There is no proper soldering iron temperature just for a given type of solder-the iron temperature should be set for both the component and the solder. When soldering surface mount components, a small tip and 600F (315C) should be sufficient to quickly solder the joint well without overheating the component.here is no proper soldering iron temperature just for a given type of solder-the iron temperature should be set for both the component and the solder.

Take Magnesium Supplements. 1  The RDA (the minimum amount needed) for magnesium is about 300 mg a day. Most of us get far less than 200 mg. 2  Some may need much more depending on their condition. 3  Most people benefit from 400 to 1,000 mg a day.
In the United States, however, the average daily magnesium intake is about 320 mg for men and about 230 mg for women, or 24% and 28%, respectively, below the RDAs. A recent study showed that elderly American men and women consume only about 225 and 166 mg/day of magnesium, respectively, or 46% and 48% below the RDAs.or adults aged 31 or older, the Food and Nutrition Board of the Institute of Medicine has set the Recommended Dietary Allowance (RDA) for magnesium at 420 mg/day for men and 320 mg/day for women (for adults aged 19â30, the figures are 400 and 310, respectively).
