GLENSOUND'S FACTORY

We are very proud of the fact that here at Glensound Electronics Ltd we actually manufacture in house all our own equipment. We have in house facilities for every process of manufacture from initial design to final EMC testing of products. Our facilities and manufacturing techniques have evolved over the years and our equipment allows us to be equally efficient in manufacturing 1 off designs to mass production of many thousands of identical units.
Below are pictures and brief descriptions of some of our in house processes.   

All our products start life in the hands of experienced team of designers. All aspects of design are done in house, this includes all electronic layouts, software i.e. writing code for DSP, FPGA & Microprocessors and the mechanical design. Once the design is complete both artwork for the panels and for prototype pcbs are plotted onto film using one of our photo plotters.

panel & pcb manufacture
Panels are produced by a photoengraving process onto special anodised aluminium. This has proved over the years to be far more hard wearing than silk screen printing. It also makes it practical to manufacture 1 off panels for custom pieces of equipment.
We have a good range of mechanical plant allowing us to machine just about any piece of metal that is ever likely to be required to be used on audio broadcast equipment.
Side panels are nylon dip coated in house.

Once the artwork has been etched onto the photoengraved panel the panels are cut on one of our CNC routing machines. The panels are then cleaned up by hand and bent into shape on a folding machine.
We use a number of aluminium extrusions which are made to our specific design, these allow us to easily custom manufacture equipment to meet customers exacting requirement.


CNC Routing of Panels
For prototypes and very small production runs we use our in house PCB plant allowing us to make both single and double sided PCBs.
A number of our designs utilise through hole components and these are hand soldered by highly skilled operatives.


PCB Manufacture                Hand placing of components
For larger runs and where end product size dictates, components are placed on PCBs using our own 'Pick & Place' machine and reflow oven. PCBs are then visually inspected using industry standard 'Mantis' viewers and then cleaned up in an ultrasonic bath before being sent to the wiring department.

Two experienced wireman assemble together the PCBs and metalwork, handle all of the interconnecting cabling and get the product ready for test.
Our 3 test engineers between them have nearly 70 years of experience in testing professional audio broadcast equipment. It is their experience and attention to detail that make our products some of the most reliable in the World.


Assembly/ Wiring                   1 off 3 Test Rooms
As well as having a large quantity of specific audio test equipment (audio precisions, lindos (or is the plural lindi?), hewlett packards etc etc) we also have vibration testing and environmental testing facilities.

To comply fully with legislation and to give our customers peace of mind we have a fully screened EMC test room, fitted with a LaPlace horn.
