Precautions for use of tin absorber.

The absorber is a tool for repairing electrical appliances, which is used to collect soldering tin when disassembling the electronic components of the welding disc.There are manual and electric.It is more difficult to dismantle and dismantle the parts, especially the large scale integrated circuits. It is easy to destroy the printed circuit boards and cause unnecessary losses.The simple sizer is manual, mostly plastic, and its head is often made of high-temperature plastic because it is often exposed to high temperatures.

There are several things to note when using the siphon:

1, needs to be checked before use suction tin seal are in good condition, check method is to absorb tin rubber handle on the card master piston position, both of the gas in the cavity in the body to pressure, and then use finger belly blocked suction tin suction nozzle holes and convex point button, if the piston is not easy to play in place that the sealing effect is good, and the sealing effect is bad, only good sealing effect of tin when using absorption can effectively remove solder joint and smoothly desoldering.

2. Select the nozzle aperture of different specifications according to the thickness of the components in the circuit board, and the diameter of the standard nozzle diameter is 1mm and the outer diameter is 2.5mm.If the spacing between the components is small, the inner hole diameter is 0.8mm and the outer diameter is 1.8mm.If the welding pan is large and the component lead is thick, the suction nozzle with diameter of 1.5 ~2.0mm can be selected according to the specific situation.Tin absorber

3. After the suction nozzle of the absorber is used for a long time, the effect of tin can be changed, and new suction nozzle needs to be replaced in time.Tin absorber

4. Before welding, it is necessary to dip the absorber into a bit of rosin to improve the fluidity of the solder and enhance the absorption effect before each contact.Tin absorber

5, the suction nozzle welds contact time is a bit long, after the solder melts, centering on the solder pins, hand to draw a circle clockwise again after the press of a button for soldering tin bulge absorption gettering.Tin absorber

6, if the gettering solder, solder tin solder without complete melting using suction apparatus gettering, can cause components had residual lead solder, this situation can not continue to use suction tin gettering, or use suction drain the residual soldering tin belt.Tin absorber

7, tin is used a few times after soldering could strong cavity or suction mouth stuffed with, then remove the cavity in the body after soldering in work, no side suction welding machine doesn’t work, general cleaning method is to suck tin suction nozzle removed and cleaned up.Tin absorber

These are the seven items that need to be paid attention to in the use of of tin absorber.
