The last time I got glasses, I let the salesman talk me into the UV/Anti-Glare coating, which I’d never had before. After time, the coating began to develop tiny, really fine scratches, which kept building and building. They got so bad, I was going to get new glasses — until a friend recommended Armour Etch, a glass etching cream you can get at art/craft stores like Michael’s or Dick Blick. The way it removed the coating, leaving me with a perfectly unscratched lens, was phenomenal!! I do experience a little more glare without the coating, but I can live with that — having the scratches was driving me nuts! Instead of having to spend $100+ on new lenses, I got away with spending a little over $10!

I was recently looking through some of my old game miniatures and terrain and found some pieces of “scatter terrain” that I’d made for the awesome post-apocalyptic car combat game Gaslands (think: Mad Max). These are probably some of the best pieces I’ve ever modeled and painted and I have no memory of the colors, techniques, and tricks I used (it was many years ago). I now kick myself for not taking notes. A decade ago, I was really good about keeping a Cahiers notebook with notes from my projects, what parts and techniques I’d employed. Because of that, I can still recreate those projects today. Seeing these successful terrain pieces has caused me to re-dedicate myself to keeping project notes and recipes, paint colors used, key learnings, etc. moving forward. Above is a notebook I made years ago for keeping shop notes in my garage. It hangs from a pegboard there.

The ultimate goal for PCB inspection is ensuring and optimizing product performance and lifetime. Manufacturers and suppliers need fast and reliable inspection for screening defects and checking specifications to achieve cost-effective production.

Finding defects on PCBs and checking specifications quickly requires microscope solutions which help users overcome these challenges.

Whether a manufacturer or supplier, efficient and reliable PCB (printed-circuit board) inspection for quality control (QC), rework, failure analysis, and research and development (R&D) is crucial for achieving cost-effective production and competitive electronic products. The performance of PCBs is critically influenced by soldering, through holes, diodes, IC chips, and other components. All of these must be checked. To show compliance with the defined specifications, an imaging solution which enables reliable and accurate documentation is often required. Inspection microscopes assist manufacturers and suppliers with their QC, failure analysis, and R&D needs.

When a 3D perspective is important, as for handling and doing rework of PCBs, then a stereo microscope is required. Frequent microscope adjustments, e.g., refocusing and changing of zoom factor to enhance resolution and depth of field, can slow down inspection. These adjustments can be minimized with the FusionOptics technology. When looking through the eyepieces, you can perceive a PCB in 3D with both high resolution and large depth of field.

Electroplating is an electrochemical process used for depositing protective metallic layers, e.g., copper or tin, onto PCB interconnects or components. Defects and contamination which occur during electroplating can lead to poor electroplating quality or even PCB failure. Rapid and reliable visual inspection of electroplated components for defects can be done with optical microscopes. If a root cause analysis of defects or contamination is required, then a combination of optical microscopy and laser-induced breakdown spectroscopy (LIBS) for simultaneous visual and chemical analysis is recommended.

The cleanliness of PCBs is important, because small conductive particles can significantly increase the risk of failure. If these particles become present on PCBs during manufacturing, they can easily bridge small gaps between contacts and leads, causing a short circuit.

I love industrial training films from the mid-20th century. This one, from 1942, would have been soon after America had entered WWII, many men and women were entering the industrial workforce, and in need of training like this. Takeaway tips:Use the right file for the job. Files come in single or double cuts and various coarseness levels. Single-cut files are for smooth finishes, while double-cut files remove more excess material. Use coarse files for soft metals, fine for hard. Apply pressure only on the forward stroke to get a clean cut and prevent scratches. Use a consistent, long stroke to maintain control and accuracy. Metal chips can stick to the teeth, causing "pins" that scratch the surface. Tap your file on wood, or use a file card, to keep the surface clear for precision filing.

PCBs (printed circuit boards) are used in many electronic devices. A PCB serves as a support onto which electronic components are mounted to form a complete circuitry. Once the components are installed and a PCBA (printed circuit board assembly) is finished, then it can be installed in electronic devices to perform specific tasks like data processing.

Challenges encountered during PCB inspection with an imaging system may lead to inefficiency, reduced throughput, and higher defect-ppm rates. For example, when users are unable to:

Thus, there is a need for rapid and reliable cleanliness analysis of PCBs to minimize or eliminate contamination and ensure PCB performance. The analysis involves accurate determination of particle dimensions and material following standards and guidelines like ZVEI. Cleanliness analysis can be done using an optical microscope alone or in combination with laser-induced breakdown spectroscopy (LIBS). Chemical analysis with LIBS helps to determine accurately the potential of a particle to cause short circuits and efficiently find the contamination source.

A PCB (printed circuit board) is used to assemble electronic components into a complete circuitry. They are used in electronic devices like computers, tablets, smart phones, or measurement instrumentation. PCBs are made of alternating layers of insulating and conducting materials and have holes or other ways for mounting and interconnection of electrical components onto the board. Different types of boards (single or multi-layer) and designs (blind, buried, or through-hole vias or surface mount) exist depending on the application.

Hi Gareth... Always enjoy your newsletter. I don’t do a lot of projects that involve hammering but I have a new hammer I’m excited to share. I know there are reasons for long handles, but this hammer with a short handle is perfect for my 72 year old hands. The soft grippy handle is easy to hold. I have not tried the magnetic nail starter — it wasn’t a feature I was particularly interested in, but who knows? I may love it. Less than $10 on Amazon.

A PCB is a printed circuit board, a bare support without electronic components simply used to assemble together components into a complete circuit. A PCBA is a printed circuit board assembly, the finished product with all the electronic components attached to the PCB and ready to be used in an electronic device.

In this Stumpy Nubs video, James looks at tools that have become indispensable in his woodshop. While this video is directed at woodworkers, covering things like the Milescraft router Omnibase and the Accu-Burr Burnisher and Scraper, other tools, like painting pyramids and the Airshield Pro Respirator and Face Shield can apply to other domains of makery.

A practical magnification range for PCB (printed-circuit board) inspection with a stereo or digital microscope is 5x to 30x (including objective, zoom, and eyepieces). This range enables both a large overview of a PCB area at lower magnification (around 5x) and visualization of fine details at higher magnifications (around 25-30x).

Recently, while putting together a Swytch bike kit for my wife’s Cannondale, I stripped an M4 bolt on the kit’s battery mount. The bolt head was already below the surface so I couldn’t use my Dremel to turn it into a slotted head to back it out (a trick I have used too many times). I bumped into this product in a video and decided to give it a try. You simply apply a dollop to the head and back the bolt/screw out. I’ll be darned if it didn’t work. The main use of the product is to prevent cam-out in the first place. What is this sorcery? It’s a polyvinyl alcohol with a gritty mineral filler. As a result, it creates additional friction between the fastener head and the driver head. It basically gives you increased traction for driving in or backing out fasteners. And, as in my case, it can work to remove moderately stripped heads. Worth tossing into your toolbox.

Stereo and digital microscopes are ideal for PCB (printed-circuit board) inspection. When looking for defects or doing rework: these microscopes enable easy handling of PCSs under the objective lens, straightforward use of different types of illumination to better reveal details, and the ability to go quickly from an overview to zooming in on areas of interest. A stereo microscope with FusionOptics allows a 3D perception of the PCB while having both higher resolution and larger depth of field.

A word of caution: this acid (hydrofluoric) solution is for glass etching, so you CANNOT use Armour Etch on glass lenses; otherwise, you will literally etch and ruin your lenses. You must be certain you have plastic lenses. It should be safe on most polycarbonate lenses (it left mine completely unscathed). However, I’d only try this when you have nothing to lose. Always do a small test first, too. After applying the cream to a tiny spot, I went ahead and did the whole lens, coating each side for 1-2 minutes, rinsing, and then repeating. While I wore standard latex gloves and did this in a well-vented area, Armour Etch is designed for crafters, so it doesn’t require a fume hood or anything. Afterward, I rinsed the glasses for a few minutes under hot tap water, applied soap and water, and finally used a lens cloth. I was taking a big risk since I’d never done glass etching before and I wasn’t certain it would work. But it did, and I got a “like new” pair of glasses for just a few bucks!

To observe the internal structure of PCBs, with the goal of identifying defects, cross sectioning is required as the materials are normally opaque. Cross-section analysis is a useful technique for QC of PCBs. It is also exploited for failure analysis and R&D. The analysis is done by cutting through a PCB and then grinding and polishing the cross section to obtain a smooth surface. Analysis of the cross section can be performed with high-resolution optical or electron microscopy and spectroscopy. The aim is to reveal the internal structure and composition of PCB layers and its components, confirm the presence or absence of coatings, vias, etc.

I got a huge bump in subscribers after a recent Retro Recomendo newsletter mentioned me. Twice. One piece was about Gar’s Tips & Tools itself (“Each issue has several handy tidbits about interesting tools, novel ways to use tools, and how to maintain your workshop”). The other was something I wrote for Cool Tools many years ago about these house paint touch-up bottles. “After you finish painting a room, pour a little of the left-over paint into one of these small touch up bottles. The plastic bottles contain a small applicator brush inside (plus a marble to shake/stir the paint) which makes it super easy to break it out to touch up as things happen.”

When electronic components are assembled and attached, usually by soldering, onto a PCB (printed circuit board), then it becomes a PCBA (printed circuit board assembly). It is a PCBA which is actually inserted into an electronic device like a computer, tablet, smart phone, or measurement instrument.

PCB (printed-circuit board) inspection is crucial for quality control, ensuring optimal performance of electronic components, and cost-effective, reliable PCB production. It is performed by doing visual inspection of boards to identify potentially damaging defects in terms of soldering, leads, component contacts, presence of particles and other contamination, during manufacturing and production.
