You may not be familiar with FR4 substrate, right? Don't know what it's made of? Or don't know its performance characteristics and standard thickness of FR4 substrate? I think this article will be the best one for you.
You may not be familiar with FR4 substrate, right? Don't know what it's made of? Or don't know its performance characteristics and standard thickness of FR4 substrate? I think this article will be the best one for you. Today I'm going to give you a description of FR4 substrate to help you understand it better.
First of all, what are the material and performance characteristics of FR4 substrate?
FR4 substrate is a laminated sheet made of special electronic cloth impregnated with epoxy phenolic resin and other materials under high temperature and high pressure. It has high mechanical properties and dielectric properties, good heat resistance and moisture resistance, good mechanical processing, etc.
Now what is the density of FR4 substrate?
Actually, the specific value is hard to say as same as the price, because the material and processing means of each manufacturer are different. Of course, its density is also a variable. But the general density ranges from 1.75 to 1.80.
And finally what is the price of standard thickness of FR4 substrate?
In fact, the price of FR4 substrate is definitely not uniform. As long as we find the right manufacturer, I think the price and quality should be reasonable. ZTelec Group has 62 years of time in producing and processing FR4 substrate. It can be said that the experience is very rich; Secondly, the company has a set of processing equipment, it constantly introduces technical personnel. It can be said that the technology is constantly updated; In addition, our processing price is very reasonable. Compared with the same quality of processing, our cost is by no means high; The last point is that we can process according to all drawings and samples, and we can design drawings for customers free of charge. As for the processing price of halogen-free FR4 substrate, you can consult our online customer service. Because the price has a certain range of fluctuation, and the price varies with different specifications and materials.
