The substrate used in PCB board
Taking ordinary double-sided panels as an example, the sheet materials generally include FR-4, FR - 1, CEM-1, CEM - 3, сорт., толщина листов составляет 0.2 мм to 3.0mm
The thickness of copper varies from 0.5 унций до 6 унций, all of which have caused a huge price difference in the sheet material;
The difference of the suppliers makes the sheet of uniform specifications have a price difference of tens of yuan per square meter; even the same sheet supplier is divided into several
Species. Кроме того, inks, знаковые чернила, etc., Поэтому различия в материалах приводят к различным ценам.
Second, the production costs of different PCB surface treatments are also very different
Different surface treatments will cause different costs. Such as gold-plated PCB and tin-sprayed PCB board, making shape gongs and die punches,
использование шелковых линий и линии производства сухой пленки будет иметь разные затраты, приводить к диверсификации цен.
Third, the price of PCB is different due to different difficulty
The difficulty of PCB itself will also cause different costs. If you want to look at the circuit on the PCB, such as the density of the wire is thin (in the
4/4mm) or less, цена будет рассчитана отдельно; есть ли бит BGA, etc. There are 1000 holes on both circuit boards, one board hole
If the diameter is greater than 0.6 мм and the hole diameter of the other board is less than 0.6mm, different drilling costs will be formed; for example, the two types of circuit boards
They are the same, Но ширина линии и расстояние между строками разные, one is greater than 0.2 мм, and the other is less than 0.2mm, which will also cause different production
Cost, Потому что процент брака на трудно обработанных плитах выше, стоимость неизбежно увеличится, which will cause the price diversity.
четвёртый, different customer requirements will also cause different prices
The level of customer requirements will directly affect the yield of the board factory. например, a board according to IPC-A-600E, class1 requires 98%
The pass rate, но по требованиям третьего уровня, it may only have a pass rate of 90%, Это привело к различным издержкам на картонный завод, and finally leads to the product
The price changes.
пять, the price diversity caused by different Производители PCB
даже один и тот же продукт, because different manufacturers have different process equipment and technical levels, будут возникать разные затраты.
многие производители предпочитают выпускать позолоченные плиты, так как их технология проста и низкая стоимость. However, Некоторые производители также производят позолоченные.
Waste increases, привести к более высоким издержкам, so they prefer to produce tin-sprayed panels, поэтому их предложение на луженую плиту лучше, чем на золоченую.
низкий.
Six, price differences caused by different payment methods
At present, PCB board manufacturers generally adjust PCB prices according to different payment methods, ranging from 5% to 10%.
превратиться в ценовую разницу.
7. Different regions cause price diversity
At present, in terms of geographical location in China, цена выросла с юга на север, and there are certain differences in prices in different regions, so
Different regions also cause the diversity of prices. How to calculate PCB quotation!
1. Plate cost (different plate cost is different)
2. Drilling costs (the number of holes and the size of the aperture affect the drilling costs)
3. Process cost (different process requirements of the board lead to different process difficulties, and even prices will vary)
4. Artificial water and electricity plus management costs (this cost depends on the cost control of each factory, относительно, Taiwan-funded factories are much lower
country)
