Spouted Bed Electrode SBE Technology
Technic’s Spouted Bed Electrode (SBE) is a new, patented method of electroplating small components such as:
- Electronic connectors
- Chip capacitors
- Chip resistors
The SBE plating system replaces a 4 x 6 inch barrel with a patented SBE chamber. The load size is from 50 to 500mls and uses significantly less conductive media.
Technic SBE Advantages
A variety of parts with dimensions no larger than 0.25 inches (6.35 mm) in any one direction can be plated in the SBE system with a significantly reduced amount of conductive media, reducing costs and increasing production.
- No Moving Parts
- Improved Part-to-Part Thickness Distribution
- Lower Operation and Materials Costs
- Reduced Coupling
- Increased Production Speeds
- Reduced Maintenance
How it works
The SBE plating chamber’s unique design provides for a rapid circulation of the parts over the cathode current feeder without the use of any mechanical movement. Plating solution flow rates carrying the parts through the chamber are exceptionally high (up to 60 liters per minute), thus ensuring that the parts are always plated in “fresh solution”, irrespective of the configuration and size. Both of these attributes result in greatly improved part-to-part thickness distribution and a significant reduction in part-to-part coupling.
The SBE’s narrower thickness distribution curve allows the SMT producer to target the average plating thickness of a given load much closer to customer minimum thickness requirements than can be done in standard barrel plating equipment. The SBE unique processing approach offers greatly increased production speeds while satisfying the most stringent quality control standards. Another advantage of the SBE plating chamber is the elimination of tin and/or nickel deposits in the screened area of the chamber. Unlike a barrel, where plating takes place when the parts are on the barrel screens, the SBE screens are located in a non-plating area. This greatly cuts down on the maintenance of the plating chamber.
Our 1-6 Model consists of two plating tanks (one nickel, one tin) with a two station rinse after each process. The unit is constructed from polypropylene, mounted to a stainless steel base with leg levelers. The SBE comes complete with pumps, filters, rectifiers, piping and exhaust outlet and is equipped with two SBE chambers.

Our 2-6 Module provides double the production capability by providing a second row of stations in each tank. The 2-6 Model comes equipped with four SBE chambers.
SBE Automatic Systems
SBE Systems is available in semiautomatic and fully automatic. The dual hoist system show here with consists of six nickel stations, dragout, cascade rinse, six tin stations, dragout and cascade rinse. In both automatic and semi-automatic SBE systems, the hoist moves a flight bar holding two SBE chambers.
