Printed circuit boards (PCBs) are at the heart of every electronic device — from smartphones to robots. But even the most well-made PCB can fail if it’s not cleaned properly. Dirty boards can lead to performance issues, short circuits, or even total failure.
At Tokimeku, we’ve seen how easily these issues can arise — often due to a few common cleaning mistakes. That’s why we carry a wide range of cleaners and chemicals to help you help you avoid these pitfalls and choose the right tools for the job.
Common mistakes include:
Using The Wrong Cleaner
Generic cleaners like acetone or alcohol may damage PCBs or leave residues. The safer and more effective approach is to use a cleaner specifically formulated for electronics. The Techspray G3 Flux Remover is designed to remove stubborn flux and grime while being safe for sensitive components. It also dries fast and leaves no residue, making it ideal for both spot cleaning and routine PCB maintenance.
Using the Wrong Type of Wipe or Swab
Paper towels or cotton swabs can leave lint or fibers that interfere with circuits. They can also absorb solvent too quickly, making them inefficient for proper cleaning. Techspray Wipes and Foam Swabs are engineered for electronics — they’re lint-free, highly absorbent, and compatible with cleaning solvents.
Cleaning the Entire Board When Only Spot Cleaning Is Needed
Not every cleaning job requires cleaning the whole PCB. In many cases, only specific areas have flux residue or needs repairing. Over-cleaning can expose sensitive components to unnecessary solvent and increase the risk of damage. The Techspray Flux Remover Pen and Conformal Coating Remover Pen allow for spot treatment of flux residue or coating removal without wasting product or affecting unaffected areas.
Ignoring Safety and ESD Precautions
Working with cleaning chemicals requires proper safety measures. Always wear gloves, goggles, and ensure good ventilation when using solvents. Techspray products are designed with safety in mind, and when used with ESD-safe tools like anti-static brushes and mats, they help protect both the user and the delicate electronic components.
