- The cost of resin is not so high
- The resin sticks to the copper strongly. That’s why it is a good option for the impregnation process of other materials.
- The decomposition temperature of these resin materials is high. That means they affect the chemical properties of the PCB.
- Their dissolving rate is high in safe solvents.
- Resins develop the durability of CEM1 PCB.
- You can turn the resin into a flame-retardant material.
Which Is Better Between FR-4 And CEM1 PCB?
A comparative analysis between FR-4 and CEM1 PCB is described here for your convenience.
Coefficient of thermal expansion
CEM1 PCB offers a more effective coefficient of thermal expansion than FR-4 materials. That’s why CEM1 can tolerate thermal pressure efficiently.
CEM1 delivers better performance than FR-4 materials at a significantly cheap rate. These materials decrease the burden of production cost to a great extent.
Composite epoxy materials are the best choice for the PCB design having a single layer. On the other hand, FR-4 materials are applicable in both multilayer and single-layer designs.
But, CEM1 is a better option for single-sided design topology. This happens due to its affordable price and simplicity of design.
Usually, CEM1 PCB makes the device weight low compared to the FR-4 PCB materials. This happens because of its single-layer design technology.
CEM1 always can’t provide effective dielectric characteristics as FR-4 materials. So, its robustness is comparatively lower than FR-4. But, these PCB materials are useful for numerous electronic devices.
How Does Rigid CEM1 PCB Ensure Physical Stability?
CEM1 materials are reliable for the rigid PCB. This PCB does not permit changing its shape after the completion of the production. Rigid CEM1 PCB delivers the necessary physical stability to the devices.
This inflexible PCB is composed of epoxy resins, paper cellulose with fiberglass laminate. This combination renders tremendous mechanical endurance. Its physical resistance against external forces is highly impressive.
Rigid CEM1 PCB
Besides, there is a well-designed way for signal transmission. It improves the impedance control of the rigid PCB. The most noteworthy thing is that you don’t require a high cost to experience this stable performance.
Is CEM1 PCB Compatible With Multilayer Design?
No. CEM1 PCB is only compatible with the single-layer design technology. CEM1 material is a perfect combination of a couple of glass fiber layers. These layers are placed between the cellulose materials.
Single-sided CEM1 PCB
Then, fiber glasses are impregnated with the resin that produces a single layer of CEM1 PCB. That means the formation of the PCB materials does not allow it to be compatible with the multilayer PCB design.
What Is The Rating Of CEM1 PCB In The Ul94 Standard?
CEM1 PCB gains the V-0 rating in the UL 94 standard. This is the most desired rating among the six categories of this reliable standard. This rating refers to the following matters-
