US Domestic IC Assembly - Enhanced Plastic - Old School? Working on a driver IC for space applications at high pin-pin voltage, I find no onshore options besides QFNs with too-fine lead pitch for the voltage. Given low market volumes a custom package development is not a great plan. I'm liking the older quad J-lead / gullwing for their compliant leads (board flex @ shock/vibe or launch, etc.). Only find these at overseas OSAT houses in my searching thus far. Do you like, or fear, hard body non-leaded packages in your application, qualification and launch environment? Could use some insights from the likely users of such a part or those who've gone down this road. Call it 250V pin-pin. Can I count on a general practice of conformal coating which would (in theory) raise the pin-pin potential (volts/distance) suitably (and are the basic PCB creepage specs, all there is to it?) or is New Space so much about cost, that this treatment might be skipped? Based on what you know about board construction, what't your "happy place" for max volts per mm or mil, continuous (VIN) and pulsed (SW)? I'm thinking a 50-mil pitch leaded package (can't see any QFNs at that pitch) might be the answer but would really like to stay onshore. And the whole bit about leaded vs unleaded, I've got mostly old ideas based on hermetic package back-end and strategic systems thermal & mechanical. Anybody know of any legit, space grade, onshore, old school leadframes, good MSL mold compound service providers? I know it's not asking much.

It's a match: Changing requirements in laser technology 🤝 Profiles XMS from item Production equipment can be repeatedly adapted to changing production conditions - without losing any of its stability. ✅ How versatile can or should a laser machine be? The mechanical engineering company LASERVORM GmbH says: "If it's up to us, we can't add enough variations to our basic LV Midi, LV MidiX and LV Mini machines. We have just demonstrated the versatility and flexibility of the LV Midi for ifw Jena. The new configurations developed for this extend the modular system of the LV Midi and are now available to all our customers. A key element of this new version is the flexible passive enclosure made of anodized aluminium, which we developed together with item. This addition to our standard coated steel housing offers improved laser safety for powerful laser sources and significantly expands the range of applications for the LV Midi. In addition, the new version also offers significantly more convenient maintenance access - which is particularly valuable for frequent conversions in a research context.” #itemBuildingKitSystem #LaserTechnology #engineering

There are several types of compressed spring: 1. ** conical spiral spring ** (Conical Compression Springs): The coil diameter of this spring gradually changes along the spring length direction, providing a non-linear-displacement characteristics. Its advantage is that it can provide different elasticity in different compression stages, and it is suitable for applications that require a stable load response or limited space. 2. ** barrel springs ** (Barrel Springs): Also known as columnar spring or rectangular section compressed spring, it has a relatively large cross section, provides high load bearing capacity and good stability. It is often used in heavy types for heavy types. In mechanical and car suspension systems. 3. ** Hourglass Springs: There is a small diameter design in the middle, which makes the spring show special load characteristics in a certain range, such as increasing or reduced elasticity in a specific itinerary. 4. ** Standard linear compression Springs: It is the most common type. It is formed by the most common type of spacing and the same diameter, and its elasticity is proportional to the compression volume. 5. ** Variation Spring Springs (Variable Pitch Springs): The spacing between the coils is different. The design can achieve a more complex force-displacement curve to adapt to the performance requirements under specific conditions. 6. ** Torque Spring (Volute Springs): Although it is usually not classified as a compressed spring in the traditional sense, they do have a similar role when they are compressed. The turbine spring is composed of a tightly wrapped coil. It can be stacked and compressed, and it often occupies small space after complete compression. It is often used in applications that require large load release or compact installation space. Each type of compressed spring has its unique design characteristics to meet specific functional requirements in different industrial fields and application scenarios.
In the intricate world of mechanical design, compression springs play a pivotal role. Our latest blog delves into the diverse type of compression springs, focusing on their unique designs, applications, and the specific advantages and limitations they bring to various industries. So, what are the different types of compression springs? https://lnkd.in/eG28b-t4 #springs #manufacturing #wearelesjofors #potentialunleashed #ukmfg

Daily PCB Fact (1) - Understanding the Difference Between PTH and NPTH 1. PTH (Plated Through Hole): During the PCB manufacturing process, these holes are electroplated or plated with a conductive material, typically copper, to ensure electrical connectivity. PTH allows current to flow from one layer of the PCB to another, facilitating electrical connections across different layers. Key Features: ① Conductivity: PTH holes are conductive, allowing electrical current to pass through. ② Durability: With the presence of the plating, PTH holes are more durable and suitable for multiple insertions and withdrawals. ③ Cost: Due to the additional plating process, the cost is slightly higher than NPTH. 2. NPTH (Non-Plated Through Hole) NPTH stands for "Non-Plated Through Holes." These holes are not plated during the manufacturing process, so they do not provide electrical connections between layers. NPTH holes are primarily used for non-electrical purposes, such as mechanical support for components or heat dissipation. Key Features: ① Non-Conductivity: NPTH holes are non-conductive and not used for electrical connections. ② Cost-Effective: Since the plating step is omitted, NPTH holes are less expensive. ③ Limited Application: Mainly used for mechanical support, not suitable for occasions requiring electrical connections. Conclusion The choice between PTH and NPTH largely depends on your application needs. If you need to establish electrical connections between different layers of the PCB, PTH is essential. If you only need mechanical support without the need for electrical connections, NPTH may be a more economical option. I hope this fact helps you better understand the basics of PCB design and manufacturing. Stay tuned for more interesting PCB knowledge in our series. *Any questions please email: [email protected] #NPTH #PTH #pcbhole #via

What is the thin film clamp? Thin film clamp are mainly used in the manufacture and assembly of flexible solar panels. They are significantly different from ordinary mid-end clamps in terms of structural design, function, application scenarios and material applicability. Thin film clamps are products specifically used to fix, align and press flexible solar panels to ensure that the film material can be accurately fitted and fixed to the substrate or other components during the manufacturing and assembly process. Advantages of Thin film clamp: –Fix and align: Ensure that the film material does not slide or shift during processing, maintaining precise position and alignment. –Pressing: Provide uniform pressure to ensure that the film material fits tightly on the substrate to avoid the generation of bubbles or gaps. –Protection: Protect the film material from mechanical stress or damage. #thinfilmclamp #Solarclamp #Solaraccessories More detail kindly check >>> https://lnkd.in/gNxKwuxE William Chen TEL/Whatsapp:0086-183-5926-0008 Website: https://lnkd.in/eKmSR8y www.TopBestSolar.com E-mail: [email protected] [email protected] SOLAR PARTS COMPONENTS FACTORY TOP BEST SOLAR RACKING MANUFACTURER
