Advanced Cleaning: Relationship Between Conductivity, Surface Tension and pH

Q: I am doing a conductivity study using Alconox detergent. I am seeing that the pH and Surface Tension listed on the COA differs between lots. Do you think these variables affect conductivity enough to alter my results?

A: Here’s the short answer… Surface tension does not have any interactive relationship with conductivity; pH has a very small, essentially negligible interaction with conductivity; and concentration and temperature are much bigger causes of change in conductivity.

Residual Chlorine on Printed Circuit Boards

Q. We have found chlorine present on our printed circuit boards after ultrasonic cleaning and distilled water rinse.  As ultrasonic cleaning detergent, we’re using either Liquinox or Detergent 8, but are unsure which one was used on affected boards.  Could either be contributing to this issue?

A. It’s highly unlikely that either detergent, or your cleaning process, is the source of the chlorine residue.  The cleaning process you described, if using detergent at recommended dilution levels, should successfully remove flux and process residues.

Cleaning Clear Anodized Aluminum

Q. We are seeing white residue on clear anodized aluminum that we are cleaning with Detojet. Why is this happening and what can we do to prevent it?
A. There are a few reasons this may be happening. 

Possible Reason 1: The Detojet® Low Foaming Liquid Detergent concentration may be too low in the wash cycle and the concentration of calcium, magnesium and iron too high in the water used.  This would result…

Residue Detection: Swab Method

Q. Do you have a recommended swab detection method for residual detergent?

A. We most certainly do.  It is suggested to use a swabbing area of 5 cm X 5 cm. Where extreme low level acceptance criteria on a low recovery residue, i.e. some product residues, it can help to….

Detergent Color Variations

Q. The color of our Liquinox is slightly different by lot number. Why is this happening? Is there an issue, perhaps we have done something wrong with storage?  

A. Do not fear! These color variations are normal. There is a range of acceptable color differences in Liquinox detergent. Differences in the age and storage conditions of the raw materials and of the Liquinox detergent itself will account for differences in color
