    Panel Design of Circular PCB

    Hello FvM, Thanks for the reply. 2mm is the Slot width. But my question about clearance B/W the PCB in a Panel. Most of supplier guidelines shows, Min. 10mm Clearance B/W PCB is required Especially for Circular PCB. Why for Circular is my question?(to have better mechanical Stability, but...

    Panel Design of Circular PCB

    Hello All, I have circular PCB of 47.6mm X 47.6mm Where i have planned to 2 X 3 matrix panel Design, which has total of 6 Boards in a Panel. Now when I design Panel, I read most of the PCB Suppliers area suggesting to keep 10mm(2mm Slot width) Clearance B/W Each PCB, So 6mm of Base material...

    [SOLVED] Solder mask defined pads

    Hi All, I am using 81 pin WLCSP package IC. In socket recommended pad dia is 0.3mm. But for 0.4mm pitch suggested pads is 0.265mm pad. This is not matter for socket still i have to connect 2,3 pads diagonally in top layer. To do this i have to reduce some pad size. I need to know whether...

    Does Kicad support for Micro blind via

    Hi All, Does Kicad support for Micro blind via? Say i am using micro vias of 10mill pad and hole 4mil. I can route on the 1-2 or 6-5 for 6-layer board. But inner layers it is not supporting(2-3,3-4.4-5). Please suggest some solution.] Regards, Arunmaran

    [Moved] ESD diode check for analog switch, value measured need to be understand

    WHAT IS THE LAST POINT SAYS SHUNT ELSE WHERE ON THE TRACE, CAN YOU PLEASE EXPLAIN BRIEFLY. Thanks and Regards, Arunmaran - - - Updated - - - Reason for reducing value when i do diode check for the switch. decreasing when i keep on holding negative to switch pad and positive to the ground

    [Moved] ESD diode check for analog switch, value measured need to be understand

    Hi All I have analog switch in my board, when i do ESD diode check the value i am getting is around .3 to .4v for NXP switch(even this is decreasing when i hold it for some time). What would be the reason would be. Thanks and Regards, Arunmaran
