Hi to all, I have recently joined the list and enjoyed lurking in the shadows for a little while. However, the company I am working for has now decided to design double sided mixed technology P.W.B.s for manufacture. Having had little experiance with this, I would apreciate it if anyone out there could steer me in the corrct direction regarding some text books or articals on it...... Thanks.
