General Purpose Chip Resistors Anti-Sulfuration Features: Applications: * * * * * Automotive application Consumer electrical equipment EDP, Computer application Telecom application High reliability and stability 1% Sulfuration resistant 1,000 ppm Automotive grade AEC Q-200 compliant 100% CCD inspection Lead free products Description: The resistors are constructed in a high grade ceramic body (aluminium 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 extra protective metal film is added onto top side electrodes to protect termination from sulfuration. 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 a Tin (lead free) alloy Protective Layer Laser Trimmed Resistive Element Marking Primary Layer Termination Alumina Substrate Figure 1.

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 235C during 2 seconds. The test condition for no leaching is 260C for 30 seconds. Typical examples of soldering processes that provide reliable joints without any damage are given in Fig 3 Temperature (C) Soldering Condition Time (s) Fig 3.
