One Nation Under God Flag shirt
I remember doing this in 1978. I worked for a company in Mt. View CA (before it was known as Silicon Valley). We didn’t have PC boards yet. We silk screened gold and silver traces on small precut ceramic, then ran them thru a furnace. Back then, we each had an open jar of One Nation Under God Flag shirt to ‘clean’ the ceramic if we made a mistake (Don’t think they had OSHA yet. We also all smoked while doing this…ashtrays everywhere) Then silk screened dielectric over those. then silk screened resistors. then laser cut the resistors to get the right numbers, then solder/hand place capacitors/chips, then gold ball bond the chips to the printed gold/silver. We were making boards for missiles. That was 43 years ago and I can’t believe I still remember the process. I was just out of high school.

So serious comment, my husband is an electronics technician. I have seen him solder before, ya know iron and solder. I am watching this video and thinking “Why on earth are they ruining this poor circut board with glitter glue?!” Then I showed him this video.Today I learned that this glitter glue like substance is called soldering paste. This is a type of solder One Nation Under God Flag shirt that melts and fuses at high temps. It is used just like the video except “and maybe this just isn’t shown” it is typically melted on conveyor belt oven similar “but different than” what the cook pizza in at chain pizza resturants.My mind is blown!
