The customer used flammable and aggressive fluid to remove solder paste ALPHA OM-340 88-3-M1 from stencils, misprints, and PCBAs. This type of fluid was unfortunately also highly foaming. The customer’s need has been lower VOC, which would be consistent with the set limit, so in this case, we solved ecological problems, but also economical savings.
Our R&D Team Tested Cleaning of:
Type of Solder Paste: ALPHA OM-340 88-3-M1
Types of Cleaned Components: 2 panels of soldered PCBAs, 1 panel of PCBs without components
A) Printing stencils from unsoldered ALPHA OM-340 88-3-M1 solder paste
B) Misprints of ALPHA OM-340 88-3-M1 solder paste on PCBs
C) PCBAs after soldering process with ALPHA OM-340 88-3-M1 solder paste
To make mounting of PCBs precise, printing stencils have to be clean! This is the reason why any production should clean printing stencils regularly.
We have performed ROSE (resistivity of solvent extract) test after cleaning with Decotron® CP381 cleaning agent in Injet® 388 CRD cleaning system.
IPC limit of ionic contamination (red line) corresponds to 1,56 μg NaCl/cm2.
Limit of ionic contamination (green line) is an option to enter your own limit – in this case the limit was not specified by the customer.
Result of measured ionic contamination (blue line) is 0,198 μg NaCl/cm2
Decotron® CP381 for all three applications with set parameters described in this case study.

cleaning systems
The customer was satisfied with the results as we provided them with a more eco-friendly and sophisticated cleaning agent, which will lower their VOC, and which is also more economical speaking in the long term view.
