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 a 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 the 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.
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.
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 between conventional thermosetting oil, LPI, and solder mask ink.
Different production processes may result in different costs, just like HAL and Gold-plated, a dry film-pattern, a silk screen-pattern, and the routing and punching.
The PCB difficulty also causes different costs, even if the material and process are the same. If two PCB types are 1000 holes, the hole diameter is up to 0.6mm for one type of PCB, and the other is less than 0.6mm, it becomes a cause of different drilling costs. If two PCB are the same, but line trace and width are different, this will also cause different costs.
Customer requirement level will affect the manufacturer’s yield directly. According to the IPC-A-600E class1, the PCB’s First pass yield is 98%, but according to class 3, it is only 90%, resulting in a different cost for the manufacturer.
Even if the product is the same, it will also result in different costs because of using different technology and equipment.
The PCB Assembly cost is one of the essential things because every designer or engineer really would like to know about the following questions:
Important Factors That you Need to Consider for PCB Assembly Cost
The material choice is one of the significant factors that affect the price of Bill Of Materials (BOM) of a PCB get fitted onto a board. PCB Assembly Cost. Some essential aspects impact the selection of material:
Can the Board perform under a temperature range that is expected to the tasks in question? Some boards required material of higher thermal rating as compared to the standard board.
Within a controlled setting, can a material withstand expected atmospheric conditions range ignoring the overheating? The PCB is intended for high temperatures’ effective operations and requires a material that can pass these tests easily.
Will, the board withstands, have 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.
Throughout each operating cycle o the given machine, will the material is facilitating uninterrupted electrical signals? Will these signals face a critical temperature range and some important environmental factors? It concerns the performance of the PCB.
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?
Most of the manufacturers may not have just a minimum requirement of numbers, but, surely, they have a fixed amount to precede an order because the quantity is extremely crucial. If you place a large order, then most of the manufacturers will offer you a great discount. If you purchase a higher number of PCBs, you will be charged for the lower cost for each PPCB.
The higher purchase will allow eh manufacturer to make up for the resources which are utilizing 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.
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 quality insurance:
A panel is one of the most important parts that are used to produce a PCB. The 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 straightforward for you, but it is not as simple as that.
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 used in the board’s manufacturing.
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 the second board is 3sq.in x 4sq in a variety of the board. Here, the single board’s cost will be reduced for the 3sq.in x 4sq.in.
A printed circuits boards for both single and double-sided may cost the manufacturer probably the same to produce. But the PCBs that are contained on multilayers are different because they add some additional cost in its material and manufacturing process.
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 six layers, it will increase the overall price that can be 25%, but if you are going from 6 layers to eight layers, the rate might increase by 100%. It will depend on the additional material that is needed to create more layers.
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 at their own pace and utilize the resources in different ways that will not cause the extra cost for them to manufacture PCBs. For the priority order, the manufacturer needs to complete the task within the given deadline. They need to put their other project on hold because they need to charge extra manufacturing costs on an urgent basis.
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 of your project’s requirements and budget as well then you have to search for the best PCB assembler. For this, you have to cover the following aspects:
Ensure that the assembler you are going to choose is certified to provide you surety for their work. Some important certifications include RoHS, ISO9001, UL, etc.
The assemblers should have up to date equipment that will contribute to the high quality and high efficiency of PCB assembly.
Based on our years of experience in the PCB industry, 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. To save time and money, we should recommend cooperating with the PCB assemblers who offer components sourcing services to their clients. In this way, you can focus on improving and engineering your project and allowing the assembler to do what it is good at, buy cheap but high-quality components and then assemble them onto your circuit board.
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
BOM stands for a bill of materials; it is a comprehensive list of items, raw material, components, assemblies, sub-assemblies, etc. Preparing a complete BOM to include some important details for PCBs such as the manufacturer’s name, Part number, Reference designator, Description, Quantity, the Case/Package, Top/Bottom, SMT method, Comment/Note, Points/Footprint, BOM level. It is recommended to add your BOM components’ replacement because the electronics are 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.
If you are a small size company, 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 franchised distributors for their long-term cooperation. They can get your demanded components at the wholesale price that will help you to make a low-cost but high-quality PCB Assembly.
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.
It may increase some costs but don’t forget that we aim to reduce the price without compromising quality. Testing plays a vital role in contributing to your project’s high quality that will tell us about issues or mistakes in advance.
