Electronics Workshop

The Electronics Workshop is located in B013 on the Ground Floor of B Block and is accessed under the bridge that links the Science Concourse to the E Block Lecture Theatres

The workshop main hours are from 9AM to 5PM and you should contact Rod Wesson or Marcus Grant (located in the mechanical workshop) to discuss electrical or electronic testing and repair and fabrication of specialist equipment. Please email r dot c dot wesson at warwick dot ac dot uk first as we are not in the workshop at all times.

The departmental Electronics Workshop undertakes a range of testing and repair work of portable electrical and electronic equipment including instrumentation and instrument controllers.

Specialist equipment can also be designed and fabricated in collaboraton with research groups when there are no commercially available alternatives.

We have the goal of providing an efficient service. We welcome feedback and appreciate comments on the service that you have recently received.

Design

Here are some designs from the workshop

Six channel custom column heater with 3D printed components.

New design work

For new design work we have a selction of software to assist us...

For PCB design we have ISIS schematic capture (circuit design) and simulation using SPICE models. This links with the ARES PCB layout software

For CAD and artwork design we use Coreldraw 15.

For programming the PIC microcontrollers we use on some of our designs we use MPLAB.

We also have a CEL Robox 3D printer!

We are currently working on improving what we can offer and the workshop is been refurbished to reflect this.

Repair

Ika hotplate repair. Common fault on old hotplates when the relay fails it can burn a hole through the circuit board. This has been milled out and new board and traces fitted. process takes less than two hours for a £600 hotplate.

For rework we use standard soldering irons and a hot air pencil as well as various hand tools.

We also have thermal imaging capabilities. These pictures show a working furnace and one with faulty elements that were in use on the 3rd floor.
