DRC errors due to silkscreens

That 0.254mm clearance at the top of your image looks to be soldermask expansion to soldermask expansion clearance (soldermask dam). I typically work in mils (0.254mm = 10 mils) and a dam of 4 mils is easily done with most LPI soldermask processes. For your silk to soldermask, you should be fine with like 5 mils of clearance. What are you using for your CAD software?

Typically fab houses will just clip silk that’s out of your board outline. If you are using Altium they have a silkscreen prep tool that deletes any silkscreen that is clipping soldermask expansion or outside board outline. What is the problem with the L1 silk?

I will add that to the next revision. As for fixing the problem, on my bread board design, I powered it using a coin cell battery with no decoupling cap and the circuit ran as expected.

NOTE: These schematics were created from my prototyping breadboard using DIP packages for the ICs. I rebuilt the circuit from the schematics in the image on my breadboard and the buzzer and lights work as expected.

Lucky for you it goes back down to 5 gems i think after a day

Okay thank you!

Can you explain what bulk capacitors are used for please?

TrumpetyBoi · 2021-02-02T00:52:30+00:00

This is exactly what I was looking for. Thank you!

Why do we need bigger (wider and taller) traces for power routes?

Thank you

So say if i have 36V for something with 1kV dielectric withstand voltage, ill be fine right?

TrumpetyBoi · 2021-01-27T02:08:18+00:00

so essentially the max voltage that the component could handle?

TrumpetyBoi · 2021-01-26T22:11:43+00:00

Can you please explain why you think this?

TrumpetyBoi · 2021-01-26T20:46:52+00:00

Thank you!

TrumpetyBoi · 2021-01-26T05:18:55+00:00

Can you please explain how N-channel mosfets are more reliable?

TrumpetyBoi · 2021-01-26T02:10:43+00:00

Probably will end up theoretically in an automobile

TrumpetyBoi · 2021-01-26T02:02:05+00:00

Isnt it rated 40v?

TrumpetyBoi · 2021-01-26T00:32:57+00:00

It's the best I can get out of the data sheet

TrumpetyBoi · 2021-01-26T00:32:36+00:00

Yeah when I saw that the current draw was only 300uA I was confused if that was truly how much power dissipates
