    Default GBA1000 expansion board assemblying

    I have been asked by AXm77 to assembly GBA1000 expansion boards for him. This thread shall be updated as the assemblying progresses and also to exchange feedback after the transaction is done.

    Hi hese,

    Thanks for starting the thread
    I'm really interested in the order you build the board up. What are you starting with, the smd first?

    Hi ObjectiveD,

    first I solder the fine pitched smd parts (gpu, cpld chips, usb chip, 74ALVT16543s, memory modules) and after that the rest of the smd parts (other ICs, oscillators, capacitors, resistors, ...). And finally the through-hole components.

    - - - Updated - - -

    Noticed some minor quality issues with the turbo card PCB. There are a few spots on the PCB that have an excessive amount of solder mask paint (?) over the traces. The traces do conduct so probably not a problem.

    I don't see any problems in those pictures. Can you circle what you consider to be a quality issue?

    Oh yeah. That is a bit of a mess. I was more focused on the IC pin pads and missed it completely. Still not a problem though, it's just messy masking, it won't effect the function. It would be a problem for pick and place though because the IC wouldn't sit flat.
