Other Tests Performed
- Cross-Sectioning Analysis
- This method is used to analyze solder joint integrity of PWB's and determine the consistency of the joint. Wetting, cracking, voiding and any other anomalies that may be present within the joint area are analyzed within the scope of this technique.
- Visual Inspection
- Visual Inspection can be performed on circuit boards to ensure the soldering process and placement of components is correct.
- Tap and Deionized Water Analysis
- To determine ionic content of source water and deionized water used for printed wiring board (PWB) manufacturing. Test includes critical ions such as Chloride, Bromide, and Sulfate.
- Modified ROSE
- This is a spin-off of the ROSE test. This techniques looks at total extractable ionic content of PWB's by extraction via high temperature waterbath prior to analysis. Again, this is for purposes of process control. Results are reported in sodium-chloride equivalents per unit area.
- Mixed Chemical Analysis
- This is usually performed when a straightforward titration cannot be carried out or when the analysis procedure is complex and time consuming. Typically analysis is performed on either mixtures of acids or bases, however, analysis can be done on almost any material not containing complex organics or heavy metals.
