However, it must find that its use is almost essential for welding certain surface component CMS. Or to be more precise to remove excess solder deposited on the pins of the components. This is especially true for integrated circuits whose pins are very close as the IC SOIC or smaller size.
For this use a 2.0mm or 2.5mm braid is perfect. Dabsorption its capacity is reduced, but given the small amount of solder to be removed is enough. Moreover, this small size is a big advantage for fast-mounted temperature braid which prevents prolonged heating and overheating conduction of harmful components to the component itself or its plastic housing.
Like most consumables, it is more profitable to buy the desoldering braid quantity. If you plan to solder SMD components seriously, an amount of 15 to 30m is the most economically advantageous, especially since, unlike tin solder is a product that keeps well.
