How Electronics Yorkshire helped Calrec Audio Ltd

Calrec Audio Ltd, manufacturer of professional audio mixing consoles for broadcasting, regularly uses Electronics Yorkshire’s X-ray inspection equipment to check BGAs. Using the equipment can verify whether or not a short on a manufactured PCB is under a BGA. This allows engineers to either look elsewhere when a BGA looks fine or get the device changed, knowing that the fault will then be fixed.

The equipment also enables Calrec to carry out detailed inspection of prototype PCBs. The majority of the devices that have been inspected are 1020 ball 0.1” pitch devices, however Electronics Yorkshire’s X-ray machine and Ersascopewe have also recently been used to inspect a board with 1152 ball 0.1” pitch devices and many 0.8mm pitch devices.

The markets that Calrec serves dictate that reliability is of paramount importance, as most equipment is used for high profile, live broadcasts for customers such as NBC and ABC in North America, and Sky and ITV in the UK.

The support received from Electronics Yorkshire has assisted us in making fault diagnoses on several occasions, saving engineers time and effort and the company money. Carrying out detailed inspection has helped to give Calrec confidence regarding the integrity of our manufacturing processes when trying out new device types. This support is particularly valuable on brand new designs where we can be confident that any problems arising during prototype testing and development are not due to manufacturing errors.
