And size for several capacitances are correct

Re: Nichicon HM/HN/HZ scheduled for discontinuation

Many of the datecode s are 15xx or 16xx, and why I have confidence is that I saw the shop appeared to be well managed with other surely legimate products and witnessed staff restocked some other Nichicon caps from what looked like a logoed bag.

If they really are fakes, then whoever made them looks like they put a pretty good amount of effort into them. So even if they are fake, then I doubt they would be that terrible.

Not nessarily. I could see them putting $1000 into making them look legit and less than $0.01 into making them actually work well.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

They look pretty genuine to me as well. I couldn't read the datecodes, though. Are they with very recent datecodes? If so, that is indeed a bit concerning. But perhaps they could also be a custom order??

I guess, use them at your own discretion. If it is for repair of personal electronics (or ones where a disruption in service will not be critical should these caps turn to be fake and fail), then you can give them a try and see what happens. If they really are fakes, then whoever made them looks like they put a pretty good amount of effort into them. So even if they are fake, then I doubt they would be that terrible.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

they appear authentic, but the fakes are getting good these days. Considering Nichicon discontinued these years ago, finding them with current datecodes on them, I'd be very skeptical of their legitimacy if I wasn't getting them directly from nichicon or a very trust-worthy vendor.

They were found in Tokyo, Japan

Hope the resolution is high enough

Re: Nichicon HM/HN/HZ scheduled for discontinuation

they're fake unless there was some small specialty run made of them. where did you get them, and lets see the bungs.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

the build quality, specs and size as well as the store appear to be very genuine.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

wait, I am in Tokyo Akiba now and a large electronic store is selling nichicon HZ with datecode 1606

Re: Nichicon HM/HN/HZ scheduled for discontinuation

When you're trying to wick lead free solder from a small circumference , narrow wick is a must. I can get away with 0.075" wick in a pinch, but it's much easier with 0.050". This is of course the case with modern motherboards.

Thanks for the answer. That makes total sense now, thanks.

I take it you're kinda shoving it into the molten solder down into the hole instead of on the top of the hole, flat against the board. Yeah?
Any 'ol brand of wick good so long as it's a major brand and is empregnated /w flux. Or is one brand/type better than another?

Re: Nichicon HM/HN/HZ scheduled for discontinuation

Can I ask why it's advised to use such an eensy weensy braid size, as opposed to the bigger stuff?

If you have no wick, then you can leave what's left of the old solder in and rock the cap in while holding the iron to the pad from the other side of the board, but it's much easier if the holes are already clear and you just plop in the replacement cap and solder it in (eventhough this takes more time), and there is also much less risk of ripping off the bottom part of the pad this way.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

Yeah, smaller diameters are cheaper... what I like to use is 0.075". It seems to be a good general purpose braid size...

My current (and the previous) braid was this:

(and yes, it is pre-fluxed)

Ratdude,
Can I ask why it's advised to use such an eensy weensy braid size, as opposed to the bigger stuff?

One thing I have noticed is that the stuff that comes in the tinier things (like they have at radio shack) is a much crappier braid than what comes in the more traditional spools (like what I linked). It seems to be a much looser and less effective braid (often w/o flux) from my experience.

Yeah, I stupidly bought the RatShack stuff, it was all I could get my hands on here. It left a bit to be desired, but really I think more than anything it was my iron. It definitely pulled up solder. But I wouldn't say so much that it "wicked" it. Not that I'm singing its praises or anything, but it does look pretty tightly packed, then again I have nothing to compare it to. I know I had to crunch it and spread it pretty good, like Chinese finger cuffs, to get it to spread out. Seemed to work better that way, although I have now learned it seems you aren't supposed to do that. OOPS!

The RatShack stuff was 8.5MM in width, which is just shy of 5x wider than what you use.
Being not much larger than most recommended solder sizes. Maybe 2x as wide.
Wouldn't you just go through the smaller stuff 5x faster, more feeding, more cutting, more frustration?
Please do tell, I desire to learn.

I have tried finding a video and searching the forums, but not much luck.

I've never worn glasses when soldering.

pft, Iv'e slopped solder all over myself countless times (have a few scars from that too xD)!

Actually, I just realized that it's been months since I last burned myself on the soldering iron, getting better at it!

Re: Nichicon HM/HN/HZ scheduled for discontinuation

The only thing I don't like about desoldering braid is that sometimes the braid lets go from the solder all of a sudden, and it flings hot solder in the air.

Always wear glasses/safety-glasses when soldering! Its a MUST!

Re: Nichicon HM/HN/HZ scheduled for discontinuation

So do I. I guess you have a fancypants iron with the expensive tips. The $6 one I got from China (Which works fantastically) has a relatively blunt tip (Thing is very durable though, I don't think I'll ever have to change it).

Mine is a Weller W60-P that I inherited from an Estate (Long story). The tips weren't too bad ($4.70 a pop from newark). The iron't temp is regulated by a magnet (curie point) at the end of the tip. My two tip sizes are:

1.57mm Chisel- it runs at 700C

3.18mm Chisel- it runs at 800C

I haven't had the iron that long (I've had it 10 months but usable for only 4) but it so far the tips have been been doing great, other than the usual color changes to the tip's non-soldered body there have been no signs of wear.

Both tips can do the braid OK, the larger and hotter one running a lot better for obvious reasons.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

radioshack braid is unfluxed garbage. Complete ripoff.


.75 works well for me... no heat loss issues... then again, I have a 60W iron.
