PCB design in the automotive electronics, often carrying power device substrate and
circuit substrate using separate settings. Substrate carrying high power devices is the
use of Ceramic PCB. More in Ceramic PCB circuit wiring for control circuit, in the
production process is more difficult to achieve. Will carry the ceramic substrate of
power devices are replaced by organic resin substrate thick copper PCB, achieve the load
current circuit and control circuit integration.

Thick copper base plate and wire harness to achieve the integration of more and more
applications in the automotive field. This transforming many high current wiring harness
to circuit wiring, control circuit and power circuit in one method in the PCB, reduces
automotive electronic components connected, assembled the cumbersome, improves
reliability, easy to realize miniaturization. ECU also using heavy copper is based on
heavy copper of high reliability, high thermal resistance, high current through the
nature.

Heavy Copper PCB’s Advantages

Heavy Copper PCB Manufacturer, Heavy Copper PCB Factory, Heavy Copper PCB China Manufacturer, Heavy Copper PCB China Factory

A growing number of power electronics products are taking advantage of an increasing trend in the printed circuit board industry such as heavy copper PCB. Most commercial PCB are manufactured for low-voltage or low power applications with copper traces.

The advantages of heavy copper printed circuit board:

1.Increased endurance to thermal strains.
2.Increased current carrying capacity.
3.Increased mechanical strength at connector sites and in PTH holes.
4.Use of exotic materials to their full potential without circuit failure.
5.Reduced product size by incorporating multiple copper weights on the same layer of circuitry.
6.Heavy copper plated vias carry higher current through the board and help to transfer heat to an external heatsink.
7.On-board heatsinks directly plated onto the board surface using up to copper planes.
8.On-board high-power-density planar transformers.

Heavy Copper PCB’s Using

Vast majority of Heavy Copper PCB for large current substrates, large current substrates the main field of application is in two

fields: power supply module (power module) and automotive electronic components. Its main electronic products, some
identical to conventional PCB, such as portable electronic products, network products, base station equipment. Also different
from the General area of PCB, such as automotive, industrial control, power supply module.

Large current substrates and conventional printed circuit board on the effects vary. General PCB’s initial main function, is used
to form the signal wire (wire). With the development toward the direction of HDI PCB technology, this signal transmission wire
line width is becoming increasingly thin, wire Heavyness (Heavyness of conductive PCB) is becoming increasingly thin, copper
foil Heavyness 35um, thinner 18um 12um 9um and even thinner. Large current through the bearing substrate for power
devices, the main effect is to protect current-carrying capacity and the power supply is steady. Development trends of this
large current substrates are carrying larger currents, thermal requirements issued by the larger device, so by increasing the
current, substrate the Heavyness of copper foil is also Heavyer. Manufacturing, for example, large current substrates 210um
Heavy copper foil is also used to be routine. There should be used instead of cars, robots, power, previously used bus
(Busbar), conductor of harnesses base plate Heavyness has reached 400um-2000um.

Since the advent of Heavy copper printed circuit board, PCB applications into a new industrial product areas: power
electronics.

Organic resin of Heavy copper PCB has can achieved base board miniaturization, thin type of, multilayer of of advantage, due
to in recent years electric, mixed power car, robot, by with of power power and current controller (DC-DC conversion device)
power switch, motor circuit, fuse device, are more tends to miniaturization, this for Heavy copper PCB alternative original
General used of Ceramic PCB created has opportunities, speed up has pace.

Heavy copper PCB design, advances in manufacturing technology, promote the power circuit (load current) and integration for
the control circuit.

Heavy Copper PCB’s definition

heavy-copper-pcb-1

 

Usually nominal thickness 105um copper foil for PCB and above (including the surface treated electrolytic copper foil and rolled copper foil) are collectively referred to as thick copper foil. Thick copper foil, in the PCB industry and used with copper foil thickness of copper foil manufacturing industry is divided into three varieties, greater than or equal to 105um-204um Heavy Copper PCB, over 300um called extra Heavy Copper PCB, 600um known as Super MAX Heavy Copper PCB.

Heavy copper conventional electrolytic copper foil (or rolled copper foil) performance, as a large current substrates of conductive layers or inner core heat sink metal layer also has a special performance requirements. These special performance requirements to meet the application conditions of products and raw materials, processing conditions, and so on. On the application performance requirements, most notably in the thick copper circuits on the stability of the large current and better disseminated by the load current generated in the base plate of high thermal properties.

Made of thick copper foil and extra thick copper printed circuit boards may be called a thick copper printed circuit boards. Using conductive material (copper) and substrate materials, production technology, applications and General PCB different, therefore it belongs to a special kind of PCB. Thick copper PCB applications, and demand has been rapidly expanding in recent years, has become a popular varieties of PCB has good market prospects.
