Physical properties

E-blocks can be mounted onto a metal back-

plane to form a completely rugged system.

To facilitate this each E-block is fitted with 4 

off 3mm holes spaced at multiples of 20mm. 

M3 bolts can be used to mount the E-blocks 

onto a backplane which has 4mm holes on a 

regular 20mm grid.   The spatial relationship 

between the mounting holes on the 

backplane, the holes on the E-blocks and the 

spacing of each D-type plug and socket on 

the E-blocks are such that each E-block will 

fit into another, and yet still be mountable on 

the backplane.

Mounting options for backplanes

There are several options for mounting 

E-blocks on a backplane depending on your 

circumstances:

• Temporary mounting with pillars

Custom moulded circuit board pillars are 

available which allow you to loosely mount 

boards to the backplane. This is ideal if you 

are working through a course and frequently 

reconfiguring the E-blocks system to give 

yourself experience of different systems. Note 

that these pillars are very tight initially but 

soon loosen up.  This is shown in profile in 

Figure 5.

If you are reconfiguring your E-blocks system 

less frequently then we suggest that you 

use M3 bolts on all your E-blocks and that 

you use a metal backplane to mount them 

on.  The E-blocks can be mounted on the 

backplane with M3 self locking nuts - these 

will keep the bolts secured onto the circuit 

board and will act as spacers to keep the 

board clear of the backplane.  (See Figure 

6).  When you want to move the system 

around then one or two additional nuts 

behind the backplane will ensure your 

E-blocks stay in place. For best results with 

this mounting technique you should attach 

the bolts and self locking nuts and then 

slacken off the nuts by a quarter turn - this 

allows the bolts a little movement in the PCB 

mounting holes and makes them easier to 

take off the backplane. If you are concerned 

about preserving the painted finish of your 

backplane then you can substitute the steel 

bolts with nylon ones. However we have 

found the powder coating of the backplanes 

is sufficiently strong not to warrant this.

Using E-blocks on the bench

You do not need a backplane to use E-blocks 

- you can simply connect them together on 

the bench. In each E-blocks package you will 

find a four small rubber feet to facilitate this. 

These will provide a degree of protection for 

your E-blocks boards and will help prevent 

shorts from tinned copper wire and other 

metal objects on the bench. The disadvan-

tage of this is that your E-blocks system will 

not be secure and that the connectors will 

be under more stress as the system is moved 

about.
