    I'd like to use hot glue to stick battery holder to PCB (motherboard).
    Can high temperature of glue (170 to 200 C) damage PCB?
    Any tips for using hot glue?
     
  2. Hot glue would not damage the PCB. Use sparingly however.

  3. Hotmelt glue is poured liberally over many types of electronic circuit
    boards in a production environment so, No - it's Ok.
    Allow plenty of time for the glue gun to warm up - more than you think is
    reasonable - otherwise the glue will not stick properly!
    Place a newspaper under the glue gun - it will leak stick to the table when
    warm enough!
    Whatever you glue must be clean & dry!
     
  4. Hot melt glue has lower a temperature then the solder that is used to
    connect the components. You should be sure the glue to be on its processing
    temperature and the objects should be clean and dry. (Like for every glue
    job.) Use a tissue and ethanol to achieve this. I prefer to use double sided
    tape to fix things like battery holders.

    Is it possible to REMOVE hot melt glue from a motherboard?? I would like to
    replace a Vartec barrel-type battery that was plunked into a blob of
    something and then soldered to the board.

    Another trick I've learned in spot glueing on PCB's is to prep the
    area with a bit of solvent to give it more tack.
    I use acetone on a swab. You can also use a bit of fine emery paper to
    rough up the glue point.
    low temp glue for low stress tacks on things like wires etc...
    High temp glue for glueing major items on like battery holders etc...
