Disappointed with JBC
« on: September 01, 2015, 02:43:55 pm »
I have recently purchased a brand new JBC CD-2BD soldering station. I have read mostly positive reviews/opinions about JBC products and that particular station in this forum and some other places. I guess all the good things are already mentioned by others, so I would like to point out something I did not like.

1. JBC claims their cartridges have superior thermal response and shows a graph as a proof where we see how in 2 seconds temperature rises from 20 to 350°C. My collected data shows that is a marketing BS. It takes 7+ seconds to do that (see the graph attached).
2. I have contacted JBC about that more than 2 weeks ago, but I have not received any response on this matter. I was really disappointed that they showed no interest and did not care to respond.
3. I have found two major issues in their "JBC Manager" software:
    a) It looks like temperature displayed on the graph is not always actual temperature. It is especially visible when temperature is dropping in Sleep mode. For example, on the LCD screen I can see that temp is 150°C while at the same time on the graph it shows that it is 225°C.
    b) It loads my i7 CPU by ~40% when it draws a simple graph. It does looks suspiciously high.
4. Other less important things:
    a) No change log is provided for firmware updates, so you do not know what was fixed. Not that it is very important, but it seems to be a common practice to provide it and hence I a missing it.
    b) There is no "Process Alarm" function (if the actual temperature leaves the preset temperature window, an acoustic signal is generated) that ERSA i-CON stations offer. I think it would be handy and could be easily added with the next firmware update if JBC decides to do so.

Did you measure the temperature response externally at the tip?

The graph was made using software provided by JBC. I have double checked the readings on the LCD during the heat up and it was also about 7 seconds.
After reading your question, I have measured temperature at the tip using Fluke 80BK and, without doing a proper setup, can say that it does not heat up in 2 seconds, not even close.

As much as I can find, JBC advertises 2 seconds for T210 handpiece, not T245 which your station seem to come with. The trap is that you likely have read the advertising without any conditions specified. Just that soldering stations can reach 350oC in 2 seconds, that's all. This one? http://www.jbctools.com/heating-system.html
But if being more specific....
http://www.jbctools.com/pdf/JBC%20Top10.pdf
Quote
A standard station needs between 10
and 90 seconds to reach 350ºC,
while any JBC station equipped with
a T210 handpiece reaches the same
temperature in only 2 seconds.

Yep it's just marketing fluff, you can find some graphs using the T245 here versus a few other irons;

Their customer service is a little hit and miss, they seem to screen like an Olympic drug tester, it's a shame really.  :-DD

Thanks for the PDF, figured out JBC have no shame. I just checked JBC vs ERSA comparison in this document and what do you think. Heat up time is almost equal, but when soldering ERSA sucks, riiiight? With a tiny detail, tips used, 3 mm JBC chisel cartrige vs 1.6 mm ERSA chisel tip :palm:
Tips on the pictures looked a bit off in comparison, so I searched for the part numbers specified, and hell yeah. Marketing maggots.

wraper, I have done my homework.
1. If you open a page where JBC advertises its CD-2BD soldering station, you will find the following written: "It works with the JBC exclusive heating system". That "exclusive heating system" is described as one that allows to heat up from 20 to 350°C in 2s.
2. If you open an official brochure for Compact line soldering stations, you will find the same advertisement of its "exclusive heating system".
3. CD-2BD offers peak power of 130W, while CD-2SD - only 40W. So, I doubt that CD-2SD, that comes with T210 handpiece can offer any better results.

What conditions do you have in mind? In regular every day use it does not show the advertised performance.

UPDATE: Thanks, deadlylover! That pdf you linked illustrates exactly the same heating times  :--

Using it with T210 handpiece.
I don't see there that they would say T245 heats up in 2 seconds anywhere you mentioned. Moreover if you attach some really beefy cartrige, it will be much worse than 7 seconds. If you attach T210 handpiece to your station you'll have those 2 seconds, because tiny cartridges with very low thermal mass. You just bought on a 2 seconds bait without researching further if there is a trap.

No you haven't. When there is only one particular model mentioned, they don't say anything about two seconds, like over this link  EDIT: actually there are those 2 seconds, not in the spec but in advertisement (general for technology, not model) on the bottom. In the brochure you mentioned where are those 2 seconds to 350o C, there are multiple models in the catalog.
You wrongfully assumed (as their marketing department wanted) that every JBC exclusive heating system = 2 seconds to 350o C which is not.

All the marketing bull aside, it is still one of the best handsoldering tools you can buy, so really no reason to be disappointed, imho...  :-//

Yeah, rather to be considered as the lesson about marketing for the next time. You won't be able to buy any better anyway, so don't be disappointed about making the wrong choice.

I have the modular line for both the soldering station and the rework station and I'm quite happy with them.  I get the concerns about the fuzzy marketing, but all in all, it's the best performing station I've ever had the pleasure of using.

wraper, based on your logic:
1. A guy sees a car advertisement where it claims it can do 0-100 in 4 seconds.
2. A guy purchases a car and realizes it does it only in 20 seconds.
3. A guy asks for explanation and gets an answer that he saw a red painted car in the advertisement and he has order a black painted one and that it is his fault he assumed they both will have the same characteristics.

In this case you will say he has made a wrong assumption, however, I will say he was deceived by a false advertisement. Yeah, you can say that they have sophisticatedly fooled me once, but they will not have a chance to do it again - simple because I will go with other brands ;) You can loose trust quickly, it is much harder to gain it back.

Impressively quick heating time was one of the major factors why I have chosen this station over the other I was going to buy. So I am disappointed.
Just to clarify, it is not the bad station, but not the best either, at least not for me.

You seen the advertisement that xx model car can do 0-100 in 4 seconds, have climate control, uber navigation, yada, yada.
You buy it, and then realize that you bought an option with a smallest engine which do only 7 seconds, no climate control, no navigation option, and crap audio system  :-DD
But it's still the same model  :-DD This is the real world  >:D.

This is still fastest heating in the class. You can use T210 handle with 2 seconds heat up (or a bit slower weller, etc), but they good only for some tiny stuff. Nothing with the same size of tip will heat up faster than this one.

Well, that analogy is distorting things a little, isn't it? How about this version:

1. A guy sees a company brochure saying "Porsche has the only series production cars which go 0 to 100 km/h in less than 3 seconds".
2. Guy buys a Porsche SUV and is disappointed that it takes 8 seconds to accelerate.
3. Guy gets the explanation that the 3 seconds apply to the company's fastest production car, the 911 xyz sports coupé.

Still not nice, but rather typical selective truth in advertising; and the difference in performance between models makes obvious sense from a technical perspective.

I use ERSA I-CON stations BTW. So yeah, I can see how one can decide to go with JBC thinking 2 vs 9 seconds, it's waaaay better. While in reality it's just 7 vs 9 seconds when comparing apples with apples, and ersa tips are wayyyy cheaper.

If I may ask. Is your life so busy or your projects so tightly timed, that a 7 second heating difference matters? Who cares whether it takes 2 or 9 seconds to heat? By the time I've sat down, taken a sip of coffee and found the component I need to solder, the 9 seconds have passed several times.

Just for information: I also use an Ersa iCon Nano.

Also, that's cold start, right?  The JBC's go into energy savings when it's in the cradle, but that temperature is still pretty high, and so when you pull it off the cradle, it doesn't have to go very far to hit your set temperature.  I feel like mine hits target temperature after pulling it off of the cradle in a mere second or two tops.

Cold start or start from Hibernation.

I think your analogy is distorting and not by a little bit, but we are all entitled to our own point of views, right?  :)

Btw, I just got this "lovely" exception, I guess JBC got angry on me for my complaints  :D

I run my Ersa at 360°C most of the time. It sleeps in stages. There's one at about 250°C, then somewhere around 100°C and the final step brings it to 50°C. It takes about 5 seconds to get back up to 360°C with a 2mm Chisel tip from 50°C. That's about the time I need to prepare the component.

Heat up times are about as relevant to real world usage as 0-60mph times. They give a hint of performance, but aren't really that useful a guide.

I don't know about you guys but MY time from "off to soldering" (get the iron out of the stand,  solder in the right position,  light etc is a lot longer than 2 secs,  HiHi.
Happy JBC user, esp heat transfer rate from a tiny handpiece.
Whoah! Watch where that landed we might need it later.

My time requirement is about 1 sec, I am not sure why people first grab the soldering iron and THEN reach out to the component or do whatever adjustments. When I want to solder I am ready to solder, the only delay is to get the soldering iron to where it needs to be.

Having said that, JBC is OK to me when waking up from sleep when I perform a work, but certainly not from cold state but I am not worried about cold state warm up time as much as I do for wake up.

No doubts thermal performance is better than my Weller EC2002, but overall I like Weller better. I could throw the handpiece across the bench and it would land right into the opening of the holder. With JBC I have to handle it like a baby, carefully taking out and putting back in to the holder. I have no clue how people on assembly lines use it, it is certainly not designed for any type of abuse.

Just make sure your iron sits in the holder right, or prior to come back to an oxidized useless tip. With a multi channel station, make sure you don't bump the cords either.  We retired our JBC units at work for metcals after they keep burning though tips, and the newer units got flaky in various manners.  Personally I think the small metcal tips work better on heavier loads than similar sized JBC tips. I did prefer the jbc tweezer design, vs the metcal design though.

Just my $0.02.

I think TS has a valid point, if a company claims X and in practice it is Y >> X then you can complain.
It doesn't matter what X is, even if it is the color of the thing, it is misinformation.
In this case X is a parameter that is important since each and every company that sells solderstations benchmarks this.
