Common Misconceptions About Flexible And Rigid PCBs

1. Common Misconceptions About Flexible And Rigid PCBs You should prepare yourself well for some shocking facts that will hit you. These will challenge the concepts that you had regarding printed circuit boards. Of course, there are some things which you know are correct. Then again, people harbor several misconceptions regarding PCB designs. These are concepts that they learned or heard. The problem is that those concepts aren’t applicable anymore. Therefore, it is time for you to change them. If you cling to them, then you may end up creating defective boards. In the end, the device in which you are going to install them will suffer. Sometimes, your misconceptions may even lead you to incur higher costs than usual. 1.They are same: Some people think that both rigid and flex circuits have the same design rules. Well, they are wrong even if their purpose remains the same. The designers of flexible printed circuit cable pay attention to minimize location-based stresses. After all, it is possible to fold and bend them. There are also differences in the dimensional stability of the base materials used. You may have enough knowledge regarding rigid PCBs. If you are new to the world of flex PCBs, then you have much to learn. 2.Circuit board damages: Another misconception is that via in pad will be detrimental to the circuit board. There are a few situations where this notion is accurate, but only if you don’t use it properly. The manufacturers of flexible printed circuit cable say that you must cap your via in pad.

2. Otherwise, plating chemicals may slip inside and stay trapped in there. Then again, it isn’t a reason valid enough to avoid using via in pad entirely. Via in pad has many essential uses. 3.Ninety-degree angular traps: There was a time when ninety-degree acid traps used to be true. When manufacturers used acid to etch on the PCBs, the acid would accumulate in the corners. Eventually, it would lead to problems. That is why manufacturers have been creating forty-five-degree angles in their PCBs. Now, they use alkaloids to do the etching, instead of acid. 4.No eco-friendly: In the world of today, people replace electronic gadgets every other week. You may be wondering what happens to those PCBs of old phones when people shift to a new one. Engineers never sit tight and use what they already have to make new gadgets. Many companies are manufacturing biodegradable PCBs nowadays. They will break down and disintegrate when people discard a machine.

3. 5.Perfect designing: Finally, people believe that a beautifully designed PCB is the best there is. Indeed, engineers are artists in disguise. They prepare elegant and fluid designs. However, what works perfectly in theory, may not do anything in the real world. You have to abide by the laws of physics to make a PCB perform. Then again, you have to tweak a few things so that the PCB works. It doesn’t mean that the component will be aesthetically pleasing. Final words The last misconception is regarding the software used to design the PCB. Of course, computer-aided designing systems make everything easier. You can create a virtual design of the PCB and then work on the real thing. Some engineers blame the software program that you are using to create the designs. However, experts say that it doesn’t matter. Of course, you should use a software program that experts recommend. Conversely, it won’t help you solve any issues that you face during the actual work.
