With PCB vias extend to every copper layer. Actually, there is no way to make a via one layer only. This also applies to pins, too. > This is important for me because I will soldering the STRAIGHT PIN > HEADER on my pcb so so I will solder it on booth sides of the pcb, > like on the web page mentioned bellow. Do you intend to send your files to a factory for production? If so, you don't have to worry about the sides at all. Metallized pins and vias are the norm these days. That is, the holes receive an inner lining of metal. If you solder the pin on the bottom layer, the ring on the top layer will automatically be connected, too. If you etch and drill the layouts yourself there will be no automatic connection from bottom ring to top ring. It would not be easy to solder the pins of the header to both rings either. The black insulating stuf blocks access to the ring. In this case I'd recommend to add actual vias somewhere midway between button and header. The via would be populated with a piece of wire. Hope, this helps,=20 ---<)kaimartin(>--- --=20 Kai-Martin Knaak Email: kmk AT familieknaak DOT de =C3=96ffentlicher PGP-Schl=C3=BCssel: https://keyserver.ubuntu.com/pks/lookup?op=3Dindex&search=3D0x7B0F9882 --Sig_/kzFLzBFgchVwAVLLP2wKufq Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEyAypwA/y2l/nFU8PwTqkzHsPmIIFAl0iXdwACgkQwTqkzHsP mIJvfQ//RqnFlYtZkn3fnpwoEVQ5xc65qXjlm2oj7lWNwZ8xJ7iPGIKAmJXgo9jx lS6it+dsWqOprQryETWowzhxl1j5tZ4caFLpjL04qkaGUlz4ZC7wUxnA+V/ab1Wo A8+hl+mOsDf9UHFDyz+T0Xd4lA1lQiJr7mhPMDRLVNKhQ3QS5/jXu6rc82oSjMnS L4hB2cs3RxOhpOUSYTeNn9ANFz1mBVMQHJRE/Iw5kJnTHILVQYH8BEvFMbke1kJ6 K1KW7dHVPF0OWc6rAjaBJsdovMSVUa6EXYKize43d7zPWuuNuPSc5Q6AFf78g7NK fvP7u5FKlFS1ExLFg/pfMBAY6bJPyeP/4bBsnzj2zwX1Ko1tckuDKnVhF/veEp7y xiN1P4/E4bEmSqA10vx+JHOJOrlmRIs6gQTfJhCpuy8qT6kmQ7ldVyUGQy72we/Z ccIPcNFpKIdz3e2owqvhlPDwEU1lBzazV0hS36rSyAs6OrP4P4a3bZtnSEg9JugY 8/G2J6TJ/EysJ5qgBsFT/f8H32fe6rpNOtifhjQveGRbU5tBApfiWI8pmh/Xiiod J4Hs7LBSAmi4nPLw/dOK0DwGunqNGUkfy7wMnMRPg66ZCpO7RA6mRnk6d3oDlYvN XAUP6xYTxT7Td1+9nIppIPymjyIj4lRrAIXEzHERoMDWMeANW14= =lAU2 -----END PGP SIGNATURE----- --Sig_/kzFLzBFgchVwAVLLP2wKufq--
