RDRAM Rambus DRAM: a type of memory (DRAM) developed by Rambus, Inc. Whereas the fastest current memory technologies used by PCs (SDRAM) can deliver data at a maximum speed of about 100 MHz, RDRAM transfers data at up to 600 MHz.
RECONFIGURATION Upgrading an existing product by replacing subsystems, peripherals, software or cabling.
REFLOW A process to form a solder joint by providing heat to the solder paste.
RELIABILITY AND FAILURE ANALYSIS Capability to determine the root cause of a component or assembly defect or failure as well as to predict the “life” of a board or system. This is usually expressed in terms of “mean time between failures” (MTBF).
REPAIR AND MAINTENANCE Repair, refurbishment, remanufacturing, upgrades, test and burn-in, component debug, field ready pack out, direct ship, RMA control, advanced exchange, DGI management, EC management, data recovery, failure analysis, material recovery.
RETURNS PROCESSING Receiving/parts ID, warranty validation, variance resolution, NTF screen, re-box/re-stock, route to repair/upgrade, scrap/re-cycle.
RF Radio Frequency
RF AND WIRELESS DESIGN Ability to do circuit designs that operate in a range of electromagnetic frequencies above the audio range and below visible light. All broadcast transmission, from AM radio to satellites, falls into this range, which is between 30KHz and 300 GHz.
RFIC Radio-frequency integrated circuit
RH Relative Humidity
RIMM Rambus In-Line Memory Module: This is the form factor for Rambus RDRAM. By comparison, SDRAM is mainly found on DIMM’s, and EDO RAM is usually on SIMMs. RIMM’s require that if you don not fill all RIM slots with RDRAM memory, you must keep the empty slots filled with termination boards to ensure that the high speed Rambus memory signals do not bounce improperly.
RoHS Part of the European Union Directive 2002/95/EC1. This Directive on the “Restriction on the use of certain Hazardous Substances in electrical and electronic equipment”. This directive takes effect July 1, 2006 and bans the use of lead, chromium, mercury, polybriminated biphenyl’s, cadmium and polybrominated diphenyl ethers.
