Naval Engineering Bulletin • June 2001 FIMA Sydney Circuit Card Assembly—Test and Repair Facility By LEUT Kirsten DAVIS, RAN What is the CCA-TRF? Test Equipment The Fleet Intermediate Maintenance Activity - Sydney (FIMA-S) is responsible to Commander Fleet Maintenance (CFM) for providing intermediate maintenance assistance for rectification of defects beyond the normal capacity or capabilities of ships’ staff. Within FIMA-S is the Circuit Card Assembly Test and Repair Facility (CCA-TRF), commonly referred to as the ‘FIMA PCB Lab’. It is the primary facility for Intermediate Level test and repair of Circuit Card Assemblies (CCAs). Capabilities of the CCA-TRF Last year, the FIMA CCA-TRF received approximately 200 analogue and digital Circuit Card Assemblies (CCAs) for testing and repair. Most of these CCAs came from the Logistics Support Organisation (LSA), directly off ships (on a Maintenance Control Record (TM200) basis) and from system trainers on Garden Island. Recently, the lab has also undertaken an Ordnance Alteration (ORDALTS) and Report of Defective Material or Design (TM179) action for the LSA and Mobile Operational Technical Unit (MOTU). Located on Level 3 in Building 79 at Fleet Base East, the CCA-TRF also operates as a ‘drop in’ centre offering troubleshooting assistance for urgent repair work for ships alongside. There are over 1400 Test Program Sets (TPSs) that support CCAs from numerous systems including Mk-92 Fire Control System, Mark 15 Close-In Weapon System (CIWS), SPS-49 Radar and Peripheral Control Systems. The CCA-TRF uses these test programs to diagnose and pinpoint the location of possible components that may be causing the CCA to fail. Two types of automatic test stations are currently used by the CCA-TRF to functionally test the CCAs. These are the M3-ATS and the Genrad 2225. Both these stations run test programs that determine whether or not a CCA is serviceable. If the CCA is non-serviceable a list of possible faulty components is generated which are then tested individually to isolate the faulty components. The M3 Automatic Test Station is a freestanding unit that contains a suite of VXI and GPIB instruments. All TPSs for the M3-ATS are developed in TestBasic and are used to control the instruments to exercise the CCA with predetermined stimuli and then compare the measured response against the expected response. The RAN’s main method of in circuit testing is the GenRad 2225. The Genrad 2225 is a digital circuit tested with limited analogue capability. It was first introduced in to the RAN in the early 1980s and has proved to be a reliable and effective test station. TPSs that run on this station can isolate to individual component level. FIMA Sydney CCA-TRF is the also only designated Australian Defence Force repair agent for the Genrad. The USN no longer supports the Genrad or by Genrad Inc. and as the predominant user of the Genrad, the RAN provides user training and maintenance, repair and calibration actions on the Genrad for both the RAAF and the Army. Following fault detection on an automatic test station, diagnostic tools are used to further isolate the faulty component. The RAN’s most commonly used diagnostic tools are the Huntron range of instruments including the Huntron 5100DS. The 5100DS interfaces with a computer, where the signature of a component being tested is compared with a signature stored in a computer database. These stored signatures are part of a signature set for the entire CCA, which is known as a 22
