the design, the more time it takes to assemble, which increases your costs. For example, a simple PCB with only a few components will be much quicker and easier to assemble than a complex one with many parts.

 

Conclusion

We hope that all of the information in this article has helped you learn about what is involved in the PCB assembly process. And now, armed with this information you can begin to make a more informed decision about where to build your boards, which will help ensure you don’t overspend on this important part of your PCB design process.
