I designed many PCBs in pretty much this way in the 1970's. I used plastic stencils of various component pad footprints to help draw the pencil layout on the graph paper. For the final 4X plastic photo mask, besides stick-on doughnuts for the pads and black sticky crepe paper split tape for the tracks (crepe tape can be easily bent into curves as you lay it down), I also used "Bishop's graphics" which were stickers containing the pad footprints of various IC patterns. One difference from this vid was that the initial transparent film placed over the graph paper and pencil layout was a product called "rubylith" which had a thin red gel coating that could be peeled off the transparent backing. The first task after the rubylith was laid over the pencil layout was to cut through the red gel layer around all the areas of the tracks and pads using light pressure on a scalpel, and peel off the red film to unmask those areas - the red areas left would be the ground and/or power planes. The manufactured PCBs were two-sided and tinned but had no plated holes - we tried to feed tracks from top to bottom at the leg of a component that could be soldered top & bottom. If that was not possible a large via was placed that would later have a pin inserted and soldered on both sides. It was a matter of pride to design a board with no vias and no wire interconnections. A very large bellows type studio camera on rails was used to photograph the completed artwork to make the 4X reduced photo-tool directly on a photographic litho film plate (I think it could take up to 750mm square plates). All original artwork was kept so that any required modifications could be made by lifting and re-arranging the tape and decals on the original artwork. There was no silkscreen or soldermask produced at the company I worked - all boards were hand placed and soldered.
Tektronics, Hewlett Packard, Fluke, Rohde and Schwartz and Racal. Thank goodness I had the opportunity to use them all at their peak in the 70s and 80s.
Their board making technology is primitive compared to what we do today, but a great deal of Tektronix equipment made in the 60s is still working perfectly. The quality of their circuit boards, and of every aspect of their construction, stands the test of time with ease. Nobody ever made better, more intrinsically reliable electronics than Tektronix during the 50s, 60s, and 70s.
I have been designing pc boards for 45 years now. I remember well the days of light tables and 'decals'. Taping by hand...But now, its all done by CAD, of course. With the densities of todays boards, I dont think it would even be possible to do them by hand anymore. Thanks for a walk down memory lane.
Yup, taping up PCB artwork at 2x using Bishop graphics materials including red & blue mylar tapes and IC pad patterns for double sided PCBs in 1 artwork, multilayer a different ball game! Still got some from 1978! LOL
Light tables helped you see thru the layers of paper and mylar, but also to see if cut lines on tapes actually created fine gaps (.001 - .003") that etch out and create open circuits where you least expected it!
I think with a 4x or 8x grid it would be quite doable. Heck I’m hand-painting 0.4mm pitch (micro USB sockets) directly on boards, with only some difficulty.
Lucked out in hi school and learned to design and etch simple-ish PCBs back in 1974-78 in electronics shop class! However, as a job it was a lot tougher, not fun and games, almost pulling my hair out to cram MSI & LSI ICs shoulder to shoulder into tight PCBs fast and not make any track errors! Thanks to my hi school instructor Bill Ashton!
This video is so freaking awesome - I always wondered how they did this before computers and CAD/CAM became available. I think this video should be a candidate for digital restoration - the colors, fading, brightness, etc. make it hard to make out things sometimes.
I found this really fascinating. Thanks to Mr Carlsons Lab's channel for sending me to this link. I wish I found it sooner, lots of new videos to watch now! Thank you
And here's a video of that machine: th-cam.com/video/2sm_qdeconI/w-d-xo.html Though more more processes actually save on time and material by disposing of the wires connecting the components to the board: th-cam.com/video/BepAMlrJwXI/w-d-xo.html
This is amazing. When I was young (about 25 yrs ago) I drew the PCB very similarly. At that time, it was awesome, CAD systems did not exist. Each line, each hole was drawn by own hand.
@@rock3tcatU233 That is true, but not everyone had access to such programs. Most things TV, radio, etc. were made this way. This method was used in the 80's - for sure in our country.
@@rock3tcatU233 They were generally very expensive. My first CAD software was XCad on the Amiga, late 80's and even that was a big spend for me, I plotted boards on an A3 pen plotter using special pens and latex based ink onto polyester film (if you weren't scrupulous about cleaning the ink out after, you basically wrote off an expensive pen), for some boards I plotted them at 2x or 4x and then got them photo reduced by a local printer, now I design a board in a few hours, email it to China and wait for it to show up in the post.
In the late 70's part of my job was doing pcb layouts with tapes,interesting,sometimes it would go well and layout all worked in harmony,other times you would scratch head and do some in depth thinking,The idea was to achieve a layout with no links and no right angle tracks,as these could lift during production.only 2 layer boards.I loved my job and stayed with the company for 13 years,doing various jobs ,prototypes,with wire wrap,field trials.Inspection,testing.Drawings.This film brought back good times.Thank you.
People, this was a time when America was GREAT! We did a lot of what is done today by automation by hand then. Tektronics was the world most advanced and highly quality controlled manufacturing that is sot of mimic today. Those days are gone and the young will never know. Sad!
great video, i started drafting double-sided PCBs in 1978, but I used two coulours of ink red for bottom and blue for top side, drafting was done on 2:1 scale or even instead of dotted lines and solid lines, then two coloured lamps in a lightbox could be used to see only one side or white for both. this was before 1984 when my employer bought AT&T6300 (Olivetti M24) and Smartwork PCB cad software but the 4 pen plotter with 4 colours of pens was still used .
I sat down with PCB designers to show them where the traces go from 1981 to 2007. In 1995 that guy was my boss at a start up who would yell at me, "No more abstractions! Point where you want the trace!"
That's pretty cool that they used a negative of the trace as a resist, plated more copper and then gold, and used the more inert gold as the etching resist.
Yes. I found the gold plating in the plating process very interesting. I remember Tek progressively reducing the areas being plated with gold when they introduced selective gold plating process for switch pads and similar areas that "required" it getting gold.
yeah this is orders of magnitude worse than the cheapest PCB manufacturers now. +/- .002” is garbage…and look at all those manual steps where people have a chance to screw it up.
So amazing! It's so very cool (and enlightening) to see how the basic interfaces and workflow in the CAD tools of today map almost directly to how the original artists constructed PCBs. I found the trimming (i.e. DRC error resolution! ) of the pads at @7:08 to be especially entertaining. I only wish the video were of higher quality!
..Well....back in the 1970's, I worked at Burgmaster.....we had NC machines in the machine shop that used the same Mark Century controls like these here at...12:30....! I was an Electronic Tech. and used Tektronix 'scopes....even the Burgmaster Turret drills back then still used that punched tape...
Incredible skill and craftmanship - for all that we have gained in convenience through technology, I can't help feel that the inconvenience of it all was an inspiration to invention. Fascinating times indeed and a quality documentary the likes of which are rarely seen nowadays. Thank you for preserving and sharing this.
Wow this is way back when Americans proudly stepped forward to be the leaders in the new world of technology, before they started eating exported soy and allowing all of these noble dignities to be exported to India.
Tektronix PCBs are among the best from that era. The one seen at 27:05 is for the 1A1 plug-in unit. There are many other boards shown in this video which I don't remember though. (edit: typo removed)
Tektronix has always been the 'gold' standard in scopes. Very well made. I picked up a used 2215A (from the mid 80's) at a garage sale. It still works like new. Its my main workhorse scope, even though I also have a new digital scope.
Yep ! Heavy Trace ,Pads and threw holes. I have never damage a board while replacing many components on the 400 series i've worked on.. Those early Tek Scopes were designed to be repaired -recapped over and over.
Interesting that they gold plate first and then use the plating as etch resist. I think basically all modern processes apply the surface finish to a board that's already etched and has solder resist on it.
It is only possible to electroplate when all the areas to be plated are electrically connected by the bulk copper. The more modern processes use electroless immersion plating, which will work with separate traces.
@@bobweiss8682Wow it's really been 3 years! In the meantime I've learned that modern processes sometimes *do* electroplate, but they achieve this by having temporary junctions between the nets to be electroplated that are then drilled out or routed off. A great example of this is video game cartridges, especially for the NES and Sega Genesis, which are electroplated hard gold for contact durability.
@23:58 -In the future, a machine may replace many of these hand operations, many workers will stay at home, and those who will work will do so in the east.
Amazing how nobody in the entire factory appears to wear any protective gear. Imagine this nowadays. No gloves working with acids and stuff? No radiation protection alongside that layer thickness detector? No inhalation protector worn at where the glass-fiber boards are ground to size or where manual soldering work is done? Wow. Wonder how this affected the life expectancy of the members of the manufacturing team... well, those were the days, right?
The Japanese avoided using double sided boards as much as possible: their approach was to install jumpers on the component side of the board. This reduced costs considerably, and I would believe bypassed American patents on electroless plated through hole double sided boards. The circuits were just as reliable, in some cases even more so, the Japanese products cost considerably less, and hence their eventual complete takeover of the international electronics industry.
You might be right but bear in mind which company made this video: Tektronix. Not exactly consumer products. Your everyday household radio was probably not made exactly the same.
You still see single-sided phenolic substrate boards. Often seen as cheap, but you do actually find it even in relatively high quality power supplies.

My dad had this electric eraser in the '60s. It used a stick of rubber eraser about 8" long held in place by a slip collet. IT had a line cord for AC power and a switch on the barrel to activate. I think K + E was a big drafting equipment company that sold them.
@@atschirner Wow, thanks for this detailed story! I also noticed that device and for a second thought it could be one of those obscure laser erasers. But an automatic Keuffel & Esser rubber eraser is at least as cool :D
This was our way of doing things then. Until better ways were figured out..it was the best of our abilities,and skills.. We took pride in our work then..now we let machines do the skilled work..its a shame we've become so lacking today..
People complaining about the low res,cricky just look at the moon landings,they were crap res.It was hideously expensive to have high res back then,and im talking above 240P , just enjoy a marvelous film..
So all industries should be today, not just American, but the world, what is wrong with seeing American workers, creating an American product of quality and value? Automation produces big gains for only a few, creating only unemployment and poverty for many others. Other times ... some would say ... in fact you can see the results .. For me we have already done too much, I would say that the time has come to do a downgrade, I would gladly give up all the useless technology of today, just to get back to that reality. Certainly I would not allocate billions of dollars to finance a trip to Mars, down here there are far more important problems to solve, first of all, the health of the most beautiful planet in the solar system and beyond. , the earth..
I worked there, 11 years, I have to admit I got a lot of fond memories, but it was a Lowest paying lousy management place in the world. Best thing I ever did was best. Best thing I ever did was get out of that place.
