(Extreme left and right) Testing of RFequipment; (centre top) assemblyline for RF equipment; (centre above)production floor for RF equipmentand microwave sensorband VSAT ODU Block-Up Converters(BUC), Ultra Slim BUC, high powersolid state power amplifiers (up to100W for Ku-bandand 500W for C-band),up-converters, downconverters,synthesisersand redundancysystems.Complemented by itsproduction, measuringand testing facilities,ST Electronics possesses extensiveexperience in the deployment andmaintenance of these high-poweredRF systems.Upon design confirmation, allproducts go throughContactless switch made by ST Electronicsstringent operations processesentailing system integration, presystemtest, active thermal cycle,QA check, validation test and sealtest before being sent for storage.With advanced technology and acomprehensive range of productionfacilities, such as the Hybrid MicroCircuits assembly and SurfaceMount Technology (SMT) assembly(including PCBA and X-Ray), thecompany’s dedicated productionworkforce (which is IPC610 Class-2and Class-3 standards certified)performs soldering, bonding and partsassembly process to produce highquality RF units.Besides fully equipped to performtuning and precision measurementservices, which covers the entirefrequency spectrum up to 60GHz,ST Electronics also possesses acomplete scope of testing facilitiesthat include signal generatorspectrum analyser, custom-designedautomated testing equipment, highaccelerated stress screening (HASS)and environmental/temperaturechambers, water-proofing, ageing,burn-in and temperature cycling. Inaddition, product integrity is alsoensured by high quality opticalinspection and bond pulltesting. This reducesmanufacturing cycletimes and enhancesproduct quality.ST Electronics complieswith internationalstandards of qualitycontrol for each stage ofthe production line. Quality starts atan early stage from product lifecycleplanning, design specification,to product development, testing,production, revisions and changeorders.With quality management systems,the company is fully capable ofundertaking contract designing andmanufacturing to meet stringentQA testing for microwave sensors.military standards and adhere to strictquality targets and delivery schedules.The array of sophisticated microwavecomponents and communicationsystems that cater to military andcommercial needs includes VSAT forSTAR and MESH communications,as well as digital microwave radio forpoint-to-point communications andlow-cost motion sensing radar for usein security and lighting control.ST Electronics’ commitment to beinga market leader, together with itsnew expanded production capabilities,compels the company to continuouslyinnovate products, including a newrange of compact units: the Ultra Slim20W X-Band BUC, Mini 2W C-BandBUC, 100W C-Band BUC, 40W and16W Ku Band BUC. Small and lightweight, the compact units are idealfor mounting on the feed horn. As noexternal Redundancy Control Unit isrequired, cabling and mounting of theBUCs in redundant configuration isvery much simplified.Compact 40W Ku-Band BUCFor more information, please contactDarene Wong at (65) 6521 7378 or email:darenewong@stee.stengg.comMAY 2011 23
