When soldering patch components by hand, the trouble is how to place the small chip resistor.
At this time, the traditional dice are not enough, and a vacuum pen can greatly improve work efficiency.
Let us work together today to make a cheap vacuum pen, like this:
Materials and components
A small fish tank pump (pay attention to buy a quiet point)
One disposable syringe (small, not too big)
One plastic hose (small, the key is soft)
A small section of silicone tube (ideal size: outer diameter is slightly larger than the inner diameter of the syringe body, the inner diameter is slightly smaller than the outer diameter of the plastic hose)
tool
Electric drill
The production process is simple:
We want to use the suction of the intake end of the aquarium pump, so fix one end of the hose to the inlet of the aquarium pump, and use a little glue if necessary.
The other end of the hose is covered with a silicone tube and then fixed to the tube of the syringe, which is also sealed.
Then use a power drill to open a small hole in the syringe body, put a piece of silicone tube, and seal the edge.
Finally, the needle of the syringe is properly bent, and a vacuum tweezers is ready. It can be done in a dozen yuan.
The method used can also be simple:
Turn on the electric pump, align the patch components, and block the silicone tube on the side with your fingers. The small patch is sucked up.
After moving to the appropriate place, release your finger and the small patch will be put down.
The effect is not bad, if you always solder the patch components, you deserve it.
