My guess is that they have flex cables (and not so much ribbons) and tape. Other electronic devices - including modern ones - that I've taken apart lately include quite a lot of both.

There are three flexes in just this one iFixit photo of one side of a Switch Lite: https://d3nevzfk7ii3be.cloudfront.net/igi/sbTwHYTEZOaWX3IQ.f...

Tape takes a number of forms. Holding down flexes to manage pull-out forces is pretty common. You can do that with traditional single-sided tape if you have the space on something to adhere it, but increasingly common is a double-sided tape on the flex itself. You peel off a liner and stick it down. It wouldn't surprise me if there are liner-less heat-activated tapes too, but I don't know of them myself. That's outside my domain.

I changed the board on my 3D printer today, the biggest hurdle was all the wire and plug manipulation. I play guitar, piano, type all day, you'd think I'd be good at it. It was like trying to pick up a grain of rice with two cucumbers.

When I work with this type of thing I use different kinds of tweezers (chip pullers, flat/round end, angled, etc). The ends of most FFC/FPCs are reinforced partly to provide good contact in their mating connector and also to make it easier to insert the cable with enough force without damaging it.

The spiky-ended tweezers will damage an FFC though.

Really. A dot of hot glue to hold a cable down must be easier.

All the manufacturing engineers I've talked to hate doing fluid dispense. Glue is in a class all its own because if you take the line down it tends to cure in the dispenser or nozzle.

Fluids/moltens are a nightmare.

The PS4 officially supports replacing the internal hard drive, and that's not even getting into the question of repairs

If I could have one change to electronics manufacturing, it would be a ban on glue for non-waterproof devices. Most repair-hostile trend in history.

I took apart my PS4 Pro several times since I own it. It’s very easy to do, nothing is glued, and the plastic clips that hold the cover in place don’t break when you unsnap and snap them back.

The only thing is an obnoxious warranty void sticker that delaminates if you don’t lift it carefully but even then I don’t think it’s legal to void the warranty with a sticker (Switzerland, bought from a EU retailer)

You can get replacement stickers for around $10 on eBay. Sadly the PS4 line looks a lot better with the stickers on as they hide exposed screws.
