OK, so I'm playing a game and going really well - next thing the left flipper starts acting up - WTF!
Lift the playfield, snoop around looking for the obvious, broken wires, diodes across the coil - the usual suspects. Nothing. Look in the backbox at the fliptronics board, connectors all seem OK, nothing is obviously frizzled????
Go back to basics and start at the actual switch. I remember that these optos do cause problems on the actual flipper button board so I rip it out and lo and behold - the board is covered in corrosion! I cleaned it up as best I could and resoldered a few suspect joints. Bridged one track that was very suspicious. Put it all back together and BINGO! All spot on. So in this case the optos are fine but the PC board has corroded.
I trawled the usual suppliers and the best price I could find was $34 each - ridiculous for such a small board with 2 resistors, 2 optos and a connector on it!
So this became the next Homepin project - jumping the cue of other boards we are making. Artwork is complete and already submitted to the PCB fabrication factory. Finished boards should be about 2 weeks and I estimate a pair should cost about $39, maybe a few dollars more depending on the final costs.
We added some test points for checking 12V right at the board and also have made up a laser cut insulator to install between the board and the metal flipper actuator to help prevent a repeat of the corrosion.

A pair for the price of one your really goin to start shaking things up mike well done
-
Good one again Mike. ^^^
Any plans to do a combo board to replace Williams SYS6 CPU and Driver boards .. or it could be a SYS7 board .. specifically I ask with Firepower in mind && but there's also Gorgar etc
Cheers

It was pointed out to me by an astute reader that I had the part number wrong - I was able to quickly supply revised artwork to the PCB factory - Whew....
No changes other than the part number:::

Good work and a fair price,could never understand why type1 PCb's where so expensive compared to type2's #*#

Nice work again Mike ^^^

You are making me jealous with all these remakes.
looks like i might have to start making some artworks up my self.
Well done on another useful board.

Keep up the good work,

Another great product, Mike - well done !

I've laser cut a couple of dozen sets of 'fishpaper' insulators ready for the arrival of the blank boards:

Hi there

should only be a couple of weeks as they are pretty simple. I am also waiting for the 7 pin .100" connector but I already have the optos in stock.
