DescriptionThis desoldering and solder set covers a desoldering vacuum pump and a roll of solder braid. The solder sucker is constructed with premium aluminum bronze and with high pressure vacuum, which allows easy one-handed use and can remove solder from a printed circuit board effectively, perfect for removing solder from PCB through-hole solder joints. desoldering braid. Pure oxygen free copper wire, no clean flux for easy use. Geometrically-precise weave. The solder wick can help clean some residue flux and BGA thermal bonding pad too. If you're experienced or hobbyist trying to fix your monitor or TV, this is a must have tool.Features- Colorz: Silver and blue - Material: Aluminum, copper - Size (Solder Sucker): 18 x 2.5x 2.5 cm/ 7.08 x 0.98 x 0.98 inch (L x W x H) - Size (Solder wick): 150 x 0.25 cm/ 59 x 0.1 inch (L x Dia) - Easy removing. Sturdy aluminum bronze construction and high pressure vacuum, which allows easy one-handed use and can remove solder from a printed circuit board effectively and quickly. - Soldering wick is 2.5mm wide and 1.5m long. With low residue design, this solder braid will help clean spare solder on the pin away to avoid short circuit, especially in small, hard to reach areas. - Perfect for removing solder from PCB through-hole solder joints. - Pure oxygen free copper wire, no clean flux for easy use. Geometrically-precise weave. The solder wick can help clean some residue flux and BGA thermal bonding pad too. - A must have excellent solder sucker which fits nicely in your tool box.Direction of the Desoldering PumpStep 1: Press the plunger down until it is been locked and you will hear a click; Step 2: Make the tip of the soldering iron to the solder joint and allow the solder to become fully liquid; Step 3: Move the tip of the pump next to the molten solder. Move the iron out of the way and immediately cover the liquid solder puddle with the pump's tip. Pull the trigger; Step 4: Repeat this process if necessary.Direction of the Solder WickStep 1: Place the wick over the solder you need remove and then just push the heated soldering iron tip onto the wick; Step 2: Remove the wick once the solder has been absorbed; Step 3: Cut off the used part of the wick; Step 4: Repeat this process if neededTips for the customer:- If you can not get the solder to melt with your iron,apply a little solder to it first - it will help conduct the heat into the existing solder. - Ultimately, this thing is pretty much disposable and limited time use,every couple joints you desolder you should take it apart and clean out the solder to keep it working.
