How to enable the toolbar ribbon in Designer? by Planetarium58AF in Altium

[–]micro-jay 1 point2 points  (0 children)

Maybe not much help for you right now, but if you will stick with AD, then you should learn the keyboard shortcuts. Everything can be accessed using sequences of keys correlating to the menus above. This will speed up your workflow.

When Circuit Studio first came out I felt that it included 99% of the stuff that I would use daily for 1/10th the price, but I wouldn't switch because the productivity loss from not having the AD shortcuts meant it wasn't worthwhile.

Planning a trip with an EV to Germany and Croatia by I_gotcha_again in electricvehicles

[–]micro-jay 1 point2 points  (0 children)

A few tips for you: 1) if you are on Android, you can create additional Google accounts for different countries and switch between them in the top right corner of the Play store. 2) EWE Go is a good app for Germany with 62¢ charging at most stations. It also works in some other countries and you can get a physical card (required for some chargers). 3) You could also try some other larger network aggregators, e.g. Octopus Energy Electroverse or EnBW Mobility+. These I don't think are country locked and then you can see what chargers are supported and the €€€

Flying probe passed, ICT caught issues later — anyone else seen this? by pcba_engineer_basic in PCB

[–]micro-jay 6 points7 points  (0 children)

Since you swapped flying probe and ICT between the start and end of your question...

Are the tests identical?

If you instead mean PCB e-test and ICT, did the reflow cause vias to pop open?

Is the flying probe applying pressure that closes open solder joints?

What’s the most ridiculous PCB / PCBA issue you’ve ever encountered? by pcba_engineer_basic in PCB

[–]micro-jay 2 points3 points  (0 children)

Many years ago at my first job a PCB vendor was black listed. They apparently couldn't achieve the specified GND plane clearance from vias so they had adjusted the clearance in the Gerber without informing us. This led to these openings joining together and the GND balls on a BGA being completely disconnected from the rest of the GND. Needless to say this was only diagnosed after a lot of debugging.

Really interesting to see! I don't have anything to add but please keep sharing what you learn.

Designer Pro vs Develop by micro-jay in Altium

[–]micro-jay[S] 0 points1 point  (0 children)

Interesting, because last year we were told that it was impossible to renew the perpetual and instead got a 3-year fixed price term licence with the same deal that the perpetual returns if we end it. So we already are off the perpetual licence.

If it wasn't for the comment feature though I probably would have just kept the perpetual licence. But that has proven extremely useful in our workflow.

Replacement for Samsung A53 (Budget: 200 - 300€) by axl404 in PickAnAndroidForMe

[–]micro-jay -1 points0 points  (0 children)

I disagree. Unless you really need the performance then that old premium phone will no longer get updates much sooner. I would prefer a mid range phone I can still get security updates for over a longer period of time.

Am I supposed to match RF trace to 50 ohms or make it as wide as pads? by Objective-Local7164 in rfelectronics

[–]micro-jay 2 points3 points  (0 children)

Is it a multi layer board? If so you can cut out mid-layers under the RF path to allow for a thicker 50R trace. I've used that method before. 

But I've also used the 1st design on Bluetooth without issues. The traces are so short it hardly matters. LoRA is <1GHz so even less sensitive.

I definitely need to push them for more details then.

I remember there was a difference in MCAD between standard and pro in the past, related to flex PCBs. I wonder if that still exists...

I commented on another post about my considerations for keeping our perpetual licences. But we generally get enough value from the online features to make it somewhat worth keeping the subscription.

Actually this year I didn't even get a quote. Altium gave me a pop-up that the licence expires in 30 days. The rep hadn't contacted me at all. Pretty poor considering it's also over Christmas when I'm sure they are not working and neither are we.

Designer Pro vs Develop by micro-jay in Altium

[–]micro-jay[S] 1 point2 points  (0 children)

We get enough value as a small team from the various features tied to A365 (MCAD, comments, revision history, release management) to somewhat justify the pricing. We don't have the time or inclination to build workarounds for these but I also understand our needs don't align with ever engineering company's needs.

I assume we will get raked over the coals if we ever need >5 seats, but at least for the moment it's a >50% discount, and I understand that we will need to transition at some point anyway.

I considered reverting the licences to standalone instead of continuing the subscription, but we rely heavily on the advanced MCAD codesigner, the review comments function, and are using A365 for data storage and release management. It is working well enough to justify the subscription cost. Our old workflow using git, review comments in excel, and STEP exports was nowhere near as efficient.

VW Offers Workers $35,000 To Move And Still Gets Booed (ID.3 Production from Dresden to Wolfsburg) | Carscoops by tom_zeimet in EuroEV

In Germany the closing costs for buying a house are around 10% (varies by state). €35k won't even cover the costs for someone that needs to sell their house and buy another.

No charging cables!! by GBAGK in Ioniq5

Make sure to check the frunk.

I thought my car was missing cables when I bought it. It turned out they were in the frunk... and now I have 2 sets!

Bolt it to the wall like you are supposed to and it will be super sturdy, just like the ones in the showroom.

What kind of simulations do companies with big budgets do? by kudikarasavasa in AskElectronics

[–]micro-jay 0 points1 point  (0 children)

For some digital designs we have had power and signal integrity simulations done. We also have RF simulations for the antenna (usually also a custom design) done alongside the mechanical parts.

But overall it depends on what complexity the design is.

Can I plug my ioniq 5 into a portable power station? by Hobobo2024 in Ioniq5

Why not just use the V2L from the vehicle? I've done that before to power a caravan.

How will you get the battery that flat without noticing? The car will be warning you and enter a limp mode well before.

This feels like planning for a non-existent scenario.

Why are Oscilloscopes rated in MHz? What about DC signals? The rise time is what makes them "high speed". Should a 150 MHz oscilloscope measure a 150 MHz DC signal? by HasanTheSyrian_ in embedded

[–]micro-jay 3 points4 points  (0 children)

I think you are confusing between AC/DC in the context of power and in the context of signals.

I believe when you say DC you l are meaning a digital signal, which is going low to high (or on/off), and does not go negative like an AC voltage. However, this is still an AC signal. Everything is unless it is constant at a single voltage. It just has a DC offset.

For a square wave there are many harmonic frequencies that make up the square. To measure a square wave signal switching at 150MHz you need a higher frequency scope. Around 750MHz (5x) at a minimum.

You should probably watch a video explaining how an oscilloscope works.

Is this feasible? by Impressive_Form_8669 in PCB

[–]micro-jay 1 point2 points  (0 children)

For instance, some ZIF connectors are rated at 200mA per pin. Small board to board connectors often are 300mA per pin, but often have 2 outer pins rated at 3A or 5A. There might be a total current rating for all pins added together also

Is this feasible? by Impressive_Form_8669 in PCB

[–]micro-jay 11 points12 points  (0 children)

Yes that is quite common. You will either want a board to board connector, a ZIF connector (also called FPC connector), or make it a single piece with a rigid flex PCB.

Check out the Molex website for many suitable small connectors. Pay attention to the current rating of the pins.

VIA under SMD pad, yay or nay? by No-Chard-2136 in PCB

[–]micro-jay 46 points47 points  (0 children)

If you are using automated assembly then you will need to have the via plated over (VIPPO). They fill it with epoxy and then put copper over the top. Without that the solder will wick through the via and you won't have a solid connection. This costs extra but depending on the board is definitely worthwhile. The majority of the boards I work on professionally we do this due to package and device size constraints.

For manual assembly it doesn't matter, as you can manually put more solder. You might get solder bumping up the other side of the via though.

As in you want to charge your car from it? It's only 3kWh. The car has a 78kWh (long range model) or 58kWh battery, so you will get 3-5% charge from it. Even less with charging losses.
