i see there are 2 option machine tooled and dual wipe. What are the diferences and which one should be used on game board pcbs
 
Funny you should ask. I was having this discussion last night with a fellow KLOV'r and we both agreed that machine pin sockets are evil. Use dual wipe. Plain and simple. If you solder a machine pin socket onto a board, it is tough to remove with that extra shoulder. Also, square pegs don't fit in round holes. With that being said, if you have a machine pin chip, put it in a machine pin socket. Please, please please use dual wipe sockets and save out chips. Nothing worse than snapping off a leg in a machine pin socket. Especially chips off Galagas that are corroded or pole position. I have said my peace. Flame away.
 
Huh, I thought for sure the answer would be machine pin. I use them all the time. The original boards used wipe pins and those fail all the time due to heat, dust collection, and corrosion issues.
 
Well this thread has now caused me added grief, as I bought my first-ever pcb sockets from the local electronics shop and with them at home, I have no idea what I bought.

I tried Googling to see the diff between the 2 types but I'm not getting very far. The sockets I bought have the holed entry on the top for the chip, and the plain old straight pin to stick through the circuit board.

Hopefully I have chosen wisely. Matter of fact, what I bought was all they had! :(

Yeah, there's a reason that machine-pin are also known as "high reliability" sockets. They are not inherently evil... although I have seen evil things done with them....
I agree that a decent dual-wipe socket is good enough, and easier for a novice to deal with.

Ah... but many original boards used *single* wipe sockets. Not dual wipe. And even the ones that did have dual wipe sockets, tended to have very poor quality ones. TI made some truly horrible sockets. Some only grab the sides of the pins...

Modern, good quality dual wipe sockets are far superior to the old ones.

For removing machine pin sockets, I take diagonal cutters and snip the plastic in between pins into sections about every 3 pins. (basically breaking the plastic socket up) then I heat all 3 pins with the iron at once and pull them out.
