Test point beads support circuit-board components

William Hughes has brought out test point beads for design and development engineers working on prototypes or small-quantity printed circuit-board production.

The hollow beads provide a quick and flexible method of insulating and supporting components such as potentiometers or semi-conductors on a printed circuit board.

Test point beads are ideal for isolating resistors or the exposed legs of individual components.

They can also be used as mounts for components that may need scheduled replacement or for elevating heat-generating elements above the PCB surface.

There is a choice of two sizes and eight standard colours, which can be used to colour code components as they are installed on the board.

There is no measuring or cutting required as the beads can simply be used in multiples and built up to the required length.

Test point beads can be shipped in large or small quantities, bagged as required.

Test point beads are ideal for use alongside William Hughes test points, which provide a quick and reliable connection to test points on a printed circuit board.

The phosphor bronze spring strip is bright acid tin-plated and features a large loop for easy probe attachment and bowed legs for quick insertion into the board without damage to a through plated hole.

A special glass bead gives a high resistance to thermal shock.
