Cheap?

It is interesting how early the first ICs came along
Elijah Jones
Yeah OP is a nigger pseud. This in nothing but a ching ching dollar store radio from the 90s early 2000s before digital tuners really go vanishingly cheap. Hell it might even be modern as these are still made for and by third worlders.
We had better looking boards in the 60s. This is just cheap shit.
John Torres
You're kinda joking, right? ICs were used in the 60's already in concumer gear, in the 70's and 80's already is pretty cheap concumer gear.
That's a PCB from probably 15-30 years ago, not early at all for IC's.

This.
Luke Jones
didn't realize this is cheap chink shit with old parts for the time, that explains the mismatch
in the 60s were it already chips? or just transistors
Zachary Rodriguez
Imagine the smell.

>old parts for the time
Not even "old" as in the parts being made a long time ago, just parts that have been made for a long time because they are cheap and work.
ICs are transistors on a substrate. Basic glue logic in DIP packages that only have a few transistors in them are still used to this day.

I don't.

Through-hole?
You can still make boards of your own like that if you like.
Makes less sense frequence, if trace capacitance, board space, cost, etc is of concern.

All late 60s tuners I ever owned had the entire multiplex circuit in an IC. Most of these also used a chip based denoiser.
I also had and have many 70s devices that have 90% of their caps in spec. The problem is not the cap, it's chinks.

They're still common in cheap power circuitry

I miss when they used to use lead in solder. Fuck the EU.
IDK of any practical advantages of lead-free in an end product
Jonathan Parker
lead solder gave us retards like you
Bentley Young
now it's all (((integrated)))

Leaded solder is so much easier to work with it's mental. I used to use it for reworking at a previous company, flows so smoothly.
