Cost of PCB Board Assembly Manufacturing
PCBs are essential to the success of any electronic product. However, estimating the total cost of a board can be a daunting task for many companies, especially when it comes to choosing a new manufacturer. There are several different factors that come into play, and the pricing can vary widely. To help ensure that you’re making the best choice for your business, it’s important to understand the different factors that go into calculating the cost of a pcb board assembly manufacturing.
First, you need to know that the unit cost of your PCBs will depend on the design and specifications of the project. You can also determine the unit cost by comparing the prices of various manufacturers. You can then choose a manufacturer that offers the best price and quality. Ultimately, the price of your boards will reflect the quality of the materials used to make them.
The first step in determining the cost of a pcb is identifying all the unique parts in your Bill of Materials (BOM). This will include both the surface mount and through-hole parts. It’s important to note that the number of through-hole parts will have a greater impact on the unit cost than the number of SMT components.
How to Calculate the Cost of PCB Board Assembly Manufacturing
You’ll also need to determine the total number of solder joints. This includes both the solder pads and IC solder joints. For example, a standard solder pad will count as 1 point, while an IC solder joint will count as 2 points. In addition, if you’re using a high-density interconnect (HDI) fabricator, you may need to add solder paste for additional solder points.
Next, you’ll need to determine the number of traces and pins on your circuit board. This will include both the straight and zigzag traces. The number of traces and pins will influence the overall circuit board size and cost, as well as the complexity of the design. In general, more traces and pins will increase the cost of your board.
Lastly, you’ll need to calculate the total patch points on your circuit board. The number of patch points will impact the overall cost of your pcb, as well as the complexity of the design and the fabrication process.
It’s also important to consider the location of your PCB manufacturer. Generally, it’s best to choose a local PCB manufacturer, as this will minimize costs and lead times. It’s also beneficial to work with a manufacturer that has a complete supply chain and convenient transportation and logistics areas. Lastly, you’ll need to take into account the transaction terms like FOB when calculating the price of your board. By following these steps, you can be confident that you’re getting the best price for your pcb board assembly manufacturing.
