    PCB Engineering Questions
    The parameters in gerber files are different from the order details online.
    V-cut standard-Limited to Quick-turn PCB
    Soldermask bridge
    Some drills overlap the slots at GM or GKO
    The outline of shape is too thick to ensure the dimension of PCB
    The layout of PCB is unclear
    Solder mask layer is opening entirely
    Gerber files are not completed
    Route Process in panel file
    Several gerber files have in your order
    Solder mask file is empty or None
    Stackup information
    The tab route is smaller than 1.6mm
    V-scoring line/Slot in silkscreen layer
    Some Issues concerning BGA(Ball Grid Array)
    Design has no silkscreen layer but online is yes with silkscreen
    Please clarify 1-layer or 2-layer
    Requirement about castellated holes
    The distance between the trace and board outline is less than 0.25mm
    The holes is in the trace and it will cause open circuit
    The are some pads out of the board outline
    Two silkscreen files in your gerber file
    Line/Shapes in GM layer
    UL Marking
    Legends on Copper layer
    No Gold fingers design in file
    Drills hurt the circuit
    No Drills in your file
    Legend on every layer
    Soldermask opening for Gold fingers
    Remark for drills is not fitted with the actual drill table in file
    BGA pad opening
    Board outline design standard
    The holes design standard
    There is only top solder mask layer in your file
    Without D-code
    Spiral coil board
    the spacing requirement from slot to copper trace
    Edge plating
    the spacing requirement from hole to the edge of board
    The spacing from one hole to another is too narrow
    It is wrong that copper traces are solder mask opening
    pls confirm whether solid rectangle area should be made as slot or not
    The requirement of beveling on gold finger area
    all the holes are with the same size
    stamp holes standard
    the hole limitation for single-side Aluminum boards
    the spacing from hole to trace
    limited holes spacing
    the bottom silkscreen is mirrored
    Do you need round holes or slots holes made?
    Mask openings are smaller than copper pads
    notes in the order are different from the designs in the files
    do not design texts on the copper layer
    drills are not matched with pads
    Negative or positive inner layer
    Silkscreen standard size
    silkscreen size and spacing in solder mask layer
    Remark on rectangle slot
    How to regard GPT or GTP
    Negative legends in copper layer
    Slot in oval pads
    Which layer to put round or any shape of cutout
    There do not have fiducial marks or tooling holes on break away rails
    There is no stamp holes on tab routing
    The non plated holes break traces
    No layer orders for multi layers boards
    There is no solder mask openings on some pads
    The layer order information you filled online doesn’t match the name suffix in gerber file
    There are no drills in the areas pointed with arrows
    Solder mask opening of some pads is too much which cause copper open as well
    PCB file you uploaded seems the production file, not the original PCB file
    Negative legend dimension is too small for production
    How to design cutout or big hole
    NPTH design rule
    Slots standard size - Limited to Quick-turn PCB
    Confirm the panel way of the boards
    Vias process of design is different from order details option
    The castellated holes are partial set in outline instead of in the center for common designs
    min non-plated holes
    silkscreen over pads
    Spacing between silkscreen and openings
    Copper line and the pad are not connected
    Break lines exist in your file
