| Has any anyone established / published quality standards for BGA solder joints? Is IPC-A-610 in process of adding standards for BGAs? | The debate continues. I have felt for some time a maximum 20% voiding is allowable under certain conditions (w

We are a small company of 110 people and I am the only manufacturing engineer. We have "work cells", but they are not time balanced like a true work cell would be; they are a group of primarily benches arranged to build a particular product(s). More

Dean, My first thought relates to your statement: "I was under the impression that manufacturing engineering was responsible..." We find any statement that begins similar to this to be indicative of other issues within an organization. Unless it'

Mario, Hi, basic point about all quality systems, is the cost justified? Traceability is just one aspect coverage in the quality system. As a pointer, is your diploma project research might focus and narrow down into tracability in high-end product

Without being clear on whether you're talking about: * Standard air knives at the back-end of your in-line cleaner ... OR * Hand held or similar nozzle. Standard air knives: This causes no problem with ESD because the relative humidity is so high t

Ted Dangelmayer's book [ESD Program Management: A Realistic Approach to Continuous Measurable Improvement in Static Control; Dangelmayer, T; Kluwer Academic Pub 1999 e2; 0412136716] is excellent. Often, ESD supplies sales-types use the "Chicken Littl

First, we're not real concerned about gluing induced ESD damage, but conformal coating has a tremendous potential to damage sensitive components. We found a charge of 12 kV generated during the aerosol spraying. Second, ESD-stuff IS very confusing.

Thanks for the responses, and I tend to agree. I would much rather go through a more structured continuous improvment process (set goals, meet them, set new goals and so on). Our company is rather small and made the jump from all through hole to mi

The most effective method is to monitor both printing results and parameters. Periodically (maybe once per month), run QCCalc or another program to measure the machine's capability to hold its set parameters. I also run control charts on the paste h
