Thunder Precision Resistor's standard of acceptability of solderability of melf resistors
MELF (metal electrode lead-free surface) resistors can be soldered by reflow and wave soldering. The welding effect and strength shall meet the corresponding requirements of this standard extracted from ipc-a-610f and the experience summary of actual test results made by Thunder Precision Resistor Co., Ltd.
In order to ensure the welding strength and the heat dissipation demand during the long-term use and improve the reliability of the of the resistors , the soldering pads designed on the circuit board should refer to the size requirements in the table below.
