why do ram and pcie slots have tiny holes in the sides of the hole where you do insert the card?

[12345678]

is it because for manufacturing purpose, or do they have an actual use? which is it?

Tiny holes? You mean where the locking fingers grasp it to hold it in securely? In that case it's, well, to hold them in securely.

1. To hold them in place.

2. To keep Pakleds from inserting them backwards and bugging customer support with, "My computer is broken. Can you make it go fast?".

@aisle9 I meant those holes

Thats where the metal pins go in.

Indeed for manufacturing.
 

Edit:
You should be able to see the metal (mostly copper or similar) pins move back and forth when inserting RAM sticks on those slots.
 

 

IMO I dont see any reason to have them open BESIDES to be able to diagnose a broken pin.

Oh those. In that case, what @HanZie82 said.

Probably because it's easier to manufacture this way and also to save plastic. 

 

Generally speaking if you look at any plastic product you'll find all sorts of holes, cutouts, dimples and other things that are essentially "the absence of plastic". It's usually either because it somehow makes the manufacturing process easier (eg a simpler and cheaper mold) and or because they will do anything to save every last gram of plastic, which makes sense considering you make these products in bulk.

 

If having a hole in a certain place won't affect the utility of the product, but it'll save you 10% in material cost, that means if your plant buys 1 ton of plastic per month you'd save 100kg and you can still sell it for the same price.

Yeah that's where the pins go in
