All new products take a period of time to stabilize and ramp the yield. Devices which use fuse trimming can at times take longer to ramp due to the added complexity of the trimming. yieldHUB software can help you to ramp the yield faster. The key is to be able to analyze in the right way, all of the data you have as soon as it is available.
To help our customers with this we have an application note to help our customers understand how to analyze the trimming data and improve the test programs. To have the applications note emailed to you please see below to contact sales.
