Cleanliness of Stencils and Cleaned Misprinted Circuit Boards

The effectiveness of cleaning stencils and misprinted/dirty printed circuit boards can be effectively monitored. This can be done by washing known clean circuit boards and then checking to see if they have stayed clean as a result of the washing process.

Cleaning Of Assembled PCBs - A Crucial Way of Enhancing Product Reliability and Avoiding Problems in the Field

Over the last years more and more international newspapers reported in Europe / USA and Japan: "Tunnel train got stuck under the Channel - thousands of people stranded", "Recall of thousands of cars to workshops for control and repair", "Power Failures left households without energy for hours." Very often news like this relate to malfunctions of electric and electronic circuits under ...

Stencil Printing Yield Improvements

Stencil printing capability is becoming more important as the range of component sizes assembled on a single board increases. Coupled with increased component density, solder paste sticking to the aperture sidewalls and bottom of the stencil can cause insufficient solder paste deposits and solder bridging. Yield improvement requires increased focus on stencil technology, printer capability ...

Stencil Cleaning Handbook

Back in the "good old days," stencil cleaning was effortless and effective. CFC-based solvents were sprayed or wiped onto a stencil with apertures hundreds of times larger than modern-day components. The stencil cleaning process was not considered a value-added procedure; instead it was the cleaning of a production tool. How times have changed. The late-1980s ushered in ...

█ Printed Circuit Board Assembly & PCB Design Forum

Increasingly more difficult to verify part markings. -- I am wondering if others are seeing the same issues, and how you are dealing with it. I have found more and more datasheets that no longer have the "Part Marking" indicated. I say no longer, because I have managed to find a few older revisions of the same datasheet that had it, and it has now been removed. I am told this is to help stop counterfeiting, which makes very little sense to me. Regardless, when I cannot verify the part is correct, based on the marking and datasheet, we have to contact the vendor. I just had one that was purchased as cut tape, and no way to verify the parts are correct. It took them 8 days to finally get back to me, and when they did, they sent a photo of the label on the reel that specifically lists the part marking. I don't have 8 days to hold up production for this.

Reflow Oven Cleaning Agents -- Which cleaning agent is best for cleaning the reflow oven, especially in the hotter zones? We have found that the cleaning agent "Promoclean Oven 4" from Inventec can be used for the entrance area and the first zone. We let it work for a few minutes and the dirty parts can be cleaned quite easily. However, the agent hardly works in the hotter zones. Do you have any good products or tips for cleaning the oven thoroughly? We currently only have one line with one oven. Therefore, an ultrasonic cleaner of this size is not worthwhile. Thanks for any advice! Best regards Manuel
