Impinj is changing the Monza X-8K package symbolization to a single-line marking. This modification enables AOI (Automated Optical Inspection) equipment to more reliably identify the Pin 1 indicator for orientation and alignment purposes. Many AOI tools search for alignment indicators simultaneously at all four corners of the package. This change eliminates the presence of alpha/numeric characters close to the Pin 1 indicator which could inadvertently come into the AOI field of view, thus causing confusion with the actual Pin 1 indicator.
The new marking specification is as follows:
| MARKING SIZES AND TOLERANCES (in µm): | |||
|---|---|---|---|
| Description | Size and Tolerances (µm) | ||
| Min | Nom | Max | |
| Pin 1 diameter | 250 | 300 | 350 |
| Pin 1 X placement | 110 | 210 | 310 |
| Pin 1 Y placement | 180 | 280 | 380 |
| Character height | 350 | 400 | 450 |
| Character width | 150 | 200 | 250 |
Marking legend:
 |
Pin 1 indicator |
| 1 | Production year: Single digit marking (e.g. 9 for Year 2019) |
| 2-3 | Production work week (e.g. 52 for WW52) |
| 4-5 | Fixed marking: "X8" |
To differentiate parts with the new single-line marking from the previous version, Impinj is assigning a new ordering part number. The part number will change from IPJ-P6005-X2AT to IPJ-P6005-X2BT. Customers will continue to receive units with the current marking (IPJ-P6005-X2AT) until existing inventory is depleted. Based on the current consumption rate, the estimated transition date to the new part number will be March 2020.
