█ Electronics Manufacturing Technical Articles

Over the past several years, post-reflow defluxing of circuit assemblies has gained in popularity. Microminiaturization of components and boards, combined with higher expected reliability and increased product liability, have contributed to the prominence of defluxing. Lead-free solder paste - with its higher reflow temperatures and negative effects on flux - increase ...

Identifying Flux Residues

Why identify flux residues? The primary purpose of flux is to reduce species of metal oxides from solderable surfaces, and to act as a mechanism for lifting and removing debris. If the assembly is not properly cleaned after manufacturing, flux may continue to reduce metals and may eventually corrode the assembly. When the assembly is powered, the metal ions may...

Non-Destructive Test Methods

Failure analysis (FA), by its very nature, is needed only when things goawry. Before any testing is performed on the sample, a decision mustbe made as to whether or not the sample is allowed to be destroyedin the process of testing. Non-destructive testing can allow for re-use of the assembly since the functionality is not altered, but there still remains the possibility ...

Process Control of Ionic Contamination Achieving 6-Sigma Criteria in The Assembly of Electronic Circuits

Ionic contamination testing as a process control tool a newly developed testing protocol based on IPC-TM 650 2.3.25, was established to enable monitoring of ionic contamination within series production. The testing procedure was successfully implemented within the production of high reliability, safety critical electronic circuits, involving multiple ...

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.

█ Printed Circuit Board Assembly & PCB Design Forum

Need Help with BGA Soldering in PoP Assembly -- Dear colleagues, Good day to all. We are facing an issue with soldering the lower BGA component in a Package-on-Package (PoP) assembly. To address this, we drilled a hole and installed a thermocouple. Using a KIC device, we created a thermal profile corresponding to the solder paste (KOKI S3X58-M500). However, X-ray inspection shows insufficient soldering in the lower BGA. Attempts to slightly decrease the conveyor speed and increase the temperature have brought only minimal improvements. We are working with a Heller 1809 MK5 10-zone reflow oven. We would appreciate any suggestions or advice on how to resolve this issue.

Cyberoptics axis names? Machine fails to home. -- I just got a used SE500 Ultra and the machine appears to move in the X and Y, conveyor belts and width. It however fails to home. I assume the end sensor has physically moved or it's an issue with the Z axis. The logging says it's axis 0, however the docs don't say which axis is zero. Is it X? Is there anywhere that shows IO values? If so I could find out which sensor isn't currently on when it tries to home. It doesn't have a way to view them that I can find like the QX500 does.
