Desoldering | Soldering Basics | Soldering for Beginners

Summary

This video tutorial demonstrates effective methods for removing soldered parts from a circuit board, focusing on two main techniques: using desoldering wick and a solder sucker. The presenter explains how to properly heat solder joints and utilize flux to enhance the process. A clever trick is shared, involving adding solder to connect leads for easier removal. Caution is advised regarding potential damage to copper pads, emphasizing careful technique to avoid pulling them off. Viewers are encouraged to share their own desoldering tips and tricks, fostering a community of shared knowledge.

Takeaways

• 🔧 Use a solder wick (desoldering braid) to absorb solder by placing it on the joint and applying heat with a soldering iron.
• ⚗️ Flux can be used with solder wick to enhance solder absorption when it's not soaking in properly.
• 🔄 A solder sucker is an effective tool that uses a plunger to suck up melted solder when pressed.
• 🔥 Ensure the tip of the solder sucker is close to the solder joint for effective suction during removal.
• 🛠️ Stuck leads can be loosened by directly heating them with a soldering iron.
• ⚙️ Connecting leads with additional solder can help in removing them simultaneously when heated.
• ⚠️ Excessive heat can damage the copper pads on the circuit board, potentially pulling them off.
• 🩹 If a copper pad comes off during removal, it can be replaced but may require compensatory adjustments.
• 💡 Practice is key; it may take several attempts to effectively desolder components using these methods.
• 📣 Share your own desoldering tips in the comments to help others learn.

Q & A

What is the purpose of the soldering wick?

The soldering wick, also known as solder braid or desoldering braid, is used to remove solder from a circuit board by absorbing it when heated with a soldering iron.

How does flux assist in the desoldering process?

Flux helps improve the flow of solder and allows the solder to be absorbed into the wick more effectively, ensuring better desoldering results.

What is a solder sucker and how is it used?

A solder sucker is a tool with a plunger that is used to suck up molten solder. You heat the solder with a soldering iron and then activate the sucker to remove the solder.

Why might it take multiple attempts to remove solder with a solder sucker?

It may take several tries because the solder might not completely melt or be drawn into the sucker on the first attempt.

What technique can be used to help remove parts that are still stuck due to residual solder?

Heating the leads of the part with the soldering iron and gently pushing them can help loosen the part from the circuit board.

What is the advantage of adding solder to leads before removal?

Adding solder to connect both leads allows them to melt simultaneously, making it easier to pull the part off the board.

What potential damage can occur when desoldering a part?

Excessive heat or pulling on a part while the solder is still hot can cause the copper pads to pull off the circuit board.

What should you do if a copper pad comes off during desoldering?

If a copper pad comes off, you can still replace the part, but you will need to find a way to compensate for the missing pad, such as using a jumper wire.

Is it normal for some solder to remain after using these desoldering methods?

Yes, neither the solder wick nor the solder sucker removes 100% of the solder, so some may still remain.

What should viewers do if they have additional tips for desoldering?

Viewers are encouraged to leave comments sharing their own tips or advice for desoldering and removing parts from circuit boards.
