Products, Services and Facilities

  We design products for you, the customer.

 

   We can then make the product for you, or we will provide full documentation for you to manufacture it yourself.

 

   We have a range of test facilities to help you solve development problems and improve your product.

 Research, Development and Test Facilities

PCM uses computer-aided design including circuit simulation tools in the various phases of the engineering process to produce a rapid and flexible response to our customer requirements.

Schematic capture and PCB design is normally done in-house using Altium Designer to create the optimum layout for switchmode power supplies and for low noise analogue circuits.

Laboratory facilities include direct data acquisition from instruments to computer for data storage, processing and presentation of test results.
