Services: Cleaning Electronics & Components

Foresite has the capability to clean both bare boards and finished assemblies.  Using a variety of methods, Foresite can assure that your boards are clean and prepared for reliable field performance.  Whether needs involve cleaning of the total board or only a specific localized area, we have the tools and knowledge to complete the task. 

Some of the specific areas we specialize in include:

 

We have the capabilities of steam cleaning in both batch and inline cleaners. Our protocol is qualified to IPC ANSI-J-Std 001 for water soluble flux cleaning and cleaning of no-clean flux residues.  The systems are designed for low-pressure, high flood saponified cleaning and are used in conjunction with isolated steam allowing us the flexibility to clean a variety of products and contaminants. Using our cleaning systems, we are able to handle a range of projects as small as one sample up to hundreds of thousands of assemblies.  Our techniques are proven not to degrade bradley labels, legending or marking inks. We can customize our cleaning process to adjust for parts that are water intolerant.  All IPC directed ESD protocols are followed for protection of your product.

 

Once cleaning is completed, results will be validated by certified IPC 610 visual inspection as well as ion chromatography analysis.  With each return shipment, a certificate of compliance will be provided.  If required, each cleaned board can be marked. 

 

If you have a cleaning need, please feel free to email ForesiteInfo@residues.com with your information and to obtain a quote.
