Dear Friends, I am building a small LED PCB. The shape of the PCB is of rectangular in shape. At first I designed it with 2 screws, diagonally opposite in the board to fix the board with cable. The design is, there is no soldering of cable to pcb is involved. Instead, the screw goes into the PCB, into the cable touches the inner conductor of the cable and gives electrical contact. But the PCB does not sit straight. So I have decided to add 4 screws. Noe to make the PCB retain on the board,is there any solutions eg any special screws, any processes? Please suggest me. The dimension I need is M2 length 4-5mm. Thank you. H.Krishnan.
