The customer has been using DCT cleaning solution (InJet® 388 with cleaning fluid Decotron® 355S) to clean PCBAs from flux residues. Hovewer, DCT was asked to verify the suitability of the cleaning process and evetually to recommend other, more inovative solution for them, as DCT is still developing new cleaning agents and clening systems to provide the best cleaning solution on the market.
We removed flux residues from PCBs after soldering with another and newer DCT cleaning agent (Decotron® CP 381), designed for this process.
Type of of Solder Paste: ALPHA CVP-390
Type of Sample: Pallet of PCBAs: 15,3 x 11,5 cm
Cleanliness is checked in our Technical data sheet ROSE tester.
It is a device designed to measure the amount of ionizable impurities of a PCB.
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 set to 0,156 μg NaCl/cm2.
The result of measured ionic contamination (blue line) of cleaned PCB is 0,08 μg NaCl/cm2.
Other recommended
cleaning systems
Decotron® CP 381 was evaluated as the best cleaning agent for removal of flux residues from PCBAs, based on a cleaning test and ionic contamination test, which we have done for the customer at DCT DEMO center. We are always customer-oriented and we are always willing to verify the suitability of currently used cleaning solutions. We are more than happy to recommend better and newer cleaning solution as it was in this particular case study.
