█ 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

Resistors sticking to tape -- We have been experiencing a strange issue with a few reels where resistors are occasionally sticking to the tape when it is peeled back on the feeder. Has anyone seen this before? If we try to move the stuck pats with a tweezers they move easily so it doesn't seem to be an adhesive issue. Static is an obvious concern but of course the machine is well grounded and humidity levels are slightly higher here now in summer so this is counter intuitive.

GSM Genesis waiting for PowerPC Server -- One of our GSM genesis machines has been getting hung up on an error message "Waiting for notification from PowerPC that Servers are started." This only happens on the first boot; powering it down for several minutes then powering back up resolves the issue. I am not sure where to look for a source on this, has anyone seen this before? Thanks in advance.
