Light weight aluminum PCB vs. Copper PCB, benefits and drawbacks

Cost Comparison

The PCB is the most expensive metal core printed circuit board. The thermal conductivity is much better compared to PCB, this is usually used in high regularity circuit style.

Thermally Conductivity Comparison

The thermal conductivity of copper PCB is more than that of aluminum PCB. The higher the thermally conductivity is, the greater the transfer efficiency and the better the thermal diffusivity. Copper PCB requires a thick copper aluminum foil for its large existing lugging capacity.

Innovation Practices

The thickness is 35μm ~ 280μm. A heavy copper PCB is produced in the same way by engraving thick copper outfitted laminated board material. It utilizes layering modern technology as well as a combination of plating as well as etching to create the heavy copper trace elements and ignorable damaging. Copper PCB can be sophisticated and therefore processed in a convex platform. The elements can be obtained as a result of the excellent grounding as well as warmth dissipation.

What is CPS LED

CSP LED is a chip made by chip-scale package (CSP), which is a type of integrated circuit package. The dimension of CSP led is 2mm * 1.6mm. LUMILEDS LUXEON ZES and SEOUL Semiconductor Z8Y11 are one of the most popular CSP chips on application.

CSP is based on chips chips technology, CSP is make CSPs are typically constructed using a lead frame, in which lots of gadgets could have been on the same substratum, permitting the setting up of numerous packages wholesale. Doing so makes the most of the use of interposer location. The on the interposer using epoxy, normally of non-conductive child (although conductive epoxy is also used when the backside needs to be connected to the circuit). The gold or light weight aluminum cords. Due to the fact that the procedure circulation of CSP light grains is intricate as well as delicate, its manufacturing cost as well as application cost are relatively high.

CSP could be developed on the headlight light bulb to mimic the halogen filaments properly. And so A collection of CSP LED headlights could offer over 4000 lumens of outcome.

Solitary Layer PCB vs. Double Layer PCB in Automotive LED Front Lights Bulbs

In typically, FR4, aluminum PCB and copper PCB can be made into a single layer of PCB or double layer PCB

Single Layer PCB

Solitary layer PCB is one of the most widely used, due to the fact that it is easy to design and method. This PCB is covered on the one side of the board. Solitary layer PCB with an excellent warm dissipation, each chip dissipates warmth on one PCB, the LED headlight can be in a high lumen. Yet the size of 2 chip of 2 solitary layer PCB is too broad that 3mm. Limited by the size, it could not simulate the tungsten cord, the beam is unclear with a dark location.

Double Layer PCB.

This PCB covers 2 conducting material on the both side of the board. It provides a more detailed distance between the two sides of the chips, which is similar to the density of halogen tungsten cord. For this outcome, it is the light bulb, the beam is more better. However, the two sides of chips dissipate heat on one PCB, which could not be too high, so it restricts the lumens for LED front lights.

It is not based on the area of PCB regarding the PCB warmth dissipation issue. Thermal Management innovation is an additional core component of PCB application. In the next post, I want to talk about thermal management Printed Circuit Board (PCB) innovation, especially SINKPAD Technology, is the effective solution for car led lighting.
