Higher component and equipment reliability 5. RoHS compliant and lead free products. APPLICATION • Consumer electrical equipment • EDP, Computer application • Telecom DESCRIPTION The resistors array is constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are added at each end and connected by a resistive paste that is applied to the top surface of the substrate. The composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to within tolerance by laser cutting of this resistive layer. The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For ease of soldering the outer layer of these end terminations is Tin (lead free) alloy.

For values up to 9.1 the R is used as a decimal point. For values of 10.0 or greater the first 2 digits apply to the resistance value and third indicate the number of zeros to follow.

FUNCTIONAL DESCRIPTION Product characterization Standard values of nominal resistance are taken from the E24 series for resistors with a tolerance of ±5%, The values of the E24 series are in accordance with “IEC publication 60063” Standard values of nominal resistance are taken from the E24/E96 series for resistors with a tolerance of ±1%, The values of the E24/E96 series are in accordance with “IEC publication 60063” Derating The power that the resistor can dissipate depends on the operating temperature; see Fig.3.

Chip placement can be on ceramic substrates and printed-circuit boards (PCBs). Electrical connection to the circuit is by individual soldering condition. The end terminations guarantee a reliable contact. SOLDERING CONDITION The robust construction of chip resistors allows them to be completely immersed in a solder bath of 260°C for 10 seconds. Therefore, it is possible to mount Surface Mount Resistors on one side of a PCB and other discrete components on the reverse (mixed PCBs). Surface Mount Resistors are tested for solderability at 235°C during 2 seconds. The test condition for no leaching is 260°C for 30 seconds. Typical examples of soldering processes that provide reliable joints without any damage are given in Fig 4. Fig 4.
