What is a pcb screw terminal

What is a pcb screw terminal block?
As the name suggests this is a electrical connector where a wire is held by the tightening of a screw. Printed circuit board (PCB) terminal blocks are specially designed with a copper alloy pin of suitable size and length and can be inserted in printed circuit boards to be soldered to allow electrical signals and current to flow to and from PCBs and electrical equipment. Some designs provide features that allow the flow of molten solder to endure a better connection between the circuit traces of the board and the electrical equipment which is meant to be controlled or fed appropriate power.
Are terminal blocks safe?
Yes, if installed currently. Once you have made all the connections to the terminal block, test your equipment to make sure it works correctly. Afterward, check the terminal block and the connections to make sure that there is not excessive heat build-up and that the wires are still securely in place.
Hitaltech produce a wide range of wire to board connectors which includes a huge range of PCB terminal blocks including screwless and traditional screw block. These are all produced in a wide range of pitches and angles.
