What is dip soldering?

Dip soldering is commonly used in circuit board production.

Dip soldering is a manufacturing process in which a technician dips objects into a bath of molten solder to secure the parts. The most common application of this technique is in circuit board production, where it can be a quick and efficient method. The heat from soldering can potentially damage parts of the project, and the technician must make sure all components can withstand the heat before diving; normally the design is all metal to avoid this problem.

With circuit board production, solder will adhere to exposed mental components and will not adhere to bare metal areas or areas treated with a chemical to resist solder. Dip welding can be a manual operation, with a technician personally dipping the product, and it is also possible to partially automate it. A machine can grab the circuit board, dip it at the right angle, and hold it in the solder for the correct amount of time before pulling it out.

The dip soldering process is similar to wave soldering, a mass production process that people use to make chips. With wave soldering, it’s all automated and the chips are passed under a constant flow of molten solder material instead of being dipped. This process costs more money to implement and allows people to produce more designs per day, making it suitable for large-scale installations where people need to reduce manufacturing time.

For small-scale soldering, dip soldering can be a useful technique. People don’t need a lot of equipment to assemble it, just a container big enough to dip the projects in, with proper tools to melt the solder so it’s usable. Many companies manufacture the necessary supplies and people can also make their own. For automated setups, slightly larger investments are required to purchase a machine capable of handling the process.

People can learn this and other techniques on the job or during a training program to prepare for a professional career. There are several types of solder available and the technician must be able to choose the correct mix and make other decisions along the way to ensure the final product works correctly. People often inspect the design after dip welding to see if any manual adjustments are needed, such as cleaning excess solder from a contact or discarding a damaged item like marks or distortion from the soldering process.
