How to Clean PCB

I know one guy who cleans old radios in a dishwasher machine. I prefer a combination of alcohol (flux remover), brush and pressurized air. I developed this method while cleaning RC nitro helicopters and I am very pleased with how it works on PCBs.


InJet® 888 CRD

We introduce you innovative cleaning machine InJet® 888 CRD. This cleaning machine is suitable for cleaning of PCBs after soldering, reflow oven parts and soldering frames. InJet® 888 CRD is fully automated 1-chamber cleaning machine with processes of cleaning, rinsing and drying. It has three 4-arm rotations which allow to use the machine with double baskets. Thanks to easy removable middle arm it can be used only with one bottom basket to clean large parts. InJet® 888 CRD can be upgraded by additional external set for double rinsing process (CRRD). Fully designed and engineered by DCT Czech.

Proper ultrasonic cleaning solution for electronics PART 1

If you’re putting any type of alcohol in your ultrasonic cleaner, you need to stop (unless you like wasting money and risking a fire). If you’re putting tap water in it to clean electronics, you need to stop. If you’re a professional wet electronics restoration business and you use a jewelry cleaning unit with jewelry cleaner, stop it right now.

I have suggested jewelry cleaners and cleaning solutions in the past for people on a budget and wanting to clean their own phone because once a DIYer, always a DIYer, and $600+ for a one-time cleaning of their own device isn’t very budget friendly. That said, if you really want your baby and vacation photos from your wet phone, hire someone with some experience and proper tools. 😉

PCB Cleaning demo.MPG

Consists of “Valgro-Fynex” Material compressed on to a core for use on printed circuit cleaning and scrubbing machine and are ideals for all cleaning operations. The PCB used in the electronics industries are getting smaller and lighter with demand for higher performance, greater reliability, higher density, finer patterns and multi-layer constructions have changed the methods and material used to make PCB. It demands proper surface conditioning for every step of the manufacturing process.


Ultrasonic PCB cleaning

The primary function of cleaning printed circuit boards and assemblies, removal of flux residues, which in the operation of electronic equipment can have a negative impact on its reliability. Often, after ascertaining the causes of failures of electronic devices, we understand that after the deposition of components and melting the solder another important procedure has to be done – clearing circuit boards.
