How to calculate pcb assembly manufacturing cost?

Electronic PCB assembly price must be considered in order to successfully evaluate the use of rigid printed circuit boards: these consist not only of the production costs of the pure printed circuit boards, but also eg.

Costs of product development

PCB Design cost

PCB assembly

Components cost

testing and logistics

Overall system optimization is only possible through timely coordination between the developers and the circuit board manufacturer. An essential aspect here is PCB design services cost.

Production Costs of Printed Circuits

Cheap Printed Circuit Boards usually costs around 50 USD. This assumes the most basic manufacturing process, and if you want a super small board, you need to use more advanced and more expensive processes.

Hence, larger boards with few layers are cheaper than smaller boards with multiple layers. Advanced PCB technologies, such as blind and underground driveways, can also be used to further reduce the size of the board.

Hat factors increase PCB board price?

But these technologies will add thousands to your prototyping costs, so only use them if absolutely necessary. Starting with a larger circuit board accomplishes three things. First, it reduces the cost of manufacturing the boards. Second, it reduces the design costs to develop the boards, as a larger board is faster to design and easier to debug. This means fewer engineering hours.

PCB Assembly Costs

For a couple of boards with 30-50 different components, the PCB assembly cost is approximately another $ 350 – $ 8,000. A company called Screaming Circuits is used for assembly (which means soldering all electronic components to PCBs).

Cost of electronic components

In addition to the cost of manufacturing and assembling the board, there is the cost for the electronic components. For most products the cost of components is minimal and is usually less than about one hundred dollars for some boards.

Which is the cheapest PCB board?

Based on the PCB design manual on the basis of the dielectric constant, the materials used to make the PCB foundation and the nature of the construction of electronic circuits on the PCB is for the purpose of transmitting a certain signal or signal processing and transmission.

Understanding the dielectric constant of a PCB is always a mystery and is probably the most obscure source of information for PCB manufacturers when providing it to buyers, which can be confusing as well as applicable. Incorrect design causes many design deviations, which can lead to mistakes when choosing the type of PCB for the product and increase the cost because choosing too safe.

What kind of PCB you should choose?

Choosing the type of PCB (ie choosing the dielectric constant for the circuit design) is becoming more and more difficult today because the frequency of this digital pulse is higher and there is no sign of stopping.

The constant question is whether the common PCB material FR-4 can meet such high frequency requirements, the answer contained in the next section will shed some light on this issue.

Also, have other way for the cost calculation, as below for your reference.

For PCB Assembly cost, let us tell you Pcb assembly calculation has basically unified quotation rules in the industry, including pcb circuit board production cost, components sourcing cost, pcb assembly cost, project cost, PCBA testing fee and subsequent logistics clearance service fee, etc. The PCB manufacturing cost, flying probe test and PCB project cost will be included in the production cost of the printed circuit board. When purchasing components, it is necessary to cover about 5% of the material loss due to disk loading such as resistance and capacitance and the loss of SMT patch; the assembly cost of SMT patch includes SMT and DIP post-welding, which is calculated separately according to the solder joint and process mode of the circuit board; engineering fees are generally charged for small batches of PCBA assembly, including the cost of process documents, steel mesh, SMT rewiring, etc. PCBA assembly testing fees also need to be included, accounting according to the testing time of each PCBA board; in packaging logistics, special packaging materials and three anti-paint need to calculate the cost, in addition, according to the customer's transaction terms such as FOB, need to calculate additional customs declaration logistics and other expenses.

PCBA assembly cost and quote calculation formula:

PCBA assembly cost = PCB Design cost + PCB circuit board cost + PCB testing fee + PCB engineering cost (applicable for small batches) + component procurement cost (partially floating 5%) + SMT/DIP welding cost + PCBA testing cost + assembly engineering cost (for small batch application) + special packaging and logistics expenses (if required by customers)
