After completing your PCB design, the next step is to choose the right PCB supplier to bring your design to life.

So as a first step, it is crucial to request a PCB quote. To get an accurate quote, be sure to provide your PCB supplier with relevant information about your project.

In general, a PCB assembly service quote contains the following components.

PCB assembly service quote

In simple terms, a standard PCB assembly service quote contains two parts, one is the cost of manufacturing the board, and the second is the price of PCB assembly.

Before requesting an accurate quote, you should provide as much of this important information as possible to ensure that the price and run time estimates:

• PCB material
• Number of layers
• Size
• Number of square meters of holes
• Alignment width
• Copper layer
• BOM, etc.

Documents required for PCB assembly quotation

Accurate quotation depends on the availability of the following documents.

Bare board printing or manufacturing drawings

It provides mainly the following information.

• Board thickness
• Number of holes
• Dimensions, etc

In addition to this, you will need to provide Gerber files, preferably in 274-x format.

Bill of materials

BOM (Bill of materials) is another important document, the more detailed it is, the better for the PCB supplier to estimate the price. The BOM sheet mainly contains information such as part description, number, reference mark, etc.

Assembly print

With assembly printing, information about the location of the parts can be conveyed.

Supplier list

Ideally a list of approved suppliers and the manufacturer’s part number can be provided.

Information often missed when requesting a quote for PCB assembly

The following is some of the information that is often omitted

Stacking

Include the number of layers, thickness, and details related to the lamination

Solder resist

Soldermask type

Impedance

For high-speed PCB manufacturing, impedance details are essential

Depanelization method

The size and location of the cutout is essential to get an accurate quote for PCB assembly

Silkscreen

Silkscreen files and color selection are also essential details

Surface finish

The type of surface finish has a significant impact on the cost

The main factors affecting the cost of PCB assembly

Mounting technology

The use of SMT (surface mount technology) or through-hole assembly will affect the cost. Compared to through-hole assembly surface mount technology is faster and more automated.

Number of layers

The cost of assembling multi-layer PCBs usually requires higher technology, so the cost is also higher.

Surface finish

As mentioned earlier, the choice of surface finish has a significant impact on cost. Some surface finishes have longer shelf life and higher cost.

Delivery time

Usually delivery time and PCB assembly cost is inversely proportional

Shipping costs

High volume PCB production means more packaging, more volume, and more shipping costs.
