Explore Our Range of High-Quality Materials for All Your PCB Needs
Selecting the right PCB material is very important when it comes to the functionality, and durability of the PCBs no matter the application. At UnityPCB we offer various premium circuit board materials to fabricate PCBs. Our engineers will recommend the appropriate material for your project given the project needs to make sure your project is of high standard and quality.
According to three different classification standards, the substrate materials we provide are listed as follows:
| Classified by | Materials | Features |
| Reinforced materials | Paper substrate (FR-3) | Cost-effective, easy processing, lower thermal stability |
| Epoxy fiberglass cloth substrate (FR-4, FR-5) | High strength and durability, good electrical insulation | |
| Composite substrate (CEM-1, CEM-3) | Cost-effective, moderate thermal and mechanical properties | |
| HDI board (RCC) | High density and precision, improved signal integrity, flexible design capabilities | |
| FPC board | Flexibility and bendability, lightweight and thin, enhanced durability | |
| Special substrate (metal substrate, ceramic substrate, thermoplastic substrate) | Excellent heat dissipation, high thermal conductivity, enhanced mechanical strength | |
| Resin types | Phenolic resin board | Inexpensive, good insulation properties |
| Epoxy resin board | Excellent electrical and mechanical properties, resistant to moisture absorption | |
| Polyester resin board | Less expensive than epoxy resin, good electrical and mechanical properties | |
| BT resin board | Heat resistance up to 260°C, low moisture absorption, high dimensional stability | |
| PI resin board | Exceptional heat resistance up to 350°C, low dielectric constant | |
| Flame retardant properties | Flame retardant type | Meets stringent flammability standards and regulations, such as UL 94 V-0 |
| Non-flame retardant type | Does not contain any flame retardant additives and is not designed to resist or inhibit the spread of fire. |
This will involve a project-specific consultation where we will advise you on the most appropriate PCB materials based on your project’s design specifications and performance threshold.
At UnityPCB, all PCB materials are inspected and tested to ensure their quality before use, thus guaranteeing that the end products will be high-quality and perform optimally.
We provide comprehensive supply chain management for PCB materials, ensuring reliable inventory control and timely delivery through strategic manufacturer partnerships.
Leveraging our long-term cooperation with reliable material suppliers, we can ensure the steady supply of high quality circuit board materials.
We maintain rigorous quality control measures to ensure that the PCB materials supplied meet the highest industry standards and specifications.
UnityPCB offers a wide array of PCB materials such as FR4, RCC, CEM-1, ceramic, etc., which enables us to meet varied applications needs.
From choosing the materials to supporting your project after the creation of the part,our team will help you navigate every stage of the project to completion.
Such factors are application/environmental constraints, electrical parameters, mechanical strength, thermal characteristics, fire protection, and cost factors.
Important thermal properties include the glass transition temperature (Tg), coefficient of thermal expansion (CTE), and thermal conductivity.
FR-4 is one of the most common types of PCB materials, but we also supply polyimide, ceramic-filled laminates, high-temperature materials, metal core, flexible PCBs, and many other materials that are useful for RF microwave applications.
Some materials require special drilling or plating processes, while others may be more difficult to etch or drill. Material properties also affect the number of layers and design complexity that can be achieved.
Yes, there are lead-free and halogen-free materials that comply with environmental regulations such as RoHS (Restriction of Hazardous Substances).
