PASTEMASK_TOP / PASTEMASK_BOTTOM for through-hole PIP (Pin in Paste) reflow slodering

vivanov

I cannot produce  PASTEMASK_TOP and PASTEMASK_BOTTOM for through hole components even if I define its geometry in padstack design PASTEMASK_TOP and PASTEMASK_BOTTOM, but I can produce pastemask for SMD.

It looks like PASTEMASK is suppressed for through holeparts even if it is set in padstack (not NULL). I can bypass it by using FILMMASK in artwork instead, but is any way to have PASTEMASK produced for through hole parts, because it is really needed for PIP (Pin in Paste) reflow soldering, as described below:

  • One method I've used is to add shapes on PACKAGE GEOMETRY/PASTEMASK_TOP(or BOTTOM) at the symbol level.

  • I don't have this issue and can define PASTEMASK_TOP / BOTTOM for a through hole pin and it is produced in the artwork without issue. Are you sure you have defined the PTH pin correctly and then updated the design ? Can you see the PASTEMASK_TOP pad on the canvas ? Is it defined in the artwork ?

    I do not see anything for PASTEMASK_TOP / BOTTOM for through hole pins on the canvas or artwork

    I can define, update, and see FILMMASK _TOP / BOTTOM, or Soldermask_TOP/Bottom for the same pins. Is any big difference between PASTEMASK and Soldermask or FILMMASK?

     

  • What exact version of tools are you using from Help - About? Are you sure you have turned on Pin/Pastemask_Top / Pastemask_Bottom and the color is set to something you can see (i.e. not black). They pastemask filmmask and soldermask are just a different layer that you specify....

  • Thank you very much, I solved: visualizing Pin/Pastemask_Top / Pastemask_Bottom works. Before I tried only Board_geometry/Pastemask_Top and Pastemask_Bottom, which worked for fiducials.

    Please also help me to visualize thermals. I set them is "Setup\Design Parameters ...\Display\Enhanced display modes\Thermal pads", but can see them only in Gerber artwork. Which class and subclass I need to use to see thermals in negaive planes?
