4L Hybrid PCB

With the advancement and innovation of technology, the precise requirements for circuit boards are becoming increasingly demanding. They are widely used in various fields, including medical equipment, industrial automation, communication equipment, aircraft, and others. They utilize advanced manufacturing technologies and quality control standards to ensure precision, reliability, and stability. Their advantages include not only their excellent performance but also their strong adaptability. They can be designed in various shapes and sizes to meet different application needs. Additionally, high-precision circuit boards can be customized for production to meet specific customer requirements and needs.

For instance, in the medical equipment field, high-precision circuit boards are used in a variety of medical devices such as heart monitors, blood pressure monitors, blood glucose meters, and more. These devices require high-precision circuit boards to ensure accuracy and reliability, thereby safeguarding patients' health and safety.

For (impedance-controlled) high-frequency PCBs, Multi-CB offers Rogers 4350B material with improved dielectric properties. Rogers-4000 materials are based on ceramics, are more homogeneous in the material mix and thus more reliable in terms of signal integrity.

A hybrid layer buildup of Rogers 4350B and FR4 material combines several advantages. The critical layers are built up with a high-tech Rogers core and then pressed with common FR4 prepreg.

Your advantages with hybrid buildup:

Optimised low loss material properties in the high- frequency layers

1.Lower price due to material mix

2.Time saving, due to high material availability

3.Fixed distance from outer- to reference- layer thanks to thickness- stable Rogers cores

4.Defined layer structure with impedance examples

5.Improved adhesion between the layers, thanks to higher resin content in FR4 prepreg( cf. Rogers/ Rogers construction)

6.Greatly improved mechanical stability compared to a plain Rogers buildup

7.High reliability of the PCBs due to high- quality, process- safe and proven buildups
