Hi Xkwx, Welcome to EasyEDA. Sorry but this is not a bug. Where did you select the BC547B symbol from? Using the BC547B from the EasyEDA Libs, the schematic and PCB pins map correctly: ![enter image description here][1] ![enter image description here][2] ![enter image description here][3] ![enter image description here][4] ![enter image description here][5] Please also check: http://www.onsemi.com/pub_link/Collateral/BC546-D.PDF and SOT54 packaged versions in: http://www.nxp.com/documents/data_sheet/BC847_BC547_SER.pdf (note that pin numbering is reversed on both the symbol **and** the package) * Please note that the TO-92 package is used for thousands of different devices. Please use the `I` Hotkey to edit the pin assignments where necessary: https://easyeda.com/Doc/Tutorial/schematic.htm#Pinmap-Modify-symbol-information [1]: /editor/20170115/587a523e9e348.png [2]: /editor/20170115/587a529a4235e.png [3]: /editor/20170115/587a52b7ee46f.png [4]: /editor/20170115/587a52db20def.png [5]: /editor/20170115/587a5318963b0.png

Yes now it is correct. They made an update a little bit later after I posted this issue.

Before this update PCB Pin C has the number 2 and B the number 1
