How To Detect Counterfeit FPGA Circuits
While receiving a counterfeit part is never fun, it’s even more frustrating when the component is something vital to your project such as a FPGA (field programmable gate array). Although there is a lot of government increased security measures to try and minimize the amount of counterfeit electronics, it still does happen and always will in the foreseeable future.
So, how can spot a counterfeit FPGA circuit?
The first way is to look at the sizing of the new electronics. If you are getting the same electronics, measure it against each other. Unless the FPGA you have ordered has been significantly updated since your last purchase, they should be the same size.
Another way you can check for sizing is to measure it. Jump online and find out what the exact measurements should be. Once you know, take out a measuring tape and compare with the piece of electronics you received. If the dimensions are different, it may be counterfeit.
Look For Logos
Most companies want their electronics to be branded. This means they have their logo somewhere on the product. Prior to purchasing a new component, go online and find out if it is branded in a specific spot. Perhaps that brand always marks theirs in the same place each time. This is an easy way to look if it is the exact logo in the correct spot quickly.
Take An Inside Look
If you are investing in a piece of electronics, it may be worth it to do an x-ray inspection. In order to do this, you will be able to see any wire bonds and even find out if it has delamination. By giving the potential electronic purchase an x-ray, you will be able to quickly tell if it is authentic or not.
Test It If You Can
If you have instruments, you can do a quick electronic test to find out if it is counterfeit. This will be harder to perform if you don’t have any electrical testing equipment, but if you are making a large purchase or a purchase of a lot of the same product, it may be worth renting one.
Check The Color
When you look at the piece of electronics and it is not quite the correct colour, this is another quick way to determine if it is counterfeit or not. Most electronic components are produced in large batches and the colour is typically is uniform. If you suddenly see it is grey instead of black, this can be a sign it’s counterfeit.
Find A Company You Can Trust
The final –and possibly most effective—way you can ensure the FPGA you receive is legitimate is to work with a trustworthy company. For example, There are some offers of Direct Components Inc. FPGA by Altera that are 100-percent guaranteed to be genuine. Make sure to check reviews online for the company you are considering. Although this may not give you your answer, if they do have bad reviews or someone has experienced being sold counterfeit products from them before, you may want to look elsewhere.
As you can see, there are many ways to ensure you are not being sold a counterfeit product. Unfortunately, you can’t always be sure. The point of a counterfeit product is to look as similar as possible to the untrained eye. Do your research prior to purchasing the electronics so you don’t have any regrets.
