A CAM hold is a delay in engineering caused by issues in the PCB files submitted for the job. The most common reason for CAM hold is DRC errors in the PCB file. DRC stands for Design Rule Check. A PCB must pass a set of rules in order for it to be manufacturable, such as copper-to-copper spacing, and minimum via hole diameter. The manufacturer provides these design rules to the designer, and the designer uses his/her PCB software to run a DRC on the PCB layout. Any violation of the design rules constitutes a DRC error.
You can help to ensure that your PCBs gets manufactured without being put on hold. Please review these common reason for on-holds.
This board hasn’t bigger non-plated holes. So it can’t support the board during Fabrication and Test processes at Hemeixinpcb PCB Production.
The specified stackup total thickness does not match finished pcb board thickness.
Pad to pad distance of less than 7 mils is not enough to build solder mask dams in between pads and at the same time ensure there will be no solder mask on pads.
Due to the ceramic nature type of Rogers material’s, Hemeixinpcb can not run solder mask up to the edges of any routed or scored edge’s with-out chipping the mask during it’s fabrication process. Relieve solder mask 8 mils away from routed or scored edge’s to prevent solder mask chipping.
No specified plating gold thickness for hard gold contacts.

Component of xxx is not widely available，It is difficult to purchase. Please provide your alternative part number of components or provide these component from your side.
The pcb Assembly Drawing does not specify the Reference Designator Polarity (cathode, anode, pin number and what the dot or plus sign indicate) of XXX.
