SBU 2000
Free Standing Small Bench Unit
MPI Bench Unit
The SBU 2000 is a bespoke small bench unit for performing MPI. The SBU 2000 includes AC current flow energising modes as standard with optional HWDC and FWDC current flow and magnet flow (FWDC) modes available. The SBU 2000 sits on a sturdy free standing frame which includes an inking hose and under unit ink reservoir to allow for ink to be reused.
The variable position head-stock use a simple lever operated clamping mechanism to grip components between the U2 type 60mm diameter Copper gauze contact pads. The SBU 2000 is supplied with heavy duty energising foot pedal and fully calibrated with the relevant paperwork as standard.

Plato-3 includes all the features found in the earlier Plato-2 System like auto-regulated current (dial-an-amp), variable shot timer and programmable job sequences but brings to the table new features, full data acquisition and monitoring and a more intuitive interface displayed on a colour monitor.
UV Inspection Booth
For fluorescent MPI processes the SBU 2000 can include a bespoke UV Inspection Booth to reduce ambient light below the 20 Lux demanded by most MPI standards. UV Inspection Booths are usually free standing and fitted with both UV lights and white lights to give adequate background UV light when inspecting with the option of white light for safely loading components and maintenance.
UV Inspection Booths are built around a sturdy steel frame and panelled with either a PVC canvas or steel sheet. Most UV Inspection Booths also incorporate a number of fans to remove heat and prevent build-up of chemical vapours within the booth. Component doors are also common and can be either manual or pneumatically operated.
Bench Accessories
The SBU 2000 can be supplied with a wide range of accessories including threading bars, rigid fixed coils, headstock mounted ‘V’ brackets, mini-jigs and hand-held UV Inspection Lights to aid in inspection processes.
Quality UK Construction
Johnson & Allen pride itself on high quality design and construction which is why the power transformers and coils used in the SBU 2000 are wound, built and extensively tested in-house before they are installed. All Johnson & Allen bench units are designed and manufactured by our experienced team in Sheffield.
