  • A word of caution about water soluble flux. If not cleaned off with water (preferably hot) it will leave residue on your PCB that can eat away at the copper and cause trace and component faults. It is even more noticeable on fine pitch SMT components. When I used it in the past we always ran boards through a dishwasher but you can’t have non sealed parts on the boards like pots etc.

  • “In Canada, you go to grocery store…"
    So just wait, you don’t have debt and credit card pin pads in the states? You likely could have helped catch the person by narrowing down who you sold that module too in that part of the country (with proper legal paperwork).
    Overall an interesting article to read since I myself have been in the electronics field for over 10 years.

  • I like how you used the top two circuit boards. I always use to just use a bland board then sit the test board on top and use a cheap clamping device to hold it down.
    I do have to say I am a little disappointed in your production area. No static straps on employees (I am guessing no heel straps) also over top fume extraction. Fume extraction from the top just draws all the harmful vapors right past the operators nose.

No public wish lists :(
