It is not too difficult to assemble this board as the printed circuit board can be purchased ready-made and acomplete set of components can be ordered using the ordering system set up in the WorkingWatercar forum.You should notice here, that the whole of the aluminium case is being used as a “heat-sink” to dissipate theheat generated in the FET driver transistors. These transistors are all bolted to the case and each has it’sown rectangle of mica “washer” between the transistor and the case. These pieces of mica pass heat veryreadily to the case, while at the same time, isolating the transistors electrically so that they will not interferewith each other. Notice too, the plastic support columns at each corner of the printed circuit board. Theseare used to mount the printed circuit board securely, while holding it away from the metal case and sopreventing any possibility of the connections on the underside of the board being short-circuited by the caseitself.In some of the builds of the electronics board, it has been found that it is sometimes difficult to get the highestfrequency oscillator operating correctly at around 42.8 KHz due to some NE556 chips being out ofspecification. Even though they should be the same, chips from different manufacturers, and even the samebranded chip from different suppliers, can have slightly different actual specifications. On both the PWM3Eand PWM3F boards, C4 has now been changed from 0.1 microfarad back to 0.047 microfarad toaccommodate the corrected specs of the newer Texas Instruments NE556N chip (the one marked withMALAYSIA on top). The earlier versions of the NE556N chip had required a change to 0.1 microfarad tocorrect for specifications that were sub-standard. Depending on which chip you actually use in the “U1 - U3”19
