Question about soldering Connectors with eagle PCB

e14 Contributor

Hi,

 

my question is about the two connectors, the 5 screwconnectors and the 6 pin connectors.

 

 

 

As you can see in the brd the connectors meet with their pinhole the red line, which is toplayer.

 

I wonder how to actually solder that.

 

Please look at the eagle3d picture.

 

When i put the connectors on the board would i not have to solder them from the bottom side, as the connector pins go through the board?

My Botlayer is plain GND.

 

 

As the brd shows the red line is top. As its THT and not SMT would i not melt the plastic if i tried to attach it to top, as i would have to?

 

Sry this is my first board in eagle, so maybe its no problem and im just stupid :-)

    thank you very much, so i dont have to worry.

     

    Looking at my 2nd picture, the clearance looks ok, doesnt it?

     

    Another thing i wonder.

     

    As you can see in my 3d picture and the brd i have to staple the 6Pin connector and the Sensor (you can see silk screen of it).

    Problem is this:

    The pins of the sensor r bigger then the pins of the connector. That means this results in bigger drill holesimage

    As you can see in this picture where i slightly moved the connector.

     

    I actually dont need the bigger drill holes as the sensor doesnt get connected into the board but just in the 6pin connector ( and would have a problem with the connector soldering) But i want the big drillholes (not shown in the pictures) for mounting of the sensor and its silk mask.

     

    How can i tell eagle to remove the bigger drillholes shown in the picture, so that id keep only those of the connector?

     

    Do i have to make a new part library for the same sensor, or is there a smoother way?

     

    kind regards

  • It depends on your PCB, If you make your own PCB, this will be a difficult issue.  If you have your boards made from a Board house or Batch PCB, or similar, then the holes will be plated, and you can just solder the bottom side of the board for those parts, because the electrical connection is made top to bottom because of the plating that is done on a professionial made board.  Also since your new to this make sure that you have pads on both side for Through Hole part and that they have good clearance around them.
