turn to for cheap PCB manufacturing

How can I reduce my PCB price?

custom pcb cost fabrication factors affecting pcb cost
1. Substrate used for PCB
Take cheap custom pcb fabrication as an example. The sheet materials generally include FR-4 Rogers PCB, FR-1, ARLON PCB, CEM-3, etc. The thickness of the board varies from 0.2mm to 3.0mm, and the thickness of copper varies from 0.5 ounces to 6 ounces. , All of these have caused huge differences in custom circuit board cost manufacturing in terms of sheet material; differences in sheet material suppliers make a price difference of tens of yuan per square meter for sheets of uniform specifications; even the same sheet material supplier is divided into several Species. In addition, inks, character inks, etc., so the difference in materials causes the price diversity.
2. The production cost of PCB surface treatment is also very different
Different surface treatments will cause different costs. For example, gold-plated PCB and Heavy copper board, the production of gongs and die punching, the use of silk-printed lines and dry film lines, etc. will cause different costs, resulting in a variety of prices.
Third, the price of PCB is different due to different difficulty
The difficulty of PCB itself will also cause different costs. Because of the higher scrap rate of difficult boards, the cost will inevitably increase, which will result in price diversity.
Fourth, different customer requirements will also cause different prices
5. The price difference caused by different payment methods.
