Embedded Busbar PCB

You can rest assured to buy Jiubao Embedded Busbar PCB from our factory. Busbars are high current printed circuit boards and also the integration of busbars and electronic systems, a technology that combines high current and microelectronic control in a single system for powertrain and power applications. This combination is achieved by adding busbars and other bulk copper wires to the printed circuit board (PCB) to achieve high current carrying capability and heat dissipation of power dissipating components.

Introduction of Embedded Busbar PCB:

Embedded busbar PCBs are widely used, meeting the heat dissipation requirements of more and more high-strength components and high-power components, and also meeting the heat dissipation requirements of high thermal conductivity copper. Embedded busbar PCB printed circuit board refers to embed the copper core into the pre-milled slot during pressing. Laminated prepregs are used to connect the copper core to the printed circuit board. The embedded copper core is in direct contact with the inner FR4 epoxy board, and when the PCB is used the heat is rapidly transferred to the copper block. The heat is then removed from the air through the copper core. The heat dissipation effect is better than that of the buried copper core PCB, the process is simple, the cost is low, and the application prospect is wide. Embedding the copper core into the PCB is a key process, which needs to be matched with technical difficulties such as the shape design of the copper core, the size and smoothness of the copper core and the milling groove of the PCB, otherwise reliability problems will easily occur. JBPCB has many years of experience in manufacturing embedded busbar PCBs, providing technical support and supply for many well-known new energy vehicle industries.

With the development of new energy vehicles, there are more and more innovations in new energy vehicle batteries. New energy vehicle battery is a new type of vehicle battery that uses new energy technology to reduce "greenhouse gas" emission pollution. The battery needs to be connected to the charging pile for charging, and the fast-charging copper embedded bus pcb has a large current flow capacity and is a conductor with extremely low resistance. The main function of the busbar is to conduct high current. The busbar pcb requires a high current distribution unit (also known as the busbar copper bar electrical busbar), which is widely used in the new energy industry, including electric vehicle motor controllers, high-voltage power distribution boxes, frequency converters, and photovoltaic inverters. High-voltage, high-current conversion device busbar pcb products for equipment such as inverters, wind power converters, rail transit, motor vehicle traction devices, communication and data equipment. The product realizes simple and traditional high-voltage and high-current distribution, and can be deployed into traditional complex low-voltage control circuits. Typical applications in the automotive industry or avionics are handling currents around 1000 amps.

Used in new energy vehicle distribution boards, circuit boards, battery packs, power supply units, battery pack electric control cabinets, rail transit, photovoltaic inverters, wind energy, communications and data, power electronics, high-voltage distribution boxes, frequency converters, and motor vehicle traction devices , communication and data equipment, high voltage, etc., high current conversion devices, they also provide structural rigidity to the circuit board.

The main purpose of the bus bar is to conduct large currents, exceeding the current traces that a standard circuit board can provide. The product has independent distribution of large current, carrying high voltage, stable large current, strong insulation, high efficiency, long service life, efficient heat dissipation performance, stable and safe.

Q1: Do you have the automobile industry certificate?
A1: Yes, we have IATF 16949 certification for the automotive industry, to help realize printed circuit boards for high power applications, we can also provide UL certification.
Q2: What documents should we provide for copper core embedded in PCB and laminate structure is different?
A2: The designed drawings will be distorted when opened or interpreted by different software. Gerber files are the best (Protel, power pcb, PADs) software drawings and text descriptions.
Q3: How should the laminated structure be expressed?
A3: First, Gerber files have each layer, and each layer in another PDF can be marked with different colors + text description.
Q4: What are the requirements for the storage time and environment of the embedded busbar PCB?
A4: The temperature and humidity of the embedded busbar PCB will affect the life of the product. Under the vacuum plastic film packaging, the temperature is 25±2℃; the humidity is 55±5% RH, and the quality is guaranteed for 6 months. If the vacuum plastic film packaging has been removed, the embedded busbar PCB welding position DNIG will be exposed to the air for a long time, and oxidation will occur, which will affect the welding components.
