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.

Perhaps you could add a few washers to the screws that do not make contact with a conductor, evening out the height at which the board sits?

 

Many thanks for the reply.

This is a different form of PCB. The PCB has cable underneath. There is a hole in the PCB. The screw goes through the hole, pierces into the cable and make electrical contact. In this place, where the screw enters the cable, the screw gradually comes out. Is it possible to fix that permanently.?

 

Some photos would be great.
