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

Is Cleaning Really Worth the HASL? - Part 1
This study brings up the importance of belt speed, pressure, water
quality, wash and rinse temperature, equipment maintenance &
material choices in maintaining good cleaning.

Is Cleaning Really Worth the HASL? - Part 2
This study examines how HASL flux residues on bare boards follow
through till final assembly. It is important to query end
customer on ionic cleanliness levels necessary.

Incoming Component Cleanliness
Components can often cause failures if dirty, even if the assembly
process is no-clean. This article discusses how tap water
cleaning is not enough to achieve ionic cleanliness.

White Residues - Good or Bad?
White residues are not always bad, but are often indicative of an
ineffective cleaning protocol. Saponifiers need to be
qualified and water quality achieved for good cleaning results.
