We used a microscope to inspect the die surface of MPXM2053GS, which is covered by gel. We found there were holes and cracks on the gel. The electrical tests were passed. Does anyone know that if this is normal or will affect the long term performance?
Hello,
Welcome to the DigiKey TechForum. We don’t have any information on the longevity of the parts based on what you found with the microscope. The good news is they passed your testing but for more in depth information you may want to contact the manufacturer direct to see what insight they can provide.
