Procedure of assembly wiring (2/13)
Mount the diode D2
Mount D2 to 15F and 15I from parts side. The diode has polarity.
The component lead of the cathode side(line marked side) must be put to 15I.
Bend the lead of 15I side to 15H, and bend more from 15H to 16G.
When you bent the component lead, confirm that the part is installed in the parallel to printed board.
You should always confirm this.
At 16G, there is the component lead of IC socket. Then cut the component lead of D2 so as not to overlap with the lead of IC socket.
Bend the lead of D2 of 15F toward 14F a little.
Hold down D2 from the parts side, and adjust the angle of the lead of D2 of 15F side, and put the lead of 15I side lead of D2 to 16G.
It is a little difficult.
Solder the lead of 16G of D2 and the lead of IC socket together.
Cut and leave about 0.5 mm the lead of 15F of D2 that is bended toward 14F so as not to contact with surrounding land.
Mount the resistor R2
The resistor dose not have polarity. But when you mount it on the purinted board, it is beautiful and easy to read that the same direction of color code. There is no problem even if it is put conversely.
Mount R2 to 14E and 14H from the parts side.
Bend the lead of 14E to 15E, and more to 16F. At 16F, there is the lead of IC socket. Then cut the lead of R2 at 16F so as not to overlap with the lead of IC socket.
Although the lead becomes oblique from 15E to 16F, it does to pass the center of 15F and 16E.
Hold down R2 from the parts side, and adjust the angle of the lead of R2 of 14H side, and put the lead of 14E saide lead of R2 to 16F.
Solder the lead of 16F of R2, the lead of IC socket and the wire passing under the IC1 together.
Bend the lead of 14H to 14G, and more to 15F.
At 15F, there is the lead of D2. Then cut the lead of R2 at 15F so as not to overlap with the lead of D2.
Solder the lead of 15F of D2 and the lead of R2 together.
Solder the lead of 14E, 15E, 17E, 14G and 14H to the turn.
Soldering of 15E, 15F, 16E and 16F is in the place which approached, then it does so as not to contact with the neighbour.
In the case that it has contacted to the neighbour with too many solder, solder is decreased by using soldering sucker. After that, solder again.
