Hello everybody,

Today we talk about high frequency circuit board built on Wangling's F4B substrates.

F4B series high frequency materials are Wangling's products of PTFE woven glass fabric. Today, we'll learn the woven glass fabric with ceramic filler: F4BTM-1/2. It's widely used in navigation, radar, satellite communication, 4G, 5G communications etc. with advantages in price and stableness in quality.

F4BTM-1/2 has wide range of dielectric constant (DK) 2.55 to 10.2, and wide laminate thickness, 0.254mm to 10.0mm. Here I list them in the table and keep 3 seconds, you can make a screenshot for the purpose of learning.

OK. copper weight with half ounces, 1 ounce and 2 ounces are available.

Let's see our PCB capability on F4BTM-1/2.

We can provide you with single sided board, double sided board, multilayer board and hybrid types with FR-4.

The common color of solder mask is green, black or no color used.

The surface finish usually used is bare copper (no finish), Hot Air Soldering Level (HASL), immersion gold and immersion silver etc.

We can provide you with prototype, small batches and volume production services.

Should you have any questions, please feel free to contact us.

Thank you for your watching.
