First and foremost, Welcome to the Badcaps Capacitor Search Engine & Forums!

New members that have activated their accounts have limited access to certain features of the site until established. Members with zero posts have no access to the private messaging system. Also, members with zero posts may not edit certain profile attributes, such as signatures. New members also may not create new threads. However, new members with zero posts have full access to all technical information contained on this forum, and that also includes attachments (images and files that other members have uploaded), and new members that have activated their accounts are free to post replies to existing threads. If you wish to create a new thread, the fix is simple! All you need is ONE post to be able to have full unrestricted access, and that can be simply posting an introduction of yourself or say hello in THIS THREAD. This may seem a little strange, but it helps keep spam and abuse curved. Please note, that it may take up to one hour from your first post for the limits to be removed. If you make a post and don't immediately see the restrictions gone, be patient. The promotion system updates every hour.

Please complete your profile after making your first post, with your name, locale, and other info. It's nice to know members on a first name basis, and know where they're from. Makes for a much friendlier environment!

Posting rules:

This forum was created to be a technical support forum primarily for the do-it-yourselfers who choose to repair their own boards. Any and all technical questions are welcome!

1) Please use the SEARCH feature!! Your question may have been answered in another thread! Please search first and see if it has!

2) When posting a technical question, be as detailed as possible in your thread. The more information we have about your specific problem, the better we can answer your question.

3) Please use COMPLETE sentences, punctuation, and grammar! Nobody is perfect, hence, a spelling error on occasion is no biggie. However, posts/threads that are unreadable will be deleted. This includes any and all forms of 'ebonics', leet, chatroom jargon, and 'text message' shorthand and slang. This forum is not a chatroom/text message, please use full words and complete sentences.

4) Keep discussion on topic!! DO NOT HIJACK THREADS! It's easy to do (I've done it myself a few times...) Lets try to keep it down to a minimal!! If you have something really off topic, that's what the lounge is for!

5) Keep things civil! There will be no tolerance for flaming, bashing, hateful remarks, racial remarks, adult material of ANY kind, and so on.

6) THE LOUNGE RULES! The lounge is a place for off topic chit-chat! If you post something that might be considered questionable or something you don't want kids to see, or something you can't view at work/school, etc, please label that thread *NWS* or NOT WORK SAFE in the thread title as a warning. The Lounge is NOT moderated, anything is welcome... Feel free to post rants, jokes, cars, hot women (remember the NWS warning in the title), or just about anything within reason. It's an open forum! Please refrain from participating in political topics if you have thin skin, they can get heated sometimes!! Remember that we have members here from all over the world, with many different views and cultures. Political debates can turn really ugly, and really fast, and if they degrade to personal attacks and useless banter/bashing, moderator action will ensue.

If you see a thread which clearly a spam bot posting that we have not removed yet, DO NOT click any links in it!! Simply click the 'report bad post' button, and it'll be taken care of, usually within minutes.

8) Account removals & closures: Since no personal information is given in the creation of your Forum account, requests to remove and/or delete accounts will be declined. Any requests for removal of threads & posts you created will also be declined. The reason is the missing posts can/will leave threads incomplete and fragmented. For the threads to be of help to others later on, information can't and won't be missing. However, if you inadvertently posted personal identifiable information in a post (such as an email address, real name, or phone number), please contact a staff member. In those cases, the post may be edited or removed, at the staff members discretion.

That's about it for the rules, the setup here is pretty loose. However, if you're caught violating any of the rules above, here's what will happen:

First offense: Warning by me or a moderator
Second offense: Banning for 1 day
Third offense: Banning for 3 days
Fourth offense: Banned permanently.

If you do something really dumb, or are just a troll, I will skip the warning and the temporary banning, and ban you permanently!

The rules are pretty cut and dry... However, if you have any questions about this policy, feel free to contact me.

    Remove excess solder


    Can someone tell me how (or if) I can remove this excess solder?

    I made a novice boo boo.

    The board is an edge board from an lcd tv, and it connects to the tv panel via a fixed cof strip.

    I had to remove a surface mounted multi diode chip (yes I did a bad job) but got some residue solder on the pins when cleaning it up with a ribbon wick.

    Can I get that excess off, as I believe it is causing interference to the panel, shorting or something, that effects just a small portion of my image.

    Any pointers please?

    Thank you

    Re: Remove excess solder

    To do this, there is a braid to remove solder.


      Re: Remove excess solder

      Solder residue like burnt flux flux? Use 99% IPA and a toothbrush.


        Re: Remove excess solder

        Thanks CapLeaker and lotas

        It is that type of solder wick that I used when taking off the I now simply use more with a warm iron?

        My worry is that when doing so, that it might try to remove the actual end tips that I require to still stay there?

          Re: Remove excess solder

          The pic isn’t very clear. To me it looks like burnt (black) flux that needs to be cleaned.


            Re: Remove excess solder

            Does this help?

              Re: Remove excess solder

              Put a lot of flux on there and clean that up with your soldering iron using a chisel tip or similar. If that is indeed solder it should stick to your iron, just clean the iron after every stroke. Then clean the spot with 99% IPA. When the flux gets brown and thick, wash it away and put more new flux. Be gentle on the tab bond. If you can select the temperature of the tip don’t run it full bore. 280C or 300C should be more than enough.


                Re: Remove excess solder

                Thank you for your reply.

                As you can see, I am only new at this, so please forgive the extra questions?

                When I removed the chip, all I did was heat up the iron, to remove the chip.

                I did not use anything else, and as the solder was melting, I used some tweezers to pull it off the board.

                I then got hold of my solder wick tape, putting that on the area, and then tried to soak up the remaining solder left over.

                I think(??) at that time, I must have slopped some of the solder off the wick, and onto those pin areas when doing so.

                It is now my duty to try remove that slop.

                I have not used flux before, so I need to buy some to try to clean it up.

                Do I have it right, following your reply, that I simply have to put the goo I am buying....

                onto the area, warm iron, and try to get solder off one wipe at a time, until it is gone?

                I only ask, because when I try to look at youtube videos, they seem to say to buy isopropyl 99% and try to clean it with that, by wiping or using a toothbrush.

                This is where I get confused, and don't wish to make my job worse, rather than better.

                Can you please advise again?

                My apology for being rather dim.

                  Re: Remove excess solder

                  first clean it with isopropyl 99% . then see how it looks .


                    Re: Remove excess solder

                    I think that connector isnt firmly affected with solder yet, so use toothbrush and any alcohol, and if you have hard sticked particles use a wooden toothpick to scrap it...

                    But, you must also clean your initial "working area" around chip, to see what is going there... I see some ripped pads, maybe bridges... you cant work without proper tool, I think some flux and be familiar with technique. Practice on scrap board before try to fix something.

                      It all cleaned up perfectly after using iso again, the set now runs perfect after following this thread...
