How To Test Silicon Nitride Substrate?
It is possible to test Silicon nitride substrates manually and automatically. But automated processes are more effective for delivering the best report. The most reputable inspections of these PCB substrates include-
Automated Optical Inspection (AOI)
This test checks the electrical and mechanical properties of substrates. During the AOI test, a well-made machine takes photographs of Si3N4 substrates from different sides. This machine compares 2D and 3D images with an ideal substrate.
That’s how the AOI test can identify the defects. This test mainly focuses on finding missing components, improper connections, etc. You can get a trustworthy result through the AOI test, but it is costly. So, you can optimize your cost by using this inspection in the Substrate used in the production of power modules.
Automated X-ray Inspection (AXI)
The AXI test is another dependable automated process to identify faults in Si3N4 substrates. It is primarily viable to check dimensional faults like improper substrate size, thicknesses, deficiency in thermal tolerances, etc.
Here, the. X-ray penetrates the substrate and a skilled inspector checks the critical portions of this PCB material. This test is also expensive but effective.
Si3N4 Substrates Inspection
Except for these automated tests, you can depend on manual inspections. Besides, thermal tests, peel tests, etc are useful to check the thermal management of Si3N4 substrates. You can choose a PCB manufacturer that can take care of substrate testing without causing any difficulties.
Which Things Do You Need To Consider While Choosing A Reliable Silicon Nitride Substrate Provider?
Silicon nitride substrate is a crucial element in the production of electronic components. You have to ensure the best result of using this PCB substrate so that it can match your requirement.
In that sense, the necessity of choosing a dependable substrate provider is beyond question. Only an experienced and skilled fabricator can bring out the desired output from this substrate.
But how do you find a reliable Si3N4 substrate provider?
You have to focus on some points that will provide a clear view of the fabricator’s capability. Such as
The fabrication process of any kind of substrate requires immense experience with sound skill. Si3N4 substrate is not a different case. You must choose a fabricator who has enough knowledge of different aspects of machining and layering of this substrate.
Besides, technical staff should be skilled enough to handle minor to major problems of the fabrication process. You can get an idea about the experience of Si3N4 substrate providers from their website and customer review. If you get a positive vibe about a manufacturer from these sources, you can go for that.
Si3N4 substrates need to be gone through several tests so that you know about their functional properties properly. That means test equipment plays a crucial part in this matter.
It is necessary to select a substrate provider that offers sufficient testing facilities with well-planned factory services. If your manufacturer can conduct inspections on their own, it will save the production cost to a certain degree.
But you can rely on OEM and ODM services in the case of not having equipment facilities. In that case, you should be determined about its ability to deliver work within the lead time.
This is another important feature when you are choosing a Silicon Nitride substrate provider in China. You can’t afford a product that is economically not viable. To be sure about this issue, you can check a fabricator’s cost-to-performance ratio. Always try to get the best service within your budget and capability.
