Overview
Heavy copper PCBs are widely used in power electronic equipment and power systems. The growth trend of the circuit board industry, the quality of the finished copper of this unique type of a heavy copper circuit board is greater than4 ounces (140 microns) compared to 1 ounce (35 microns) or 2 ounces (0 microns) of copper commonly found in standard printed circuit board copper thick copper. The extra weight of the copper circuit board enables the circuit board to handle higher currents, provide good heat distribution, and install complex switches in the smallest space. Other advantages include increased mechanical strength of the joints and the ability to integrate multiple weights to make smaller products. Circuits of the same level, and can use unique materials at full load with minimal risk of circuit failure. Alternatively, you can choose Quartz Crystals, the best equipment for a PCB Manufacturer.

High-quality copper PCBs
PCBC art has ten years of experience in manufacturing and assembling high-performance and standard high-performance equipment. Copper PCB helps our customers achieve their performance and profitability goals. We use this as our standard practice for highly skilled engineers. We can design and manufacture each schematic file and solve any problems and problems before production. This will help to ensure that the finished electronic board meets your expectations. Our well-trained employees include internal quality control, and we guarantee the quality of circuit boards. To correctly manufacture heavy copper PCBs, you must use larger track width and track spacing due to the increase in the weight of the corresponding copper wire.

Heavy copper chain structure
Standard printed circuit boards, double-sided or multilayer, made by a combination of copper plating and etching processes. The circuit layer is made of thin copper foil (usually 0.5 oz / ft2 to 2 oz / ft2). Etching to remove unwanted copper and electroplating increases the copper thickness on the silver surface, traces, pads, and vias. All circuit layers are laminated with an epoxy resin carrier (such as FR4 or polyimide) into a complete package. Heavy copper PCBs manufacturers produce it similarly, but components were formed entirely by etching thick copper-clad laminates in the past heavy copper, resulting in uneven sidewall markings and unacceptable cutting. Advances in electroplating technology make it possible to use the characteristics of heavy copper. The combination of plating and etching results in straight sidewalls and smaller undercuts.
Heavy Copper PCBs Capabilities
When considering the use of heavier copper structures, consider the following options. We provide information about the production of heavy copper PCBs. On which final product will this part be installed? Will it be exposed to the natural environment, extreme heat, extreme cold, or water? Prototyping is common for heavy copper products to obtain UL approval and meet deadlines. Knowing more helps us succeed. Will this project be permanent in the next few years? For small batch and large batch production, do we have multiple production options, or do we buy one at a time? Explore memory plans, UAE cost savings, and Kanban. Epic provides all possibilities.

Advantages of Heavy Copper PCBs
Heavy base copper PCBs offer numerous advantages such as:
- Reduced wired buss forms lead to small PCB size
- Easy integration with high-power lines and control circuits
- Enhanced thermal stability reduction with the increase of copper plating in the heat vias
- Increased current carrying capacity, as well as resistance to thermal strains
- Reduced layer count due to accessible business of multiple copper weights on a single layer
- Enhanced manufacturing power in PTH Holes and connector sites
- Allow use of imported materials to their full potential without making circuit failure
- Heavy copper-covered vias carry high current through the circuit board and help transfer heat to the heatsink on the outside
- The PCBs can oppose high thermal cycling
