Price Compare: metal core PCB v’s fr4

Fr4 PCB is a very conventional PCB type of electronic industry.
In LED industry Fr4 PCB not use first widely, its metal core PCB uses more widely.
That is the reason why many people don’t know metal core PCB but call it as LED PCB.
Due to thermal management, metal core PCB has to consider more heat than conventional PCB design process.
Add the metal material also not so cheap.
Resulting in most metal core PCB board is more expensive than the FR4 PCB board.

Heat Performance compares: metal core PCB v’s fr4

In traditional electronic PCB design theory, electronic transfer is the first, then the layout.
Metal core PCB design is more than above two points, add consider a PCB heat transfer.
You know in LED lighting applications, heat increase is the biggest problems.
If you choose high performance metal, this situation may change.
By the way, most metal core PCB heat performance is better than FR4 PCB.

The stack up of metal core PCB board VS.Fr4

We have compared the price and performance, this part we will discuss about construct or stack up of metal core PCB.
Metal core PCB have three layer stack up.
And FR4 stacks up depend on each application, it can have 1, 2, 3 or even more later.
In three layer stack up of metal core PCB, the dielectric layer is most different from fr4 PCB.
Metal core PCB has high heat management most reason is it have dielectric layer.

Application compares: metal core PCB VS FR4

Fr4 PCB application has widely than metal core PCB.
But in LED industry, most engineers will choose metal core PCB for new projects.
For example, a single layer metal core PCB stack up, base is metal core, top is the copper, dielectric layer is in the middle. MCPCB is used instead of traditional FR4 or CEM3 PCB because of the ability to efficiently dissipate heat away from the components. This is achieved by using a Thermally Conductive dielectric Layer.

In this paper, we want to discuss why we should make a panel for PCB design.
If you have visited a PCB fabrication company, you will find most of PCB design as a panel to manufacturing.
4MCPCB experts will main contain Top five situations need to make a panel for PCB.
If you have any thought or ideas, please contact us.

Meet rigid flex PCB mechanical structure requirement

During the PCB manufacturing steps, there were many requirements for mechanical.
Special in CNC drill or rounting process, require the PCB material have good mechanical.
Or can not get right precision rigid flex PCB board.
Even in some simple PCB boards, like metal core PCB, also require making a panel for mechanical consideration.

Consider the solder pad of the component to close the PCB edge

The solder pad of the component is a very important point to rigid flex PCB assembly process.
Not only the quality of the solder pad, but also the distance between the solder pad and the PCB edge can affect assembly quality.
Here Two suggestions from our decades PCB experts below:
If the distance between solder pad with the PCB edge is less than 4.06MM in top layer rigid flex PCB board.
Then the bottom layer, this distance can be reached 5.08 MM.

Consider the distance between the solder point with the edge of the plate

Similar to above, the top layer is less than 4.06MM, and the bottom layer is less than 5.08 MM.
If you have asked some rigid flex PCB designers, most of them were followed those PCB experience.
Also have some special situation, will design a panel for PCB.

Consider the shape during the assembly line

If you have visited the rigid flex PCB plant, you will find some of the PCB have irregular shape or size.
This mean can not successfully through the assembly line.
So make the panel can easy to through the rigid flex PCB assembly line.
That’s the reason why most of the rigid flex PCB will be design panel.

Consider the efficiency of rigid flex PCB manufacturing

In mass production PCB manufacturing, the efficiency is very important.
Make a panel for PCB can be most cost down improve the efficiency.
Special big PCB manufacturing companies, will be more consider panel design to cost down.

We have introduced the PCB assembly quote software.
If you want to choose a good PCB assembly quote UK service, it’s may something different.
So this post will discuss the difference of the PCB assembly quote UK service.
If you have any other opinions, please get in touch with us.

The biggest difference is the professional of PCB assembly quote UK service.

First of all Angel wants to claim that the professional is comparable with other developing countries.
Most of Europe country has the same characteristics with UK’s.
And the professional to know every detail about PCB assembly quote UK service.

The secondly is the delivery time must on time.

Of course, most of PCB assembly quote service must on time.
But during the PCB manufacturing, there were may many problems that can’t image when begin the PCB project.
And those ‘accident’ may delay the PCB quote.
If you have contact with a UK PCB purchase, you must notice this factor.

Through-hole construction PCB Assembling method

Two methods of aluminum core PCB Assembling

If you have visited an aluminium core PCB assembling factory, you may know the line of assembly very long.
It’s not one or two finish, specially assembly mass production aluminium core PCB.
Follow our experience of aluminum core PCB Assembling.
This can be done by through-hole construction or surface-mount construction.

Aluminum core PCB assembling includes the assembling of the electronic components on the respective holes in the PCB.

Through-hole construction PCB Assembling method

In through-hole construction method, the component leads are inserted into the holes drilled in the PCB.
This method is very normal in PCB board assembly, but in the aluminium core PCB industry, was not used very widely.

Surface-mount construction PCB Assembling method

In surface-mount construction method, a pad having the legs similar to the PCB design is inserted and the IC’s are placed or fixed on top of them.
If you have fixed your LED light or aluminium lighting, you will find most light use this method assembly aluminium core PCB component.

The common aspect in both the methods is that the component leads are electrically and mechanically fixed to the board with a molten metal solder.

Previous post we have discussed rigid flex PCB cost comparison, and this post will focus on design comparison of rigid flex PCB cost.

Rigid flex PCB design Cost higher than FR-4 PCB

If you have a new rigid flex PCB design project, you may think the cost is higher than your FR-4 PCB board.
Because there were some cost increase rigid PCBdesign process.
You know rigid flex PCB manufacture has the most complex process, so during its design process should consider more factors.

Rigid flex PCB design mind is differ

We have mention that rigid flex PCB design should consider more factors.
In most rigid flex PCB designers, their desing minds were difference from traditional FR-4 PCB’s.
Design multiple FR-4 PCB into one design to some project, if you use rigid flex board, just only one design is needed with a rigid flex PCB.

Because most of FR-4 PCB board need multiple cables to connect, but rigid flex PCB do not need them.

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.
