Coming soon - USB Plug with THM mounting tabs

We've had some requests to get our Trinkeys soldered up with USB C plugs instead of USB A and like, that turns out to not be trivial! we have to find a USB C plug with through hold tabs so they're nice and strong, and ideally one that isn't "Straddle Mount" where you have to manually place it on the two edges of a PCB. this connector is a nice balance, it has 12 pins so it isn't USB 3.0 but that's OK because right now we're only using USB 2 on our microcontrollers. there's only one CC pin, that's how the upstream can determine orientation. these are more expensive than USB type A but if this works, we can try making some Trinkeys that plug right into modern laptops.

EMC Design Pit Avoidance Guide：

Four no mnemonics

Why does your well-designed product fail EMC testing? The EMC team at Leiditech shares 4 practical EMC design techniques summarized in the “Four No” principles to help you avoid common pitfalls!

Principle 1: Make Current Take the Shortest Path, Not a Detour

Core Logic: High-frequency currents follow the “path of minimum inductance”. Larger loops → stronger radiation!

Key Insights from Leiditech Lab:

l Signal currents must form closed loops, with return paths closely following the outgoing paths.

l Low-frequency (kHz-level) currents follow the “path of minimum resistance”, with possibly dispersed return paths; high-frequency (MHz-level) currents follow the “path of minimum inductance”, with return paths closely adhering to the main trace.

l Design Tip: Place high-speed signals adjacent to their return planes and reduce the spacing between the signal layer and the ground plane.

Principle 2: Do Not Split the Signal Return Plane

Leiditech EMC engineers’ golden rule: Provide a complete return plane for all signal currents. For low-frequency signals prone to interference or likely to cause board-level interference, use dedicated trace layers to route return currents back to the source rather than splitting the plane. Arbitrary slotting/dividing the ground plane can cause abrupt changes in return paths → surging EMI!

Exceptions:

Independent return traces may be used only for isolating low-frequency sensitive signals (e.g., audio power supplies), provided:

l The independent layer has a separate return path and does not cross high-frequency planes.

l Consult Leiditech EMC experts to avoid case-by-case misapplication.

Warning: A complete plane is the optimal solution in 99% of scenarios!

Principle 3: Do Not Route High-Speed Circuits Between Connectors

This is one of the most common issues in PCB designs evaluated by Leiditech Lab. Many simple designs that could easily meet EMC requirements (with no extra cost or effort) end up requiring extensive shielding and filtering due to violating this rule.

Why connector placement matters: At frequencies below several hundred MHz, wavelengths can be meter-scale or longer. While the PCB itself acts as a low-efficiency “antenna” due to its small electrical size, cables or external devices connected to the PCB can become efficient radiators.

When signal currents flow on traces and return through a complete plane, the voltage difference between any two points on the plane is typically proportional to the in-plane current. When all connectors are aligned along one side of the PCB, voltage differences between them are negligible. However, if high-speed circuits are routed between connectors, potential differences of several millivolts or more may arise, driving currents into connected cables and causing excessive radiation emissions.

Principle 4: Do Not Blindly Pursue the Fastest Edge; Control Signal Transition Time

Fast edges (1ns) → harmonics up to 2GHz; slow edges (5ns) → harmonics <500MHz.

Leiditech EMC Team’s Golden Ratio: Transition time ≈ 20% of the bit period (e.g., for a 100MHz clock, control edge rates within 2ns).

Assembly Compatibility of Rigid-Flex PCBs: Challenges and Best Practices

Rigid-Flex PCBs offer mechanical flexibility and space savings, but they also introduce unique challenges during PCB assembly. Unlike standard rigid boards, Rigid-Flex designs often require customized handling, modified assembly procedures, and special fixtures to ensure reliability and manufacturing yield.

This article highlights the key assembly compatibility factors to consider when working with Rigid-Flex PCBs.

1. Handling and Support During SMT

Rigid-Flex PCBs are not flat and rigid throughout. The flexible areas lack structural support, which can cause issues during pick-and-place and reflow processes.

Challenges:

Flex areas may droop or shift during placement

Uneven board thickness requires customized carrier trays

Vibration or vacuum pickup may damage unsupported zones

Best practices:

Use dedicated fixtures or pallets to stabilize the board during SMT

Keep flex zones outside the reflow region if not in use

Avoid placing components too close to flex/rigid transition zones

Use bottom-side supports during reflow to prevent sagging

2. Reflow Soldering Considerations

Rigid-Flex boards often contain materials with different thermal behaviors (e.g., FR-4 and polyimide). This affects reflow performance.

Recommendations:

Use gradual heating profiles to reduce thermal stress between layers

Pre-bake boards before assembly to remove moisture from polyimide (typically 110–125°C for 4–8 hours)

Avoid excessive reflow cycles — confirm your stack-up supports the required thermal budget

3. Component Placement Guidelines

Due to dynamic stress and bending zones, component placement on Rigid-Flex boards requires special attention.

Do not place components or vias in active flex areas

Maintain a clearance buffer zone between components and flex/rigid interfaces (typically 1–2 mm minimum)

Place heavy or high-pin-count components in rigid zones only

Use stiffeners under connector areas to enhance mechanical strength

4. Wave Soldering and Mixed Assembly

If your design involves through-hole components, wave soldering may be used — but only in rigid zones.

Key points:

Flex sections must be protected from heat and physical drag

Consider selective wave soldering or manual soldering for hybrid assemblies

Mask flex areas to prevent contamination or overheating

5. Depaneling and Final Assembly

Rigid-Flex boards often feature irregular outlines, cutouts, and multiple folding lines, which require precise handling.

Use laser cutting or CNC routing for clean edges on both rigid and flex parts

Avoid mechanical shearing that could damage internal layers

During final integration, use controlled folding fixtures to prevent over-bending

If the product requires folding before enclosure assembly, define the correct fold sequence and bend radius in the assembly instructions.

6. Packaging and Transport

Flex zones are mechanically fragile and sensitive to pressure, which makes packaging especially important.

Guidelines:

Avoid stacking boards directly on each other

Use custom foam inserts or anti-static trays with support under rigid areas

Ensure bend zones are kept flat and uncompressed during shipping

7. Documentation and Communication

To ensure smooth assembly, detailed documentation is essential:

Provide 3D drawings showing folding direction and radius

Define "no-go" areas for component placement and tooling holes

Share stack-up data and material specs with the assembler

Clearly label flex areas and handling restrictions on silkscreen or fab drawings

Final Thoughts

Rigid-Flex PCB assembly requires more than standard SMT techniques. From reflow and handling to packaging and integration, each step must accommodate the unique structure and material mix of the board.

By planning ahead, using proper fixtures, and coordinating closely with the assembly house, you can ensure smooth production and maximize the reliability of your Rigid-Flex products.

Learning blender to improve the case on my own.

With rapid prototyping now sorted out, I've started learning blender myself to try and make edits to the case easily. It's been slow progress so far, with my friend George coaching me on different things to expand my currently limited blender experience. I've decided to keep the top of the case the same, as it needs no editing and the design is both functional and looks good visually.

This means I needed to edit the bottom of the case, and by using the extrude tool, along with learning how to dissolve faces and add cubes, I evolved the case over 5 designs, with iterative testing with a half made slimevr to test fit everything.

Here is a picture of all of my prototypes I did myself, i'll explain how I went iterating them over time.

Version 1 The first thing i noticed was how in prototype 2, my batteries were being pierced by the sharp edges formed after trimming down the solder joints, and how the battery had no proper place to sit, so that's the first thing I tried to Improve. By adding a small barrier around the inside of the case to let the battery drop down into it. I printed this version and the bottom of the case pierced from being too thin.

Version 2

All I did in this version was make the bottom of the case thicker, which fixed the issue of it piercing. Although the large sharp corners dug into my skin when tested with a strap over the case.

Version 3

I changed the bottom of the case to use a smaller platform to thicken the bottom of the case, I also added a small cutout to the side of the barrier, to allow for the cables of the battery to go out to the top, as I planned to switch to 2 pin JST connectors for the battery, and they could not fit in the bottom of the case due to there not being enough space.

Version 4 I made the cutout bigger and lower down, as in my testing there was not ample enough space for the cable of the battery to fit through. I also removed 2 out of the 3 standoffs, as they kept snapping off in my testing and fitting the PCBs inside of the cases. I still needed one to keep the PCB stable and in-place.

Version 5 I added small standoffs to every corner, to make sure the PCB would not pierce the battery anymore while maintaining space to easily fit into the hole. This design has worked well since I made it, and I plan to make all of the trackers with this design as I believe it will be durable and long-lasting.
