Jak perfektně vyčistit DPS po zapájení

Whatˇs is the Customer´s story?

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.

WHAT WE TESTED?

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

PCBA BEFORE Cleaning / AFTER Cleaning

Due to our own R&D team we are continuosly developing new cleaning solutions for our customers, customized according to their needs.

DCT has also its own production, where all cleaning systems are manufactured.

RECOMMENDED CLEANING PROCESS

Cleaning:

Decotron® CP 381 / 15 min / 50°C

Rinsing:

DI Water / 7 min / 40°C / 1 μS

Drying:

hot air / 10 min / 80°C

15 minutes is a time, which was needed to completely clean flux residues from PCBs after the soldering process.

Flux residues were removed from most components in only 5 minutes, but one chip component with a small gap between solder joints and solder mask needed another 10 minutes to get 100% clean.

IONIC CONTAMINATION TEST

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.

RESULTS OF TESTING

Success rate: 100%

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.
