OCXO Daughter Card V4 - Silkscreen Designator Mismatch for R8 and R33 #107

Open skear opened 6 months ago

skear commented 6 months ago

There appears to be a mismatch between the silkscreen designators and the actual footprints for R8 and R33 on the OCXO Daughter Card V4 PCB.

According to the BOM, R33 is an 0201 component, and R8 is a 0402 component. However, the silkscreen designators on the PCB are swapped.

PCBWay noticed this discrepancy and reached out to confirm the correct placement, which prompted me to open this issue. Correcting this in a future revision might help streamline the manufacturing process.

Below is an image provided by PCBWay highlighting the issue as well as a snapshot from Altium viewer showing the mismatch.

Thanks for highlighting this issue! If I respin the OCXO board, will address this. If you want to request a merge to fix this, we can do that as well no problem.
