2.5 Assembling the Printed Circuit Board
After placement of the extended plug sockets (and eventually the plug arrays as well), you may
remove the PCB and complete the assembly phase. According to the component placement drawing
(see fig. 12) you are advised to proceed the following way: Up to R7 all resistors are to be placed
upright – according to the ASURO-standard, which implies bending a U-turn (180° ) for one leg of
the components. Bend both legs for component R7 at an angle of 90°.
Fig. 12: Component placement drawing
Please insert the components in the following sequence:
IC1: Initially merely insert the socket, be careful to apply the correct polarity!
D1, D2, D3: 1N4148, be careful to apply the correct polarity!
C4, C5, C6: 100nF ceramic
R1, R2, R3, R7: 10kΩ 5% (brown, black, orange, gold)
R4: 220Ω 5% (red, red, brown, gold)
R5: 1kΩ 5% (brown, black, red, gold)
R6: 100kΩ 5% (brown, black, yellow, gold)
C2, C3: Electrolytic capacitor 100µF, minimal 16V, be careful to apply the correct polarity!
TR1: Spindle-trimmer 20k upright
D4: LED 5mm rot, be careful to apply the correct polarity!
CON1: screw terminal, cable entry must point to the PCB-edge.
IC1: Now insert the TS912 into the socket. Maybe you will have to bend the legs slightly. Be
careful to apply the correct polarity: the marker at the component must be oriented to the
corresponding marker at the socket!
