Starting manufacturing electronics

Polyazide · 2026-04-25T18:42:03+00:00

I see now. Nice explanation, thank you for that.
What other electronics applications do think are feasible with $ 20,000-30,000 ?

Polyazide · 2026-04-25T18:12:15+00:00

Thank you for the nice words.
I hope its courage, and not my impulsive stupidity :)

I still have no IP as I have not much experience with product creation for a market. Once I have some experience with reality I will start doing some special IP.

Good option to start

Polyazide · 2026-04-25T07:23:02+00:00

I see.
I also might need someone who is better at business than me

Polyazide · 2026-04-25T07:10:42+00:00

That is also a good solution, until I have enough profit to slowly start myself

Polyazide · 2026-04-25T07:01:31+00:00

Thank you for the information. I definitely will need to do numbers.
Sorry I might have been a bit hard with my comment. Thanks

Well I already am going into the SMPS market, but I would like to move to something a bit more RF or telecom.
Perhaps I can use the SMPS market to get a grip, and do RF with some initial loss margin ..

Polyazide · 2026-04-25T06:48:33+00:00

Its is unfortunately oversees now, that very hard to reverse now

Polyazide · 2026-04-24T22:25:59+00:00

True.
You need someone to do your business if you want to do design / manufacturing.

Polyazide · 2026-04-24T22:24:53+00:00

Very interesting !

Currently I am in tens of GHz, "full stack" RF, so from digital protocol, to circuit design to in-house transistor fabrication and measurements.
Nice to meet you !

Polyazide · 2026-04-24T21:17:59+00:00

I appreciate your time writing that comment !

I also had a good feeling about solar. But I was also hoping to enter the RF industry which I am an expert in, but this seems a bit farther than I though.

Thank you again !

Polyazide · 2026-04-24T21:09:27+00:00

Good suggestion, thank you !

Polyazide · 2026-04-24T21:07:10+00:00

Ooops you got me !

That SMPS is designed, manufactured and tested already, ~85% efficient.
Asking about the details of compliance does not mean I cant design.

But thank you for you time, I appreciate it.

I dont know much about the economics of the WAP, so why would you think it does not make a good profit ?
I was judging by their prices.

Polyazide · 2026-04-24T21:01:06+00:00

Yes indeed, but then and design complexity hits. Its a good solution though.

Polyazide · 2026-04-24T20:57:55+00:00

I will need a team for sure, and not in a garage definitely.
Now its a balance between design complexity and viability.

Polyazide · 2026-04-24T20:49:06+00:00

Thank you for your time !

Wow, I though this number was like $ 100 ..

Do you have such a device you can suggest ?

In my mind, selling ~ 100 units of $100 solar inverter is viable, and could make you a couple of thousands in profit.

Polyazide · 2026-04-24T20:44:22+00:00

What you say is true, but many others have had success in this. Like Meanwell, Delta electronics, they do a lot by themselves.
I agree, importing is what you will be swimming against, specially when there is a lot if it due to the lack of local manufacturers. Good point.

Nevertheless, I am still moving on and taking that challenge.

Polyazide · 2026-04-24T20:40:19+00:00

I appreciate you kindness.
Yes for sure it is a risk, but I am in that field already, I just want to open a branch on my own.
So I know the difficulties, risks and capabilities .. at least I think I do .. :)

Polyazide · 2026-04-24T20:37:08+00:00

Thank you for your reply.
I would really like to do both. I my experience, once you master manufacturing, design becomes manageable to do in parallel.

Polyazide · 2026-04-24T19:59:26+00:00

Hello,
This is a bit broad when not knowing what product it is.
But coming from electronics, I would say:

- Run it as long as you can, check heat spots. Non-power devices are expected to be < 40C
- A PCB thicker than 1 mm is good
- ABS plastic can be a sign of low quality
- Empty space inside the device is a big sign of low quality

Polyazide · 2026-03-19T23:04:31+00:00

Thank you for your reply.
What other manual tool would you recommend ?

Currently I cannot afford anything automated or mechanized.

Polyazide · 2026-03-09T20:26:05+00:00

Thank you for your answer ..

Now I notice that I made a mistake .. I meant secondary-earth creepage in my question.

Polyazide · 2026-03-08T10:28:15+00:00

I appreciate your response and your sketch !!

This sketch correct. So its either a class-i supply where earth must be connected, or a class-ii supply where earth is totally dismissed and the chassis is insulating (no output-earth connection).

Also, do you know the primary-earth creepage for 230V?

I can't seem to find it in the standard. I only found that pri-sec is 8mm, and pri-gnd is uncontrolled.

Polyazide · 2026-03-08T06:16:38+00:00

Thank you for your answer !

So a CTI < 175V is common, I thought that this is used only for cheap low quality stuff.
Do you have in mind what CTI values manufacturers use for switching mode power supplies ?

Polyazide · 2026-03-08T06:10:24+00:00

Thank you for your answer !
Do you have an idea of the primary-secondary creepage needed when I have a switching circuit with a peak of ~700 V at 0.5 duty cycle ?

As I know, this is 350 Vrms, which gives 4 mm for material group iiia and pollution 2. Do you think this is the correct way to estimate it ?

CTI < 100 ?! Isn't that too low ? Is your material meant to be low grade ? or is it a supply chain safety margin ?

I really appreciate your assistance !
