... MOUNTING INSTRUCTIONS The R of the L293B and the L293E can be reduced by soldering the GND pins to a suitable copper th j-amb area of the printed circuit board as shown in figure external heatsink (figure 13). During soldering the pins temperature must not exceed 260°C and the soldering time must not be longer than 12 seconds ...
