Things i am looking for
- Dry transfer pcb footprints and transistor shapes ( Like Seno graphics or Radio shack or deca-dry ) 276-1577
- Rubylith pcb drawing
- Black masking tape rolls ( different widths ) used to make PCB films ( bishop graphics, also their 'puppets' and donuts)
- 4:1 scale transfer symbols , or any PCB layout drawing made using a 4:1 scale setup. ( not the pcb , but the film drawing. ) things like the transfer film , the grid foil etc ...
if you want to know what i am talking about see
https://www.youtube.com/watch?time_continue=667&v=7weZ0TNRcuw timestamp 3:13 : the ruled grid, the drafting film , the component templates . time index 6:14 : the pads , the tape. I want to get such a layout film. Doesn't matter what it is for. Either a film or a high resolution picture.
- circuit boards using the following processes :
- silver ink via process.
http://www.dawee.co.id/sub32.html . this was commonly used in cheap mass consumption products such as remote controls, calculators etc.
- rivets and cups used for thru-metaliisation. This was popular in the late 70's and early 80's in european TV sets. I remember boards that had these. typically they had round, orange or brown electrolytic capacitors in them made by siemens and they were a bitch to remove. the rivet was flat on one side and had 4 prongs on the other side. same time era as when ITT had those yellow 3 pin line input filters in TV's that would blow up ...
- ceramic pcb's ( grundig had those ) i am NOT talking hybrids !
- pictures of early pcb's ( 50's , 60's , 70's ) with distinctive looks like
(the copper pattern is reproduced as silkscreen ...)
- carbon or silver printed ink layer-on-layer boards ( not the carbon used for those rubber buttons, but carbon traces or silver traces printed on the copper side , on top of the soldermask , to create a multilayer board. it is a single sided board but they use the printed carbon ink or silver ink to create a second layer.
any 'interesting' looking board. meaning : deviates from classic circuit board manufacturing techniques
- cordwood module
i need either the actual boards ( willing to pay for shipping ) or a copyright free picture. ( don't send me stuff found on the internet., can't use that, even if it is creative commons )
