I've bought this box for my PCB. There are several holes on it, but the holes are closed at one end. How can I design my PCB to be fixed in this box? Should I add hole for screws on my PCB? I can puncture the box, but it won't look good!

I don't know the application of these holes.

    \$\begingroup\$ Given they are square holes, I presume they are designed for some form of push fit captive nut. Or just some self tapping screws. \$\endgroup\$

I would expect the documentation for the box to specify a screw size that would cut its own threads in those holes (the box might even come with appropriate screws).

You would place holes in your PC board to match the post positions in the box.

    \$\begingroup\$ They may be intended for self-tapping screws, but the plastic is probably soft enough that normal screws will work. \$\endgroup\$

Design your PCBs to fit into the box.

  • \$\begingroup\$ @DerStrom8 I don't think so, he does not asked how to secure. \$\endgroup\$

  • \$\begingroup\$ @DerStrom8 You're true. I meant how to "secure" the board. Also, it is simpler to put holes on the board rather than changing the board shape from its rectangular form. \$\endgroup\$
