In the electronics industry, SMT is inevitable. STM is the process of soldering of components. A placement machine is needed. The placement efficiency need to be high and the failure rate need to be low, which ensures the quality and quick shipment of electronic products. How is the cost of SMT price calculated? Now let PCBA manufacturer SYS Technology to introduce the calculate structure for everyone.
The competition in the SMT industry is now fierce, and the price has dropped a lot compared to previous years. In order to survive, SMT companies provide many discounts to old users in order to stick their customers, and also provide many discounts to attract new users. Generally speaking, the price of SMT includes the following factors.
The main factor affecting the price of SMT: The number of solder joints
The number of solder joints is a decisive factor in the price of SMT. Current SMT quotations are basically calculated based on the number of solder joints. Devices such as small resistors and capacitors are counted as one solder joints. For larger solder joints such as SOT-89, two solder joints may be counted. The more times of cooperation, the cheaper the price; the more number of boards, the cheaper the price.
As long as the SMT factory has enough orders, the machine will be running for 24 hours without stopping. In the past few years, there were also set-up fees or engineering fees. As long as you assembly the boards, no matter how many numbers there are, you will be charged set-up fees or engineering fees according to the times of order. Now it is rare, unless the quantity is very small.
In the early days, the cost of stencil was more expensive. It costs around 100USD to make a stencil. Some SMT manufacturers will also make stencil for their customers, and the fee will be more expensive. SMT manufacturers make stencil now at price around 50USD, they make plastic stencil when there are only few solder joints.
In SMT manufacturers, after the materials are delivered, they must be scheduled up for mounting. If you need them urgently, you need to pay an expedited fee, which is charged according to a fixed amount or a percentage.
