  • 8.3.3.3 Visual inspection 3:Minimum end solder width of MELF resistors after reflow soldering minimum end solder width of melf resistors after reflow soldering in larger than 50% of the diameter of the resistors or larger than 50% of the width of the solder pad. the wider the solder width the better the solder strongth. the most important of the the requirement of getting wide solder width at the end of melf resistors is the sufficient amount of tin paste on the solder pads. minimum end solder width of melf resistors after reflow soldering in larger than 50% of the diameter of the resistors or larger than 50% of the width of the solder pad. the wider the solder width the better the solder strongth. the most important of the the requirement of getting wide solder width at the end of melf resistors is the sufficient amount of tin paste on the solder pads.

  • Thunder Precision Resistor Co., Ltd. disclosed the process and preparation methods of making a new kind of UHF RF resistors: (1) Take a certain mass of nano silicon carbide with a particle size of 20nm ~ 50nm and disperse it in 95% ethanol with a mass multiple of 5 ~ 8 times, and then add nano alumina with a particle size of 20nm ~ 50nm with a mass of 2 ~ 3 times of nano silicon carbide to fully disperse it; (2) Add silane coupling agent dl602 with 2% ~ 3% mass of nano silicon carbide, fully stir until the system thickens, and then add organic Polyborosilazane iota-9120 with 0.3 ~ 0.5 times mass of nano silicon carbide to fully disperse; (3) in air atmosphere, the mixture of step 2 (step 2) was desiccant and cured by spray drying method, and the modified filler was prepared.

  • There are many different types of Resistor available which can be used in both electrical and electronic circuits to control the flow of current or to produce a voltage drop in many different ways. But in order to do this the actual resistor needs to have some form of “resistive” or “resistance” value. Resistors are available in a range of different resistance values from fractions of an Ohm ( Ω ) to millions of Ohms.
