Accessories:
Solid Capacitor:
Capacitance: no less than 820UF;
Voltage: no less than 2V;
ESR: 0.0285@120Hz;
Packaging: in-line package
Quantity: 4
Soldering
1. Preparation for Capacitor:
Distinguish the negative pole in solid capacitor: the point marked with
red (see S2-1);
Bent the pins of capacitor to a proper direction for soldering (see S2-2);
Cut off pin length to 2-3mm (see S2-2, S2-3)
S2-1
BITMAIN
S2-2 pin marked in red is negative pole
S2-3
BITMAIN
2. Soldering
Distinguish the positive pole and negative pole. The pin marked in red is
negative pole (see S2-4)
S2-4
As show in S2-5, it marked where the negative pole of 4 capacitors should
be soldered. Must pay attention to positive and negative pole.
