In the latest edition of InTheMail, I unbox and review a treasure trove of electronics tools and gadgets from AliExpress and Amazon. From high-quality pliers to versatile USB-C connectors and even a unique IR pre-heater, this video is packed with valuable insights and recommendations for hobbyists of all levels.

Kicking things off, I share my honest thoughts on a set of pliers that failed to meet expectations, followed by a handy pair of scissor-type cutters perfect for trimming heat shrink and enamel wire. Next up, a carbon fiber spudger adds an anti-static and ESD-safe option to my toolkit. The video also showcases the compact and open-source olmBoard modules, featuring impressive specs like a wide input voltage range and low power consumption.

USB-C connectors, a magnetic rotary position sensor breakout, and a digital speaker amp board are also highlighted. For those working with DC motors, I review breakout boards for the DRV8871 H-bridge driver, offering overcurrent and over-temperature protection. Practical accessories like a tactical shoulder strap, corkscrew bottle opener, and wetsuit hanger are also covered.

One standout item is the IR pre-heater, which has revolutionized my soldering and desoldering workflow. By pre-heating PCBs, I can minimize stress on surrounding components and achieve better results, especially for double-sided or heavily populated boards. Finally, I explore the potential of syringe filters for cleaning and reusing ultrasonic cleaner liquids more effectively.

Mastering PCB Cleaning with an Ultrasonic Cleaner! | Voltlog #467

Keeping your Printed Circuit Boards (PCBs) in pristine condition is crucial for ensuring optimal performance and longevity. While no-clean solder products are available, many fluxes and soldering materials leave residue that can corrode components, cause leakage currents, and compromise the overall aesthetics of your projects.

Fortunately, an ultrasonic cleaner offers a convenient and effective solution for thorough PCB cleaning. In this comprehensive guide, we’ll explore the benefits of using an ultrasonic cleaner, essential safety precautions, and a step-by-step process for achieving impeccable PCB cleaning results. The principle behind ultrasonic cleaning is a phenomenon called cavitation.

High-frequency sound waves create rapid pressure changes within the cleaning solution, generating countless microscopic bubbles that form and implode. As these bubbles collapse near the surface of the PCB, they release intense energy, dislodging dirt, contaminants, and residue from even the most hard-to-reach areas.

Before diving into the cleaning process, it’s crucial to observe a few safety precautions. Firstly, never run an ultrasonic cleaner dry, as it can overheat and damage the unit. Secondly, avoid using flammable liquids, as they pose a fire risk when heated. Lastly, consult component datasheets to ensure that the parts can withstand ultrasonic cleaning and submersion in liquids.

To achieve optimal cleaning results, choose a high-quality ultrasonic cleaner like the VEVOR Ultrasonic Cleaning Machine, which offers adjustable temperature, cleaning time, and ultrasonic power settings. Pair it with a suitable cleaning solution and deionized water for best results. The cleaning process itself is straightforward: fill the cleaner with the appropriate solution, submerge the PCB, and let the ultrasonic waves work their magic.

Post-cleaning steps include rinsing the PCB in deionized water and drying it with compressed air. One of the significant advantages of ultrasonic cleaning is its ability to dislodge residue from hard-to-reach areas, such as between component leads and under IC packages, ensuring a level of cleanliness unachievable through manual brushing alone.
