Colour trends for PCB test points and
terminals
Traditionally, black has always been the most popular colour for William Hughes's PCB test points and terminals but for the first time, demand for red test points has overtaken that for black.

When a wire former was asked to quote for the supply of a bent wire assembly for car seats, its engineers re-designed the component to speed assembly on the production line.
The full range of test point colours manufactured by William Hughes, in order of popularity, is red, black, white, yellow, green, blue, pink and brown.
The glass bead on the test point, made of boro silicate sintered glass, provides the colour and gives a high resistance to thermal shock, with the wide choice of colours enables the individual test points to be quickly identified when installed on the board, said the company.
Each test point also features a large loop for probe attachment and bowed legs for insertion into the board without damage to a through plated hole, the phosphor bronze spring strip being solder tinned to ensure good electrical contact, said William Hughes.
Three sizes are available - large Type 100 for 1/16 inch board thickness and 1.32mm hole size, small Type 200 also for 1/16 inch boards but for 1.0mm diameter hole and long legged Type 300, with its 3.6mm legs and 2.1mm loop.
Popular as terminals too, the test points are also ideal as mounts for components that may need scheduled replacement, or for elevating heat-generating elements above the PCB surface, added the company.
Test points can be shipped in large or small quantities, bagged as required, for both prototype and volume production.
For applications that require a test point style outside the standard range, there is a choice of special colours and a custom design service is also available.
