CT Production of Poole have ordered a high speed PVA film coating machine for spraying conformal coating onto assembled printed circuit boards.

Up to now, our US partners PVA have been producing only flexible conformal coating spraying machines. These flexible machines have been very popular with our customers and we have sold in excess of 40 units in the UK. However, some customers require higher coating speeds, and PVA’s flexible multi valve systems are very accurate, but slower. This is because you have to change valves within the program to spray into tighter spaces or around difficult keep-out areas.

Film coating is faster. CT Production were looking for a machine that would give them a fast coating speed, and yet they still wanted to maintain a degree of flexibility. Thanks to PVA’s engineering team, we were able to offer them a machine with an airless film coating valve and two further flexible air assisted spray valves. This will become a standard product for PVA which will mean that we can offer customised conformal coating solutions to a wider range of customers from now on. CT Production will be taking delivery of their new PVA machine in May.

Over the past 2 decades, the repair and rework of printed circuit boards with surface mounted devices has become ever more important. As PCB’s become more complex and the value of individual components and PCB’s  increases, it becomes essential to have state of the art equipment for component removal and replacement. Rework of BGA’s is a particular challenge. Our German partners Ersa have been steadily developing and improving their range of rework stations over the past few years. They are a worldwide market leader in this important technology and we are very honoured to be their sole UK distributor and provider of service support.

Ersa’s new Rework catalogue is now available from our Website.
