The features of PCB for automotive industry

Increase the market share of PCB for automotive

Battery Electric Vehicle becomes more and more and resulting in increase requirements of vehicle PCB board. And the requirements were a range of from prototypes to production and from simple to the most advanced technologies.

The features of PCB for automotive industry

Difference from rigid PCB use in automobiles, the PCB type use in automotive have increased. The most automotive electronic designer will consider rigid, flexible, and rigid-flex printed circuit boards. The main reason was harsh condition require high performance PCB for automotive and meet demanding electronic applications that can withstand high heat, speed and motion. Not only the performance, but also require reliability increase.

Need more flexible PCB for the automotive industry

Now automotive has increased very fast, not only increase the count of automobiles, but also the new technologies. And more and more new technological requirement new innovations and high performance PCB board. The automotive industry is constantly developing automobiles in order to strive for enhanced safety and superior technological abilities. These constant innovations increase the need for rigid and flexible circuit boards to heighten the overall automobile experience for a customer. That was the main reason more and more MCPCB manufacturers turn to produce flexible automotive PCB.

The most common Hybrid Metal Core PCB types

Hybrid Metal Core PCB manufacture process

First of all, David have to introduce a new PCB definition: Insulated metal substrate (IMS).
Its construction has a sub-assembly of non-thermal material, and usually this Hybrid Metal Core PCB manufacture processis independent.
In a ‘Hybrid’ IMS construction a “Sub-assembly” of a non-thermal material is processed independently.

New Hybird Metal Core PCB manufacture process is different

Some creative MCPCB manufacturers make a Hybrid IMS PCB bonded to the aluminum base with thermal materials.
That’s the reason why so many hybrid Metal Core PCB boards have difference when compares with before manufacture process.

Why we add aluminum base in metal core PCB manufacture process?

If you have read our aluminium PCB board article, you will find the aluminium layer can decrease the temperature of products.
Bonding this layer to an aluminum base with thermal dielectrics can help dissipate heat, improve the rigidity and act as a shield.
Due the metal core PCB manufacture process, some fabrications may use metal alloy instant of aluminium base.
By the way, even the metal alloy core PCB cheaper than metal core PCB, but the latter was recommended due to the reliability.

The most common Hybrid Metal Core PCB types

Now, more engineer prefers to choose hybrid metal core PCB, but most of them don’t know the full name of this board.
David just wants more guys know the truth of MCPCB, and introduce the most common hybrid aluminum PCB.
The most common construction is a 2-Layer or 4-Layer Sub-assembly made from conventional FR-4.

LED light circuit board is different from the normal PCB board

LED lights circuit board difference with normal PCB

This post will discuss two different type PCB board.
If you have any about the circuit board LED lights question, please let me know.
We will update your opinion on this post.

What is the normal PCB board?

Here Allen don’t want to use the wiki definition of the normal PCB board, if you want to see it, please search on google.
When you unscrew the circuit board and take it out, you can see that the circuit board is a thin piece of fiberglass that has thin copper “wires” etched onto its surface.

LED light circuit board is different from the normal PCB board

The first is about construction layer.
LED light circuit board has three layers, top is the circuit layer, dielectric layer and the thermal conduction layer.
But most of the normal PCB board, top layer and inner layer were both circuit layer.

The second difference is application.
You know most of MCPCB board use LED lighting industry.
But the normal PCB board can use all electronic industries.

The theory of how to repair multilayer PCB boards

The ignore assembly cost of the rigid flex PCB board

We have discussed the right way calculated rigid flex PCB assembly, this post is related to this topic.

Rigid flex PCB and rigid PCB assembly method comparison

In rigid flex PCB assembly solution just require one assembly step.
But if use cables assembly on rigid PCB board, there were two or more steps to be assembly.

The ignore cost during rigid flex PCB assembly

If you just consider the price from rigid PCB supplier, you may speed more money to assemble you rigid PCB project.
What is the extra ignore cost during rigid flex PCB order?
Emma has asked this question to experience PCB experts, and get the answer below.
The ignore cost during rigid flex PCB assembly must include items such as: the cost of kitting for assembly, labor, in-process inspection, cable assembly, test, final test, PCB tooling and test, and the costs associated with the engineering time required for each of these operations.

The risk of high temperature circuit board application

Top three features of high heat circuit board

This paper is going to discuss the high heat circuit board.
As we know the high heat circuit board is a high end PCB board type.
The designers have squeezed ever more performance out of printed circuit board.
This means that high heat circuit board designers should consider high temperature applications in the first.
If you have know electronic theory, you may find this is difficult to finish.
So we will from some different factors to discuss the feature of the high heat circuit board.

The risk of high temperature circuit board application

As we know power densities can affect the product temperature.
Then the power densities are on the rise, the temperature also rises.
HTD PCB manufacture experts told us that the risk of high temperature can wreak component.
Not only the havoc on the conductors, dielectrics, but also the circuit board itself.
As consequence of high temperature, you should consider more during the design process.

The electronic performance of high heat PCB board

We have known the high temperature can affect components.
This means the temperature also affects thermal and electrical impedances.
During the elevated temperatures, those electronic impedances have bad performance.
Causing erratic system performance, until it outright fails.

High heat PCB have differences in thermal expansion rates

If you have learned some PCB manufacture process, you may know the thermal expansion is an important factor.
As well know it's a measure of the tendency of a material to expand when heated and shrink when cooled. 
Its can be cause cracking and connection failures during PCB assembly process.
Between conductor and dielectrics generate mechanical stress.
By the the highest temperature PCB boards are subject to cyclic heating and cooling.

The Reason Why HTD Shared Top 100 PCB manufacturers?

-Many  oversea PCB electronic company don’t know the China PCB industry.
-Some of China PCB manufacturers produce bad quality
-Better service from Top PCB manufacturers

Top 100 PCB manufacturers Report

Recent, there was a ranking about Top 100 China PCB manufacturers on wechat.
Jim want shared this report to all PCB purchase managers.

HTD Group Circuit Board Solution

Now HTD capabilities is ranking the 51th on the top PCB manufacturers report.
So HTD have more oversea customer.

The time of PCB manufacturer customers' reference

If you have experience in new products development, you may know the risk of a PCB manufacturing sourcing is really hard work.
This post we will discuss this topic.

To measure a good PCB manufacturer

You know, to measure a good PCB manufacturer have many factors.
But the customer references are the first factor.
Because you can from those cooperated customer to analysis.
What is the most hot sell PCB type and the PCB market share.

The time of PCB manufacturer customers' reference

This issue may most PCB purchase want to know.
Under HTD circuits experience, this is often done by a supplier before extending credit.
The same process can serve the end customers well.
