Grande Electronics specialized in providing all in one PCBA electronic manufacturing services, including PCB Layout, Components Procurement, PCB Fabrication, PCB Assembly, Functional Test, Final Box Build, etc as well as high-density circuit boards Design prototype service.
The Pros of high-density circuit board design Prototype:
1. The same product PCB design can reduce the number layers of support plate, increase density and reduce cost.
2. Increasing the routing density and using tiny-hole fine trace to increase the circuit capacity per unit area so that which can meet the assembly requirements of high-density contact components and facilitate the use of advanced structures.
3. The use of tiny-hole interconnection can shorten the contact distance, reduce signal reflection, and crosstalk between lines, and the components also have better electrical performance and signal accuracy.
4. The structure adopts a thinner dielectric thickness, and the potential inductance is relatively low.
5. The tiny-hole has a low aspect ratio, and the signal transmission reliability is higher than that of the general through-hole.
6. The micro-hole technology allows the carrier PCB design to shorten the distance between grounding and signal layers, thereby improving radio frequency/electromagnetic wave/electrostatic discharge (RFI/EMI/ESD) interference. The number of grounding wires can be increased to prevent components from being damaged by instantaneous discharge caused by static electricity accumulation.
7. Tiny-holes can increase the flexibility of circuit configuration and make circuit PCB design easier. Modern popular electronic products must not only have the characteristics of mobility and power saving, but also have no burden to wear, beautiful appearance, of course, the most important thing is the price is affordable and can be replaced with fashion.
