Main Features of 3 oz Copper PCB
The following are the specifications of a 3 oz Copper PCB:
- Reinforcing Material – It is made of glass fiber and wood pulp. In addition, it has a copper clad on both sides of the board.
- Heat Dissipation – It has improved the ability to transfer heat throughout the board, preventing uneven heating and damage to the board.
- International Standards – Its materials conform to the established guidelines.
- Conductor – It has exceptional electrical and heat conductor properties.
Kindly message us through our socials if you have further clarifications concerning these features. We will address it as soon as we can.
Materials Deployed in a 3 oz Copper PCB
A 3 oz Copper PCB isn’t an exception; almost all types of Copper PCBs are constructed using Copper Lamination Board. Additionally, it uses the following materials:
- Tin Alloy – It adds up to the overall thickness of the board.
- Conductive Components – It helps to strengthen the circuit integrity of the board.
- Steel Wood – It aids in durability, sturdiness, and reliability.
- Prepreg Materials – We deploy it to withstand extreme temperature conditions.
- Carbon Steel – This adds to the board’s durability since it is shock-resistant.
Please contact us if you want further details regarding its materials.
Choosing High-Quality 3 oz Copper PCB
Since we value our consumers in PCBTok, we want to share with you the factors to consider in selecting a high-grade 3 oz Copper PCB. Here is some of it:
- Weight – It should be on average weight to avoid breakage during use.
- Space – It should have enough space to integrate circuits.
- Availability of Components and Connections – Before you decide to manufacture it, your desired materials should be accessible to the supplier.
- Impedance – The thickness of the PCB is directly proportional to its impedance control; the dielectric material of a 3 oz Copper PCB is capable of dealing with it.
- Flexibility – We suggest picking thick layers to prevent breakage.
Choose the First-Rate 3 oz Copper PCB from PCBTok
One factor to consider in choosing the proper manufacturer for your 3 oz Copper PCB is their experience; they should have adequate knowledge in the industry. PCBTok has more than twelve (12) years of working in the industry.
Concerning this, we can follow your desired specifications without hesitations and problems; we will make it happen regardless of its complexity.
Additionally, we constantly ensure that all of our products satisfy international guidelines and are thoroughly tested to evaluate their performance.
PCBTok utilizes sophisticated technologies and materials in manufacturing your 3 oz Copper PCB. Furthermore, we can provide you with the best deal if you plan to purchase from us. Grab our best deals today, and contact us!
3 oz Copper PCB Fabrication
One of the essential factors to perform is the design of your board since this can dictate the overall performance of it your applications.
In designing your 3 oz Copper PCB, we only consider four (4) essential factors; trace width, trace spacing, hole placement, and connection points.
We carefully consider its trace width since it provides the overall connection of components to the board. In terms of spacing, we ensure that it has ten mils.
Now, for hole placement, we thoroughly consider it since it will determine the positioning of the components and connection points for the location of the electronic component.
If you want more information about this, feel free to contact us.
PCBTok values the quality of its 3 oz Copper PCB for our consumer’s benefit; hence, we always ensure that we adhere to the quality standards.
We complied with the following standards; namely, BS-123200, IEC-61189-11, BS-6221-5, BS-CECC-23200-801, and BS-EN-61188-5-3.
All of these are crucial in determining the performance of your 3 oz Copper PCB. Hence, we are highly strict in complying with these mentioned quality standards.
In addition, we conduct thorough inspections and evaluations to solidify our products’ performance further. We want you to experience only the best items with us.

“This is the first time I’ve had exceptional products and outstanding service. To test its performance, I ordered roughly 20 pieces of 3 oz Copper PCBs, and I’m satisfied with the outcome. Now that all my test pieces are functioning well and my supervisor is impressed with their performance, I’ve decided to repurchase from PCBTok. Many thanks for your tireless efforts, PCBTok!”Alexander Burns, Project Engineer from Raleigh, North Carolina
“PCBTok never failed to impress me every time I order from them regarding their offerings. Since I became their valued customer in 2018, they have continued to treat me with the same respect as before. With PCBTok, I can comfortably say that PCBTok will take care of my concerns because they consistently update me on the status of my PCB orders every week and always show me the full transparency of the steps my items took to get to me. My clients in the industry have expressed satisfaction with the flawless operation of every product I’ve provided for their devices. Therefore, I can say that I am forever grateful to PCBTok. Also, I will continue buying PCBs and availing services from them.”Thomas Barett, Electronics Engineer from Manchester, United Kingdom
“One of the right decisions I made in my life is getting PCBTok as my number one supplier of PCBs. They have the most organized process and professional staff I have encountered. Also, all of the products I always get from them are zero defects, and they always put my concepts in mind and suggestions into action. I feel like I am one of their VIP customers every time I transact with them; however, they do not have that special kind of treatment. They value all of their customers fairly; all the customers, even if it’s your first time purchasing from them, you get to experience the most special treatment. I also love that they provide me with weekly updates concerning my orders; it puts my mind at ease. If you’re still reluctant to purchase from them, you should hurry and grab your PCB products. I guarantee you that you won’t regret it.”Shirley Price, Design Engineer from Juneau, Alaska
