The resistors are made with a high-grade ceramic body (alumina). Internal metal electrodes are added at both ends and connected by a resistive paste coated on the top surface of the substrate. The composition of the resistive paste is adjusted to obtain the required approximate resistance value, and the value is fine-tuned to within tolerance by laser trimming the resistive layer. The resistive layer is covered with a protective coating. Finally, two external terminations are added. To facilitate soldering, the outer layer of these terminations is a tin (lead-free) alloy. Standard values of nominal resistance are taken from the E24 series for resistors with ±5% tolerance, and from the E24 + E96 series for resistors with ±1% tolerance. The E24/E96 series values comply with "IEC Publication 60063". Due to their rectangular shape and tight tolerances, SMT resistors are suitable for handling by automatic placement systems. The chips can be mounted on ceramic substrates and PCBs. Electrical connection to the circuit is achieved through individual soldering conditions. The terminations ensure reliable contact. The robust construction of chip resistors allows them to be fully immersed in a solder bath at 260°C for 10 seconds. Therefore, SMT resistors can be mounted on one side of a PCB while other discrete components are mounted on the other side (mixed PCB). SMT resistors are tested for solderability at 235°C for 2 seconds. The test condition for no leaching is 260°C for 30 seconds.
