    Tools & Caps - Worthwhile ?

    Done a bunch of reading and based on what I've read and what available to me locally I'm considering this iron for doing the caps on my Shuttle MB's :

    Weller WLC100 Station (40w ~900F)

    Two other options are the:

    WP35 Iron (grounded 35w)
    WES51 Station

    I'm guessing that the 40w station will get the job done well. But I'm new to caps and MB's. Let me know what you think.

    Also since I notice the Rubycon caps are out of stock here are the Samxon ones a good alternative ?

    I need the 6.3v 1800uF 8x20mm caps.

    I also found an eBay seller who had these:

    http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT

    Would that be a viable replacement ?

    Overall great site and forums and thanks for the info and opportunity to work on this !!!

    Not familiar with Weller models, I use HAKKO, but 40W is marginal, 50 to 60W would be better.

    A station is preferable to an iron.

    It depends on the board, boards with a lot of copper in them really bleed off the heat.

    Also the newer boards use that crappy lead-free solder which melts at a higher temperature. Always use lead-containing solder, and apply it to the old solder when removing caps.

        Bummer - that 40w station is under 1/2 the price of the 50w. But I'd rather go into this with good equipment than not.

        Okay so dont mess with those eBay ones then ? Is there a way to spot fakes reliably ? By specs and pictures those sounded like they'd be the ones

        Last since the rubycon 6.3v 1800uF 8x20mm are out of stock on this site - are the samxon caps of the same value just as good to use ?

        Thanks.

          Oh I also saw the reviews on this:

          Sounds like it might be good ?

            You can spot genuine vs. fake caps by carefully examining their labeling, top vents, and rubber bungs. In the ebay page, the caps had a "T" shape vent, where as real Rubycon have a "K" shaped vent. Additionally, the labeling on the plastic sleeve is all wrong. Wrong font, wrong color.

            It takes some experience to spot real vs. fake. In the mean time, feel free to post some photos. Forum members are always happy to help out.

            Samxon GC would be an adequate substitute for the Rubycon.

            If you wanted to stick with Rubycon, getting the 10V 1500uF MCZ would likely suffice as well. The 10V 1500uF has the same can size, so ripple handling would be the same. Capacitance is a little less, but unlikely to make a difference. Do not get the 6.3V 1500uF MCZ, as those are smaller in size and have less ripple capacity. I just realized after typing all that that Topcat has the 10V 1500uF in stock, and makes the same recommendation on the front page of the site.

            Another option would be Nichicon HN from Mouser:

              Thanks for the replies. I went and ordered a couple of those Nichicon just to be consistent with what I have. Hopefully I haven't mangled my board too bad with the removal earlier We'll see next week.

                I found that 40W is usually enough power to solder caps in motherboards but not quite enough to desolder them, even when 63/37 tin/lead solder is added to the joint to lower the melting point. 50W is enough for desoldering, but a regular 50W iron will overheat the tip and oxidize it, which cuts way down on heat transfer.

                I think the cheapest iron that will handle about anything is a 70W Goot PX-201 temperature controlled, about $50.

                  I used to use a WLC100 for my desolder works. But that's for monitor boards. They were thinner with less conducing layers. Since I got more experience and make some money on repairing stuff, I upgraded to WESD51. It has a digital temperature control so I always know what temperature I am at. Really nice addition.

                  I don't know much about replacing caps on motherboards tho. If you are a beginner I would suggest you get the WLC100 first, then sell it off and trade for the better ones.

                    That's a desoldering iron not a soldering iron.

                    Plus ALL Radioshack stuff is overpriced Chinese crap .

                    On the topic of desoldering irons unless your desoldering iron has a vacuum pump (more expensive models $100+) don't bother and use braid.

                      I got on of these when I was out of town and unexpectedly had to solder something.

                      Works well.

                        my 30w xytronic 258 does a decent job on things without heavy ground planes. i am thinking of upgrading to a station with a little more power.
