How much does PCB assembly cost?
PCB assembly cost drivers =PCB Board Cost +Components Cost + SMT and DIP Cost + PCBA Test Cost + Package Cost
The assembly cost of pcb is a priority for many people when choosing a pcb assembly factory. Many people will choose to use the pcb assembly cost calculator, here FS Technology will explain to you “how to calculate pcb assembly cost” in the form of text.
PCBA Manufacturing Cost
PCB material costs
PCBA Process costs
Different PCBA production processes will cause different costs. For example, gold-plated plates and tin-sprayed plates, gong (milling) plates and beer (punching) plates for making shapes, using silk-screen lines and dry film lines, etc., will form different costs.
Manufacturing difficulty increases PCBA assembly costs
PCB manufacturing time cost
Components cost is the mainly cost in PCBA SMT Processing. The PCBA manufacturer purchases the components according to the BOM. Maybe some manufacturer will give substitute components suggestions to customers to help customers save some cost. And some manufacturers will purchase the components according to the original part number in the BOM to make sure the quality and no mistakes. It depends on customers’ choice.
SMT and DIP Cost
The number of solder pads points is the decisive factor in SMT price. Now the PCB SMT quotation is basically in accordance with the number of solder pads points to calculate, the more solder pads points , the price is higher. The solder pads points are different, the pcba cost is also different. Both SMT and DIP cost are calculated by the solder pads points quantity, but DIP points cost will be higher than SMT points cost.
Surface mount technology (SMT) can save money due to low installation costs and high precision of automation.The PCB DIP soldering will cost more as this process need more manual soldering, so labor cost will be added, and pcb assembly price will be high.
Assembly pcb cost also depends on stencil cost.Stencil is needed in the PCB assembly process to print solder paste on the PCB solder pads, it is a basic tool used in PCB assembly. This cost is usually a one-time cost as long as the manufacturing files have no any change.
If customers need the manufacturer to do extra PCBA programming and function test process, there will be some test cost charged by the manufacturer. The cost is depending on the test process complexity and test time.
Conformal Coating Cost
There are two ways in this link, conformal coating sprayer and manual coating. The conformal coating spraying machine mainly generates the man-hour and material cost of spraying. Manual coating mainly involves labor costs and consumables. If customers’ PCBA has conformal coating requirements, there will be conformal coating cost charged.
On the manufacturing side, large quantities lead to lower assembly costs due to economies of scale. It means that when the product is mass-produced, the unit price per PCB will be greatly reduced. In the long run, increasing the number of printed circuit boards can save cost for companies by avoiding unnecessary one-time costs.
Usually, the manufacturer will arrange manufacturing according to the order placing time. But if customers requires expedited finish the assembly with a short time, then there will be extra expedited fee charged.
Every customer’s PCBA size and requirements are different, so the package ways are always different. Usually the manufacturer will be responsible for packing each product well. But if customers have some special requirements for the package and they need custom packages, then there will be package cost charged.
In Conclusion, PCBA costs are made up by many factors. Any factor will cause different PCBA cost difference, so customers can choose the supplier according to your own requirements.
