Capcom Ball Trough Board Set (CPCM-TT and CPCM-TR)













Board Set

These boards are complete redesigns of the B0015601 and B0015701 ball trough boards that fit the following Capcom pinball machines:

As with other ball trough boards, the Capcom boards suffer from high heat and less than ideal circuit board construction. Where the WMS style used large 2 watt resistors to help with heat dissipation, Capcom used 1/4 watt resistors, which have less surface area, but on the plus side, less mass, so they don't vibrate off like the WMS ones!

The high heat put out by the resistors can cause premature failure of the infrared optos. This typically results in multiple balls in play or endless multiball.

The newly redesigned board has a number of significant advances that improve over the original:

  • Less heat generated - about 20 degrees cooler than original boards!
  • Better board construction with large traces and pads for more reliability.
  • Better IR efficiency. Output power of the infrared opto transmitters is over twice that of the original boards without any additional current consumption!
  • Visual status LEDs have been added to the transmitter board and are easily checked from outside the machine! One green LED shows the health status of the one IR LED chain. One red LED indicates power being delivered to the board.

The above two images show the remarked difference between the original board and the new design!

In the following images, we took temperature readings of the old transmitter board and the new one. Each board was left running for 5 minutes and the board was scanned for the hottest spot before the picture was taken.

Picture 3

That's 114 degrees Fahrenheit!

Picture 4

The new board is a much cooler 95 degrees Fahrenheit!
