Shenzhen Bo Yun Fa Technology, One-stop Service Provider, Located in Shenzhen, China. We focus on high precision PCB, components sourcing and PCB assembly for worldwide customers. Shenzhen is an international Electronic Industry Innovation Center, with rich component resources, efficient and convenient transportation. You will be surprised by our fast delivery service.  We can deliver PCB and PCBA samples within 24 hours, 4-8 layers PCB in 3-5 working days. Especially, we know how to lower the cost for you while maintaining high quality.


It is highly recommended to use a multilayer quick turn PCB design. First of all, the inner layer of Multilayer PCB is specially designed for switching power supply and ground: The switching power supply is very stable, the characteristic impedance of the power supply circuit is greatly reduced, The total length of wiring is greatly reduced


(1) The switching power supply is very stable

With the continuous improvement of the quick turn PCB manufacturing process, there is no problem that the distance between outgoing lines of our company is equal to or even less than 0.1 mm, which can fully meet most applications. Considering the components and production process of switching power supply, the minimum line spacing of double-sided board is 0.3mm, that of a single panel is 0.5mm, and that of pad to pad, pad to via or via to via is 0.5mm. Our company can easily meet the production requirements, and can control the yield very high, but also achieve a reasonable wiring density and a more economical cost.

(2) The characteristic impedance of the power supply circuit is greatly reduced

To achieve the best signal quality, the design of the internal connection keeps the impedance stable as far as possible in the process of signal transmission. First of all, the stability of the characteristic impedance of quick turn PCB is maintained, and the production of a controllable impedance board becomes more and more important. In addition, the shortest remaining line length, terminal removal and the use of the whole line can also maintain the stability of the instantaneous impedance in signal transmission.

(3) The total length of wiring is greatly reduced

In other words, unnecessary vias should not be used. The power supply and ground pins should be drilled nearby, and the shorter the lead between the holes and the pins, the better, because they will lead to the increase of inductance. At the same time, the power and ground leads should be as thick as possible to reduce the impedance.


In addition, considering the cost, although the cost of multi-layer PCB is higher than that of quick turn PCB when comparing the same area, the cost difference between multi-layer PCB and single-sided PCB is not as high as expected once other factors such as miniaturization of quick turn PCB and convenience of reducing noise are considered. Our products are widely applied in Telecom, Medical, Automotive and Consumer Electronics. Our business network extends far to Asia, Europe, America and Australia. Our magic is reliable quality, competitive prices, on-time delivery, and excellent service!
