  pt  2:51 PM a short version :) selective soldering, pick and place, a few odds and ends

  wa4jat  2:53 PM Cool video :-)

  anfractuosity  2:53 PM cool, not seen the soldering process that's performing on the bottom before

  DPM  2:54 PM Serious question: how do PnP machines not scatter components all over the place when they take the tape off? Any time I try to peel that tape back, everything goes flying.

  wa4jat  2:54 PM I have setup wave soldering years ago but never seen selective soldering like that.

  Jimb  2:55 PM Seemed like there was a lot of bridging

  captain.morgan  2:55 PM neat, I've seen some cool demo videos of laser selective soldering for SMD

  tannewt  2:55 PM Hi folks!

  anfractuosity  2:55 PM @Dan Maloney tape?

  captain.morgan  2:55 PM wonder if that's withing the realm of desktop these days...

  DPM  2:55 PM Yeah, the clear plastic cover over the components

  Jimb  2:56 PM The tape holding parts in the strips

  anfractuosity  2:56 PM ohh

  ladyada  2:56 PM static can be an issue! the feeders are metal so that helps a bit, but mostly there's drops and you do optical inspection to deect it

  Jimb  2:57 PM I imagine the rigidity of the fixtures and the way the tape is peeledd back is important too

  captain.morgan  2:58 PM my desktop has a leafspring that pushes the tape up and only a small opening to pick the part, that keeps the tape from moving virtually at all

  ladyada  2:58 PM yeah its pulled directly back with a sharp corner. im sure they've worked on it a ton. we also dont go under 0402

  captain.morgan  2:58 PM ...desktop machine...

  Jimb  2:59 PM saw a 201 once. like a grain of sand!

  ladyada  2:59 PM 01005 boggles the mind

  Jimb  2:59 PM It was stuck to my bench by the previous owner. Wondered what the bump was
