PCB Assembly Cost-6 Ways To Breakdown

Most of the engineers, especially the recruit ask, some common questions such as: From where I can get the economical PCB assembly cost? How can I decrease the PCB assembly cost?


The people who struggle more to get lower price instead of considering the quality of PCB assembly, there is never an inexpensive PCB assembly service, in this case, there will be more chances of project failure due to lower quality of your circuit board. We strongly suggest you get a PCB assembler that provides the best balance between cost, customer service, and assembly quality as well.


To reduce the assembly cost preference is that you have to adjust your circuit design, and then you can choose the right PCB assembler along with excellent services within your budget. 

1、PCB Assembly Cost Composition

As you know that material, specification and the delivery time are main factors of price. Here we are going to discuss some other factors that affect cost composition.

Material Results in Cost Variety:

To the ordinary double panel such as the sheet that has FR-4, CEM-3, the thickness of board 0.6mm - 3.0mm, copper weight 0.5oz - 4oz, they all become a cause of big price difference. There is a definite price difference about conventional thermosetting oil, LPI and solder mask ink.


The Production Process Results in Cost Variety:

Different processes of production may result in different cost. Just like HAL and Gold-plated, a dry film-pattern, a silk screen-pattern as well as the routing and punching.


The difficulty of PCB Results in Cost Variety:

The PCB difficulty also causes different cost even if the material and process are the same. Such as if Two PCB types are 1000 holes, hole diameter is up to 0.6mm for one type of PCB and other is less than 0.6mm, it becomes a cause of different drilling cost. If two PCB are the same, but line trace and width are different than this will also cause different cost.


Customer Requirements Results in Different Costs:

Customer requirement level will affect the manufacturer’s yield directly, such as according to the IPC-A-600E, class1 the PCB's First pass yield is 98%, but according to class 3, it is only 90% that will result in a different cost for the manufacturer.

PCB Manufacturer Results in Different Cost Variety:

Even if the product is the same but because of using different technology and equipment, it will also result in the form of different cost.


PCB Assembly Cost---Factors Need To Consider:

The PCB Assembly cost is one of the most essential things because every designer or engineer really would like to know about the following questions:


How to get a best and complete PCB Assembly quote?


How to find out what price would affect the PCB Assembly cost?

Here we are going to tell you about some critical factors that you need to consider for PCB assembly cost:


2、Important Factors That you Need to Consider for PCB Assembly Cost

Choice of Material:

The material choice is one of a significant factor that affects the price of PCB Assembly Cost. Some essential aspects impact the selection of material:

Reliability of Thermal:

Can the Board perform under a temperature range which is expected to the tasks in question? Some boards required material of higher thermal rating as compared to the standard board.


Reliability of Temperature:

Within a controlled setting can a material withstand expected atmospheric conditions range ignoring the overheating? The PCB is intended for the effective operations of high temperatures and requires a material that can pass these tests easily.


Transfer of Heat:

Will, the board withstands has loads of high intensity without passing an excessive heating level to the adjacent and attached components? The right Material needs to pass this test for uses in question. 


The Single Performance:

Throughout each operating cycle o the given machine, will the material is facilitating uninterrupted electrical signals? Will these signals face a critical temperature's range and some important environmental factors? It concerns with the performance of PCB. 


The Mechanical Properties:

Does this material have contained on a tremendous physical composition to face a possible range of physical stresses? Can the board drop several feet without any breakage?


Quantity of PCB Assembly:

Most of the manufacturer may not have just a minimum requirement of numbers, but it is sure that all of them have a fixed amount to precede an order because the quantity is a factor of extremely crucial. If you place a large order, then most of the manufacturer will offer you a great discount. If you purchase a higher number of PCBs, then you will be charged for the lower cost for each PPCB.


The higher purchase will provide an opportunity to eh manufacturer to make up for the resources which are utilising by them. In this way, the manufacturer can achieve the efficiency of manufacturing and the buyer can achieve an efficiency of cash follow by getting more in little amount.

3、PCB Assembly Cost Breakdown

It is the most important point most engineers want to know. Here we are going to tell you about the most effective ways that help to cut the cost of PCB assembly Cost by giving you the insurance for quality:


Size of the Board:

A panel is one of the most important parts that are used to produce a PCB. Size of the board is another essential factor that affects the cost of PCB. If the board is bigger, the manufacturer will need more material to build it. This point is might straightforward and straight forward for you, but it is not as simple as that.


PCB Assembly Cost.jpg


By depending on specified dimensions, it is probably possible that a board may take less estate's area, but it is higher in its cost. It will be happened due to the overall size of the PCB’s panel that is used in the manufacturing of the board. 


Sometimes one dimension fits the panel better as compared to the other one. Here we will consider two parts with the same total square inches according to per board.  The first board is 2sq.in x 6sq in and second board is 3sq.in x 4sq in variety of the board. Here the cost for the single board will be reduced for the 3sq.in x 4sq.in.


The Number of Layers:

A printed circuits boards for both single and double-sided may cost manufacturer probably the same to produce. But the PCBs that contained on multilayers is different because they add some additional cost in its material and manufacturing process as well. 


Moreover, moving from single to double layer and double to quadruple layers will automatically increase and double up the original price. The price will start to vary when you add more layers into the mix. For example, if you are going from 4 layers to the six layers, it will increase the overall price that can be 25%, but if you are going from 6 layers to the eight layers, then the rate might be increased by 100%. It will depend on the additional material that is needed to create more layers.


The Lead Time:

The price also depends on the lead time; it means how fast you want to get your PCBs. If there is no dealing, the manufacturer will perform their work with their own pace and utilise the resources in different ways that will not become a cause of extra cost for them for the manufacturing of PCBs. For the priority order, the manufacturer needs to complete the task within the given deadline, and they need to put their other project on hold. Because of this reason they need to charge extra cost for manufacturing on an urgent basis.


Choose Best PCB Assembler:

Almost all the service provider gives you a surety to provide a cost-effective service, but it is not enough to get good quality at a reasonable price. First, you should get full awareness for the requirements of your project and budget as well then you have to search for the best PCB assembler. For this, you have to cover the following aspects:



Make sure that the assembler that you are going to choose is certified that will provide you surety for their work. Some important certifications include RoHS, ISO9001, UL, etc.


Equipment Uses:

The assemblers should have up to date equipment that will contribute to the high quality and high efficiency of PCB assembly.


Component Procurement:

Based on our years of experience in the industry of PCB, We can notice that lots of time and money are lost in the manufacturing stage of PC Boards just because of the disjoint relationship between the phases of the process. So to save time and money, we should recommend you to cooperate with the PCB assemblers who are offering components sourcing service to their clients. In this way, you can focus on the improvement and engineering of your project and allow the assembler to do what it is good at, buy a cheap but the high-quality components and then assemble them onto your circuit board.


Bare PCB’s Schematic Design Optimization depending on Low-Cost Concern:

The actual manufacturing of the first step, check whether your circuit can properly be implemented (called DFM check) is very important.  Most of the PCB assemblers are providing a free service of DFM check that helps to reduce the cost without compromising on quality. Four important factors affect the cost of Bare PCBs:


• Layout Count


• Via Tech


• Shape and size


• Surface finish

Prepare a Complete and Effective BOM:

BOM stands for a bill of materials; it is a comprehensive list of items, raw material, components as well as assemblies and sub-assemblies, etc. Preparing a complete BOM to include some important details for PCBs such as the name of the manufacturer, Part number, Reference designator, Description, Quantity, the Case/Package, Top/Bottom, SMT method, Comment/Note, Points/Footprint, BOM level. It is recommended to add the replacement of the components in your BOM because the electronics is developing fast and the parts upgrade rapidly with the old items eliminated.


Complete BOM will allow the manufacturer to quote in two or three days and start production after your confirmation.


Make the Component Sourcing Clear:

If you are a company of small size, then it is challenging for you to schedule your project and control your budget. Here rely on the PCB assembler will make more sense. The Record assembler should have a friendly relationship with the distributors of franchised component for their long term cooperation. They can get your demanded components on the wholesale price that will help you to make a low cost but high-quality PCB Assembly.


Adjust the Order Volume and Lead Time:

Keep your company condition in mind, and according to the volume of your order, select the PCB assembler that can provide services as per your requirements.


However, Different Assemblers have different calculation ways of lead time. So make sure that you know about your assembler lead time.


Don’t Ignore Test:

It may increase some cost but don't forget that we aim to reduce the price without compromising on quality. Testing plays a vital role in contributing to the high quality of your project that will tell us about issues or mistakes in advance.
