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.

Rigid flex PCB design Cost higher than FR-4 PCB

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.
