    Many factors make up the price of PCB prototypes. Even veterans of electronics manufacturers have a hard time figuring out what to buy. The purchases just started can only be compared with the quotations made in the past. If you are new to the industry, if you do not understand the factors that make up the price of PCBs, it is difficult to quote a standard price.
    Which parts of the sample PCB quote are composed of
    Here are mainly described the various technical factors that make up the PCB price of the model, and other factors that affect the cost of the PCB board are not explained one by one, such as the region of the board manufacturer, the process expertise of the board manufacturer, and the PCB manufacturer. Role and quality positioning, etc.
    1. Is it Urgent
    The proofing time is relatively tight. If the general single-sided and double-sided prototype is to be delivered within 24 hours, it may cost about 45 $.
    2.Invoice Cost
    Some electronics factories have very formal financial procedures, so each purchased item needs to provide an invoice. Everyone knows very well that ticketing is taxable, so circuit board manufacturers generally add this to the price. Invoice taxes.
    3. Courier Fees
    Generally, companies with long-term cooperation and relatively close areas will have free delivery by drivers, while those with long-distance areas and small cooperation amounts will use express delivery methods. Ordinary courier services generally do not charge, and when SF Express is relatively expensive, freight may be charged. The specific freight price can be found on the website of the courier company.
    4. Flying Probe Test Cost
    Generally, the number of samples is small and the data is simple. Most of them are not flying test or all of them are free. When the data is very complicated and a large number will occupy the circuit board manufacturer’s machine, the flying test will also charge.
    5. Surface Treatment Costs
    Due to the different circuit boards, the cost of surface treatment is very different. For example, the gold of immersion gold is very expensive, so the immersion gold process board is generally about 25 $ more expensive than the circuit board of the ordinary tin spray process.
    6. Ink Cost
    In the production of PCBs, most of the solder resist character inks are green oil white and ordinary inks. If there are special needs during board production and the order quantity is very small, manufacturers will waste a lot of inks, so non-green oil white characters are used Price may increase by 10 $
    7. Board Fee
    This is mainly the size of the PCB board. The larger the size of the PCB board, the more PCB substrates are consumed. The PCB substrate is the largest raw material expenditure in the production of circuit boards. Therefore, the general price calculation is based on the size multiplied by the fixed amount. Board fee coefficient.

    Other costs such as fixed engineering costs and film costs, the price base of film costs is constant, but the more layers of circuit boards, the more film sheets are consumed, so the cost will also be higher, and the engineering costs mainly involve To the processing of engineering data and the production of production tools, the longer the board with a large number of layers, the longer the engineering fee will be charged, but this fee is generally fixed.
