SMTnet Express: Here's What Happened On SMTnet This Week -- November 20, 2025

█ 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.

What range can it operate? -- What voltage range can the AD5245BRJZ5-RL7 operate on, and why is it important? Details:https://www.cff-chips.com/productdetail/ad5245brjz5-rl7

Yamaha YG100/Assembleon Opal XII camera brightness -- We operate a pair of Yamaha YG series pick and place machines (I believe also known as Assembleon Opal XII). One of them has nice, bright images from the cameras, while on the other the images are very dull. It's starting to cause problems with recognition on small parts like 0402 (imperial). We notice poor brightness from both the front and rear line scan cameras used to vision components, so it can't be the camera itself. The camera lighting LEDs are controlled by specific separate boards, so it can't be an issue there or we would see a different result front and back. Our second machine has the same cameras and we see a much brighter camera image and no visioning issues. Does anybody have any suggestions of where else we should be looking?
