How Can You Verify The Performance Of Rogers 4350b?
You can verify the performance of Rogers 4350b by running different tests. Now, We are going to explain some tests for your convenience.
Flying Probe Test
This is a custom fixtureless test. You need to move the probe used in the test to different points of a RO4340b PCB. That’s why it is called the “Flying probe test”. Here, you must follow the guideline of a definite software program.
You can identify the defects of resistance, capacitance, inductance, diode, shorts, opens, etc through this test. This is a cost-effective non-powered test. It requires additional time compared to the other tests.
ICT requires a huge number of drivers, sensors, a specific fixture, and software. Here, a bed of nails acts to connect the probes and access points of the PCB according to the fixture. Particular pressure is required to keep the joint intact.
The driver tester verifies the solder connection. The software provides the instructions for the test. It is also called the “Bed of nails test”.ICT test is a little bit costly but effective. You can minimize the cost by testing bulk amounts of Rogers 4350b PCBs.
Again, the value of different components, shorts, opens, IC operations can also be checked by conducting the in-circuit test.
This test checks whether your Rogers 4350b PCB meets all required standards. The functional test takes more time. But, it is effective to ensure the performance of RO4350b.
Automated Optical Inspection Test

That’s why you can rely on Rogers 4350b PCB without any hesitation.
How Can You Manufacture a Rogers 4350b PCB?
Since Rogers 4350b PCBs are widely used in the electronic world, it is very important to know its manufacturing process. There are numerous ways of manufacturing Rogers 4350b PCB. We are explaining the gist of basic manufacturing.
First, choose the plain Roger PCB board. Next, cut down the unnecessary copper. Then, you need to achieve the proper track pattern. Normally, a photo-resist covers the Cu of the PCB. Then, you have to put light on it via a photo mask.
Rogers 4350b PCB Manufacturing
Thus, images of the tracks can be passed to the photo-resist. Now, place the photo-resist in a developer. It helps to mask the required region of the PCB. Next is the time of chemical etching.
Here, you have to put PCB in the standard solution of Ferric Chloride. It acts to etch the region where no copper is mandatory. PCB should not be kept in the solution long. Then, Ferric Chloride will hamper the photo-resist.
These are the basic steps of Rogers 4350b PCB manufacturing.
The photographic method is highly used for this manufacture. But, there are some other ways available. Such as: Using a milling machine to eliminate copper from unwanted portions.
This automated method is not good for the massive manufacturing of Roger 4350b
PCB. Again, the silkscreening process is also used to manufacture RO4350b PCB.
Here is a video for you to learn the details of PCB manufacturing:
How To Choose The Best Rogers PCB Laminate?
