The Melting point of solder is the temperature at which the solder changes its state from solid to liquid. The typical melting point of the general solder is in the range of90 to 450 °C (190 to 840 °F | 360 to
Rosin (R) Flux: It has only rosin and is the least active. This type of flux is mostly used for surfaces that are clean. It leaves virtually no residue after soldering. Rosin Mildly Activated (RMA) Flux: It has sufficient activator to clean the solder-coated or plated lands and ...
Composition of a typical mini-MELF board While there are many types of custom mini-MELF boards, most share common design elements, components, and materials: PCB substrate The PCB substrate forms the base of the board providing mechanical support and electrical connectivity. Common materials include...
Not as it is today when many of us aspire to Chanel for all the wrong reasons. In the fifth decade of the twentieth century soaps and hairsprays smelled of the influence of Chanel in America. It was as if the thought of Paris glamour could be found with in the bubbles that floated ...
From a mechanical integrity standpoint, mixing a highly reactive metal (aluminum) with a corrosive electrolyte solution is a delicate proposition; errors in electrolyte composition can result in premature failure, as evidenced by the “capacitor plague” of the early 2000’s. Another shortcoming of ...
PCB designers can determine when it is the optimal finish choice. Although not the cheapest option, the excellent technical properties of electroless nickel immersion gold ensure it will continue seeing widespread use protecting bare copper and enabling robust solder joints across countless electronic syst...
Alpha brasses are single-phase alloys with a composition of 55-65% copper and 35-45% zinc. They exhibit a face-centered cubic (FCC) crystal structure. Technical Specifications Alpha brasses are known for their excellent cold workability, which is a result of their ductility. They offer good...
The different actions required of a flux imply different ingredients in its composition: solvent, activator, vehicle, and other additives. Solvent A solvent is needed to dissolve activators, the vehicle, and other additives, while evaporating during the preheating process, or if you forget the jar...
What is a calorimeter? Name the material of which it is made. Give two reasons for using that material. Heat Energy: Heat energy can be defined as the amount of heat generated due to the motion of the tiny particles. Heat energy is the transfer fro...
Carbon Composition Resistor Wire Wound Resistor Thin-Film or sheet Resistor Thick-film or Sheet Resistor Carbon Composition Resistors A common solid resistor is composed of a blend of insulating filler, resin binder, and powdered or granulated graphite or carbon. The real resistor’s resistance is ...
