content: Do JLCPCB not realise that the natural reaction to their annoyingly active ad banner is to curse them and move it off-screen ?Update :Finally found the fix I wanted, at least for chrome-based browsers.https://chromewebstore.google.com/detail/animation-policy/ncigbofjfbodhkaffojakplpmnleeoeeThis does what I used to be able to have on firefox : a single animation and then stop, applied across the board with no special clicking or scripts to write. Abusive webmonkeys still make it happen on every page opened but at least it's not jittering away constantly on the edge of vision.

content: I hadn't even noticed it until you mentioned it.It isn't hard to become blind to advertising, which is why some sites force modal popups or self playing videos with sound defaulting on.

content: Sorry, you might not be able to stop noticing it nowWhat you say is true but it's also a kinda dick move.

content: I have not seen any ad banner here for a long time. Both uBlock Origin on my PC and the Samsung adblocker on my phone suppress them without any further configuration.

content: Interesting. I use Brave but those are one of the few things that get through. I presumed they were served from the forum itself which is why I mention it politely rather than try to block them.The banner right at the top did go away after being shuffled for a while but I currently see three banners near the top of each page, one for jlcpcb (which is really annoying), one for lattepanda (which might be annoying were it not for jlcpcb doing all the attention-grabbing) and one for multimeters which is perfectly fine and sociable because it doesn't move.It used to be possible on firefox to have animations run just once and then stop, which was a nice way to de-fang these things. Much less irritating. I don't know how to do that currently. However I think changing pages would make them run again.

content: I see no JLCPCB ad.But i can tell about the last experience i had with them:Traces were 0.32 instead of 0.4mm. I complained about, and showed them pictures from my microscope. They played stupid, because they couldnt find "C2", were the trace was underneath. After a lot of messages, they said 20% tolerance is, as stated on "their" website. But nothing stated that, on that i got displayed on the website.This tolerance cant not really be applied to tracewidths. Because on every different trace, there would be a differend deviation (in percent). Maybe i should have added some 0.1mm traces? I guess so!Next time i try PCBway.

content: Quote from: eTobey on October 04, 2024, 11:13:47 amWhile undesirable, some variation is not unusual, even for more expensive PCB manufacturers.At my old work, we ordered some quite expensive, impedance-controlled PCBs from a European manufacturer, and the variations in trace width were dramatic. (We had to send them back since they did not match the impedance specs.)

content: Quote from: eTobey on October 04, 2024, 11:13:47 amFWIW, two years ago I ordered a flex PCB from PCBWay where a long trace was to be used as a low-power heating element. The actual trace resistance came out 30% higher than calculated.Anecdotal evidence, and probably a combined effect of trace width and copper thickness. But the tolerance was on the same scale as what you got from JLCPCB.

content: Imagine paying a whole two dollars for PCBs, and everything was functional, but... the trace widths were slightly off.Horrific.Quote from: ebastler on October 04, 2024, 12:16:21 pmYeah there are so many things that feed into that, copper thickness, width, purity, whatever. I just made the assumption they're going to skimp on the copper and added some shorting links to tweak the resistance down, if needed. Or you can start low and PWM to hit power target.
