█ Electronics Manufacturing Technical Articles

One of the most critical factors in preventing corrosion from occurring in electronics is maintaining the state of cleanliness. This is not an easy feat to achieve. Corrosion is defined as the deterioration of a material or its properties due to a reaction of that material with its chemical environment. [1] So, to prevent corrosion from occurring, either the material or ...

Latent short circuit failure in high-rel PCBs caused by lack of cleanliness of PCB processes and base materials

Latent short circuit failures have been observed during testing of Printed Circuit Boards (PCB) for power distribution of spacecraft of the European Space Agency. Root cause analysis indicates that foreign fibers may have contaminated the PCB laminate. These fibers can provide a pathway for electromigration if they bridge the clearance between nets of different potential ...

The Reasons for Cleaning

This book is a compilation of many articles I have published on the subjects of cleaning, reliability, and cleanliness testing. Throughout these articles, I promote a common mantra: Clean is better than dirty. Less contamination is better than more contamination. Some assemblies can tolerate more contamination; others, less.

Failure Analysis - Using Ion Chromatography And Ion Chromatography/Mass Spec (IC/MS)

Since the 1980s the electronics industry has utilized ion chromatography (IC) analysis to understand the relationship of ions, and some organics, to product reliability. From component and board fabrication to complete electronic assemblies and their end-use environment, IC analysis has been the de facto method for evaluating ionic cleanliness of electronic hardware.

Characterize and Understand Functional Performance Of Cleaning QFN Packages on PCB Assemblies

Material and Process Characterization studies can be used to quantify the harmful effects that might arise from solder flux and other process residues left on external surfaces after soldering. Residues present on an electronic assembly can cause unwanted electrochemical reactions leading to intermittent performance and total failure. Components with terminations that extend underneath ...

Impurity limits for Sn100c according to J-STD-001 -- Hi colleagues, I hope you can give me clarity on this issue, anyone who has the JSTD-001 in its revision H, for the SN100C alloy, what are the limits of impurities allowed? Thank you for your support!

Nitroflow 60 Nitrogen Generator Scroll Compressor -- We bought a used Parker Balston Nitroflow 60 which has an integral scroll compressor. We're not familiar with the machine so hoping someone here might be. I am trying to figure a few things out: 1. When the compressor turns off from reaching pressure, the scroll pump runs backwards for a few seconds. Is this normal? 2. The nitrogen membrane has a constant flow out of the o2 exhaust even if nitrogen is not being used and is at pressure. Is this normal? 3. The compressor cycles every minute due to the flow out of the membrane unit as noted above. How frequently should it cycle when the n2 is not being consumed? Thanks!
