  • Hi one of my computer buddies arrived with this card ACA500PLUS

    looking i see one of the CF sockets has a few pins pushed in and bent /disconnected {too far gone} ....{*diot 8)}

    anyway it does happen


    so the socket is marked CF-50P now ive looked and looked

    and cat find this exact type

    its a bit of a strange socket


    so the long and the short of it

    is i need a new socket if you have one to spare

    or the exact part number of the socket used


    or better if you have a link i can buy one

    putting it on etc.. isnt an issue for me


    any help appreciated and thanks in advance...:)

  • reading what you said about hi quality smd desolder hot air in the link above not good! with me


    you just need a craft knife fine side cutters and clip off all the plastic leaving the 50 pins connections bound
    and just the sockets metal mounts

    a 350 deg big tip too remove them

    and a fine .5 or 1mm tip 280 and some flux liquid

    to dress the pads and remove the old spent pins and solders


    mag glass and a bright light!!

    no hot air smd tools required

    and ill tell you something



    i never take a socket off with hot air for sure it just wont happen clouds of smoke etc

    IR fries them in a few seconds

    clip and purge all the plastic carefully with blades and clippers manually then dress the pads for a new one

    mount and hand solder with the right rhos stuff and 375 deg .5mm tip
    i have hot air and IR both are unsuitable for removing the socket

    or even re-fixing it {flux liquid and 0.5mm solder}

    best both done with nerve and mag and light and fine tips


    sorry to disagree


    also these sockets are very low quality tin plated soft copper
    nothing like other cf card sockets with hard drawn gold plated
    im not complaining for sure :) wrong advice ..

  • i think a 0.5mm bead of epoxy across the rear of the cf cards slots

    may help retain the pins


    seems easy to rough hand them


    still heavy hands are heavy hands


    ill investigate how it happened see if cf handling can be improved

    ie is it a heavy hand or lack of glasses and a bright light


    not good but it is what it is

    from what i see a very well made design


    it had as it was 4 pushed in pins

    nothing bent up


    not a strong socket but the pads did not rip up

    the pins back end deforms

    hence the epoxy suggestion

  • I suggest to check your SMD equipment for proper temperature control, as I cannot confirm "smoking" these parts away with properly-controlled hot air. I don't use IR, but that should also work fine, as the plastic of the CF card connectors is RoHS compliant, meaning that it can withstand higher temperatures than non-RoHS parts.


    As for the metal of the pins, I find it hard to believe that you call it "soft copper", as the hard metal is the cause for the pins breaking off when bent. So your "soft copper" description conflicts with the observation of pins breaking off if you bend them too hard.


    As for pins being pushed back through the plastic, yes, this is possible, and if you push hard enough, it's possible for every part out there. That's why there is a paragraph in the manual that says "almost no force required". As soon as you feel mechanical resistance, stop pushing, and the CF card slots will live for many years to come. The ACA500 is out there since 2013, and most, if not all of them are still in use.

  • ok thanks for the advice


    ive already removed the old socket and dressed the pads ready for the new one
    and my way


    i get 100% success doing it this way for 25 years

    i would use hot air or IR if i wanted to keep the old part

    just dont like hot air in a tight space

    seen many disasters arrive with hot air damage

    i use IR to re-ball the chips in PS and Xbox

    and hot air for ataris and also sometimes amigas

    mostly too dress over battery damage!!!!!!!! fer fek what a mess


    it has its uses and its limits

    just dont like heating anything i dont need too

    i could see the point if i had the exact fitting for the hot air

    but they cost like 100$ ish each sometimes

    my method works if you dont want too tool up for what is a simple job

    and avoids de-lamination of layers of pcb or thrus


    each to their own i suppose


    your very helpful ! thanks


    ps i did find an epoxy for car use comes in a tube with a funnel nozzle

    will produce a .25mm bead and cures in about 1 half mins in air to firm and 24 hrs to rock hard

    and ill run a line of it on the back of both sockets

    as i said its not me that broke it but i feel this will help negate pins pushing in
    nothing bent just pushed in

    think this ones been fortunate pads didnt rip

    your pcb process is very good


    now i feel bad im not havin a dig in any way

    and im sorry if i offended your design etc


    just trying to add improvements and future proof additions

    eek...... sim says sorry..

  • (link removed)


    cheep and cheerful gel spread 1 min to go tight 24hrs rock tight

    has the properties of both super glue and epoxy


    so bonds very well to both plastics and metals


    try it out!!!

  • For anyone else reading this: Using Checmicals like such a super glue is an "at your own risk" action. While it's not 100% clear what the chemical compounds are and what they do to the solder/plastic/PCB material, iComp cannot assume any responsibility for the outcome or long-term effects. Note that the recommendation for that specific brand or the use of epoxy or other glue in general is NOT backed by iComp.

  • its not cryano acrolate !! super glue...

    developed for sticking tiles too the space shuttle

    is better


    look here for the formulae (link removed)
    so quite a safe compound to spread thin as a bead.. from a nozzle thats graduated to size


    over week pins back ends of sockets
    and ill use it many times more


    omg


    i recommend a week off

    so ill take one
